UFW2A471MHD

The UFW2A471MHD is a Nichicon UFW series aluminum electrolytic capacitor in a radial-lead, can-style package designed for audio equipment. It provides 470 µF capacitance at a 100 V rating with a ±20% tolerance and is intended for applications requiring bulk energy storage and ripple handling in audio-focused power rails.

Key attributes include defined ripple current capability across low and high frequencies, a 2000-hour endurance at 85 °C, and a wide operating temperature range of −40 °C to +85 °C, making it suitable for production-level use in audio electronics assemblies.

Key Features

• Capacitance & Voltage: 470 µF nominal capacitance with a 100 V rated voltage and ±20% tolerance, specified at 120 Hz and 20 °C.
• Ripple Current Performance: Rated ripple current of 1.0 A at 120 Hz and 1.5 A at 10 kHz, with frequency coefficients applicable to 100–470 µF parts (for reference: 0.80 at 50 Hz, 1.00 at 120 Hz, 1.23 at 300 Hz, 1.34 at 1 kHz, 1.50 at 10 kHz or more).
• Leakage Current: Specified leakage current of 1410 µA for this part (measured conditions as defined by the series specifications).
• Reliability / Lifetime: Endurance rated for 2000 hours at 85 °C with capacitance change within ±20% and leakage current meeting initial-specified limits after the test.
• Temperature Range: Operates from −40 °C to +85 °C, matching the UFW series category temperature range.
• Package & Mounting: Radial lead, can package with dimensions φ16 × 25 mm and 7.5 mm lead spacing (φ16×25L); supplied in bulk/bag packaging for mass-production assembly.
• Audio-focused Series: Part of the Nichicon UFW series, specified as standard for audio equipment.

Typical Applications

• Audio equipment power rails: Bulk energy storage and smoothing for power supplies in audio systems.
• Amplifier modules: Power-supply decoupling and ripple filtering where higher voltage and defined ripple handling are required.
• Consumer and professional audio electronics: General-purpose filtering/decoupling in audio-focused assemblies built to standard production practices.

Unique Advantages

• High-voltage support: 100 V rating enables use on higher-voltage audio power rails and designs requiring elevated DC bias capacity.
• Defined ripple capability across frequency: Rated ripple currents at 120 Hz and 10 kHz with published frequency coefficients allow designers to size for both low- and high-frequency stress.
• Production-ready packaging: Supplied in bulk/bag and marked for mass production, easing procurement and assembly for volume builds.
• Robust thermal endurance: 2000 hours at 85 °C specified endurance delivers predictable aging and reliability data for design verification.
• Wide operating range: −40 °C to +85 °C operating temperature supports use across typical environmental conditions for audio electronics.
• Compact radial package: φ16 × 25 mm can with 7.5 mm lead spacing balances capacitance and footprint for through-hole designs.
