UKL1E102MHD

The UKL1E102MHD is a low-leakage aluminum electrolytic capacitor in a radial-lead can, rated at 1000 µF and 25 V. It delivers defined ripple-current performance at both low and high frequencies and is targeted for audio applications and related power-supply filtering tasks.

Designed for through-hole mounting, this φ16 × 25 mm capacitor combines 1 mF capacitance, low leakage and a 2000-hour endurance at 85°C to provide reliable bulk energy storage and rail stabilization in equipment operating between −40°C and 85°C.

Key Features

• Electrical Performance — 1000 µF (1 mF) capacitance with ±20% tolerance and a 25 V rated voltage; polarized electrolytic construction for bulk energy storage.
• Low Leakage Current — Specified leakage current of 50 µA for reduced self-discharge and improved bias stability in long‑duration applications.
• Ripple Current Capability — Rated low-frequency ripple current of 1.01 A at 120 Hz and high-frequency ripple capability of 1.161 A at 10 kHz to support audio-frequency and higher-frequency supply ripple demands.
• Reliability & Endurance — Rated life of 2000 hours at 85°C with restoration to 20°C for post-test verification of characteristics.
• Operating Range — Specified operating temperature range of −40°C to 85°C for deployment in typical consumer and industrial ambient conditions.
• Package & Mounting — Radial-lead can, size φ16 × 25 mm, lead spacing 7.5 mm (±0.5 mm) designed for easy through-hole PCB assembly.
• Packaging Options — Supplied in bulk (no terminal forming) or bag packing to support assembly and service requirements.
• Regulatory Compliance — RoHS compliant per product data.
• Availability Status — Product is listed as End Of Life; check availability before specifying.

Typical Applications

• Audio power supply filtering — 1000 µF capacitance and specified ripple currents support smoothing and bulk storage on audio power rails.
• Amplifier decoupling — Low leakage and substantial capacitance help maintain stable bias and supply decoupling in audio amplifier circuits.
• Consumer audio equipment — Through-hole radial form factor and defined endurance make this component suitable for circuit boards in audio devices where 25 V ratings are required.

Unique Advantages

• Low self-discharge: 50 µA leakage current reduces drift and bias loss during idle periods, supporting stable performance in audio circuits.
• Frequency-aware ripple handling: Rated ripple currents at 120 Hz and 10 kHz provide measurable capability for both mains-related and higher-frequency ripple scenarios.
• Proven endurance at operating temperature: 2000-hour rating at 85°C gives a defined longevity metric for thermal-stressed designs.
• Easy through-hole integration: Radial-lead φ16 × 25 mm package with 7.5 mm lead spacing simplifies board layout and assembly for existing through-hole workflows.
• Regulatory alignment: RoHS compliance supports deployments where restricted-substance conformance is required.
• Flexible packing options: Bulk or bag packing supports both high-volume assembly and repair/maintenance use cases.
