UHW1V332MHD

The UHW1V332MHD is a Nichicon UHW series miniature radial-lead aluminum electrolytic capacitor offering 3.3 mF (3300 µF) capacitance at a 35 V rating. It is part of the high-reliability UHW family designed for compact, high-ripple-current applications.

With a low impedance (33 mΩ), specified low- and high-frequency ripple handling, and a 10,000-hour endurance at 105°C, this polarized radial-lead capacitor is targeted for general-purpose power applications where small size, long life and robust ripple performance are required.

Key Features

• Capacitance & Voltage — 3300 µF (3.3 mF) nominal capacitance with a rated voltage of 35 V and capacitance tolerance of -20% to +20%.
• High ripple-current capability — Rated for 3.0 A low-frequency ripple at 120 Hz and 4.0 A high-frequency ripple at 10 kHz, enabling effective smoothing in dynamic power environments.
• Low impedance — Typical impedance of 33 mΩ supports lower voltage drop under load and improved filtering performance.
• Loss characteristics — Tangent of loss angle (tan δ) of 0.15 measured at 20°C, 120 Hz, with the datasheet guidance for large-capacitance adjustments.
• Long endurance and temperature range — Rated lifetime of 10,000 hours at 105°C and an operating temperature range of -40°C to +105°C for extended reliability in elevated-temperature applications.
• Compact radial-lead package — Can dimensions φ16 × 30.5 mm with 7.5 mm lead spacing (±0.5 mm), polarized radial-lead mounting for through-hole designs; available in bulk or bag packing.
• RoHS compliant — Meets RoHS directive requirements as indicated in the product data.

Typical Applications

• General-purpose power supplies — Bulk smoothing and decoupling where high ripple-current capability (3 A @ 120 Hz, 4 A @ 10 kHz) and low impedance are required.
• Power management modules — Local energy storage and transient suppression in compact assemblies benefitting from the capacitor’s miniature φ16 × 30.5 mm footprint.
• Industrial and embedded equipment — Long-endurance components for designs that require operation across -40°C to +105°C and 10,000 hours of rated life at elevated temperature.

Unique Advantages

• High ripple tolerance: The specified 3 A (120 Hz) and 4 A (10 kHz) ripple ratings allow designers to size fewer capacitors for the same ripple duty, simplifying BOM and layout.
• Compact, through-hole form factor: φ16 × 30.5 mm radial can with 7.5 mm lead spacing packs high capacitance into a small footprint for space-constrained PCBs.
• Proven endurance at elevated temperature: 10,000 hours at 105°C provides predictable lifetime performance for sustained thermal conditions.
• Low impedance for improved filtering: 33 mΩ impedance supports reduced ripple voltage and better load regulation in power circuits.
• Clear specification and handling: Polarized radial-lead package, available in bulk or bag packing, and mass-production status simplify procurement and assembly planning.
