SMT Current Sensors  
–
CST Series  
The CST surface mount current sensing transformers  
are designed for use from 50 kHz to nearly 1 MHz to  
sense continuous currents to 10 Amps and greater.  
The CST1 and CST2 differ in pinout numbering and layout  
in order to meet the requirements of different applications.  
These transformers feature extremely low primary DC  
resistance and 500 V isolation between windings. They  
are available in eight different turns ratios to meet a  
wide variety of requirements. They are ideal for use in  
switching power supply applications.

2. Inductance measured between secondary pins at 100 kHz, 0.1 Vrms.  
3. Primary current of 10 A causes approximately 25°C temperature rise  
above 25°C ambient. Higher current causes a greater temperature  
rise (see Temperature Rise vs Current curve).
