Key Features

• Capacitance and Voltage: 180 µF rated at 25 V with ±20% tolerance, providing bulk energy storage for decoupling and filtering duties.
• Low ESR and High Ripple Current: ESR of 19 mΩ measured at 100 kHz; ripple current rating of 1.9 A at 100 kHz and 950 mA at 120 Hz, supporting high-frequency power stages and converters.
• High Temperature Capability: Operating temperature range from −55 °C to +150 °C with a guaranteed life of 2000 hours at 150 °C for sustained high-temperature operation.
• Automotive-Grade Reliability: AEC-Q200 qualified, meeting the series’ qualification for automotive applications where specified.
• SMD and Reflow-Compatible: Chip-type SMD construction with lead-free reflow soldering compatibility to a 260 °C peak, enabling modern assembly processes.
• Compact Package: Size dimension L: 1.2 cm × D: 0.8 cm with a surface-mount land recommendation of 8.3 mm × 8.3 mm for PCB layout.
• Regulatory Compliance: RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive Electronics: Suited for control modules and power subsystems that require components qualified to AEC-Q200 and capable of long-term operation at elevated temperatures.
• High-Temperature Power Systems: Bulk filtering and smoothing in power converters and supply rails that operate in environments up to 150 °C.
• Surface-Mount Assemblies: PCB designs and manufacturing processes that require lead-free reflow compatibility (260 °C peak) while retaining low ESR and high ripple performance.

Unique Advantages

• Extended High-Temperature Life: 2000 hours at 150 °C delivers predictable aging and service life for thermally demanding designs.
• Improved Power Handling: High ripple-current ratings and low ESR reduce heat generation and support higher current densities in compact assemblies.
• Automotive-Grade Qualification: AEC-Q200 qualification provides a documented level of reliability for vehicle electronics and other safety- and mission-critical systems.
• Assembly-Friendly SMD Form: Chip SMD construction and lead-free reflow compatibility simplify automated assembly while meeting modern environmental requirements.
• Compact Footprint: Small package dimensions and a defined land pattern (8.3 × 8.3 mm) help optimize PCB area for dense power electronics layouts.
