UBT1E331MPD

The UBT1E331MPD is a radial-lead aluminum electrolytic capacitor designed for high-temperature operation and demanding load-life conditions. It provides 330 µF capacitance at a 25 V rating in a compact φ10×16 mm can with 5 mm lead spacing, making it suitable for applications that require stable energy storage and ripple handling at elevated temperatures.

Engineered for applications requiring extended endurance at +125 °C, this part combines high ripple-current capability, low leakage, and AEC‑Q200 qualification to address robust system-level reliability requirements.

Key Features

• Capacitance & Tolerance — 330 µF nominal capacitance with a tolerance of ±20% (120 Hz, 20 °C), providing predictable bulk energy storage for smoothing and decoupling tasks.
• Rated Voltage — 25 V working voltage suitable for 25 V system rails and power domains.
• High-Temperature Endurance — Rated for operation from −40 °C to +125 °C with a specified lifetime of 5000 hours at 125 °C, supporting sustained performance in hot environments.
• Ripple Current Capability — Low-frequency ripple current 633.15 mA (120 Hz) and high-frequency ripple current 945 mA (100 kHz), enabling effective filtering under both low- and high-frequency stress.
• Low Leakage — Leakage current specified at 247.5 µA, reducing quiescent losses and improving standby behavior in power-sensitive circuits.
• Mechanical & Mounting — Radial-lead can package (φ10×16 mm) with 5 mm lead spacing (±0.5 mm), provided in bulk/bag packing for through-hole assembly and manual or wave-process insertion.
• Automotive-Grade Reliability — AEC‑Q200 qualified and RoHS compliant, reflecting suitability for electronics where qualified components are required.

Typical Applications

• Automotive Electronics — Suited for automobile electronics and other heavy-duty systems that require operation at elevated temperatures and AEC‑Q200 qualification.
• High-Temperature Power Modules — Used where sustained performance at up to +125 °C is required for bulk energy storage and smoothing under thermal stress.
• 25 V Power Rails — Applied on 25 V system rails for bulk filtering and ripple suppression, leveraging its 330 µF capacitance and defined ripple-current ratings.

Unique Advantages

• High thermal endurance: 5000 hours at +125 °C supports long-term operation in elevated-temperature environments.
• Qualified reliability: AEC‑Q200 qualification aligns the component with automotive and other demanding reliability programs.
