• High Temperature Range — Qualified for continuous operation from −40°C to +125°C, supporting designs that must survive extended elevated-temperature use.
• Endurance — Rated lifetime of 3000 hours at 125°C, enabling prolonged operation in high-temperature environments.
• ESR and Low-Temperature Performance — ESR specified at 150 mΩ measured at 100 kHz; ESR performance includes specification after −40°C test conditions.
• Ripple Current Capability — Rated ripple currents of 250 mA at 120 Hz and 500 mA at 10 kHz to support filtering and decoupling workloads.
• Package & Mounting — Surface-mount radial can (SMD) package sized approximately 1 × 1 cm with a recommended land size of 1.03 × 1.03 cm; compatible with automatic mounting machines fed by carrier tape.
• Qualification & Compliance — AEC-Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863), addressing regulated-environment and automotive program requirements.
• Polarized Device — Polarized aluminum electrolytic design for correct-oriented power applications.

Typical Applications

• Automotive electronic modules — Bulk filtering and decoupling in control units and modules that require AEC-Q200 qualification and operation to +125°C.
• Power supply filtering — Smoothing and ripple reduction in DC–DC converters and power rails at 25 V nominal systems, leveraging the specified ripple current ratings.
• High-temperature industrial electronics — Energy storage and decoupling in industrial controllers and power assemblies exposed to elevated ambient temperatures.
• Automated surface-mount production — Designed for tape-fed automated placement to streamline assembly for compact, high-density boards.

Unique Advantages

• High-temperature endurance: 3000 hours rated life at 125°C provides a quantifiable reliability metric for thermal stress conditions.
• Automotive qualification: AEC-Q200 status supports use in automotive programs where qualified components are required.
• Measured ESR after low-temperature testing: ESR specification includes performance following −40°C testing and is numerically specified at 150 mΩ (100 kHz), aiding design verification across temperature extremes.
• Designed for automated assembly: Carrier-tape compatibility and SMD can package reduce assembly complexity for high-volume manufacturing.
• Compact footprint with explicit land pattern: 1 × 1 cm body and recommended land size of 1.03 × 1.03 cm enable tight board layouts while preserving required solderability characteristics.
• Regulatory compliance: RoHS conformity provides compliance for regulated markets and programs.
