UKL1V681MHD

The UKL1V681MHD is a Nichicon UKL series aluminum electrolytic capacitor engineered for low leakage current in a radial-lead can. It provides 680 µF capacitance at a 35 V rating with radial leads and is targeted at applications where moderate energy storage and controlled leakage are required, including audio circuitry.

This part offers defined ripple-current performance across low and high frequencies and is RoHS compliant. Note: this part is listed as End Of Life and the UKL series is scheduled to be discontinued.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with a rated voltage of 35 V and a tolerance of ±20% (M).
• Low Leakage Current — Specified leakage current of 47.6 µA, helping to limit DC leakage in sensitive circuits.
• Ripple Current Performance — Low-frequency ripple current 840 mA at 120 Hz and high-frequency ripple current 1.26 A at 10 kHz, supporting AC ripple handling across common audio frequencies.
• Endurance & Temperature — Rated life of 2000 hours at 85 °C with an operating temperature range of −40 °C to +85 °C.
• Package & Mounting — Radial lead, can-style package with dimensions φ16×25L mm and lead spacing 7.5 mm (±0.5 mm), suitable for through-hole PCB layouts.
• Polarized Type — Polarized aluminum electrolytic capacitor for DC filtering and energy storage applications.
• Packaging Options — Available in bulk (no terminal forming) or bag packing for flexible procurement quantities.
• Environmental Compliance — RoHS compliant per provided product information.

Typical Applications

• Audio — Suited for audio circuitry that requires bulk capacitance and controlled leakage for power supply decoupling and smoothing.
• Power Filtering — Used where moderate ripple-current capability and polarized bulk capacitance are needed on through-hole boards.
• General Electronics — Applicable in consumer and industrial designs requiring a radial aluminum electrolytic with defined endurance at elevated temperature.

Unique Advantages

• Stable bulk capacitance at 35 V: 680 µF provides substantial energy storage for decoupling and smoothing in power rails.
• Low leakage specification: 47.6 µA leakage current helps maintain DC stability in circuits sensitive to bleed and quiescent loss.
• Frequency-aware ripple handling: Specified ripple currents at 120 Hz (840 mA) and 10 kHz (1.26 A) give designers measurable AC performance across common frequency ranges.
• Compact radial package: φ16×25L mm can with 7.5 mm lead spacing simplifies through-hole layout integration while keeping board footprint modest.
• Temperature and endurance rating: Rated for −40 °C to +85 °C with 2000 hours life at 85 °C, supporting designs operating in elevated-temperature environments.
• RoHS compliant: Compliant construction for designs requiring restriction of hazardous substances.
