CD5EC270JO3F is a miniature dipped silver mica capacitor designed for low and moderate-humidity applications requiring high stability and rugged performance. This capacitor features a capacitance value of 270 pF with ±5% tolerance (J grade), rated for 300 Vdc operation, and operates reliably across a temperature range of -55°C to +125°C. The unit meets EIA RS153B dimensional specifications with compact form factor dimensions of 0.270 inches length and 0.190 inches height, and demonstrates a minimum dV/dt pulse capability of 20,000 V/µs. The miniature dipped construction provides excellent stability in tight-space applications while maintaining the same performance characteristics as standard dipped mica capacitors, making it suitable for precision instrumentation, signal processing, and other demanding electronic circuits.
