UHW1J561MHD

The UHW1J561MHD is a miniature, high-reliability aluminum electrolytic capacitor in a radial-lead can designed for general-purpose electronic equipment. It combines a 560 µF capacitance at 63 V with low impedance and elevated ripple-current capability to support power filtering and energy-storage functions in compact designs.

Engineered for sustained operation across a wide temperature range (−40°C to 105°C) and long endurance (12,000 hours at 105°C), this capacitor is targeted at applications that require compact size, reliable performance, and RoHS-compliant materials.

Key Features

• Electrical Characteristics — 560 µF nominal capacitance at 63 V with tolerance −20% to +20%, and rated tan δ of 0.09 (measured at 20°C, 120 Hz).
• Low Impedance — Specified impedance of 140 mΩ supports lower AC voltage drop and improved performance at higher frequencies.
• High Ripple Current Capability — Low-frequency ripple current 1.23 A (120 Hz) and high-frequency ripple current 2.46 A (10 kHz), enabling improved handling of AC stress in power circuits.
• Leakage Current — Measured leakage current of 352.8 µA after application of rated voltage (20°C), supporting predictable bias behavior.
• Long Endurance — Endurance rated at 12,000 hours at 105°C under DC bias plus rated ripple current, with post-test limits on capacitance change, tan δ, and leakage current defined by the series specification.
• Compact Radial Package — φ12.5 × 25 mm can with 5.0 mm lead spacing (±0.5 mm) in a radial-lead format for through-hole assemblies; available in bulk (no terminal forming) or bag packing.
• Operating Temperature — Wide operating range from −40°C to +105°C for use in varied thermal environments.
• RoHS Compliant — Manufactured in accordance with RoHS directive requirements.

Typical Applications

• General-purpose power filtering — Low impedance and high ripple-current ratings make this capacitor suitable for smoothing and decoupling in power rails of electronic equipment.
• Power-supply energy storage — 560 µF capacitance and robust endurance support bulk energy buffering in compact, through-hole power designs.
• High-frequency decoupling — Lower impedance at higher frequencies helps stabilize voltage rails in mixed-signal or switching environments.

Unique Advantages

• Compact footprint with high capacitance: 560 µF in a φ12.5 × 25 mm can reduces board area while delivering substantial energy storage.
• High ripple-current handling: Specified ripple current at both low and high frequencies minimizes heating and extends service life under AC stress.
• Predictable impedance and loss characteristics: 140 mΩ impedance and tan δ = 0.09 (63 V, 120 Hz) provide quantifiable performance for power-design calculations.
• Long endurance at elevated temperature: 12,000 hours at 105°C supports reliable operation in thermally demanding applications.
• Through-hole radial format: 5.0 mm lead spacing and standard radial can simplify assembly in legacy and industrial PCBs; packaging options include bulk or bag packing.
• RoHS compliance: Meets regulatory material requirements for restricted substances.
