The 225P15391WD3 is a Type 225P Orange Drop polyester film/foil capacitor designed for reliable operation in demanding environments. This radial-lead capacitor features a 0.018 µF capacitance value with ±10% tolerance, rated for 100 VDC operation, and operates across a temperature range of -55°C to +85°C at full voltage. The capacitor employs non-inductively wound, extended foil construction with a conformal coating of orange, flame-retardant epoxy meeting UL94V-0 specifications, and exhibits a maximum dissipation factor of 0.75% at 1 kHz and +25°C. With tinned copper-clad steel leads (#20 AWG, 0.032 inch diameter) and a lead spacing of 0.562 inches (14.3 mm), this component is ideal for audio equipment, vintage amplifiers, and precision analog circuits where the Orange Drop's legendary reliability and sonic characteristics are valued.
