UKW0J682MHD

The UKW0J682MHD from Nichicon is a radial-lead aluminum electrolytic capacitor in the UKW series, designed for audio and AV equipment. It provides 6800 µF capacitance at 6.3 V with a ±20% tolerance in a compact φ12.5 × 25 mm can with 5 mm lead spacing.

Key electrical attributes include low-frequency ripple handling (1.6 A at 120 Hz), high-frequency ripple handling (1.84 A at 10 kHz), a rated operating temperature range of −40 °C to +85 °C, and a 2000-hour endurance at 85 °C. Note: this part is listed as End Of Life.

Key Features

• Audio-focused electrolyte formulation — Series-level design emphasizes a balanced sound profile suited for AV and audio equipment.
• High capacitance, low-voltage rating — 6.8 mF (6800 µF) at 6.3 V provides bulk energy storage for decoupling and power supply smoothing in low-voltage audio rails.
• Ripple current capability — Rated for 1.6 A at 120 Hz and 1.84 A at 10 kHz, supporting both low-frequency and higher-frequency ripple conditions.
• Endurance and temperature range — 2000 hours at 85 °C endurance and an operating range of −40 °C to +85 °C for reliable performance across typical AV environments.
• Compact radial can package — φ12.5 × 25 mm size with 5 mm lead spacing and radial leads for through-hole mounting and straightforward PCB placement.
• Leakage current specification — Product data lists leakage current at 1285.2 µA, useful for assessing standby and bias currents in designs.
• RoHS compliant and clear marking — Conforms to RoHS; parts are printed with gold lettering on a black sleeve for easy identification.
• Packaging options — Available bulk (no terminal forming) or bag packing to suit assembly and prototyping workflows.

Typical Applications

• Audio equipment — Bulk decoupling and smoothing in preamplifiers, power amplifiers, and AV components where sound quality and stable low-voltage supply filtering are important.
• Power supply filtering — Energy reservoir and ripple suppression on low-voltage rails to improve regulator stability and transient response.
• Consumer AV electronics — Compact through-hole solution for repair, retrofit, and board-level designs in consumer audio and AV devices.

Unique Advantages

• Audio-optimized electrolyte: Series-level formulation aimed at a harmonious balance of sound quality, directly addressing AV and audio design priorities.
• Dual-frequency ripple handling: Specified ripple current at both 120 Hz and 10 kHz supports performance across transformer-rectified supplies and higher-frequency switching environments.
• Compact footprint with through-hole ease: φ12.5 × 25 mm can and 5 mm lead spacing provide a small, serviceable package for PCB layouts and replacements.
• Long endurance at rated temperature: 2000-hour rating at 85 °C gives a defined life expectation for thermal-stressed applications.
• Clear identification and RoHS compliance: Gold-on-black sleeve marking aids part verification; RoHS compliance supports regulatory alignment.
