UFW1C332MHD

The UFW1C332MHD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UFW series designed for audio equipment. It delivers high bulk capacitance in a compact φ12.5 × 25 mm can with a 5 mm lead spacing, optimized for power filtering and energy storage in audio applications.

Key strengths include substantial ripple-handling capability at both low and high frequencies, a measured dissipation factor at audio test conditions, and a 2000-hour endurance rating at 85°C—making it suitable for designs that require stable performance over time in the -40°C to 85°C operating range.

Key Features

• Capacitance & Rated Voltage — 3.3 mF (3300 µF) nominal capacitance at a rated voltage of 16 V with ±20% tolerance.
• Ripple Current Performance — Rated ripple current of 1.7 A at 120 Hz (low frequency) and 1.955 A at 10 kHz (high frequency), supporting effective ripple filtering across audio-band and higher-frequency switching noise.
• Dissipation Factor (tan δ) — Specified tan δ of 0.24 at 20°C and 120 Hz, useful for assessing loss behavior under audio-frequency testing conditions.
• Leakage Current — Measured leakage current of 1584 µA under rated conditions.
• Endurance & Stability — 2000 hours life at 85°C; after endurance testing and restoration to 20°C, capacitance change will remain within ±20%, tan δ within 200% of initial value, and leakage current at or below initial specified limits.
• Temperature Range — Operates from -40°C to +85°C to cover common audio equipment ambient conditions.
• Package & Mounting — Radial lead can (φ12.5 × 25 mm), 5 mm lead spacing, supplied in bulk (no terminal forming) or bag packing; suitable for through-hole mounting.
• Production Status — Mass production availability for design and volume supply.

Typical Applications

• Audio Equipment — Bulk energy storage and supply smoothing for audio power rails, leveraging 3300 µF capacitance and high ripple current ratings to support steady playback and amplifier performance.
• Power Supply Filtering in Consumer Audio — Removes low-frequency ripple and reduces higher-frequency switching components in audio-grade power supplies, supported by the part’s 120 Hz and 10 kHz ripple specifications.
• Signal Chain Support — Serves as a local reservoir for transient demands in audio preamplifiers and signal conditioning modules where stable supply voltage and endurance are important.

Unique Advantages

• High Bulk Capacitance in a Compact Can — 3300 µF in a φ12.5 × 25 mm package reduces board area while providing substantial energy storage for audio systems.
• Wide Ripple Frequency Coverage — Rated ripple current specified at both 120 Hz and 10 kHz enables designers to address power quality across audio and switching-frequency domains.
• Audio-Focused Performance Parameters — Dissipation factor provided at 20°C/120 Hz and series positioning “For Audio Equipment” align the part with audio-centric design requirements.
• Operational Endurance — 2000 hours at 85°C with defined post-test limits gives predictable long-term behavior for projects requiring lifecycle visibility.
• Through-Hole Simplicity — Radial lead mounting and standard 5 mm spacing simplify assembly and replacement in serviceable audio electronics.
