Overview
The Mallory 03193890 is a Type FP aluminum electrolytic capacitor engineered for DC applications requiring stable capacitance and reliable performance. Rated at 400MFD (microfarads) and 150VDC, this vintage unit from January 1986 is a drop-in replacement component for legacy audio, video, industrial control, and power supply circuits. Type FP capacitors are known for consistent performance in filtering, smoothing, and energy storage applications.
