UBT1A331MPD

The UBT1A331MPD is a Nichicon UBT series aluminum electrolytic capacitor in a radial‑lead can, offering 330 µF capacitance at a 10 V rating. It is part of a high‑temperature series engineered for applications that require extended endurance at up to +125°C.

Designed for demanding environments, this polarized radial capacitor combines a compact φ10 × 12.5 mm can with AEC‑Q200 qualification and specified ripple and leakage characteristics to support reliable operation in automotive and other high‑temperature electronics.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with ±20% tolerance at 10 V rating, suitable for bulk energy storage and filtering in low‑voltage sections.
• High‑Temperature Endurance — Rated for operation from −40°C to +125°C and specified for 5000 hours of life at 125°C under the defined test conditions.
• Automotive‑Grade Qualification — AEC‑Q200 qualified, indicating suitability for automotive electronics and other applications requiring automotive reliability standards.
• Ripple Current Performance — Low‑frequency ripple current 415.4 mA at 120 Hz and high‑frequency ripple current 620 mA at 100 kHz to support circuits with steady and high‑frequency ripple demands.
• Leakage Current — Specified leakage current of 99 µA for stable performance after voltage application.
• Package & Mounting — Radial lead can, size φ10 × 12.5 mm, lead spacing 5 mm (±0.5 mm); available in bulk (no terminal forming) or bag packing.
• RoHS Compliant — Compliant with RoHS directive.

Typical Applications

• Automotive Electronics — Suited for automobile electronics where heavy‑duty, high‑temperature performance is required, supported by AEC‑Q200 qualification.
• High‑Temperature Power Modules — Use in power sections and modules that operate near +125°C and require stable capacitance and ripple handling over long life.
• Embedded Systems Exposed to Heat — Applicable where compact radial can capacitors are needed in thermally demanding environments.

Unique Advantages

• Extended 125°C Life: 5000 hours endurance at +125°C gives designers predictable long‑term behavior in hot operating environments.
• AEC‑Q200 Qualification: Explicit AEC‑Q200 rating supports use in automotive and similarly demanding applications that require component-level qualification.
• High Ripple Capability: Specified ripple currents of 415.4 mA (120 Hz) and 620 mA (100 kHz) enable reliable filtering under both low and high frequency ripple conditions.
• Compact Radial Can: φ10 × 12.5 mm package with 5 mm lead spacing offers a space‑efficient solution for through‑hole assemblies and retrofit designs.
• Controlled Leakage: Low leakage current (99 µA) supports stable performance after voltage application and reduces standby losses in sensitive circuits.
• RoHS Compliance: Environmentally compliant construction supports regulatory requirements for modern electronics manufacturing.
