UBW1C331MPD

The UBW1C331MPD is a radial-lead aluminum electrolytic capacitor offering 330 µF capacitance at a 16 V rating. Designed for high-temperature, long-life applications, this can-style capacitor is optimized for compact power-filtering and decoupling roles in demanding environments.

Key value propositions include extended endurance at elevated temperature (rated for 135°C operation with a 2000 hour life), AEC-Q200 qualification, and specifications tailored for robust ripple handling and low impedance in small package dimensions.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a 16 V rated voltage and capacitance tolerance of ±20% (−20% to +20%).
• High-Temperature Endurance — Rated to operate from −55°C to +135°C with an endurance rating of 2000 hours at 135°C.
• AEC Qualification — AEC-Q200 rated, supporting use in designs requiring automotive-grade component qualification.
• Low Loss — Tangent of loss angle (tan δ) of 0.16 at 20°C, 120 Hz (16 V rating), supporting efficient filtering performance.
• Ripple Current Capability — Low-frequency ripple current 455.6 mA (120 Hz) and high-frequency ripple current 680 mA (10 kHz), enabling effective smoothing of power rails across frequency ranges.
• Leakage & Impedance — Specified leakage current of 158.4 µA and impedance of 100 mΩ, providing predictable bias behavior and low-loss performance in small assemblies.
• Form Factor — Compact radial can: diameter φ10 mm × length 12.5 mm, lead spacing 5.0 mm (±0.5 mm), suitable for through‑hole assemblies where space is limited.
• Packaging — Available in bulk (no terminal forming) and bag packing to support a variety of production workflows.

Typical Applications

• Automotive electronics — Energy smoothing and decoupling on low-voltage automotive boards where AEC‑Q200 qualification and high-temperature endurance are required.
• Power supply filtering — Local bulk decoupling and output smoothing for DC/DC converters and linear regulators operating at or below 16 V.
• Industrial controls — Capacitive energy storage and ripple suppression in compact embedded controllers exposed to extended temperature ranges.
• Consumer and handheld devices — Space-efficient bulk capacitance for small form-factor power systems that require reliable ripple performance.

Unique Advantages

• High-temperature longevity: Rated for 2000 hours at 135°C, enabling extended service life in elevated-temperature environments.
• AEC-Q200 rated: Provides a documented qualification path for automotive and high-reliability system designs.
• Broad ripple handling: Specified ripple current at both low and high frequencies (455.6 mA @120 Hz, 680 mA @10 kHz) supports versatile power-filtering demands.
• Compact, through-hole package: φ10 × 12.5 mm can and 5.0 mm lead spacing deliver a small footprint while retaining robust capacitance and low impedance (100 mΩ).
• Predictable electrical performance: Low tan δ (0.16 at 20°C, 120 Hz) and defined leakage current (158.4 µA) make selection and modeling straightforward for engineers.
• Production-friendly packaging: Bulk and bag packing options simplify handling for assembly and inventory processes.
