UBW1H102MHD

The UBW1H102MHD is a radial‑lead aluminum electrolytic capacitor offering 1000 µF capacitance at a 50 V rating. Designed for high‑temperature, long‑life applications, it combines low impedance and substantial ripple handling in a compact φ16 × 30.5 mm can.

Targeted at demanding power systems, including automotive electronics, this AEC‑Q200‑rated component delivers 3000 hours of endurance at 135°C, making it suitable for designs that require robust thermal performance and reliable bulk energy storage.

Key Features

• Capacitance & Voltage — 1000 µF (±20%) capacitance at a 50 V rating provides significant bulk charge storage for DC rail smoothing and energy buffering.
• High‑Temperature Endurance — Rated operating range −55°C to +135°C with a specified lifetime of 3000 hours at 135°C, supporting prolonged operation in elevated ambient conditions.
• Low Impedance & Ripple Capability — Impedance of 31 mΩ and ripple currents of 1.628 A at 120 Hz and 2.43 A at 10 kHz enable effective filtering of both low‑ and high‑frequency ripple.
• Loss Characteristics — Tangent of loss angle (tanδ) of 0.10 measured at 20°C and 120 Hz for the 50 V rating, supporting predictable AC performance.
• Leakage & Polarization — Polarized aluminum electrolytic with a measured leakage current of 1500 µA, consistent with the capacitor’s capacitance and voltage class.
• Package & Mounting — Radial lead, can package (φ16 × 30.5 mm) with 7.5 mm lead spacing (±0.5 mm) for through‑hole PCB mounting and straightforward assembly.
• Qualification — AEC‑Q200 rating and series datasheet coverage indicate suitability for applications requiring component‑level automotive qualification.
• Packaging Options — Supplied in bulk (no terminal forming) or bag packing to support different assembly workflows.

Typical Applications

• Automotive power electronics — Suited to automotive modules and subsystems that require AEC‑Q200 qualification, high temperature tolerance, and reliable bulk capacitance.
• High‑temperature power supplies — Bulk smoothing and decoupling in power supplies that operate up to 135°C, leveraging 1000 µF storage and rated 50 V tolerance.
• DC rail smoothing and transient support — Low impedance (31 mΩ) and high ripple current handling (up to 2.43 A at 10 kHz) for stabilizing DC rails and absorbing transient loads.

Unique Advantages

• Proven high‑temperature performance: 3000 hours at 135°C offers extended life in thermally stressed environments, reducing replacement frequency.
• Automotive‑grade qualification: AEC‑Q200 rating supports use in vehicle electronic subsystems where industry qualification is required.
• Strong ripple handling across frequencies: Measured ripple current values at 120 Hz and 10 kHz allow a single component to address both low‑ and high‑frequency filtering needs.
• Compact power density: 1000 µF in a φ16 × 30.5 mm can provides substantial capacitance in a small footprint for space‑constrained boards.
• Deterministic AC behavior: A tanδ of 0.10 at 20°C/120 Hz enables predictable loss and thermal calculations in design validation.
• Flexible assembly options: Radial lead form and bulk or bag packing simplify through‑hole assembly and handling for production variants.
