Ampohm FP-CA-AU Audio Series Film Capacitor 1µF, 630V, PP, ±5%

The Ampohm FP-CA-AU Audio Series Film Capacitor is a precision, axial-leaded component designed specifically for high-fidelity audio applications. Constructed from metallised polypropylene (PP) film, this 1µF capacitor is hand-wound under tension control for optimal electrical characteristics, resulting in exceptionally low ESR (Equivalent Series Resistance) and low inductance. These properties are critical for preserving signal integrity and achieving pure, uncoloured sound reproduction.

Each capacitor features hand-soldered internal connections to insulated copper lead-out wires, ensuring reliable and robust electrical performance. The assembly is then housed within a rigid, resilient plastic case and sealed with resin, which also serves to identify the outer winding. This meticulous construction grants the capacitor high stability across both a wide temperature range (-40°C to 85°C) and a broad frequency spectrum, making it exceptionally consistent in demanding environments.

Ideal for discerning audiophiles and professional audio engineers, this capacitor excels in applications where sonic purity is paramount. It is a premier choice for use in loudspeaker crossover networks and valve (tube) amplifiers, where its precise capacitance and stable performance contribute significantly to a clear, detailed, and dynamic audio output. The through-hole mounting design facilitates secure installation in a variety of audio circuit boards.
