UKL1J470KPD

The UKL1J470KPD from Nichicon is a radial-lead aluminum electrolytic capacitor in the UKL series, specified for 47 µF capacitance at 63 V with ±10% tolerance. Its low leakage characteristic, defined ripple current ratings, and 2000-hour endurance at 85°C make it suitable for audio-oriented designs and other applications that require stable biasing and filtering in a compact radial can.

Key Features

• Capacitance & Voltage — 47 µF nominal capacitance with a rated voltage of 63 V and ±10% tolerance, specified at 120 Hz, 20°C.
• Low Leakage — Measured leakage current of 5.922 µA (after 1 minute at 20°C for the φ10×12.5 case), supporting stable long‑term bias conditions.
• Ripple Current Handling — Low-frequency ripple current rated 200 mA at 120 Hz and high-frequency ripple current rated 400 mA at 10 kHz, with frequency coefficients defined by the UKL series.
• Endurance & Temperature — Life rating of 2000 hours at 85°C and an operating temperature range of −40°C to +85°C.
• Package & Mounting — Radial lead, can-style package with dimensions φ10 × 12.5 mm and lead spacing 5.0 mm (±0.5 mm), suitable for radial-lead mounting layouts.
• Polarized — Polarized capacitor for proper DC bias applications.
• Compliance & Packing — RoHS compliant; available in bulk (no terminal forming) or bag packing.

Typical Applications

• Audio — Specified for audio applications where low leakage and defined ripple handling support stable filtering and bias circuits.

Unique Advantages

• Defined low leakage performance — A leakage current of 5.922 µA (φ10×12.5 case) provides predictable bias behavior in DC-coupled and precision circuits.
• Frequency-aware ripple ratings — Separate ripple specifications for 120 Hz and 10 kHz (200 mA and 400 mA respectively) help designers assess performance across low- and high-frequency filtering tasks.
• Compact radial can — φ10 × 12.5 mm size with 5 mm lead spacing delivers a small footprint for space-constrained radial-lead assemblies.
• Robust thermal endurance — 2000 hours at 85°C rating supports reliability expectations for sustained elevated-temperature operation within the specified range.
• RoHS compliance and flexible packing — Environmentally compliant construction and bulk or bag packing options ease procurement and assembly planning.
