UKL1C472KHD

The UKL1C472KHD is a radial lead aluminum electrolytic capacitor designed for low leakage current applications. With 4700 µF capacitance at 16 V, it delivers high ripple handling and stable performance across a wide temperature range for audio and other low-voltage electronic systems.

This part offers a compact φ18 × 35.5 mm can with 7.5 mm lead spacing, specified lifetime of 2000 hours at 85°C, and RoHS compliance. Note: this product is End Of Life and is scheduled to be discontinued; it is not recommended for new designs.

Key Features

• Capacitance and Voltage — 4700 µF nominal capacitance with ±10% tolerance at a rated voltage of 16 V, suitable for bulk energy storage and filtering in low-voltage circuits.
• Low Leakage Current — Specified leakage current of 150.4 µA, supporting applications where minimized standby or bias leakage is important.
• High Ripple Current Capability — Low-frequency ripple current of 1.82 A (120 Hz) and high-frequency ripple current of 2.093 A (10 kHz), enabling reliable AC ripple handling in power and audio circuits.
• Temperature and Endurance — Rated for operation from −40°C to +85°C with an endurance of 2000 hours at 85°C.
• Package and Mounting — Radial lead, can-style package (φ18 × 35.5 mm) with 7.5 mm lead spacing and 0.8 mm lead diameter; available in bulk (no terminal forming) or bag packing.
• Polarized Design — Polar capacitor suitable for typical DC filtering and smoothing tasks where polarity is observed.
• Environmental Compliance — RoHS compliant.

Typical Applications

• Audio systems — Bulk filtering, power supply decoupling, and smoothing in audio amplifiers and consumer audio equipment where low leakage and reliable ripple handling matter.

Unique Advantages

• Low standby leakage: 150.4 µA leakage current reduces bias loss and helps maintain signal integrity in sensitive circuits.
• Robust ripple handling: 1.82 A (120 Hz) and 2.093 A (10 kHz) ripple ratings support both low- and high-frequency ripple conditions common in audio power supplies.
• Compact radial form factor: φ18 × 35.5 mm can with 7.5 mm lead spacing offers a space-efficient solution for through-hole assemblies.
• Engineered for elevated temperatures: 2000-hour endurance at 85°C delivers predictable lifetime performance under sustained thermal stress.
• Regulatory compliance: RoHS status simplifies environmental compliance for assemblies and end products.

Why Choose UKL1C472KHD?

UKL1C472KHD combines high capacitance (4700 µF) with controlled leakage and strong ripple-current capability in a compact radial package, making it well suited for audio power supply smoothing and related low-voltage applications that require stable performance up to 85°C. Its defined endurance and RoHS compliance make it an appropriate choice for maintenance, repair, or replacement scenarios where the original form factor and electrical characteristics must be matched.

Because this part is End Of Life and scheduled for discontinuation, it is particularly relevant for legacy-equipment service and supply continuity rather than new designs.
