UFG1E221MPM

The UFG1E221MPM is a 220 µF, 25 V polarized aluminum electrolytic capacitor from Nichicon’s UFG "Fine Gold" MUSE acoustic series. It is a high‑grade standard type designed specifically for high‑grade audio and AV equipment, featuring etching techniques intended to support a richer bass register and clearer high end.

Packaged as a radial lead can with a 5 mm lead spacing and compact footprint (L: 1.6 × D: 1 cm), this capacitor targets general‑purpose audio applications that require verified ripple handling and operation across a -40 °C to 85 °C range. It is RoHS compliant.

Key Features

• Capacitance & Voltage — 220 µF rated at 25 V, with a tolerance of -20% to +20% suitable for typical audio power and decoupling needs.
• Acoustic tuning — Part of Nichicon’s "Fine Gold" MUSE acoustic series; specified to provide richer bass and clearer high frequencies for AV and audio equipment.
• Package & Mounting — Radial lead can construction with 5 mm lead spacing, polarization for correct orientation, and package dimensions L: 1.6 × D: 1 cm for compact board layouts.
• Thermal and lifetime characteristics — Operating temperature range -40 °C to 85 °C with rated endurance of 1000 hours at 85 °C.
• Ripple current capability — Rated ripple handling of 260 mA at 120 Hz and 390 mA at 10 kHz to support audio power signal demands.
• Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• High‑grade audio amplifiers — Used for power supply smoothing and decoupling where a tuned acoustic characteristic is desired.
• AV and home theater equipment — Suited for signal‑path and power sections in consumer and prosumer AV systems looking for improved bass and high‑frequency clarity.
• Professional audio electronics — Applicable in mixers, preamps, and outboard gear that benefit from the UFG series’ acoustic profile.
• General‑purpose electronic designs — Polarized radial lead capacitor for board‑level power and filtering tasks in compact layouts.

Unique Advantages

• Acoustic‑focused performance: The "Fine Gold" MUSE series formulation is specified to enhance bass richness and high‑end clarity, directly supporting audio quality goals.
• Compact radial can footprint: Small dimensions (L: 1.6 × D: 1 cm) and 5 mm lead spacing simplify placement in dense PCB assemblies.
• Measured ripple capability: Defined ripple ratings at 120 Hz (260 mA) and 10 kHz (390 mA) help designers select the part for known power conditions.
• Wide operating range and proven endurance: Rated for -40 °C to 85 °C and 1000 hours at 85 °C, providing predictable behavior across typical audio equipment environments.
• Regulatory compliance: RoHS conformity supports use in designs requiring restricted‑substance compliance.
