CMR03C6R0DOCR Equivalent & Substitute Parts

Part Overview

The CMR03C6R0DOCR is a 6 pF mica capacitor rated at 300 V with radial through-hole mounting. This component is classified as Active and serves general-purpose applications requiring stable capacitance across operating temperatures from -55°C to 125°C. Mica dielectric capacitors are specified when precision and temperature stability are essential. Finding equivalent substitute parts addresses component obsolescence, procurement delays, and inventory optimization while maintaining identical electrical and mechanical performance.
