UKW1H102MHD

The UKW1H102MHD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UKW series, specified at 1000 µF with a 50 V rating. Engineered for audio and AV equipment, it combines high capacitance in a compact φ12.5 × 25 mm can with 5 mm lead spacing for through-hole applications.

This part delivers sustained performance across a –40°C to +85°C operating range and a rated endurance of 2000 hours at 85°C, making it suitable for power smoothing, decoupling and ripple suppression in audio power supplies and related systems.

Key Features

• Capacitance & Tolerance — 1000 µF nominal capacitance with ±20% tolerance for bulk energy storage and smoothing in power circuits.
• Voltage Rating — 50 V rated voltage suitable for medium-voltage audio and AV power rails.
• Ripple Current Capability — 1.3 A ripple current at 120 Hz and 1.495 A at 10 kHz, supporting both low- and high-frequency ripple conditions.
• Leakage Current — Specified leakage current of 1500 µA, enabling predictable standby and quiescent behavior in DC circuits.
• Thermal and Lifetime Performance — Rated for operation from −40°C to +85°C with an endurance rating of 2000 hours at 85°C.
• Package & Mounting — Radial lead, can-style package (φ12.5 × 25 mm) with 5 mm lead spacing for easy through-hole assembly; shipped in bulk bag packing for mass production use.
• Audio-oriented Electrolyte — Part of the UKW series developed for AV/audio equipment to achieve a balanced sound characteristic using a series-specific electrolyte formulation.
• RoHS Compliant — Complies with RoHS requirements.

Typical Applications

• Audio Equipment — Power supply smoothing and decoupling in amplifiers and preamplifiers where 1000 µF capacitance and 50 V rating provide stable supply rails and reduced hum.
• AV Systems — Energy storage and ripple suppression in receivers, mixers and other AV components that benefit from the UKW series’ audio-focused electrolyte.
• Power Filters for Bench and Industrial Electronics — Bulk filtering and transient buffering on 50 V rails where elevated ripple handling at both 120 Hz and 10 kHz is required.

Unique Advantages

• Balanced audio performance: Series electrolyte development targets harmonic balance for AV applications, supporting audio-grade power decoupling.
• Dual-frequency ripple handling: Rated ripple currents at 120 Hz and 10 kHz provide clear specifications for designers addressing both mains-related and higher-frequency switching ripple.
• Compact, through-hole form factor: φ12.5 × 25 mm can with 5 mm lead spacing offers high capacitance in a small package for space-constrained boards.
• Predictable thermal endurance: 2000 hours at 85°C allows designers to qualify lifetime behavior under elevated operating temperatures.
• Production-friendly packing: Bulk (no terminal forming) / bag packing supports high-volume assembly workflows.
