Dedicated pulse discharge MLC capacitors offer exceptional reliability

Dedicated pulse discharge multilayer ceramic chip capacitors for munitions, ordinance, and oil field exploration and perforation are available from Knowles Capacitors brand, Novacap. These capacitors offer the exceptional reliability afforded by ceramic multilayer fabrication using advanced ceramic and electrode formulations, with thin, dense and precise dielectric layers to satisfy unique and difficult requirements with unsurpassed quality. Energy density exceeds that of conventional Class 1 materials and offers excellent short duration pulse delivery at temperatures to 200C. These high temperature, high energy, capacitors are manufactured with a dielectric formulation designed for reliable operation under single or repetitive high energy, multiple pulse, firing into typical EFI and LEEFI circuits where resistive loads are in the 0.1ohm to 0.25ohm range. Discharge pulse width, which is typically less than 100 nanoseconds, will vary with load conditions which are influenced by inductive and resistive load components. With exceptionally low ESR and low signal distortion, additional applications at high temperature include power supply filtering, energy storage and coupling/decoupling. All parts are 100% pulse screen tested and are evaluated at temperature extremes up to 200ºC consistent with munitions and oil field exploration/seismic detonation conditions. As an added safety feature, these pulse energy capacitors can be supplied with integral bleed resistors at various resistance values.
