Per reel) *1 Shows the Maximum Current value which Shall be passed repeatedly when the circuit runs abnormally. *2 Shows the Maximum Current value which Shall be passed continuously without tripping at 25C and 60C *3 Shows the Trip Current value when Posistor shall protect circuit from over load at 25C and -10C *4 This rated value is a value when the thermal dissipation coefficient of a mounting state is 10mW/C. In other condition of 10mW/C, rated values may be different. This information may be changed without a previous notice. Murata Manufacturing Co., Ltd. 3.
