UKL1E101KPD

The UKL1E101KPD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UKL low-leakage series. It provides 100 µF capacitance at a 25 V rating in a compact φ8 × 11.5 mm can with 3.5 mm lead spacing, optimized for through-hole board layouts.

Designed for audio equipment and other electronics where low leakage, controlled ripple handling and compact size matter, this part combines specified low leakage current, frequency-dependent ripple capability and a 2000-hour endurance at 85 °C.

Key Features

• Capacitance and Tolerance — 100 µF nominal with ±10% tolerance (120 Hz, 20 °C), providing predictable energy storage and decoupling.
• Rated Voltage — 25 V working voltage suitable for a range of low-voltage power rails.
• Low Leakage Current — Designed as part of Nichicon’s low leakage series; specified leakage current is 5 µA after rated voltage application.
• Ripple Current Performance — Rated ripple current: 280 mA at 120 Hz and 420 mA at 10 kHz, supporting both low- and high-frequency ripple filtering requirements.
• Reliability and Endurance — Endurance rating of 2000 hours at 85 °C under rated voltage, with shelf-life and stability characteristics defined by the UKL series specifications.
• Package and Mounting — Radial-lead aluminum can (φ8 × 11.5 mm) with 3.5 mm lead spacing and lead spacing tolerance ±0.5 mm; available in bulk (no terminal forming) or bag packing.
• Operating Temperature — Specified for −40 °C to +85 °C operation, suitable for typical ambient ranges encountered in consumer and professional audio equipment.
• RoHS Compliance — Product is RoHS compliant as specified in the series documentation.

Typical Applications

• Audio — Power supply smoothing: Provides bulk decoupling and smoothing on low-voltage audio power rails where low leakage and stable capacitance are important.
• Audio — Signal/bias stability: Supports circuit bias and coupling applications in audio circuitry where minimized leakage current preserves DC conditions.
• Audio — Power amplifier filtering: Used for ripple suppression and local energy storage in amplifier output and supply sections, leveraging its specified ripple current capability.

Unique Advantages

• Low-leakage design: The UKL series heritage and specified 5 µA leakage characterize this part for circuits that require minimal DC leakage and stable bias.
• Frequency-aware ripple handling: Explicit ripple current ratings at 120 Hz (280 mA) and 10 kHz (420 mA) make it easy to match to power-supply and amplifier ripple profiles.
• Compact radial can: φ8 × 11.5 mm footprint with 3.5 mm lead spacing supports space-constrained through-hole layouts.
• Engineered endurance: Rated 2000 hours at 85 °C under rated voltage for predictable life in sustained ambient conditions.
• RoHS compliant: Meets RoHS directive requirements as called out in the series documentation.
