The ASMD1210-050 with PTC Resettable Fuses 1210 RoHS is a type of electronic part manufactured by JDT. It is a polymeric resettable PTC fuse which helps to protect against overcurrent and short-circuit, especially when used in electronic circuits. The ASMD1210-050 features a 1210 case size, and comes in a variety of current ratings ranging from 0.05 A to 5 A. Additionally, it is RoHS compliant and comes with a high release temperature of 121 °C. It is designed with thermistor-disc technology and has a self-resetting feature, meaning it can cycle back to its original state after a fault. The ASMD1210-050 has four distinct characteristics of a self-resetting thermal fuse – namely, low trip current, low voltage drop, easy installation, and corrosion resistance.
