UKL1H101KPD

The UKL1H101KPD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon's UKL series designed for low-leakage, general-purpose power and audio applications. With a 100 µF capacitance at 50 V rating and compact φ10 × 16 mm dimensions, it delivers reliable filtering and decoupling in space-constrained assemblies.

Engineered for stability across a –40°C to 85°C operating range and an endurance rating of 2000 hours at 85°C, this capacitor is a practical choice where low leakage, measurable tanδ, and defined ripple handling are required.

Key Features

• Capacitance and Tolerance — 100 µF nominal capacitance with a tolerance of −10% to +10% (K), suitable for bulk decoupling and smoothing tasks.
• Rated Voltage — 50 V working voltage for mid-voltage power rails and audio supply lines.
• Low Leakage — Specified leakage current of 10 µA; the UKL series is characterized as a low-leakage lineup in the datasheet.
• Loss Angle (tanδ) — tanδ of 0.1 measured at 20°C, 120 Hz, enabling predictable ESR-related behavior for audio and analog circuits.
• Ripple Current Capability — Rated low-frequency ripple current of 320 mA at 120 Hz and a high-frequency ripple current of 480 mA at 10 kHz, providing defined ripple performance across common power-supply frequencies.
• Endurance and Temperature Range — 2000 hours life at 85°C and operating range from −40°C to +85°C for durability in typical commercial environments.
• Package and Mounting — Radial lead, can-style package sized φ10 × 16 mm with 5.0 mm lead spacing (±0.5 mm tolerance); available in bulk or bag packing.
• Regulatory — Compliant with RoHS (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio Electronics — Power-supply smoothing and decoupling in amplifiers, preamps, and audio peripherals where low leakage and stable loss characteristics benefit signal fidelity.
• Power Supply Filtering — Bulk decoupling and ripple suppression on mid-voltage rails in consumer and industrial equipment.
• Analog and Sensor Circuits — Local supply stabilization for analog front-ends and sensor interfaces that require predictable leakage and ESR behavior.
• Compact Consumer Devices — Space-constrained modules that need a small φ10 × 16 mm radial electrolytic for board-level power conditioning.

Unique Advantages

• Compact, high-voltage capability: 50 V rating in a φ10 × 16 mm package offers a balance of voltage handling and small form factor for tight layouts.
• Verified low leakage: Specified leakage of 10 µA and inclusion in Nichicon’s low-leakage UKL series reduce standby losses and bias drain in sensitive circuits.
• Defined ripple handling across frequencies: Separate low-frequency and high-frequency ripple current ratings (320 mA at 120 Hz, 480 mA at 10 kHz) make performance predictable for both line-frequency and switching environments.
• Long endurance at elevated temperature: 2000 hours at 85°C provides a clear measure of long-term stability for designs with sustained thermal stress.
• RoHS compliance: Meets RoHS requirements for use in regulated consumer and commercial products.
