UFW1V332MHD

The UFW1V332MHD from Nichicon is a radial-lead aluminum electrolytic capacitor in the UFW series designed for audio equipment and related power filtering tasks. It provides 3.3 mF (3300 µF) capacitance at a 35 V rating with polarized radial-can packaging optimized for PCB power rails and audio circuits.

This part combines high capacitance density, rated ripple handling at both low and high frequencies, and a 2000-hour endurance at 85°C, making it suitable for production runs and OEM audio designs that require stable smoothing and decoupling performance.

Key Features

• High Capacitance: 3.3 mF (3300 µF) nominal capacitance with ±20% tolerance for bulk energy storage and smoothing in power supplies and audio circuits.
• 35 V Rated Voltage: Rated at 35 V to support mid-voltage audio amplifiers and power-supply sections.
• Ripple Current Performance: Low-frequency ripple current of 2.220 A (120 Hz) and high-frequency ripple current of 2.553 A (10 kHz) to handle dynamic audio loads and switching ripple.
• Loss and Leakage: Specified tangent of loss angle (tan δ) of 0.18 and leakage current of 3465 µA, providing predictable dissipation and leakage characteristics for circuit design.
• Mechanical Footprint: Compact radial can with φ16 × 35.5 mm body (size L: 3.55 × D: 1.6 cm) and 7.5 mm lead spacing for standard radial PCB mounting and through-hole assembly.
• Endurance and Temperature Range: 2000-hour lifetime at 85°C and an operating temperature range of −40°C to +85°C for stable long-term operation under elevated temperatures.
• Packaging and Availability: Supplied in bulk/bag packing and designated for mass production to support high-volume manufacturing.

Typical Applications

• Audio Equipment: Power-supply smoothing and decoupling in amplifiers, preamplifiers, and other audio systems where the UFW series is specified for audio use.
• Power Filtering for Signal Chains: Bulk energy storage and ripple suppression on audio-related power rails to reduce noise and maintain stable supply voltages.
• OEM Production Builds: Radial-can form factor and bulk packing tailored for assembly in consumer and professional audio product manufacturing.

Unique Advantages

• Large Energy Storage in a Compact Can: 3.3 mF capacitance in a φ16 × 35.5 mm package provides significant bulk capacity while minimizing board area.
• Dual-Frequency Ripple Capability: Specified ripple currents at both 120 Hz and 10 kHz support performance across low-frequency rectified supplies and higher-frequency switching environments.
• Designed for Audio Use: Part of Nichicon’s UFW series, specified for audio equipment, aligning electrical characteristics and form factor with audio system requirements.
• Manufacturing-Friendly Packaging: Bulk/bag packing and mass-production designation simplify procurement and high-volume assembly planning.
• Robust Thermal Endurance: 2000 hours at 85°C rating delivers predictable lifetime behavior under sustained elevated temperatures.
