• Wide Temperature Range — Rated for operation from -55 °C to +105 °C, with impedance stability across temperature as specified in the series datasheet.
• Surface-Mount Package — Radial, can-style SMD package with dimensions L: 6 mm × D: 6.3 mm and a recommended land size of 6.6 mm × 6.6 mm for compact PCB layouts.
• Assembly Compatibility — Lead-free reflow soldering compatibility up to peak conditions stated in the product series specification for standard SMD assembly processes.
• Environmental Compliance — RoHS compliant, meeting current restrictions on hazardous substances.

Typical Applications

• Automotive power supplies — Low ESR and high ripple-current capability make this capacitor suitable for smoothing and decoupling in on-board power systems.
• Engine control and ECU modules — AEC-Q200 qualification and 2000 h life at 105 °C support use in temperature-stressed control electronics.
• Infotainment and telematics — Compact surface-mount footprint and stable performance over -55 °C to 105 °C help maintain power integrity in cabin electronics and communication modules.

Unique Advantages

• Low ESR for tighter regulation: 25 mΩ ESR at 100 kHz reduces voltage ripple and improves regulator stability in power-dense designs.
• High ripple-current handling: Rated ripple currents of 2.53 A (100 kHz) and 1.265 A (120 Hz) allow the capacitor to absorb transient loads and reduce heating.
• Automotive-qualified endurance: AEC-Q200 qualification plus a 2000 hour life at 105 °C provide traceable reliability for automotive programs.
• Compact SMD form factor: Small 6.0 × 6.3 mm package and 6.6 × 6.6 mm recommended land pattern save board space in dense layouts.
• Wide operating temperature: −55 °C to +105 °C rating maintains performance across harsh thermal environments.
• RoHS compliance: Conforms to current environmental regulations for hazardous substances.
