UKT1H682MRD

The UKT1H682MRD from Nichicon is a radial-lead aluminum electrolytic capacitor in the UKT series designed for audio and general electronic equipment requiring large capacitance and wide temperature tolerance. This polarized can-style capacitor delivers 6.8 mF at 50 V with high ripple-current capability and a wide operating temperature range, providing bulk energy storage and smoothing in demanding environments.

Key Features

• High Capacitance — 6.8 mF (6800 µF) nominal capacitance for substantial energy storage and supply smoothing in power and audio circuits.
• 50 V Rated Voltage — Rated for 50 V operation to support higher-voltage rails and provide design margin where needed.
• Wide Temperature Range — Specified for operation from −55°C to +105°C, suitable for applications with broad ambient variations.
• Robust Endurance — 1000 h lifetime at 105°C, with capacitance change and loss-angle (tan δ) limits defined by endurance testing.
• High Ripple Current Capability — 2500 mA at 120 Hz (low frequency) and 2875 mA at 10 kHz (high frequency) to manage AC stress and reduce heating under ripple conditions.
• Loss and Leakage Characteristics — Specified tan δ of 0.24 at 20°C, 120 Hz, and a leakage current of 10200 µA as provided for this part.
• Radial Lead, Can Package — φ22 × 50 mm case with 10 mm lead spacing for through-hole mounting and straightforward assembly; bulk packaging with no terminal forming.
• AEC-Q200 Rated — Listed with AEC-Q200 in the product specifications, indicating component-level qualification per that rating.

Typical Applications

• Audio Equipment — Bulk filtering, power supply smoothing, and energy storage in general audio electronics where large capacitance and wide temperature tolerance are required.
• Power Supply Filtering — DC link smoothing and reservoir capacitance on 50 V rails to reduce ripple and stabilize supply rails.
• Industrial Electronics — Use in systems operating across wide temperature ranges that require durable electrolytic capacitance and high ripple handling.

Unique Advantages

• Substantial Energy Storage: 6.8 mF provides significant bulk capacitance to support load transients and long-duration filtering.
• Designed for High Ripple: High specified ripple currents at both low and high frequencies reduce thermal stress during AC loading.
• Wide Operating Range: −55°C to +105°C rating extends applicability across harsh ambient conditions.
• Endurance-Proven: 1000 hours at 105°C endurance rating gives a measurable baseline for lifetime and reliability planning.
• Through-Hole Ruggedness: Radial-lead can package with 10 mm lead spacing simplifies mounting and mechanical retention for rugged assemblies.
• AEC-Q200 Inclusion: Presence of the AEC-Q200 rating in specifications supports use in designs that require that level of component qualification.
