The 405K100CB4G-FA is a surface-mount metallized polyester film capacitor designed for high-frequency switching power supplies. It has a capacitance of 4.0 µF, a DC voltage rating of 100 V, and a maximum ESR of 0.007 Ω at 500 kHz. The component measures 12.7 mm in width, 6.3 mm in thickness, and 11.4 mm in length, with a gull-wing lead configuration and 3 leads per side. It operates from -55 °C to +125 °C and is fully RoHS compliant with a tin leadframe finish suitable for lead-free soldering up to 220 °C. The capacitor supports pick-and-place assembly and meets MIL-STD-202 for vibration and IPC/J-STD-20 for moisture sensitivity level 4. Its dissipation factor is ≤1.0% at 1 kHz and +25 °C, and it exhibits a maximum RMS current of 11.5 A at 500 kHz and +85 °C.
