UKL1H680KPD

The UKL1H680KPD is a polarized aluminum electrolytic capacitor in a radial-lead can, delivering 68 µF capacitance with ±10% tolerance and a 50 V rating. It belongs to Nichicon's UKL low-leakage series and is intended for audio and other compact through-hole applications that require low leakage and reliable ripple handling.

Key electrical characteristics include low leakage current, defined ripple current ratings at both low and high frequencies, and a 2000 hour endurance at 85°C. Status: End Of Life — this unit is scheduled for discontinuation and is not recommended for new designs.

Key Features

• Capacitance & Tolerance — 68 µF nominal with ±10% tolerance (K) measured at 120 Hz, 20°C.
• Rated Voltage — 50 V DC nominal rating suitable for mid-voltage audio and general-purpose circuits.
• Low Leakage Current — Specified leakage current of 6.8 µA after rated-voltage application, supporting low-bias loss in standby conditions.
• Ripple Current Capability — 250 mA at 120 Hz (low frequency) and 500 mA at 10 kHz (high frequency) for effective smoothing and decoupling across audio bandwidths.
• Endurance & Temperature Range — Rated for 2000 hours at 85°C and an operating range of −40°C to +85°C.
• Package & Mounting — Radial-lead can, size φ10 × 12.5 mm, lead spacing 5 mm (±0.5 mm). Available in bulk (no terminal forming) and bag packing.
• RoHS Compliance — Compliant to applicable RoHS directives.

Typical Applications

• Audio Electronics — Suited for filtering, coupling and decoupling tasks in consumer and professional audio circuits where low leakage and reliable ripple handling are required.
• Power Filtering — Compact through-hole solution for local power smoothing in small power-supply and amplifier stages.
• Legacy and Repair Boards — Form-factor compatibility with radial-lead layouts makes this part appropriate for repair and maintenance of existing designs using Nichicon UKL series parts.

Unique Advantages

• Low-leakage performance: The specified 6.8 µA leakage supports stable bias conditions and reduced standby current in sensitive circuits.
• Broad ripple handling: Defined ripple ratings at 120 Hz and 10 kHz (250 mA / 500 mA) provide predictable behavior across low and high frequency ripple environments.
• Compact, space-efficient can: φ10 × 12.5 mm footprint with 5 mm lead spacing enables dense through-hole layouts and straightforward PCB placement.
• Elevated temperature endurance: 2000 hours at 85°C provides defined reliability for sustained operation in warm environments.
• RoHS compliant: Conforms to RoHS directives for environmental and regulatory consistency.
• Simple through-hole mounting: Radial-lead format supports easy hand or wave solder assembly and replacement tasks.

Why Choose UKL1H680KPD?

UKL1H680KPD delivers a focused combination of low leakage, clear ripple-current specifications, and a compact radial-can package from Nichicon's UKL series. It is well suited to audio and small power-filtering roles where predictable leakage and ripple performance are required in a through-hole form factor.

Because this part is scheduled for discontinuation (End Of Life) and is not recommended for new designs, it is most appropriate for repair, maintenance, or continuity-of-supply needs where matching an existing specification is required.
