The 397UVR2R5MEW is an aluminum polymer capacitor designed for high ripple current applications such as DC-DC converters and voltage regulators. It operates within a temperature range of -55°C to +105°C and has a rated voltage of 2.5 VDC with a capacitance of 390 µF. The part features a low ESR of 0.5101 Ω at 100 kHz and 20°C, and a maximum ripple current of 3390 mA at 105°C. It is mounted in a 6.3 mm diameter by 6 mm length cylindrical case. Specifications include a capacitance tolerance of +20% at 120 Hz, a dissipation factor of 12% maximum, and leakage current of 280 µA maximum. The unit meets load life and damp heat test requirements, with all performance parameters within defined limits after testing. It is compatible with reflow soldering conditions of 230°C for 75 seconds.
