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.
TT Electronics, a global provider of engineered electronics for performance critical applications, today launched the HA19 series of common mode chokes for use in electronic power steering (EPS) noise suppression applications. With high performance and AECQ-200 certification, the HA19 series are ‘automotive ready’ for the new generation of motor vehicles.
Every EPS system requires proper EMI (electromagnetic interference) control with a common mode choke (CMC) and/or a differential mode choke (DMC) serving this function. With the growing shift to EVs and PHEVs, and the accelerated incorporation of electronic components in automobiles, noise suppression has become increasingly important in order to ensure EMI compliance. TT Electronics’ HA19 series common mode chokes are designed with the company’s extensive expertise and excellence in noise suppression performance in chokes that the company has supplied for EPS applications over the last 15 years.
The HA19 series is comprised of three parts with standard inductance values, ranging from 11µH to 75µH, and has been demonstrated to be ideal for reducing line-conducted inference in the circuitry. The HA19 series devices offer high reliability and superior current handling from 26.5A to 44A (and even higher over-current withstanding) in a rugged construction. Their wide -40 to 125°C operating temperature range and AEC-Q200 certification make them ideal for high stress automotive environments. The HA19 common mode chokes are lead-free and comply with EU Directive 2011/65/EU (RoHS2) requirements.
