I'm looking at making an inrush current limiter based on a series resistors and a relay across the resistor that shorts the relay when the inrush current has passed. The relay coil is across the load. During inrush, the resistor drops the load voltage below the relay pull in voltage. After the inrush, the resistor drops less voltage allowing the relay to pull in. So, I'm trying to determine the resistor characteristics. Resistance, power rating, and surge power rating. Does anyone know of any application notes about this? Thanks!
