UKL1E680KPD

The UKL1E680KPD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UKL low-leakage series. It provides 68 µF nominal capacitance at a 25 V rating with a ±10% tolerance and is optimized for applications where low leakage and defined ripple handling are important.

Key characteristics include very low leakage current (3.4 µA), specified ripple current performance (230 mA at 120 Hz and 460 mA at 10 kHz), a compact φ8 × 11.5 mm radial can package with 3.5 mm lead spacing, and an operating temperature range of –40 °C to 85 °C. Status: End Of Life — this product is scheduled for discontinuation and is not recommended for new designs.

Key Features

• Capacitance & Voltage — 68 µF nominal capacitance with a 25 V rated voltage and a capacitance tolerance of ±10% (K).
• Low Leakage Current — Specified leakage current of 3.4 µA for reduced standby losses and improved performance in bias-sensitive circuits.
• Ripple Current Performance — Rated low-frequency ripple current of 230 mA at 120 Hz and high-frequency ripple current of 460 mA at 10 kHz to support power smoothing and decoupling in dynamic loads.
• Endurance & Reliability — Life rating of 2000 hours at 85 °C, with shelf-life and endurance characteristics defined in the UKL series datasheet.
• Package & Mounting — Radial lead (can) package, dimensions φ8 × 11.5 mm, lead spacing 3.5 mm (±0.5 mm), suitable for through-hole mounting and manual or automated insertion processes.
• Temperature Range — Operates from –40 °C to 85 °C to cover a broad range of consumer and professional ambient conditions.
• Compliance — RoHS compliant as part of the UKL series.

Typical Applications

• Audio equipment — Decoupling and power-supply smoothing in amplifiers, preamplifiers, and audio modules where low leakage and defined ripple handling support clear audio performance.
• Consumer audio devices — Filtering and energy storage in compact, through-hole designs that require a small radial can and tight lead spacing.
• Power decoupling in signal chains — Local supply stabilization for audio front-ends and modules that benefit from long endurance at elevated operating temperature.

Unique Advantages

• Low quiescent leakage: 3.4 µA leakage current reduces bias drift and minimizes idle power loss in sensitive audio circuits.
• Frequency-aware ripple capability: Rated ripple currents at both 120 Hz and 10 kHz allow designers to size capacitors with confidence across low and high-frequency load conditions.
• Compact radial form factor: φ8 × 11.5 mm can with 3.5 mm lead spacing provides a small-footprint, through-hole solution for board-level power needs.
• Defined life rating: 2000 hours at 85 °C gives predictable endurance for thermal and lifetime planning in production designs.
• Regulatory compliance: RoHS-compliant construction supports restriction-of-hazardous-substance requirements.

Why Choose UKL1E680KPD?

UKL1E680KPD delivers a focused combination of low leakage, compact radial packaging, and measurable ripple-current capability that makes it appropriate for audio-focused power decoupling and smoothing applications. Its specified endurance at 85 °C and RoHS compliance provide predictable performance and regulatory alignment for existing designs.

Because this part is scheduled for discontinuation and is not recommended for new designs, it is best suited for maintenance, repair, or legacy system support where an exact form-fit-function replacement from the UKL series is required.
