UKL2A471KHD

The UKL2A471KHD is a low-leakage aluminum electrolytic capacitor in a radial-can package, offering 470 µF capacitance at a 100 V rating with ±10% tolerance. Designed for audio applications, it provides bulk energy storage and stable performance across a −40 °C to 85 °C operating range.

Its combination of low leakage current, defined ripple capability at multiple frequencies, and a compact φ18 × 35.5 mm can make it suitable for engineers specifying power filtering and smoothing components in audio equipment.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with ±10% tolerance and a 100 V rated voltage for higher-voltage audio power rails.
• Low Leakage Current — Specified leakage current of 94 µA, helping to minimize standby losses and preserve bias conditions.
• Ripple Current Capability — Low-frequency ripple current of 910 mA at 120 Hz and high-frequency ripple current of 1.365 A at 10 kHz for effective filtering across audio-relevant frequencies.
• Endurance & Temperature — Rated lifetime of 2000 hours at 85 °C with an operating temperature range from −40 °C to 85 °C.
• Package & Mounting — Radial lead, can-style package with φ18 × 35.5 mm dimensions, 7.5 mm lead spacing (±0.5 mm), and bulk/bag packing options.
• Environmental Compliance — RoHS compliant.

Typical Applications

• Audio Equipment — For power filtering and reservoir capacitance in audio amplifiers and associated power supplies where low leakage is important.
• Audio Power Modules — Supports ripple currents up to 910 mA (120 Hz) and 1.365 A (10 kHz) for smoothing and decoupling on audio power rails.
• Audio Signal Systems — 470 µF, ±10% capacitance provides bulk energy storage for stable supply performance in audio subsystems.

Unique Advantages

• Low Standby Losses: The low leakage current (94 µA) helps maintain bias and reduce power draw during idle conditions.
• High-Voltage Capability: 100 V rating supports higher-voltage audio power rails and designs requiring greater voltage headroom.
• Frequency-Dependent Ripple Performance: Defined ripple current ratings at 120 Hz and 10 kHz support filtering needs across low and high audio frequencies.
• Compact Radial Can: φ18 × 35.5 mm package with 7.5 mm lead spacing simplifies through-hole placement and mechanical mounting in audio PCBs.
• Engineered for Elevated Temperatures: 2000-hour endurance at 85 °C delivers predictable performance in thermally active enclosures.
• RoHS Compliant: Meets environmental directive requirements for lead-free assemblies.
