Description
The CAK36F-50-18000-K-FE4-E is a flange-mounted hermetically sealed high-energy composite tantalum electrolytic capacitor rated at 50 V and 18000 µF with tolerance code K (+/-10%). The rated voltage is derated to 30 V for high-temperature operation, with a surge voltage of 55 V. Key electrical limits include tanδ of 70% max at 100 Hz, ESR of 0.04 Ω max at 1 kHz, DC leakage current of 400 uA max at 25degC and 3200 / 4000 uA max at 125degC/150degC, and impedance of 1.5 Ω max at 100 Hz. Capacitance change is -60 / +60 / +70% 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.
