Cornell Dubilier's standard dipped silvered mica capacitors, like the CD15ED270JO3F, are ideal for timing and close tolerance applications where stable capacitance over a wide temperature range is crucial. These capacitors are widely available and offer high-temperature performance up to +150 ºC, meeting EIA RS153B specifications and exhibiting a minimum 100,000 V/µs dV/dt pulse capability. They are commonly used in precision circuits, oscillators, and filters where stability and accuracy are paramount.
