UBT1H471MHD8

The UBT1H471MHD8 is a radial-lead aluminum electrolytic capacitor in the Nichicon UBT series, offering 470 µF capacitance at a 50 V rating. Designed for high-temperature, long-life operation, this polarized can-style capacitor is intended for demanding power applications, including automotive electronics where AEC-Q200 qualification and extended endurance are required.

Key values include high ripple tolerance, low impedance, and a wide operating temperature range of −40 °C to 125 °C, making it suitable for power smoothing, filtering and bulk energy storage in harsh environments.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with ±20% tolerance and a rated voltage of 50 V, suitable for mid-voltage power applications.
• High-temperature endurance — Rated for operation up to 125 °C with a specified lifetime of 10,000 hours at 125 °C for this case size and voltage.
• Ripple current handling — Low-frequency ripple current of 1.105 A (120 Hz) and high-frequency ripple current of 1.65 A (100 kHz) to support power supply filtering and transient loads.
• Low impedance — 55 mΩ impedance helps minimize voltage drop and heat generation under load.
• Leakage current — Specified leakage current of 705 µA after rated-voltage application, enabling predictable power-loss budgeting.
• Mechanical & packaging — Radial-lead, can-type package with dimensions φ12.5 × 25 mm, 5 mm lead spacing (±0.5 mm); available in bulk (no terminal forming) / bag packing.
• Automotive-capable and compliant — AEC-Q200 qualified and RoHS compliant for regulated production environments and automotive electronics.

Typical Applications

• Automotive electronics — Power filtering and bulk decoupling in control modules and power electronics where AEC-Q200 qualification and high-temperature endurance are required.
• Power supplies — Output smoothing and energy storage in DC–DC converters and regulated supplies that require high ripple handling and low impedance.
• Industrial equipment — Bulk decoupling and transient support in motor drives and instrumentation exposed to elevated ambient temperatures.
• Energy storage & backup — Short-term energy buffering and hold-up for systems requiring reliable capacitance at elevated temperatures.

Unique Advantages

• Long high-temperature life: 10,000 hours at 125 °C for the specified case and voltage provides predictable long-term performance in hot environments.
• Automotive-qualified reliability: AEC-Q200 qualification supports use in automotive-grade designs that demand component-level robustness.
• High ripple capability: Combined low-frequency and high-frequency ripple ratings (1.105 A and 1.65 A) allow a single capacitor to address a range of ripple conditions.
• Low ESR/impedance: 55 mΩ impedance helps reduce heat generation and improve voltage stability under load.
• Compact radial package: φ12.5 × 25 mm can with 5 mm lead spacing fits many PCB layouts while providing substantial capacitance for bulk energy storage.
• Regulatory compliance: RoHS compliance supports deployment in regulated manufacturing and end-products.
