UKT1H471MHD

The UKT1H471MHD is a radial-lead aluminum electrolytic capacitor in the UKT series designed for general audio equipment and applications requiring a wide temperature range. It provides 470 µF capacitance at a 50 V rating in a compact φ12.5×20 mm can with 5 mm lead spacing.

Engineered for reliability in demanding environments, this part combines broad operating temperature (-55°C to 105°C), AEC-Q200 qualification, and endurance specified at 1000 hours at 105°C, making it suitable for audio electronics and industrial designs where temperature and lifetime matter.

Key Features

• Capacitance & Voltage: 470 µF nominal capacitance with a 50 V rated voltage and ±20% tolerance for bulk filtering and energy storage in power rails.
• Temperature Range & Endurance: Rated for -55°C to +105°C with a life rating of 1000 hours at 105°C, supporting long-term operation under elevated temperatures.
• Ripple Current Performance: Low-frequency ripple current 530 mA at 120 Hz and high-frequency ripple current 795 mA at 10 kHz, enabling effective smoothing across a range of frequencies.
• Loss and Leakage: Tan δ of 0.14 (measured at 20°C, 120 Hz) and specified leakage current of 705 µA, giving predictable dissipation and minimal standby loss.
• Package & Mounting: Radial lead, can-style package sized φ12.5×20 mm with 5 mm lead spacing (±0.5 mm), available in bulk or bag packing—suitable for through‑hole assembly.
• Qualification & Compliance: AEC-Q200 rated and offered in a series described as compliant to the RoHS directive, supporting regulated and reliability-conscious designs.

Typical Applications

• Audio Equipment: Power supply smoothing, decoupling and energy reservoir duties in amplifiers and audio processing systems that require wide temperature operation.
• Power Supply Filtering: Bulk filtering and ripple suppression on DC rails where 470 µF at 50 V and defined ripple current capability improve regulation and transient response.
• Industrial Electronics: General-purpose filtering and energy storage in control and signal-conditioning modules operating across a wide temperature range.

Unique Advantages

• Wide operating temperature band: -55°C to +105°C rating supports designs exposed to extreme temperature cycles or elevated ambient conditions.
• High-temperature endurance: 1000 hours at 105°C provides predictable life expectancy for applications where prolonged thermal stress occurs.
• Frequency-flexible ripple handling: Specified ripple currents at both 120 Hz (530 mA) and 10 kHz (795 mA) give designers confidence across low- and high-frequency filtering needs.
• Compact radial can: φ12.5×20 mm package with 5 mm lead spacing balances capacitance density with straightforward through-hole mounting and mechanical stability.
• Traceable quality standard: AEC-Q200 rating indicates qualification to demanding reliability criteria relevant to many high-reliability electronics programs.
• Predictable electrical behavior: Specified tan δ (0.14 at 20°C, 120 Hz) and defined leakage current support accurate loss and standby current budgeting.
