UKL1H331MHD

The UKL1H331MHD is a 330 µF, 50 V miniature aluminum electrolytic capacitor in a radial lead can package from Nichicon's UKL series. Engineered for low leakage and compact power filtering, it targets audio-centric designs and other applications that require stable DC smoothing and ripple handling in a small form factor.

Key value propositions include low leakage current and a combination of low-frequency and high-frequency ripple capabilities, making it suitable where both DC stability and AC ripple performance matter within the specified operating conditions.

Key Features

• Capacitance & Voltage – 330 µF nominal capacitance rated at 50 V for moderate-voltage power rails.
• Low Leakage & Low Dissipation – Leakage current specified at 33 µA; tan δ (DF) = 0.1 measured at 20°C, 120 Hz, supporting stable DC performance.
• Ripple Handling – Low-frequency ripple current: 600 mA at 120 Hz; high-frequency ripple current: 900 mA at 10 kHz, enabling effective smoothing across a range of ripple profiles.
• Compact Radial Package – Case size φ12.5 × 20 mm with 5 mm lead spacing (±0.5 mm), radial lead mounting for through-hole assemblies.
• Reliability & Endurance – Life rating of 2000 hours at 85°C, supporting sustained operation at elevated temperatures within the rated range.
• Operating Range & Polarity – Polarized capacitor specified for operation from −40°C to +85°C.
• Packaging Options – Available in Bulk (no terminal forming) or bag packing for flexible procurement and assembly handling.
• Environmental Compliance – RoHS compliant.

Typical Applications

• Audio Amplifiers – DC smoothing and power-rail decoupling where low leakage and high ripple capability preserve audio performance.
• Portable Audio Equipment – Compact radial package provides bulk capacitance and ripple tolerance in space-constrained audio devices.
• Audio Power Supplies – Filtering and energy storage on moderate-voltage power rails, benefiting from the 2000-hour endurance at 85°C.

Unique Advantages

• Low Leakage Current: 33 µA leakage supports minimal DC loss and longer bias stability in sensitive circuits.
• Broad Ripple Performance: Rated ripple current of 600 mA (120 Hz) and 900 mA (10 kHz) covers both mains-frequency and higher-frequency switching noise scenarios.
• Small Footprint: φ12.5 × 20 mm can size into compact designs while delivering 330 µF capacitance at 50 V.
• Measured Dissipation Factor: tan δ = 0.1 at 20°C/120 Hz provides predictable loss characteristics for thermal and performance budgeting.
• Designed for Through-Hole Assembly: Radial lead construction with 5 mm lead spacing simplifies placement in traditional PCB layouts and prototyping.
• Regulatory Compliance: RoHS compliance supports environmental and regulatory requirements for many markets.
