UFG1A331MPM

The UFG1A331MPM is a 330 µF, 10 V polarized aluminum electrolytic capacitor from Nichicon’s UFG "Fine Gold" MUSE acoustic series. It is a radial‑lead, can‑type capacitor engineered for high‑grade audio and AV equipment, offering audio‑focused etching and construction aimed at richer bass and clearer high end.

Designed for general‑purpose use within audio systems, this part combines compact dimensions (1.25 × 1.00 cm) and 5 mm lead spacing with electrical characteristics selected for signal and power applications in consumer audio and AV assemblies. The part is RoHS compliant and rated for operation from −40 °C to +85 °C.

Key Features

• Audio‑oriented "Fine Gold" MUSE series State‑of‑the‑art etching techniques for tonal characteristics described as richer bass and clearer high end, targeted at high‑grade audio and AV applications.
• Electrical rating 330 µF capacitance at 10 V DC with ±20% tolerance (measured at 120 Hz, 20 °C).
• Low‑frequency loss (tan δ) Series specification for 10 V: tan δ (max) = 0.19 at 120 Hz, 20 °C.
• Ripple current capability Rated ripple current: 247 mA at 120 Hz and 370.5 mA at 10 kHz, suitable for typical audio/AV ripple environments.
• Reliability and endurance Endurance: rated to meet specifications after 1000 hours at 85 °C with rated voltage applied; designed for operation across −40 °C to +85 °C.
• Compact radial can package Radial lead, can package with 5 mm lead spacing and size L: 1.25 × D: 1.00 cm for through‑hole PCB layouts.
• Low leakage current Series leakage specification: after 1 minute at rated voltage and 20 °C, leakage ≤ 0.01CV or 3 µA, whichever is greater.
• RoHS compliant Meets RoHS directive (2011/65/EU,(EU)2015/863).
• Clear component identification Marked with black lettering on a gold sleeve for easy identification during assembly and inspection.

Typical Applications

• High‑grade audio equipment Suited for signal and power stages in premium audio components where tonal characteristics are important.
• AV equipment Appropriate for consumer audio/video systems and components described as AV equipment in the product series documentation.
• General‑purpose electronic circuits Use where a polarized 330 µF, 10 V aluminum electrolytic with radial mounting is required for smoothing, decoupling, or energy storage in low‑voltage designs.

Unique Advantages

• Audio‑tuned construction: The Fine Gold MUSE acoustic series manufacturing and etching approach targets improved bass response and clearer high end for audio applications.
• Compact, board‑friendly package: Small radial can (1.25 × 1.00 cm) with 5 mm lead spacing simplifies placement in densely populated through‑hole PCBs.
• Rated ripple performance: Specified ripple currents at both 120 Hz and 10 kHz provide predictable behavior across common audio and supply‑filter frequencies.
• Operational robustness: −40 °C to +85 °C operating range and 1000‑hour endurance at 85 °C support reliable service in consumer electronics environments.
• Measurable leakage limits: Leakage current specified as ≤ 0.01CV or 3 µA (after 1 minute at rated voltage) for predictable standby and low‑frequency performance.
• Regulatory compliance: RoHS conformity ensures compatibility with restricted‑substance requirements.
