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 very low 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 tempera-

ture rise (see Temperature Rise vs Current curve).

4. Terminating resistor value is based on 1 Volt output with 10 Amps

flowing through the primary. To determine the value for other input

currents, refer to the schematic and use the following formula:
