UKL1J151MHD

The UKL1J151MHD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UKL low-leakage series. It provides 150 µF nominal capacitance at a 63 V rating in a compact 12.5 mm diameter × 20 mm length can, optimized for through-hole assemblies.

Designed for audio and other circuits that benefit from low leakage and reliable ripple handling, this component combines low leakage current, specified ripple performance across low and high frequencies, RoHS compliance, and 2,000 hours endurance at 85 °C.

Key Features

• Electrical Core — 150 µF nominal capacitance with ±20% tolerance and a 63 V rated voltage for general-purpose energy storage and decoupling.
• Low Leakage — Part of Nichicon’s Low Leakage Current series; specified leakage current listed as 18.9 µA under the stated test conditions.
• Ripple Performance — Rated low-frequency ripple current of 450 mA at 120 Hz and high-frequency ripple current of 675 mA at 10 kHz to support filtering and smoothing in power and audio stages.
• Reliability & Endurance — Life endurance rated at 2000 hours at 85 °C with operating temperature range from −40 °C to +85 °C.
• Package & Mounting — Radial lead (polarized) can with φ12.5 × 20L dimensions and 5 mm lead spacing (±0.5 mm), supplied in bulk or bag packing (no terminal forming).
• Regulatory — RoHS compliant.

Typical Applications

• Audio circuits — Low-leakage characteristic and specified ripple handling make this capacitor suitable for coupling, smoothing, and power supply filtering in audio equipment.
• Through-hole assemblies — Radial-lead format and 5 mm lead spacing simplify bench prototyping, repairs, and through-hole production workflows.
• Low-leakage designs — Intended for circuits where reduced leakage current supports circuit stability and performance.
• Bulk procurement and repair — Available in bulk or bag packing for production runs and service inventory.

Unique Advantages

• Low leakage current: Specified leakage current of 18.9 µA supports applications that require minimal DC loss across the capacitor.
• Dual-frequency ripple capability: Explicit ripple ratings at 120 Hz (450 mA) and 10 kHz (675 mA) provide quantifiable performance for both low- and high-frequency filtering tasks.
• High-voltage rating in compact package: 63 V rating in a φ12.5 × 20 mm can allows higher-voltage applications without a large footprint.
• Durability at elevated temperature: 2000-hour endurance at 85 °C provides a defined lifecycle metric for thermal-stressed designs.
• RoHS compliant: Conforms to RoHS requirements for regulatory-compliant product builds.
• Through-hole convenience: Radial-lead, polarized can and standard lead spacing simplify assembly and replacement in legacy and new through-hole designs.
