UKA1H471MHD

The UKA1H471MHD is an aluminum electrolytic capacitor optimized for high‑grade audio equipment. It is a radial‑lead, polarized can capacitor delivering 470 µF at a rated voltage of 50 V with a wide operating temperature range and extended endurance.

Designed for audio applications that require stable filtering and smoothing across a broad temperature range, this capacitor combines defined loss characteristics, controlled leakage, and rated ripple capability to support reliable power handling in professional audio systems.

Key Features

• Capacitance & Voltage: 470 µF nominal capacitance at a rated voltage of 50 V with ±20% tolerance (measured at 120 Hz, 20 °C).
• Temperature Range & Lifetime: Operating range from −55 °C to +105 °C and an endurance rating of 2000 hours at 105 °C.
• Low Loss (tan δ): Tangent of loss angle specified at 0.14 (120 Hz, 20 °C) for the 50 V rating, supporting controlled dissipation in audio circuits.
• Leakage Current: Specified leakage current limits of 0.03CV after 1 minute (705 µA for this part) and 0.01CV after 2 minutes (235 µA for this part) at 20 °C.
• Ripple Current Capability: Rated ripple current of 530 mA at 120 Hz, 105 °C and 795 mA at 10 kHz, providing headroom for supply smoothing under audio load conditions.
• Package & Mounting: Radial lead (can) construction in a φ12.5×20 mm case with 5 mm lead spacing (±0.5 mm), available in bulk or bag packing.
• AEC Qualification: Rated AEC‑Q200, reflecting series qualification for demanding environmental profiles where AEC‑Q200 is required.
• Mass Production Availability: Part is in mass production and supplied without terminal forming for straightforward PCB assembly or hand‑wiring.

Typical Applications

• High‑grade Audio Equipment: Filtering and supply smoothing in amplifiers, preamplifiers, and other professional audio devices where stable capacitance and low loss at audio frequencies matter.
• Audio Power Supplies: Bulk reservoir and decoupling in audio power rails, supported by the capacitor’s rated ripple current at operating temperature.
• Industrial and Environmental Applications: Use in equipment requiring wide temperature operation (−55 °C to +105 °C) and defined endurance at elevated temperatures.

Unique Advantages

• Audio‑oriented electrical profile: 470 µF capacitance and a 50 V rating with a low tan δ (0.14) at 120 Hz, providing predictable behavior in audio signal and power paths.
• Wide operating temperature: −55 °C to +105 °C specification enables use across temperature extremes without changing specified performance limits.
• Measured ripple handling: 530 mA at 120 Hz (105 °C) and higher frequency ripple specification (795 mA at 10 kHz) make it suitable for real‑world audio power demands.
• Defined leakage behavior: Specified leakage currents after 1 and 2 minutes provide predictable bias and recovery characteristics for system designers.
• Radial can form factor: Compact φ12.5×20 mm can with 5 mm lead spacing eases integration into through‑hole boards and chassis‑mounted audio designs.
• AEC‑Q200 rated series: Series qualification supports designs that require established environmental qualification coverage.
