UBW1A102MPD

The UBW1A102MPD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UBW series, offering 1000 µF capacitance at a 10 V rating in a compact φ10×20 mm can. It is a polarized, through‑hole component designed for demanding temperature environments.

With an operating range of −55°C to +135°C, AEC‑Q200 qualification, and long-life endurance, this capacitor is aimed at applications that require stable bulk capacitance, high ripple handling and proven high‑temperature reliability.

Key Features

• Capacitance & Voltage — 1000 µF (1 mF) nominal capacitance with ±20% tolerance at 120 Hz, rated for 10 V operation.
• High‑Temperature Endurance — Rated for operation from −55°C to +135°C with a 2000 hour endurance specification at 135°C.
• Ripple Current Performance — Low‑frequency ripple current 737 mA at 120 Hz and high‑frequency ripple current 1.1 A at 10 kHz, supporting power smoothing and decoupling under AC stress.
• Low Impedance — Typical impedance of 57 mΩ helps minimize voltage drop under transient and ripple conditions.
• Leakage Current — Specified leakage current of 300 µA for predictable bias behavior after application of rated voltage.
• Mechanical & Packaging — Radial lead can package, φ10×20 mm size with 5 mm lead spacing (±0.5 mm); available in bulk (no terminal forming) or bag packing.
• Automotive Qualification — AEC‑Q200 rated for use in automotive electronics and other applications requiring component qualification.

Typical Applications

• Automotive Electronics — Power rail smoothing and bulk energy storage in automotive control modules where AEC‑Q200 qualification and high operating temperature are required.
• Power Supply Filtering — Bulk decoupling and ripple suppression for DC‑DC converters and linear regulators, leveraging the high ripple current capability and low impedance.
• High‑Temperature Electronics — Use in assemblies that operate in elevated ambient temperatures, taking advantage of the −55°C to +135°C range and long life at 135°C.

Unique Advantages

• High‑temperature reliability: 2000 hours endurance at 135°C provides predictable lifetime performance in hot environments.
• Automotive‑grade qualification: AEC‑Q200 rating supports deployment in automotive-grade designs requiring qualified passive components.
