UBH1E271MNS1GS

The UBH1E271MNS1GS is a chip-type aluminum electrolytic capacitor engineered for high-temperature, vibration-prone environments. It delivers 270 μF capacitance at a 25 V rating in a compact surface-mount radial can package designed for robust end-of-life performance.

Targeted use cases include automotive electronics and other high-temperature systems that require long life, low temperature ESR and proven reliability; the part carries AEC-Q200 qualification and RoHS compliance to support those markets.

Key Features

• Electrical Performance — 270 μF nominal capacitance with ±20% tolerance and a 25 V rated voltage for bulk decoupling and energy storage in compact assemblies.
• Low Temperature ESR — Specified ESR of 150 mΩ at 100 kHz to support stable low-temperature performance and improved ripple handling.
• High Temperature Endurance — Rated operating range from −40°C to +150°C with a load-life specification of up to 2000 hours at +150°C, supporting long-term operation in elevated ambient conditions.
• Reliability & Qualification — AEC-Q200 qualified and RoHS compliant, demonstrating suitability for demanding, regulated applications.
• Vibration Resistance — Chip-type construction with vibration resistance characteristics suitable for mechanically stressed environments.
• Package & Mounting — Surface-mount radial can (SMD) chip package with compact dimensions (approximately 1 cm × 1 cm) and surface-mount land recommendations for PCB integration.
• Ripple Current Capability — Rated ripple current values include 80.4 mA at 120 Hz and 120 mA at 10 kHz, with frequency coefficients documented in the product data.

Typical Applications

• Automotive Electronics — For vehicle systems requiring AEC-Q200 qualification, vibration resistance and sustained operation at elevated temperatures.
• High-Temperature Power Circuits — Bulk decoupling and filtering in electronics that must withstand up to +150°C and maintain low ESR across temperature.
• Harsh-Environment Embedded Systems — Power conditioning in equipment exposed to mechanical vibration and wide temperature swings.

Unique Advantages

• Long High-Temperature Life: Up to 2000 hours at +150°C provides predictable ageing behavior and end-of-life characteristics for high-temperature designs.
• Verified Automotive Qualification: AEC-Q200 rating reduces qualification effort for automotive subsystems and other regulated applications.
• Low-Temperature ESR Performance: 150 mΩ (100 kHz) specification helps maintain effective filtering and ripple attenuation across temperature extremes.
• Compact SMD Can Package: Chip-type radial can in a ~1 cm × 1 cm footprint enables space-saving board layouts while retaining electrolytic capacitance density.
• Regulatory Compliance: RoHS compliance supports deployment in markets requiring restricted-substance conformance.
