UKL2A470KPD

The UKL2A470KPD is an aluminum electrolytic capacitor from Nichicon's UKL low-leakage series. It delivers 47 µF capacitance at a 100 V rating in a radial-lead can (φ10 × 20 mm) with ±10% tolerance, intended for applications requiring low leakage and elevated voltage handling.

Key attributes include low leakage current (9.4 µA), defined ripple current capability (220 mA at 120 Hz, 440 mA at 10 kHz), an operating range of −40℃ to 85℃ and a rated endurance of 2000 hours at 85℃. Status: End Of Life; products in this series are scheduled to be discontinued and are not recommended for new designs.

Key Features

• Electrical Performance  47 µF nominal capacitance with ±10% tolerance and a 100 V rated voltage for high-voltage smoothing and decoupling tasks.
• Low Leakage Current  Specified leakage current of 9.4 µA, part of Nichicon’s standard low leakage UKL series.
• Ripple Current Capability  Low-frequency ripple current 220 mA at 120 Hz and high-frequency ripple current 440 mA at 10 kHz, enabling performance across audio and power frequency ranges.
• Reliability & Endurance  Rated for 2000 hours of operation at 85℃ with an operating temperature range of −40℃ to 85℃.
• Radial Can Package  φ10 × 20 mm can with 5 mm lead spacing (±0.5 mm) and radial lead mounting for through-hole assembly.
• Compliance & Packing  RoHS compliant; available in Bulk (No Terminal Forming) or Bag Packing.

Typical Applications

• Audio  Designed for audio applications where low leakage and defined ripple handling support power filtering and decoupling tasks.

Unique Advantages

• Low leakage performance: The specified 9.4 µA leakage supports applications that require minimal DC loss and stable bias conditions.
• High-voltage rating: 100 V rating provides margin for higher-voltage audio and power circuits that need robust DC blocking or smoothing.
• Defined ripple capability: Rated ripple currents at both low and high frequencies (220 mA at 120 Hz, 440 mA at 10 kHz) enable predictable thermal and electrical behavior across frequency ranges.
• Compact radial form factor: φ10 × 20 mm can with 5 mm lead spacing offers a compact through-hole option for board-level placement.
• Proven endurance: 2000 hours at 85℃ provides a measurable reliability target for designs operating in elevated temperature environments.
• RoHS compliant packaging choices: RoHS compliance and Bulk/Bag packing provide flexible procurement and assembly options.

Why Choose UKL2A470KPD?

UKL2A470KPD is positioned for designs that require a compact, radial-lead aluminum electrolytic capacitor with low leakage, a 100 V rating, and defined ripple current characteristics—particularly in audio-related equipment. Its 47 µF capacitance, 9.4 µA leakage, and 2000-hour endurance at 85℃ make it suitable for established designs that depend on predictable electrical and thermal performance.

Note the product status: End Of Life. The capacitor remains a clear specification match where existing bill-of-materials or legacy designs require this exact combination of size, voltage, leakage, and ripple capability.
