UBW1A472MHD

The UBW1A472MHD is a miniature, high-reliability aluminum electrolytic capacitor in a radial‑lead can from Nichicon’s UBW series. It provides 4.7 mF (4700 µF) capacitance at a 10 V rating in a compact φ16 × 30.5 mm package with 7.5 mm lead spacing.

Designed for demanding thermal environments, this high‑temperature unit is specified for operation from −55 °C to +135 °C, carries an AEC‑Q200 rating, and is endurance‑tested to 3000 h at 135 °C—making it suitable for applications that require long life, high ripple handling and low impedance in compact power circuits.

Key Features

• High Capacitance, Low Voltage — 4.7 mF (4700 µF) nominal capacitance at a 10 V rated voltage for bulk energy storage and decoupling in low‑voltage power rails.
• High Temperature Endurance — Rated operating temperature −55 °C to +135 °C with a specified life of 3000 hours at 135 °C, supporting sustained operation in elevated temperature environments.
• AEC‑Q200 Qualified — AEC‑Q200 rating for use in applications requiring industry standard reliability verification.
• Ripple Current Capability — Low‑frequency ripple current ~1.816 A at 120 Hz and high‑frequency ripple current 2.71 A at 10 kHz, enabling effective smoothing under dynamic load conditions.
• Low Impedance — Specified impedance of 20 mΩ helps minimize voltage drop and heat generation in high current circuits.
• Compact Radial Package — φ16 × 30.5 mm can with 7.5 mm lead spacing and radial lead mounting for through‑hole PCB designs; available as bulk or bag packing (no terminal forming).
• Electrical Characteristics — Capacitance tolerance −20% to +20%, tangent of loss angle (tan δ) 0.26 measured at 20 °C, 120 Hz; leakage current 1410 µA.

Typical Applications

• Automotive Power Electronics — Suitable for automotive electronics that require high temperature endurance and AEC‑Q200 qualification; provides bulk smoothing and energy buffering where elevated ambient temperatures are expected.
• DC‑DC Converters and Power Supplies — Large capacitance combined with low impedance and multi‑kiloamp ripple handling supports output filtering and transient response in compact power modules.
• Industrial Controls and Power Modules — Long endurance at 135 °C and robust leakage/ripple characteristics make this capacitor appropriate for power conditioning in industrial equipment exposed to high thermal stress.

Unique Advantages

• Designed for High‑Temperature Duty: Rated to +135 °C with 3000 h endurance at that temperature, reducing the need for overspecifying thermal margin in hot environments.
• High Bulk Energy in a Small Footprint: 4700 µF in a φ16 × 30.5 mm can provides substantial capacitance where PCB area or height is constrained.
• High Ripple Handling with Low Loss: Specified ripple currents up to 2.71 A at 10 kHz and a 20 mΩ impedance help maintain low heating and efficient filtering under dynamic loads.
• AEC‑Q200 Qualification: Built to automotive reliability standards for designs that demand validated component robustness.
• Flexible Packaging Options: Available in bulk (no terminal forming) or bag packing to support different assembly and inventory workflows.
