UKL1A682MHD

The UKL1A682MHD is a radial-lead aluminum electrolytic capacitor offering 6800 µF capacitance at a 10 V rating, designed for low leakage current performance within the Nichicon UKL series. It combines high capacitance in a compact can (φ18 × 35.5 mm) with radial through-hole mounting for straightforward integration in legacy and service applications.

Targeted primarily at audio applications, the device delivers high ripple-handling capability, a long 2000-hour endurance at 85°C, and RoHS compliance — making it suitable where stable bulk capacitance, low self-discharge, and reliable power smoothing are required.

Key Features

• Capacitance & Voltage — 6800 µF nominal capacitance at a 10 V rated voltage with ±20% tolerance, providing substantial bulk energy storage for low-voltage power rails.
• Low Leakage Current — Specified leakage current of 136 µA, aligned with the UKL series’ low-leakage characteristics for reduced self-discharge in standby and low-current circuits.
• High Ripple Current — Rated ripple current of 1.89 A at 120 Hz (low frequency) and 2.174 A at 10 kHz (high frequency), supporting power-supply smoothing and decoupling under AC ripple conditions.
• Endurance & Temperature — 2000 hours endurance at 85°C and an operating temperature range of −40°C to +85°C, suitable for sustained operation in moderate-temperature environments.
• Mechanical & Mounting — Radial lead (through-hole) can, size φ18 × 35.5 mm, lead spacing 7.5 mm, and polarized construction for ease of PCB mounting and reliable polarity-aware installation.
• Packaging — Available in bulk (no terminal forming) and bag packing options to accommodate production and service stocking needs.
• Compliance — RoHS compliant as part of Nichicon’s UKL series.
• Product Status — End Of Life. Please confirm availability and lead times when requesting supply information.

Typical Applications

• Audio power supply smoothing — Bulk energy storage for analog and digital audio power rails to reduce ripple and maintain stable supply under dynamic loads.
• Audio amplifier decoupling — Local bulk decoupling in amplifier stages where high capacitance and low leakage help preserve signal fidelity and bias stability.
• Service and repair of audio equipment — Through-hole form factor and series characteristics make this part suitable for replacement in legacy audio products and maintenance inventories.

Unique Advantages

• Substantial bulk capacitance in a compact can — 6800 µF in a φ18 × 35.5 mm package minimizes board space while delivering large energy reserves for low-voltage systems.
• Low self-discharge — 136 µA leakage current supports long idle times and preserves stored charge in preservation and standby states.
• Robust ripple capability across frequencies — High ripple current ratings at both 120 Hz and 10 kHz provide effective smoothing for both mains-derived and high-frequency switching noise.
• Durability at elevated temperature — 2000-hour life at 85°C offers predictable aging characteristics for applications with sustained thermal exposure.
• Through-hole mounting simplicity — Radial lead configuration eases retrofit, repair, and assembly in through-hole PCBs common in audio equipment.
• RoHS compliance — Conforms to RoHS requirements for restricted substances.
