Mundorf ECAP63-390 | 390 µF | 5% | 63 V

The Mundorf ECap RAW ECAP63-390 is a premium non-polarised electrolytic capacitor engineered for discerning audio enthusiasts who demand uncompromising signal purity. With a capacitance of 390 microfarads and a voltage rating of 63 volts, this component excels in high-fidelity loudspeaker crossover networks, where it ensures accurate frequency division and minimal phase shift. Its non-polarised design makes it equally suitable for DC-blocking applications, protecting sensitive drivers from offset voltages while preserving the integrity of the audio signal.

This capacitor is ideally deployed in passive crossover filters, tube amplifier coupling stages, and signal-path upgrades in vintage or modern hi-fi equipment. The axial lead configuration simplifies installation in point-to-point wiring or printed circuit boards, offering flexibility for custom builds and repairs. The tight ±5% tolerance guarantees consistent performance across channels, critical for stereo imaging and tonal balance.

Technical highlights include a robust 25 x 38 mm aluminium casing that provides excellent thermal stability and low equivalent series resistance. The electrolytic construction delivers high capacitance density without the bulk of film types, while the non-polarised nature eliminates the need for orientation, reducing assembly errors. Rated for 63 volts, it comfortably handles typical audio signal voltages with ample headroom.

For the serious audiophile or technician, the Mundorf ECAP63-390 represents a reliable, sonically transparent choice for refining system performance. Its precision and build quality make it a worthy upgrade for any signal-critical application.
