The following table represents our standard listing of MLC’s produced from our ultra-stable EIA Class I COG dielectric. In addition to the above 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.

COG capacitors are very well suited to applications requiring extremely stable electrical properties given time, temperature and voltage. Common applications include aerospace, defense, pulse energy detonation and higher end consumer needs requiring a greater degree of safety/reliability.

In addition to the above 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.

Class II X7R capacitors are very well suited to applications allowing for predictable changes in electrical properties given time, temperature and voltage. A temperature coefficient of ±15% is standard and typical results are detailed above. Common applications include aerospace, defense, pulse energy detonation and higher end consumer needs requiring a greater degree of safety/reliability.
