Key Features

• Capacitance & Voltage — 220 µF capacitance rated at 100 V, suitable where higher energy storage and higher voltage handling are required.
• Temperature Range & Endurance — Operating range down to −55 °C up to +105 °C, with a rated lifetime of 5,000 hours at 105 °C for sustained high-temperature operation.
• Automotive-Grade Qualification — AEC-Q200 qualified, providing traceable reliability credentials for automotive electronic systems.
• Surface-Mount Chip Can Package — Radial, can-style SMD package engineered for surface mounting on high-density PCBs and compatible with automatic mounting machines fed by carrier tape.
• Ripple Current Performance — Specified ripple current: 440 mA at 120 Hz and 660 mA at 10 kHz, supporting filtering and smoothing tasks across common frequency ranges.
• Polarized Electrolytic — Polarized design with ±20% capacitance tolerance (at 120 Hz, 20 °C) for predictable electrical behavior in polarized circuits.
• RoHS Compliance — Conforms to RoHS directive (2011/65/EU, (EU)2015/863), meeting environmental substance restrictions.
• Compact Footprint — Package dimensions L: 1.65 × D: 1.8 cm with recommended surface-mount land size L: 1.83 × W: 1.83 cm for dense board layouts.

Typical Applications

• Automotive power electronics — Bulk smoothing and energy storage in vehicle power modules and control units where AEC-Q200 qualification and 100 V rating are required.
• DC–DC converters — Input/output filtering and bulk decoupling for converters demanding high capacitance and stable performance at elevated temperatures.
• Motor drive and powertrain control — Energy buffering and ripple attenuation in motor controllers and powertrain ECUs that operate across wide temperature ranges.

Unique Advantages

• High-capacitance in SMD form — Delivers 220 µF at 100 V in a chip-type can package, enabling designers to meet bulk energy requirements without large through-hole parts.
• Designed for automated assembly — Carrier-tape compatibility and surface-mount package streamline high-volume PCB assembly and reduce handling complexity.
• Long-term high-temperature reliability — 5,000-hour endurance at 105 °C supports sustained performance in thermally demanding environments.
• Automotive-grade assurance — AEC-Q200 qualification supports use in automotive systems where component qualification is a design requirement.
• Measured ripple handling — Specified ripple current ratings at both 120 Hz and 10 kHz help ensure predictable thermal and electrical performance across common operating frequencies.
• Regulatory compliance — RoHS conformity simplifies environmental compliance for assemblies and end products.
