UBW1H471MHD

The UBW1H471MHD is a radial-lead aluminum electrolytic capacitor offering 470 µF at a 50 V rating in a compact φ12.5 × 25 mm can. Designed for high-temperature operation up to 135°C and a 3000-hour endurance rating, it targets power filtering and bulk energy storage in demanding environments.

With low impedance (55 mΩ), defined ripple current capability at both low and high frequencies, and AEC‑Q200 recognition, this part is positioned for reliable use in automotive and industrial power applications where temperature, lifetime and ripple handling matter.

Key Features

• Capacitance & Voltage: 470 µF nominal capacitance with a 50 V rated voltage and tolerance of -20% to +20% for predictable energy storage and decoupling.
• High‑temperature, Long life: Rated for operation from -55°C to +135°C with a specified endurance of 3000 hours at 135°C.
• Ripple current performance: Low-frequency ripple current of 1.1055 A (120 Hz) and high-frequency ripple current of 1.65 A (10 kHz) to handle AC stress in power circuits.
• Low impedance & dissipation: Impedance of 55 mΩ and a tangent of loss angle (tan δ) of 0.1 at 20°C, 120 Hz, supporting low-loss filtering and improved transient response.
• Radial lead package: φ12.5 × 25 mm can with 5 mm lead spacing (±0.5 mm) for through-hole mounting and straightforward PCB implementation.
• Leakage current: Specified leakage current of 705 µA for predictable quiescent behavior in bias applications.
• Automotive-grade recognition: AEC‑Q200 rating and explicit listing of Automotive in applications provide qualification for vehicle systems.
• Packaging options: Available in bulk (no terminal forming) or bag packing to suit assembly and handling preferences.

Typical Applications

• Automotive power rails: Bulk energy storage and smoothing on 50 V systems in under-hood or high-temperature zones, leveraging the AEC‑Q200 recognition and 135°C endurance.
• DC–DC converters and power supplies: Output filtering and decoupling where low impedance and rated ripple current reduce voltage ripple and thermal stress.
• Industrial control electronics: Energy buffering and transient suppression in motor drives, inverters and PLC power stages exposed to elevated temperatures.
• Embedded power modules: Local bulk capacitance for power conditioning in compact through-hole assemblies using radial lead mounting.

Unique Advantages

• High-temperature endurance: 3000 hours at 135°C supports longer in‑field life in thermally challenging applications.
• Qualified for automotive use: AEC‑Q200 recognition and explicit automotive application listing simplify selection for vehicle systems.
• High ripple handling across frequency: Specified ripple currents at 120 Hz and 10 kHz allow confident design for both low- and high-frequency stress.
• Compact radial can: φ12.5 × 25 mm size and 5 mm lead spacing provide a small-footprint solution for through-hole assemblies.
• Low impedance and controlled loss: 55 mΩ impedance and tan δ of 0.1 (20°C, 120 Hz) deliver efficient filtering with reduced heat generation.
• Measured leakage specification: 705 µA leakage current gives deterministic quiescent current budgeting for power-sensitive designs.
