Inrush resistor S30814-Q791-A
)
The inrush resistor based on thick-film technology serves as a robust inrush current limiter. It is optimized for charging a 235 µF capacitor bank (configured as 2 × 470 µF in series) at voltages up to 750 V, as typically found in 400 V AC, three‑phase rectifier systems. Its design makes it well suited for demanding applications such as motor drives, switch‑mode power supplies (SMPS), and welding equipment.
