Pulse Protective Resistor

The Pulse Protection Resistor (PPR Series) boasts a rated power range of 0.25W to 2W and a resistance span from 2.2 ohms to 4.7M ohms. It is resistant to the "sintering effect" caused by high surges, which would otherwise drastically reduce its resistance value. Furthermore, it features a shape-retaining, multilayer, non-flammable coating. This offers superior performance in all aspects compared to carbon composition resistors. Consequently, it serves as a viable replacement for carbon composition resistors such as those from KOA/HPC.
