Key Features

• Core Technology Conductive polymer hybrid aluminum electrolytic construction delivering stability, low ESR and high ripple-current handling.
• Capacitance & Voltage 120 µF nominal capacitance with a 50 V rated voltage and ±20% tolerance at 120 Hz, 20 °C.
• High Temperature Endurance Rated for operation from −55 °C to 135 °C with a rated lifetime of 4000 hours at 135 °C for the specified conditions.
• Low ESR & Ripple Capacity ESR of 28 mΩ at 100 kHz (20 °C) and ripple-current ratings of 1.6 A at 100 kHz and 240 mA at 120 Hz support high-frequency decoupling and power-stage filtering.
• Package & Mounting Surface-mount radial/can SMD package with compact dimensions (L: 1 × D: 1 cm) and a recommended land size of 1.03 × 1.03 cm for PCB placement.
• Automotive-Grade Qualification AEC-Q200 qualified and RoHS compliant for use in regulated environments and automotive electronic assemblies.

Typical Applications

• Automotive electronics — Power decoupling and filtering in modules that require AEC-Q200 qualification and reliable performance at temperatures up to 135 °C.
• High-temperature power electronics — Bulk and local energy storage where sustained ripple handling and low ESR are required under thermal stress.
• Surface-mount power module designs — Compact SMD can package suited to space-constrained boards needing robust decoupling and long-term endurance.

Unique Advantages

• High-temperature endurance: 4000 hours rated life at 135 °C provides documented longevity for designs exposed to elevated ambient or operating temperatures.
• Low ESR at high frequency: 28 mΩ ESR at 100 kHz supports efficient high-frequency filtering and reduces heat generation in power stages.
• Strong ripple handling: 1.6 A ripple current at 100 kHz enables use in high-frequency converters and switching regulators.
• Automotive-grade reliability: AEC-Q200 qualification aligns the component with automotive electronics design and manufacturing requirements.
• Compact SMD can package: Small 1 cm × 1 cm footprint helps reduce BOM size while maintaining electrolytic capacitance values.
• Regulatory compliance: RoHS compliant per 2011/65/EU and (EU)2015/863 for restricted substances.
