UKL0J681MPD

The UKL0J681MPD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UKL low-leakage series. It delivers 680 µF capacitance at a 6.3 V rating in a compact φ10 × 16 mm can, designed for applications that benefit from low leakage and measurable ripple handling.

Key electrical attributes include a low leakage current specification (8.568 µA), rated ripple currents of 480 mA at 120 Hz and 720 mA at 10 kHz, and an operating range of −40°C to 85°C with a rated life of 2000 hours at 85°C. Status: End Of Life — products in this series are scheduled for discontinuation and are not recommended for new designs.

Key Features

• Capacitance & Tolerance — 680 µF nominal capacitance with ±20% tolerance (M) at 120 Hz, 20°C.
• Voltage Rating — Rated for 6.3 V operation, suitable where low-voltage energy storage and filtering are required.
• Low Leakage Current — Specified leakage current of 8.568 µA (measured after 2 minutes at 20°C for this case size), supporting designs that require minimized standby loss.
• Ripple Current Performance — Low-frequency ripple current of 480 mA at 120 Hz and high-frequency ripple current of 720 mA at 10 kHz, with frequency coefficients defined in the UKL series datasheet.
• Endurance & Temperature Range — Rated life of 2000 hours at 85°C; operating temperature range −40°C to 85°C.
• Package & Mounting — Radial lead, can-style package (φ10 × 16L) with 5 mm lead spacing and 0.5 mm lead spacing tolerance; available in Bulk (no terminal forming) or Bag packing.
• RoHS Compliance — Compliant with RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio circuits — Suitable for audio-related power supply filtering and decoupling where 6.3 V and 680 µF meet system requirements, and where low leakage helps preserve signal integrity.
• Low-voltage power rails — Energy storage and smoothing on low-voltage rails that require moderate ripple handling up to the specified 480 mA (120 Hz) and 720 mA (10 kHz).
• General-purpose electronics — Compact radial-lead solution for board-level filtering and bulk decoupling in small form-factor designs operating within the specified temperature and lifetime limits.

Unique Advantages

• Low standby loss: The specified leakage current of 8.568 µA supports circuits where minimizing quiescent current is important.
• Measurable ripple capability: Defined ripple current ratings at both low and high frequencies (480 mA at 120 Hz, 720 mA at 10 kHz) enable predictable thermal and performance planning.
• Compact radial can: φ10 × 16 mm package offers a small footprint and easy radial-lead mounting for through-hole assemblies.
• Robust temperature specification: −40°C to 85°C operating range with 2000-hour life at 85°C provides clarity for thermal design and lifetime budgeting.
• Packaging flexibility: Available in Bulk (no terminal forming) or Bag packing to accommodate different production and handling preferences.
• Regulatory compliance: RoHS compliance aligns with environmental requirements for many markets.
