These single feed-thru capacitors with ceramic dielectric class 1 (NPO) or class 2 (2C1 or 2R1) feature unique frequency performance due to very low inductanc inherent to the configuration. They are ideally suited to interconnect power amplifier stages through a shielding wall (high impedance electronic circuits). Silver-palladium terminations (tinned or gold plated as optional) can be directly mounted on the metal surface of the shielding wall. Capacitors intended for use in such applications as aircraft on-board equipment (avionics) are systematically tested to voltage surge withstanding requirement specified in EN 2282 standard.
