• Low Impedance Performance — Chip‑type, low‑impedance construction optimized for reduced AC loss; specified tangent of loss angle (tanδ) of 0.22 at 20°C, 120 Hz for this part.
• High Ripple Current Capability — Rated low‑frequency ripple current of 1.32 A at 120 Hz and high‑frequency ripple current of 2.64 A at 10 kHz, enabling effective smoothing of power rails under dynamic loads.
• Thermal Endurance — Operates from −55°C to +105°C with an endurance rating of 5000 hours at 105°C, supporting long‑term reliability in elevated‑temperature environments.
• Leakage & Dissipation — Specified leakage current of 1275 µA and dissipation characteristics defined by tanδ measurement at 20°C, 120 Hz to assist in thermal and loss budgeting.
• Packaging & Assembly — Surface‑mount, radial can (SMD) package, size φ18 × 21.5 mm (L: 2.15 × D: 1.8 cm) with embossed carrier taping for automated placement; recommended land size L: 1.83 × W: 1.83 cm.
• Automotive Grade — AEC‑Q200 qualified and RoHS compliant, making it suitable for applications that require recognized automotive component qualification and environmental compliance.

Typical Applications

• Automotive electronic modules — Suitable for automotive systems where AEC‑Q200 qualification and extended temperature endurance are required.
• High‑temperature power electronics — Bulk capacitance and 5000‑hour endurance at 105°C support power conditioning in elevated‑temperature environments.
• Automated surface‑mount production — Embossed carrier taping and chip‑type SMD can package facilitate reliable placement on automated assembly lines.
• Ripple current management — Specified low‑ and high‑frequency ripple current ratings support smoothing and decoupling of dynamic power rails.

Unique Advantages

• High bulk capacitance in an SMD package: 5100 µF at 25 V delivers substantial energy storage while conserving board area compared with larger through‑hole parts.
• Designed for elevated‑temperature operation: Rated to +105°C with a 5000‑hour endurance specification, reducing the need for over‑specifying thermal margin in many designs.
• Measurable ripple handling: Defined ripple current ratings at 120 Hz and 10 kHz enable designers to size capacitors against real AC stress conditions.
• Automotive readiness: AEC‑Q200 qualification and RoHS compliance provide supply‑chain confidence for vehicle electronics programs.
• Assembly‑friendly packaging: Embossed carrier taping and surface‑mount can format streamline pick‑and‑place integration in high‑volume manufacturing.
