N2200 Fuze Capacitors

Table of Maximum Capacitance Values for Custom Chips

Class I - N2200 (R) Dielectric

The following table represents our standard listing of Pulse Energy/Detonation (Fuze) capacitors produced from our proprietary N2200 dielectric formulation. In addition to the below listed standard case sizes, WCI is ideally situated to custom fabricate alternative size, thickness and/or voltage ratings per individual requirements. Should you not find what you are looking for please call the factory.



Produced according to meticulously defined standards, all parts are then conditioned at elevated temperature and voltage. 100% of all lots are screened for conformance to stated performance criteria. All units are tested to MIL-PRF-49467 however customer required screening can also be accommodated.

Our high reliability line of N2200 capacitors are specifically designed to withstand the rigors of single or multiple pulse firings.

A temperature coefficient of 2200 PPM is standard and typical results are detailed below. Common applications include aerospace, defense, pulse energy detonation and higher end consumer needs requiring a greater degree of safety/reliability not usually found in “cots” parts.

Fuze Capacitors Brochure
This is the Class I temperature compensating dielectric. N2200 is non-piezoelectric and particularly well suited for repetitive high current pulse type applications (where long charge/discharge life is required). N2200 also has no voltage coefficient, which makes it more volumetric efficient than X7R at higher voltages. Also, the lower ESR (DF=.1% typical, X7R=1.8% to 2.5% typical) as well as increased capacitance at lower temperatures is an additional benefit in many applications.






As a safety feature an integrated bleed resistor can be included on the capacitor. This can either be a single resistive element or dual for redundancy purposes. Typical resistance values range from 100MΩ to 500MΩ at ±20%. Although other values and tolerances can be specified. Resistors are stable up to 200°C.

Fuze caps with an integrated bleed resistor will be coated with our clear, high temperature, high voltage and moisture resistant protective coating. All other fuze caps will be coated with our red urethane varnish.
