Capacitors

In our BS- and CECC-approved UK based production facility, Charcroft Electronics manufacture a wide variety of Capacitors, which include Silver Mica and BS/CECC-approved radial multilayer ceramic capacitors (MLCC’s). Charcroft’s acquisitions of Beck/Oxley Developments and TAB Components have served to extend our repertoire of Silver Mica Capacitors. Charcroft manufacturing facility can also offer custom passive assemblies. Please contact us for any further information.

Charcroft Electronics manufactures the following Capacitors:

Silver Mica Capacitors

radial-dipped-silver-mica-capacitors

Dipped Radial

All capacitors are encapsulated in thermo setting resin to provide excellent humidity and mechanical protection. In addition these devices are moulded with 'stand-off' feet to ensure flux vapours escape and stability is ensured during flow soldering. The encapsulation and coding materials have been specially selected to ensure they are not affected by solvents commonly used for cleaning and flux removal on PCB's. Terminations are tin coated copper wire and meet the requirements of BS2011 robustness of termination.

Dipped Radial

These capacitors are specially designed for audio applications. Constructed from the finest Indian Ruby Mica plates, they are cut by hand, then have silver electrodes printed on. The plates are stacked to the required value, have their edges reinforced with silver paste and are then sintered at 560°C. After firing they are cut into individual chips ready for lead attachment. To enhance their audio properties, solid silver lead wires are attached before final trimming and dipping in epoxy resin. These Capacitors are fully assembled and individually trimmed by hand in our UK based manufacturing facility.

SBH-Radial-Dipped-Capacitor

These capacitors are specially designed for use with transmitter filters of up to 1kW power output. Any capacitance value can be supplied within the range stated below in 1pF steps. Capacitance tolerance is ±1pF up 100pF and ±1% above. Capacitors are designed to operate at RF and will run cool under normal transmitting conditions. All materials used in their construction are non ferrous therefore minimising inductive effects and subsequent heating of capacitors and other components in close proximity.

SB1-Moulded-Capacitor SBA108-Moulded-Capacitor

The SB1 and SBA108 capacitors have a low loss dielectric, making it suitable for use in equipment such as transmitter filters which involve high alternating voltages, high frequencies and high currents. The internal construction of the capacitor ensures that the rated voltage is well below the voltages where ionisation discharges occur.

A very small change in mica capacitance with temperature ensures that the capacitance remains within the stated tolerance over the entire working temperature range.
