Murata Icon X Features

1.Rapid operation to protect the circuit in an overcurrent condition abnormality such as a short circuit.
   By removing the overcurrent condition, these products automatically return to the initial condition and can be used repeatedly.
2.Suitable for countermeasure to short circuit test in safety standard
3.Stable resistance after operation due to ceramic PTC
4.Similar size (0603 size) is possible due to the large capacity for electric power.
5.Possible to use these products as current limiting resistors with overcurrent protection functions
6.SMD type is helpful for miniaturizing circuits because of its small size and light weight
7.Lead is not contained in the terminations
