UBT1A331MPD8

The UBT1A331MPD8 is a radial-lead aluminum electrolytic capacitor with 330 µF capacitance and a 10 V rated voltage. It is designed for high-temperature operation up to +125°C and for long endurance in demanding environments.

This part targets applications that require robust, low-impedance energy storage and ripple handling in compact radial-can packaging. It combines AEC-Q200 qualification and RoHS compliance with specifications tailored for extended high-temperature service.

Key Features

• Electrical performance — 330 µF capacitance with ±20% tolerance and a rated voltage of 10 V; nominal impedance of 150 mΩ supports low-loss operation.
• Ripple and leakage — Low-frequency ripple current 415.4 mA (120 Hz) and high-frequency ripple current 620 mA (100 kHz); leakage current specified at 99 µA.
• High-temperature endurance — Rated for operation from −40 °C to +125 °C with a rated lifetime of 5000 hours at +125 °C for this size, enabling sustained performance in elevated-temperature installations.
• Automotive-grade reliability — AEC-Q200 qualified for applications that require automotive-level dependability.
• Compact radial package — φ10 × 12.5 mm can with 5 mm lead spacing (±0.5 mm) and radial lead mounting for through-hole designs; available in bulk (no terminal forming) or bag packing.
• Standards and compliance — RoHS compliant.

Typical Applications

• Automotive electronics — Suitable for electronic modules where sustained high-temperature operation and long life are required.
• Power supply smoothing — Provides bulk capacitance and ripple handling for DC power rails in constrained radial-can footprints.
• Industrial controls — Applicable in control electronics exposed to elevated ambient temperatures and continuous loading.

Unique Advantages

• High-temperature capability: Rated −40 °C to +125 °C with 5000-hour endurance at +125 °C, enabling longer service life in hot environments.
• Automotive-grade qualification: AEC-Q200 rating supports use in designs that demand automotive-level reliability.
• Strong ripple performance: Specified ripple currents at both low and high frequencies (415.4 mA @120 Hz, 620 mA @100 kHz) help maintain stability under AC loading.
• Low impedance: 150 mΩ nominal impedance supports low-loss decoupling and energy delivery in power applications.
• Compact, through-hole form factor: φ10 × 12.5 mm radial can with 5 mm lead spacing simplifies placement in legacy and mixed-technology PCBs.
• Regulatory compliance: RoHS compliance reduces regulatory overhead for product rollouts.
