• High Ripple Current Capacity — Low-frequency ripple current 450 mA (120 Hz) and high-frequency ripple current 3.0 A (100 kHz) for robust smoothing under dynamic loads.
• Dielectric Loss (tan δ) — tanδ = 0.1 measured at 20 °C, 120 Hz, 50 V, supporting predictable dissipation characteristics.
• Leakage Current — Rated leakage current of 90 µA.
• Long Life at Elevated Temperature — Endurance of 4000 hours at 125 °C with specified post-test limits for capacitance, tanδ and ESR.
• Temperature Range — Operational from -55 °C to +125 °C for wide‑range environmental use.
• Package & Mounting — Compact can-style SMD (φ10 × 12.5 mm length); surface-mount, radial can - SMD package with embossed carrier taping for automated assembly.
• Automotive-Grade Qualification — AEC-Q200 rated for applications requiring recognized automotive stress screening.
• RoHS Compliant — Meets RoHS directive requirements.

Typical Applications

• Automotive Electronics — Smoothing and decoupling on 50 V board rails in automotive control modules where AEC‑Q200 qualification and extended temperature range matter.
• Board-Level Power Filtering — Bulk decoupling and ripple suppression in compact SMD power systems that require low ESR and high ripple handling.
• Power Module Support — Local energy storage and transient support for DC‑DC converters and power regulators on constrained PCB layouts.

Unique Advantages

• High ripple tolerance: Combined low ESR (18 mΩ at 100 kHz) and 3.0 A HF ripple capability reduce heating and improve AC stability under dynamic loads.
• Extended high-temperature endurance: 4000‑hour life at 125 °C supports designs requiring sustained operation at elevated temperatures.
• Automotive-grade reliability: AEC‑Q200 rating aligns the part with automotive system requirements for stress and reliability.
• Compact SMD form factor: φ10 × 12.5 mm can-style SMD package with embossed carrier taping simplifies automated placement while minimizing board footprint.
• Predictable dissipation: Specified tanδ (0.1 at 20 °C, 120 Hz, 50 V) and defined leakage current enable predictable thermal and leakage budgeting in designs.
• Regulatory compliance: RoHS compliance helps streamline materials compliance for global electronics programs.
