CL-90

The CL-90 is a 2-pin NTC Inrush Current Limiter features small physical size offers design-in benefits over larger passive components and solid state device for inrush current suppression. The disc thermistor with uninsulated lead wires. The problem of current surges in switch-mode power supplies is caused by the large filter capacitors used to smooth the ripple in the rectified 60Hz current prior to being chopped at a high frequency. The maximum surge current, the main purpose of limiting inrush current is to prevent components in series with the input to the DC/DC convertor from being damaged. The maximum steady-state current rating of a thermistor is mainly determined by the acceptable life of the final products for which the thermistor becomes a component. Suitable for PCB mounting.

• Low steady resistance and accompanying power loss
• Best-in-class capacitance ratings
• Excellent mechanical strength
• Energy surge at turn-on
• -50 to 175°C Wide operating temperature range
