Description
The CAK36F-35-45000-K-FE7-E is a flange-mounted hermetically sealed high-energy composite tantalum electrolytic capacitor rated at 35 V and 45000 µF with tolerance code K (+/-10%). The rated voltage is derated to 21 V for high-temperature operation, with a surge voltage of 38.5 V. Key electrical limits include tanδ of 100% max at 100 Hz, ESR of 0.05 Ω max at 1 kHz, DC leakage current of 600 uA max at 25degC and 4800 / 6000 uA max at 125degC/150degC, and impedance of 2.5 Ω max at 100 Hz. Capacitance change is -75 / +80 / +85% at -55degC and +60%/+70% at 125degC/150degC. The device operates from -55degC to +150degC, with voltage derating required above +85degC, and conforms to GJB733B-2011 and Q/TCPC2002-2024.
