• Low Impedance  170 mΩ impedance (specified) to support effective filtering and decoupling on power rails.
• High-Temperature Assembly  Compatible with 260°C peak reflow soldering; recommended reflow condition: 260°C peak for 5 seconds and 230°C over 60 seconds (two cycles; φ10 × 10: one cycle).
• Temperature & Endurance  Operates from −55°C to +105°C with a rated lifetime of 5000 hours at 105°C.
• Ripple Current Capability  Handles 225 mA at 120 Hz and 450 mA at 10 kHz, supporting both low- and high-frequency ripple requirements.
• Package & Mounting  Radial can SMD package designed for surface mounting on high-density PCBs; compatible with automatic mounting machines fed with carrier tape. Recommended PCB land size: 8.3 × 8.3 mm.
• Regulatory & Quality  Compliant with the RoHS directive and AEC-Q200 qualified.

Typical Applications

• Automotive power filtering  AEC-Q200 qualification and low impedance make the capacitor suitable for vehicle power modules and rail decoupling where elevated operating temperatures and vibration tolerance are required.
• DC–DC converter output smoothing  220 µF at 25 V combined with 170 mΩ impedance and high-frequency ripple current capability supports stable output filtering and transient handling.
• Industrial power electronics  With a −55°C to +105°C operating range and 5000-hour endurance at 105°C, the part is applicable to control and power boards that require long-term stability at elevated temperatures.
• High-density surface-mount assemblies  Chip-style SMD can and compatibility with automatic carrier-tape mounting simplify placement on compact PCBs used in embedded systems.

Unique Advantages

• Reflow-ready for modern assembly: Designed to withstand 260°C peak reflow profiles, enabling compatibility with high-temperature soldering processes.
• Long-term high-temperature reliability: Rated for 5000 hours at 105°C, providing predictable aging behavior for sustained high-temperature operation.
• Low-impedance performance: 170 mΩ impedance and strong ripple current ratings reduce voltage ripple and improve regulator stability in power designs.
• SMD form factor for dense layouts: Compact radial can SMD package and a prescribed land pattern (8.3 × 8.3 mm) facilitate placement on space-constrained PCBs.
• Industry compliance: RoHS conformity and AEC-Q200 qualification support use in regulated and quality-focused development environments.
• Assembly automation compatibility: Built for use with automatic mounting machines fed by carrier tape, streamlining high-volume production.
