UKL1H331KHD

The UKL1H331KHD from Nichicon is a radial-lead aluminum electrolytic capacitor in the UKL low-leakage series. It provides 330 µF capacitance at a 50 V rating in a compact φ12.5 × 20 mm can with 5 mm lead spacing.

Engineered for audio applications, this polarized capacitor combines low leakage (33 µA), rated ripple-handling (600 mA at 120 Hz / 900 mA at 10 kHz) and a rated endurance of 2000 hours at 85°C, offering a balance of stability and compact form factor for board-level power and signal designs.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with ±10% tolerance, rated for 50 V operation.
• Low Leakage — Leakage current specified at 33 µA for reduced bias loss and improved long-term stability in DC circuits.
• Ripple Current Performance — Low-frequency ripple current 600 mA (120 Hz) and high-frequency ripple current 900 mA (10 kHz) to support a range of power-frequency conditions.
• Endurance & Temperature Range — Rated life of 2000 hours at 85°C and operating temperature range from −40°C to +85°C.
• Package & Mounting — Radial lead, can-style package sized φ12.5 × 20 mm with 5 mm lead spacing; supplied in bulk/no terminal forming or bag packing.
• Polarized Electrolytic — Polarized construction suitable for DC circuits where polarity is observed.
• Environmental Compliance — RoHS-compliant.

Typical Applications

• Audio — Specified for audio equipment applications where low leakage and stable ripple handling are required.

Unique Advantages

• Low leakage for bias stability: 33 µA leakage current reduces DC drift and helps maintain bias in audio and signal circuits.
• Broad ripple capability: Rated ripple currents of 600 mA (120 Hz) and 900 mA (10 kHz) address both low- and high-frequency power demands.
• Compact radial can: φ12.5 × 20 mm package with 5 mm lead spacing provides a small footprint for board-level mounting while retaining robust capacitance.
• Designed for extended operation: 2000 hours at 85°C endurance rating supports durability in thermally stressed environments.
• Polarized design for DC circuits: Suitable where a polarized electrolytic is required to meet circuit topology and voltage requirements.
• RoHS-compliant: Meets environmental directive requirements for lead-free production lines.
