UHW1H331MPD

The UHW1H331MPD is a miniature, high-reliability aluminum electrolytic capacitor in a radial lead can designed for general-purpose power electronics. It delivers 330 µF at 50 V in a compact φ10 × 20 mm package with 5 mm lead spacing, combining high ripple handling and low impedance for robust power filtering and decoupling.

Built for demanding thermal and ripple environments, this UHW-series capacitor offers a long endurance rating and broad operating temperature range, making it suitable for compact assemblies where sustained performance and lifetime are important.

Key Features

• Capacitance & Voltage — 330 µF rated capacitance with a 50 V working voltage and a tolerance of −20% to +20% for predictable energy storage in power circuits.
• Low Impedance — Rated impedance of 90 mΩ, supporting improved transient response and reduced voltage ripple at the capacitor terminals.
• High Ripple Current Capability — Low-frequency ripple current of 1.03 A at 120 Hz and high-frequency ripple current of 2.06 A at 10 kHz, enabling reliable performance under AC ripple loading.
• Low Dissipation Factor — tanδ of 0.1 (measured at 20°C, 120 Hz), indicating efficient performance with reduced dielectric losses.
• Long Endurance — Rated for 10,000 hours at 105°C, providing extended service life in high-temperature applications when used within rated conditions.
• Wide Temperature Range — Operates from −40°C to +105°C to accommodate a variety of environmental conditions.
• Compact Radial Lead Package — φ10 × 20 mm can with 5 mm lead spacing (±0.5 mm) for through-hole assemblies requiring small footprint and straightforward mounting.
• Low Leakage — Specified leakage current of 165 µA, suitable for circuits where leakage control is required after two minutes at rated voltage.
• RoHS Compliant & Packaging — Lead-free (RoHS) construction with bulk or bag packing options for flexible procurement and assembly workflows.

Typical Applications

• Power supply filtering — Smooths DC bus and reduces output ripple where sustained ripple current handling and low impedance are required.
• DC‑DC converter input/output — Provides bulk decoupling and energy buffering for converters operating up to 50 V.
• Industrial control electronics — Supports controllers and power modules that need reliable capacitance across −40°C to +105°C and extended endurance.
• Consumer and commercial power modules — Compact radial can format fits tight assemblies while delivering high ripple capability and low loss.

Unique Advantages

• Miniature footprint with high energy density — 330 µF in a φ10 × 20 mm can saves board area while maintaining meaningful capacitance.
• High ripple tolerance across frequencies — Specified ripple currents at 120 Hz and 10 kHz (1.03 A and 2.06 A) enable use in both low- and high-frequency power designs.
• Long high-temperature endurance — 10,000 hours at 105°C provides design confidence for sustained thermal stress.
• Low impedance and low tanδ — 90 mΩ impedance and tanδ of 0.1 reduce losses and improve voltage stability under load.
• Through-hole radial lead convenience — Standard lead spacing and robust can construction simplify prototyping and repair in field-serviceable hardware.
• Regulatory compliance — RoHS-compliant construction supports modern assembly and end-product requirements.
