UKL1A682KHD

The UKL1A682KHD is a miniature aluminum electrolytic capacitor from Nichicon’s UKL series, designed as a standard radial-lead can for low-voltage, high-capacitance applications. It delivers 6800 µF capacitance at a 10 V rating in a compact φ18 × 35.5 mm package with 7.5 mm lead spacing.

Targeted for audio and low-voltage power applications, this polarized capacitor offers low leakage characteristics, defined ripple-current capability at both low and high frequencies, and an endurance rating for sustained operation up to 85°C.

Key Features

• Capacitance & Voltage — 6800 µF (6.8 mF) nominal capacitance at a 10 V rated voltage with a tolerance of −10% to +10%.
• Low Leakage Current — Specified leakage current of 136 µA and categorized within the UKL low-leakage series to minimize standby loss and drift.
• Ripple Current Handling — Low-frequency ripple current of 1.89 A at 120 Hz and high-frequency ripple current of 2.174 A at 10 kHz, supporting effective smoothing and decoupling across a range of frequencies.
• Endurance & Temperature — Rated for 2000 hours at 85°C with an operating temperature range of −40°C to +85°C, supporting sustained operation in elevated ambient conditions.
• Compact Radial Can — φ18 × 35.5 mm can with 7.5 mm lead spacing (±0.5 mm tolerance) and radial lead mounting for straightforward through-hole PCB integration.
• Polarized Design — Intended for polarized circuits; ensure correct orientation during assembly.
• RoHS Compliant — Meets RoHS requirements for restricted substances.
• Packaging Options — Supplied in bulk (no terminal forming) or bag packing for flexible assembly workflows.

Typical Applications

• Audio electronics — Bulk filtering and power supply smoothing in audio amplifiers and consumer audio devices where high capacitance and low leakage are required.
• Low-voltage power supplies — Energy storage and ripple suppression in 10 V class power rails and regulation stages.
• Decoupling and smoothing — Board-level decoupling for low-frequency and high-frequency ripple, supported by specified ripple-current ratings at 120 Hz and 10 kHz.

Unique Advantages

• High capacitance in a small footprint — 6800 µF at 10 V provides significant bulk capacitance while occupying a compact φ18 × 35.5 mm radial-can package.
• Defined low-leakage performance — A specified leakage current of 136 µA supports designs that benefit from reduced quiescent losses and stable long-term behavior.
• Dual-frequency ripple capability — Rated ripple currents at 120 Hz (1.89 A) and 10 kHz (2.174 A) give designers measurable performance for both low- and high-frequency filtering tasks.
• Endurance at elevated temperature — 2000-hour endurance at 85°C ensures predictable capacitance and dissipation-factor behavior over time under thermal stress.
• Through-hole reliability and ease of assembly — Radial-lead can and standard 7.5 mm lead spacing simplify placement and soldering in through-hole PCB assemblies.
