UFW2A331MHD

The UFW2A331MHD is an aluminum electrolytic capacitor from Nichicon’s UFW series, supplied in a radial lead can package. It provides 330 µF capacitance at a 100 V rating and is targeted for audio equipment applications.

Designed for engineers needing a compact, polarized capacitor with defined ripple and endurance characteristics, this part combines a small φ12.5×25 mm footprint with a rated operating range of -40 °C to 85 °C and 2000 hours endurance at 85 °C.

Key Features

• Capacitance & Voltage: 330 µF capacitance with a 100 V rated voltage, suitable where higher DC voltage handling is required.
• Audio-focused Series: Part of the UFW series specified for audio equipment, offering parameters tailored to audio applications.
• Ripple Current Capability: Low-frequency ripple current of 750 mA at 120 Hz and high-frequency ripple current of 1.125 A at 10 kHz, supporting a range of ripple conditions.
• Leakage & Tolerance: Specified leakage current of 990 µA and capacitance tolerance of ±20% (measured at 120 Hz, 20 °C).
• Temperature & Endurance: Operating temperature range from -40 °C to 85 °C with endurance specification of 2000 hours at 85 °C.
• Radial Lead Mechanical Details: φ12.5×25 mm can size with 5.0 mm lead spacing (±0.5 mm) and radial lead mounting.

Typical Applications

• Audio equipment: Intended for use in audio systems within the UFW series scope, where 330 µF/100 V capacitance and specified ripple characteristics are required.
• Audio electronics design: Suited to circuits in audio devices that benefit from a polarized electrolytic capacitor with defined endurance and temperature range.
• Equipment requiring compact radial cans: Applications that need a small-diameter radial-lead capacitor with 5 mm lead spacing and a φ12.5×25 mm package footprint.

Unique Advantages

• High voltage capability: 100 V rating enables use on higher-voltage audio rails compared with lower-voltage electrolytics.
• Defined ripple performance: Published ripple current ratings at 120 Hz and 10 kHz provide clear guidance for thermal and ripple handling in design.
• Temperature and longevity: Rated for -40 °C to 85 °C and 2000 hours endurance at 85 °C, supporting reliable operation in constrained thermal environments.
• Compact radial can form factor: φ12.5×25 mm size with 5 mm lead spacing allows space-efficient mounting in through‑hole layouts.
• Audio-series pedigree: Supplied as part of Nichicon’s UFW series for audio equipment, offering series-level specification alignment for audio designers.
• Production availability: Listed as mass production status, suitable for volume procurement.
