UBW1H100MPD

The UBW1H100MPD is a radial-lead aluminum electrolytic capacitor designed for high-temperature, long-life applications. It delivers 10 µF at a 50 V rating with polarization and is optimized for demanding environments where elevated temperature endurance and reliable ripple handling are required.

Built to support automotive-grade designs and other high-reliability systems, this capacitor combines a compact φ8 × 11.5 mm can with performance characteristics suited to power filtering, decoupling and general power electronic functions.

Key Features

• Capacitance & Voltage — 10 µF nominal capacitance with a rated voltage of 50 V and tolerance of −20% to +20% for predictable capacitance budgeting.
• High-temperature endurance — Rated for operation from −55 °C to +135 °C with a specified lifetime of 1000 hours at 135 °C.
• Low dissipation factor — tanδ of 0.1 measured at 20 °C, 120 Hz (for the 50 V rating), supporting efficient filtering with reduced loss.
• Ripple current capability — 90 mA at 120 Hz (low frequency) and 180 mA at 10 kHz (high frequency) to handle AC ripple in power rails and converters.
• Leakage and impedance — Specified leakage current of 15 µA and impedance of 750 mΩ for stable DC performance and predictable ESR behavior.
• Mechanical and packaging — Radial, can-style package with φ8 × 11.5 mm size, 3.5 mm lead spacing (±0.5 mm), and supplied in bulk or bag packing (no terminal forming).
• Automotive qualification — Designed to AEC-Q200 requirements and listed for automotive applications where that qualification is required.
• Identification — Marked with white lettering on a blue sleeve for visual verification.

Typical Applications

• Automotive electronics — Bulk and decoupling use in control modules and power distribution circuits that require high-temperature endurance and AEC-Q200 qualification.
• Power-supply filtering — Smoothing and ripple suppression in DC/DC converters and regulator outputs where elevated operating temperature and ripple current capability are needed.
• Motor-control electronics — Local decoupling and damping in motor-drive power stages exposed to thermal stress and continuous ripple currents.
• Sensor and actuator power rails — Stable energy storage and noise suppression for sensors and actuators operating across wide temperature ranges.

Unique Advantages

• High-temperature reliability: Rated to +135 °C with a specified 1000-hour life at that temperature, providing endurance where thermal margin is limited.
• Automotive-capable qualification: AEC-Q200 rating supports use in automotive systems that require standardized passive-component qualification.
• Balanced ripple handling: Dual specification for low- and high-frequency ripple current (90 mA at 120 Hz, 180 mA at 10 kHz) addresses both line-frequency and switching-frequency stress.
• Compact radial form factor: φ8 × 11.5 mm can with 3.5 mm lead spacing fits tight board layouts while providing axial stability for through-hole assemblies.
• Predictable electrical performance: Low tanδ (0.1 at 50 V, 120 Hz) and specified impedance and leakage current allow engineers to model loss and leakage in power budgets.
