Nichicon UES1H331MHM Muse ES Series Audio Capacitor, 330uF 50V, Bi-Polar Radial, 16x31.5mm - Pack of 20

The Nichicon UES1H331MHM is a premium bi-polar (non-polarized) aluminum electrolytic capacitor from the prestigious "Muse" ES series. Engineered specifically for high-fidelity audio applications, the Muse ES series is a benchmark in the industry, favored for its ability to produce a rich, transparent sound with exceptional resolution. Its bi-polar design allows for high-performance signal handling in circuits where polarity may reverse, making it an ideal choice for audio signal paths, coupling, and speaker crossover networks.

Key Features

• True Audiophile Grade: Part of Nichicon's specialized Muse family, designed with selected materials to achieve superior acoustic clarity and minimize harmonic distortion in high-end audio gear.
• Bi-Polar (Non-Polarized) Performance: Engineered for horizontal symmetrical circuits. It eliminates the need for polar orientation and ensures clean AC signal passage without the distortion characteristics of standard polarized capacitors.
• Acoustic Integrity: Features a low dissipation factor (0.12) and ultra-low leakage current (3 µA), ensuring that the audio signal remains uncolored and original musical nuances are preserved.
• Thermal & Operational Stability: Rated for operation from -40°C to +85°C with a 1,000-hour load life, providing durable and consistent performance in professional power amplifiers and pre-amps.
• Precision Form Factor: Large 16x31.5mm radial package with 7.5mm lead spacing provides a robust mechanical footprint for high-current through-hole PCB designs.
