KEMET’s New Surface Mount Safety Certified Ceramic Capacitors Provide Solutions for Space Constrained Mains Powered Applications

New devices offer smaller form factors to save space and simplify manufacturing versus competing leaded devices in AC line filtering applications

KEMET has launched a new range of surface mount device (SMD) safety certified multilayer ceramic capacitors (MLCCs) for use in mains powered applications. The CAS series addresses widespread demand for miniaturization without compromising performance by offering higher capacitance, smaller overall size, and simplified assembly versus existing leaded disc devices, which represent the majority of safety-certified ceramic capacitors currently on the market.

According to market research*, the overall power supply sector is expected to grow to US $34.92 billion by 2023, at a CAGR of 6.7% from 2018 to 2023. Within this, AC/DC power conversion is considered the largest and fastest growing type of power supply owing to its increasingly wide range of uses and applications. KEMET’s CAS series of SMD MLCCs offers important design and production benefits versus leaded disc devices for AC line filtering in this significant and expanding market.

To satisfy industry and consumer demand for portable solutions, PCB real estate for electronics and power delivery systems continues to shrink as designers put more functionality in smaller spaces. Commonly used safety certified leaded disc components are bulky compared with KEMET’s CAS series SMD MLCCs and are often not suitable for applications with restricted spaces in which filtering circuitry needs to be placed. Leaded disc devices also require pin-through installation into PCBs, a process that is not compatible with standard automated reflow profiles and therefore can result in additional production costs.

Filtering is important in mains powered products to manage unwanted transients, such as high frequency noise in both line-to-line (Class X) and line-to-ground (Class Y) applications. Safety certified capacitors are used in a wide variety of applications, such as power adapters for mobile devices, industrial power distribution, and electric vehicle power inverters.

“Until now, safety certified capacitor technology has not kept pace with advances in MLCC technology,” said Reggie Phillips, KEMET Senior Product Manager. “Our new CAS range allows engineers to place the essential mains-connected filtering capacitors into smaller spaces, thereby reducing board size. For manufacturing professionals, the benefit is that the new devices are compatible with standard reflow processes, eliminating an additional step in the manufacturing process.”

Charcroft samples ultra-stable Kemet KONNEKT™ technology capacitors

  • First ultra-stable KONNEKT U2J ceramic capacitors sampling now
  • Enable higher power densities in smaller form factors
  • Leadless multichip for high-efficiency and high-density power converters

Charcroft Electronics Ltd., – a specialist distributor and manufacturer of electronic components for harsh and high-end applications – is sampling the first release of Kemet’s KONNEKT technology capacitors. KEMET’s patented KONNEKT™ technology is designed to enable high power density by combining multiple components into a single surface-mountable package.

The KONNEKT U2J ceramic capacitors feature KEMET’s ultra-stable U2J dielectric to create a low-loss, low-inductance package capable of handling very high ripple current in the range up to hundreds of kilohertz.

The leadless multichip solution for high-efficiency and high-density power converters uses innovative Transient Liquid Phase Sintering (TLPS) which makes the capacitors compatible with existing reflow processes. The option to mount the KONNEKT U2J capacitors in a low-loss orientation increases their power-handling capability. It also provides lower Effective Series Resistance (ESR) and Effective Series Inductance (ESL) in addition to increasing the capability to handle ripple current.

The extremely stable KONNEKT U2J Class I dielectric material exhibits a negligible shift in capacitance across voltage and a predictable and linear change in capacitance across ambient temperature, with minimal aging effect. The family operates over a temperature range from −55 to +125 degrees Centigrade.

KONNEKT U2J capacitors are sampling now from Charcroft Electronics for qualified high-efficiency, high-density power converter designs. Samples can be requested from

NEW PRODUCT: KONNEKT U2J for High-Efficiency, High-Density Power Applications (Commercial Grade)


TKEMET's U2J KONNEKT surface mount capacitors are designed for high-efficiency and high-density power applications. KONNEKT utilizes an innovative Transient Liquid Phase Sintering (TLPS) material to create a leadless multi-chip solution. When combined with KEMET’s ultrastable U2J dielectric, KONNEKT enables a low-loss, lowinductance package capable of handling extremely high ripple currents in the hundreds of kilohertz. U2J is an extremely stable Class I dielectric material that exhibits a negligible shift in capacitance with respect to voltage and a predictable and linear change in capacitance with reference to ambient temperature, with minimal aging effect. Capacitance change is limited to –750 ±120 ppm/°C from –55°C to +125°C. U2J KONNEKT can also be mounted in a low-loss orientation to further increasing its power handling capability. The low-loss orientation lowers ESR (Effective Series Resistance) and ESL (Effective Series Inductance) which increases ripple current handling capability.

High reliability thick-film resistors

TT Electronics, a global provider of engineered electronics for performance critical applications, has announced the introduction of two additional resistor types that expand and enhance its high reliability CR and HR series. The latest versions of these thick-film chip resistors are in the smaller 0603 size and hence offer greater opportunities for use in compact circuits where guaranteed performance and footprint size are critical.

For use in applications in the aerospace, military, communications, medical and industrial market segments, both resistor series’ thick-film elements have a higher surge tolerance than thin-film, also improving reliability. The CR0603 resistors are available in values from 1R0 to 10M with tolerance values down to 0.1 percent, and have the option of release to CECC 40401-008. In addition to military and aerospace use, particular applications include sub-sea repeaters, mainframe systems and Hi-Rel systems. The HR0603 resistors are available in values from 10M to 20G with tolerance values down to 5 percent supporting applications that include high gain amplifiers, infra-red and glass break sensors, plus smoke, gas and medical monitors.

TT Electronics’ CR series resistors’ optional screened release enhances reliability and reduces field failures, and for circuit designers who need to guarantee the reliability of critical circuits in compact PCB areas they provide low demonstrated FIT rates compared to competing commodity products. Seven sizes are now available from 0503 up to 2512. The CECC approved resistors are also available as shorting links.

The HR series high ohmic value resistors offer enhanced reliability and reduced field failures compared to series connected, multi-chip solutions for circuit designers who need to achieve stable, high ohmic values in compact PCB areas. The resistors offer a low voltage coefficient of resistance and, demonstrating versatility, custom designs and sizes are available. As a high resistance device, power dissipation is always small, hence the rating is determined by voltage considerations only, and varies from 50V for the smallest 0503 resistors, to the 200V for the largest 1206 sizes, and five sizes are now available.

Class 2 MLCC dielectrics and the case of the missing capacitance.


Most designers selecting an MLCC for their application will be familiar with the dielectrics being described as class 1 or 2, but may not be totally familiar with what this actually means, or what impact it can have. MLCCs are often advertised with their temperature co-efficient of ceramic (TCC) figure, but their voltage co-efficient (VCC) is often overlooked or ignored. In practise, even the TCC figure can be misleading and the VCC figure can have a much larger impact on the actual effective capacitance of the part. Here we consider what the 2 different characteristics actually mean, and what impact they can have.
