UKL0J682MHD

The UKL0J682MHD is a Nichicon aluminum electrolytic capacitor in a radial lead can offering 6800 µF capacitance at a 6.3 V rating. It is part of the UKL series designed for low leakage current and is intended for audio applications where high capacitance, stable ripple handling and polarity are required.

The part features a compact φ18 × 35.5 mm package with 7.5 mm lead spacing, RoHS compliance, and a rated operating temperature range of −40 °C to +85 °C with a specified lifetime of 2000 hours at 85 °C. Note: this product is marked End Of Life.

Key Features

• High Capacitance: 6.8 mF (6800 µF) nominal capacitance suitable for bulk energy storage and power-supply filtering in audio circuits.
• Rated Voltage: 6.3 V working voltage, polarized electrolytic construction for DC applications.
• Low Leakage Current: Part of Nichicon's UKL low leakage series; series specification defines leakage ≤ 0.002CV (µA) after initial application of rated voltage at 20 °C.
• Ripple Handling: Specified ripple current: 1.76 A at 120 Hz and 2.024 A at 10 kHz, supporting both low- and high-frequency filtering requirements.
• Package & Mounting: Radial lead can, dimensions φ18 × 35.5 mm, lead spacing 7.5 mm, supplied bulk (no terminal forming) in bag packing.
• Temperature & Lifetime: Operating range −40 °C to +85 °C with a rated endurance of 2000 hours at 85 °C.
• Tolerance & Polarity: Capacitance tolerance −20% to +20%; polarized device required to be installed with correct polarity.
• Environmental Compliance: RoHS compliant per product data.

Typical Applications

• Audio Equipment: Bulk decoupling and power-supply smoothing in amplifiers and audio front-ends where high capacitance and low leakage preserve signal fidelity.
• Power Supply Filtering: Energy storage and ripple suppression for low-voltage DC rails in consumer and professional audio electronics.
• General Electronics: Applications requiring radial-lead mounting and compact high-capacitance solutions for charge reservoir and decoupling tasks.

Unique Advantages

• Large Capacitance in a Compact Can: 6800 µF in a φ18 × 35.5 mm radial package provides substantial energy storage without requiring larger PCB area.
• Low Leakage Behavior: UKL series low leakage specification (≤ 0.002CV after initial application) helps maintain charge retention and performance in DC-biased circuits.
• Measured Ripple Capability: Ripple current ratings at both 120 Hz (1.76 A) and 10 kHz (2.024 A) enable effective filtering across common power and switching frequencies.
• Designed for Audio Use: Explicitly specified for audio applications, aligning electrical characteristics with requirements for power-supply decoupling in audio signal paths.
• Proven Endurance: 2000 hours at 85 °C endurance rating provides a defined operational lifetime for thermal-stressed deployments.
• Regulatory Compliance: RoHS status declared compliant, supporting designs with restricted-substance requirements.
