• High Ripple Current Capability — Supports 425 mA at 120 Hz (low frequency) and 850 mA at 10 kHz (high frequency), enabling effective ripple suppression across frequency ranges.
• Wide Temperature & Long Life — Rated for −55 °C to +105 °C with 5,000 hours endurance at 105 °C, suitable for prolonged operation in elevated temperatures.
• Automotive Grade Reliability — AEC‑Q200 qualified and vibration resistant, supporting demanding reliability requirements for vehicle electronics.
• Surface Mount Package — φ10 × 10L radial can, surface mount (can‑SMD) package with recommended land size L: 1.03 × W: 1.03 cm and supplied in embossed carrier taping for automated assembly.
• Leakage & Loss Characteristics — Specified leakage current of 117.5 µA and DF (tan δ) measured at industry standard conditions to aid predictable power‑system behavior.
• Regulatory Compliance — RoHS compliant, supporting environmental compliance requirements.

Typical Applications

• Automotive power systems — Bulk filtering and smoothing on vehicle power rails where AEC‑Q200 qualification and wide temperature range are required.
• Automotive power modules — Decoupling and ripple suppression in DC‑DC converters and power module outputs, leveraging high ripple current capability.
• Rugged on‑board electronics — Use in vibration‑resistant, high‑density SMD assemblies that demand long endurance at elevated temperatures.

Unique Advantages

• High ripple tolerance: Specified low‑ and high‑frequency ripple currents (425 mA at 120 Hz, 850 mA at 10 kHz) support robust filtering across a broad frequency range.
• Long endurance at elevated temperature: 5,000 hours rated life at 105 °C provides predictable long‑term performance in hot operating environments.
• Automotive qualification: AEC‑Q200 rating and vibration resistance address the reliability needs of automotive electronics designs.
• Compact SMD form factor: φ10 × 10L chip can and embossed carrier taping enable automated placement on high‑density PCBs, reducing assembly complexity.
• Predictable electrical behavior: Defined tan δ (0.14 at 20 °C, 120 Hz), leakage current, and ±20% capacitance tolerance simplify design margining and system modeling.
• RoHS compliance: Meets environmental directives for restricted substances.
