UKL2A471MHD

The UKL2A471MHD from Nichicon is a radial-lead aluminum electrolytic capacitor in the UKL low-leakage series, offering 470 µF capacitance at a 100 V rating. It combines low leakage characteristics with robust ripple-handling and a compact radial can package (φ18 × 35.5 mm) aimed at audio-oriented designs and related electronic equipment.

Designed for through‑hole implementations, this polarized capacitor delivers specified low-frequency and high-frequency ripple current performance and a rated endurance of 2000 hours at 85°C, providing predictable behavior across its −40°C to +85°C operating range.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with a 100 V rated voltage and ±20% tolerance, suitable for high-voltage filtering and energy storage in applicable circuits.
• Low Leakage Performance — Part of Nichicon’s UKL low leakage current series; the part’s listed leakage current is 94 µA, supporting circuits where minimizing standby loss and DC bias drift is important.
• Ripple Current Capability — Rated low-frequency ripple current of 910 mA (120 Hz) and high-frequency ripple current of 1.365 A (10 kHz), enabling reliable smoothing under both line-frequency and higher-frequency ripple conditions.
• Endurance & Temperature Range — 2000 hours life at 85°C and an operating temperature range of −40°C to +85°C, allowing predictable long-term performance in moderate-temperature environments.
• Mechanical & Mounting — Radial lead, polarized can with dimensions φ18 × 35.5 mm and 7.5 mm lead spacing (±0.5 mm), compatible with through-hole PCB layouts and replacement applications requiring this form factor.
• Compliance & Packaging — RoHS compliant; available in bulk (no terminal forming) or bag packing to match assembly and repair workflows.

Typical Applications

• Audio equipment power filtering — Provides bulk capacitance and smoothing in audio power supplies where a 100 V rating and 470 µF value are required.
• Audio amplifier circuits — Low leakage characteristic supports DC bias stability and minimizes unwanted current paths in amplifier and preamplifier stages.
• Repair and legacy board replacement — Radial-lead can (φ18 × 35.5 mm) and 7.5 mm lead spacing make this part suitable for servicing and refurbishing equipment designed around similar through-hole capacitors.

Unique Advantages

• Low standby loss: The UKL series’ low leakage behavior (94 µA listed) helps preserve DC conditions and reduces power loss during idle periods.
• Dual-frequency ripple handling: Specified ripple ratings at 120 Hz and 10 kHz (910 mA and 1.365 A) give designers clear guidance for both line-frequency and higher-frequency smoothing needs.
• High-voltage capability: 100 V rating provides headroom for designs requiring elevated DC voltages without up-rating multiple lower-voltage capacitors.
• Compact radial form: φ18 × 35.5 mm can and 7.5 mm lead spacing offer a compact through-hole footprint for power and audio PCBs.
• Predictable lifetime: 2000 hours at 85°C specification supports reliability planning and lifecycle considerations for moderate-temperature applications.
• RoHS compliant packaging options: Bulk or bag packing choices simplify procurement for both manufacturing and repair environments while meeting RoHS requirements.
