UKL1A102MHD

The UKL1A102MHD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UKL series, designed for low leakage applications. It delivers 1000 µF capacitance at a 10 V rating in a compact φ12.5 × 20 mm package with 5 mm lead spacing, targeting audio and related electronic equipment that require reliable smoothing and decoupling.

Key value points include low leakage current, defined ripple-current capability at both low and high frequencies, RoHS compliance, and a rated endurance of 2000 hours at 85°C. Note: Status is End Of Life.

Key Features

• Electrical Capacity and Voltage — 1000 µF capacitance with a 10 V rated voltage and ±20% tolerance, suitable for energy storage, smoothing and decoupling tasks within the specified voltage.
• Low Leakage Current — Leakage current specified at 20 µA, supporting designs where minimal bleed and long-term charge retention are important.
• Ripple Current Performance — Low-frequency ripple current of 810 mA at 120 Hz and high-frequency ripple current of 931.5 mA at 10 kHz, enabling effective filtering across a broad frequency range.
• Reliability and Endurance — Life rating of 2000 hours at 85°C; after endurance testing the capacitor meets specified limits for capacitance change, tan δ and leakage current as defined by the series specifications.
• Temperature Range — Operating range from −40°C to +85°C to accommodate industrial and consumer ambient conditions within that envelope.
• Mechanical & Packaging — Radial, can-style package sized φ12.5 × 20 mm (L: 2.0 cm × D: 1.25 cm) with 5 mm lead spacing (±0.5 mm). Available in bulk (no terminal forming) or bag packing.
• Regulatory — RoHS compliant per the product data.

Typical Applications

• Audio Power Supply Filtering — Provides smoothing and decoupling in audio amplifier and preamplifier power rails where low leakage and stable capacitance aid noise performance.
• Audio Signal Conditioning — Used for DC blocking and reservoir capacitance in audio electronics where stable low-frequency behavior and defined ripple handling are required.
• Consumer and Professional Audio Equipment — Suited to devices that benefit from compact radial electrolytics with measurable ripple-current capability and endurance at elevated temperature.

Unique Advantages

• Low Leakage for Stable DC Performance: Specified leakage current of 20 µA helps maintain bias and reduces unwanted discharge in sensitive audio circuits.
• Defined Ripple Handling Across Frequencies: Rated ripple currents at both 120 Hz (810 mA) and 10 kHz (931.5 mA) support effective filtering for power-supply and high-frequency noise components.
• Compact Radial Can Package: φ12.5 × 20 mm size with 5 mm lead spacing delivers a small footprint for through-hole assemblies while preserving capacitance density.
• Endurance Characterized at 85°C: 2000-hour life rating at 85°C provides a measurable reliability baseline for thermal stress in typical operating environments.
• RoHS Compliant: Meets applicable RoHS requirements as stated in the product data.
