The 380LQ271M400K022 is a Type 380LQ compact, high-capacitance aluminum electrolytic snap-in capacitor designed for 400 Vdc applications with a 450 Vdc surge rating. This capacitor features a 270 µF capacitance with ±20% tolerance and operates reliably across a temperature range of -25°C to +85°C. The unit exhibits a maximum ESR of 0.737 ohms at 120 Hz and 0.368 ohms at 20 kHz (both at +25°C), with ripple current ratings of 1.67 A at 120 Hz and 2.34 A at 20 kHz when operating at +85°C. The compact design with a nominal size of 30 mm diameter by 30 mm length enables space-efficient integration into power supply circuits, energy storage systems, and industrial equipment where high capacitance density and thermal stability are essential.
