Key Features

• Electrical Rating — 100 µF capacitance at 63 V with ±20% tolerance, providing stable bulk capacitance for power filtering and decoupling.
• Low-Temperature ESR Specification — Added ESR specification after the −40°C test and an ESR of 250 mΩ measured at 100 kHz, supporting stable performance across frequency and temperature.
• Wide Operating Temperature — Specified for −40 °C to 125 °C operation, suitable for designs that must withstand elevated ambient temperatures.
• High-Temperature Endurance — 2000 hours at 125 °C endurance rating, with defined limits for capacitance change, tan δ, and leakage current after the test.
• Ripple Current Capability — Rated ripple currents of 200 mA at 120 Hz and 400 mA at 10 kHz, with frequency coefficients provided for other bands.
• Surface-Mount, Automated Assembly Ready — Packaged as an SMD radial/can type and applicable to automatic mounting machines fed with carrier tape for high-volume production.
• Reliability & Compliance — AEC-Q200 qualified and RoHS compliant (2011/65/EU,(EU)2015/863), documented for use in regulated and reliability-focused designs.
• Leakage Current Specification — Leakage defined as not more than 0.01CV (µA) after 2 minutes at 20 °C, enabling predictable standby behavior in power circuits.

Typical Applications

• Automotive Electronics — Bulk filtering and decoupling in vehicle electronic modules where AEC-Q200 qualification and operation to 125 °C are required.
• Surface-Mount Power Modules — Compact SMD can package and carrier-tape compatibility make this part suitable for power supply filtering in dense assemblies.
• High-Temperature Systems — Use in electronics that must maintain capacitance and controlled ESR after extended exposure to elevated temperatures.
• Automated Assembly Lines — Designed for automated placement from carrier tape, reducing assembly complexity in high-volume manufacturing.
