UKL1J101MPD

The UKL1J101MPD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UKL low leakage series. It delivers 100 µF capacitance at a 63 V rating in a compact φ10 × 20 mm can, designed for applications where low leakage and stable ripple performance are required.

Targeted for audio applications, this polarized capacitor combines low leakage characteristics, defined ripple handling at both low and high frequencies, and a specified endurance of 2000 hours at 85°C to support reliable performance in demanding operating environments.

Key Features

• Core Type — Aluminum Electrolytic, Polarized Radial-lead polarized capacitor offering 100 µF nominal capacitance with ±20% tolerance.
• Low Leakage Performance Part of Nichicon’s UKL standard low leakage current series; specified leakage current is 12.6 µA (measured per series test conditions at 20°C).
• Voltage & Capacitance Rated for 63 V with a 100 µF capacitance value, suitable for medium-voltage audio and related circuits.
• Ripple Current Capability Low frequency ripple handling of 330 mA at 120 Hz and high frequency ripple handling of 495 mA at 10 kHz, supporting both power-rail smoothing and higher-frequency decoupling needs.
• Temperature Range & Endurance Operating temperature range from −40°C to +85°C with an endurance rating of 2000 hours at 85°C.
• Compact Radial Package Can dimensions φ10 × 20 mm with 5 mm lead spacing (±0.5 mm tolerance); available in bulk (no terminal forming) or bag packing.
• Environmental Compliance RoHS compliant.

Typical Applications

• Audio power rails — 100 µF at 63 V and 330 mA ripple capability at 120 Hz support smoothing and decoupling on audio amplifier power supplies.
• High-frequency decoupling in audio circuits — 495 mA ripple handling at 10 kHz provides headroom for higher-frequency demands in audio electronics.
• Compact audio modules — φ10 × 20 mm radial package and 5 mm lead spacing suit space-constrained audio assemblies requiring low leakage.

Unique Advantages

• Low leakage for stable biasing: 12.6 µA specified leakage current helps maintain DC bias stability in sensitive audio circuits.
• Dual-frequency ripple specification: Explicit ripple ratings at 120 Hz and 10 kHz allow designers to assess performance across both low- and high-frequency regimes.
• Durability at rated temperature: 2000 hours endurance at 85°C supports long-term reliability in continuous-operation environments.
• Compact radial form factor: φ10 × 20 mm can with standard 5 mm lead spacing simplifies layout in tight PCB real estate.
• Regulatory compliance: RoHS compliance for reuse in designs requiring lead-free components.
