UKL1H681MHD

The UKL1H681MHD is a radial-leaded aluminum electrolytic capacitor designed for low leakage current applications. With 680 µF capacitance at 50 V and a compact φ16 × 25 mm can, it targets circuits that require bulk energy storage and DC smoothing with minimized leakage.

Key use cases include audio equipment and other electronic systems where low-leakage performance, measurable ripple handling, and a through-hole radial package are required. The part is RoHS compliant and supplied in bulk or bag packing for service and production needs.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with ±20% tolerance, rated for 50 V operation.
• Low Leakage Current — Specified leakage current of 68 µA, minimizing standby loss and preserving charge over time.
• Ripple Current Capability — Handles 910 mA at low frequency (120 Hz) and 1.365 A at high frequency (10 kHz), supporting both low- and high-frequency ripple environments.
• Endurance & Temperature Range — Life rating of 2000 hours at 85 °C; operating temperature range of −40 °C to +85 °C.
• Radial Through-Hole Package — Can package sized φ16 × 25 mm with 7.5 mm lead spacing (±0.5 mm), ideal for standard radial mounting and repair/retrofit workflows.
• Polarized Design — Electrolytic, polarized capacitor suitable for DC smoothing and power rail decoupling.
• Regulatory Compliance & Packaging — RoHS compliant; available in Bulk (no terminal forming) or Bag packing.

Typical Applications

• Audio equipment — Bulk filtering and power-supply smoothing where low leakage helps maintain low noise and stable biasing for analog stages.
• Power supply decoupling — DC smoothing and energy reservoir for mid-voltage rails up to 50 V in consumer and industrial electronics.
• Maintenance and repair — Through-hole radial form factor and standard dimensions make it suitable for servicing legacy or in-field equipment that uses φ16 × 25 mm capacitors.

Unique Advantages

• Measured low leakage — 68 µA leakage current reduces quiescent current draw and supports circuits sensitive to leakage-induced drift.
• Dual-frequency ripple handling — Rated ripple currents at 120 Hz (910 mA) and 10 kHz (1.365 A) allow predictable performance across common power and switching frequencies.
• Compact radial can — φ16 × 25 mm size with 7.5 mm lead spacing provides a small footprint for through-hole designs and straightforward board replacement.
• Durability under load — 2000-hour endurance at 85 °C provides an established reliability metric for thermal-stressed applications.
• Regulatory convenience — RoHS compliance supports use in regions requiring hazardous-substance restrictions.
• Service-ready packaging — Available in Bulk or Bag packing for production runs or repair stock management.
