This part is optimized for environments up to +125°C and is AEC-Q200 qualified and RoHS compliant, making it suitable for demanding electronic modules and automotive electronics where long-term reliability at elevated temperatures is required.

Key Features

• Electrical Capacity and Voltage: 220 µF nominal capacitance with a 10 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Ripple Current Performance: Rated ripple current of 227.8 mA at 120 Hz and 340 mA at 100 kHz, providing measurable AC load handling across low and high frequencies.
• Low Leakage: Specified leakage current of 66 µA, supporting low-standby-loss designs.
• Impedance: Impedance of 260 mΩ for predictable ESR-related behavior in power applications.
• High-Temperature Endurance: Rated life of 2000 hours at +125°C for the φ8 package, supporting heavy-duty, high-temperature operation.
• Wide Operating Temperature: −40°C to +125°C operating range for use in extreme thermal conditions.
• Mechanical / Package: Radial lead can (φ8 × 11.5L) with 3.5 mm lead spacing (±0.5 mm), available in bulk or bag packing for through-hole assembly.
• Automotive-Grade Qualification & Compliance: AEC-Q200 qualified and RoHS compliant, aligning with automotive and high-reliability program requirements.
• Production Status: Mass production availability for consistent supply and procurement planning.

Typical Applications

• Automotive Electronics — Designed for automotive modules that require components qualified to AEC-Q200 and able to withstand +125°C operating and endurance conditions.
• High-Temperature Electronic Modules — Suitable for power and control electronics that operate in elevated-temperature environments due to its 2000 h endurance at +125°C.
• Through-Hole / Radial-Mount Assemblies — Compact φ8 radial can with 3.5 mm lead spacing supports conventional through-hole mounting and hand or wave-soldered assemblies.

Unique Advantages

• Proven High-Temperature Endurance: 2000 hours at +125°C (φ8) provides verifiable lifetime behavior under sustained high-temperature and DC-bias ripple conditions.
• Automotive-Grade Assurance: AEC-Q200 qualification indicates suitability for demanding, reliability-focused applications where industry-standard qualification is required.
• Measurable Ripple Handling: Specified ripple currents at both 120 Hz and 100 kHz let designers assess AC stress across frequency ranges and size systems accordingly.
• Compact Radial Form Factor: φ8 × 11.5 mm can with 3.5 mm lead spacing minimizes board area while remaining easy to implement in through-hole assemblies.
• Low Leakage and Known Impedance: 66 µA leakage and 260 mΩ impedance enable predictable power-loss and thermal budgeting in system designs.
• Production-Ready Supply: Mass production status and standard bulk/bag packing help simplify procurement and assembly planning.
