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.

1. When ordering, please specify termination and packaging codes:

Typical Circuits

CSTX-125LC

Termination: L = RoHS compliant matte tin over nickel over phos bronze

Special order:

CST1

T = RoHS tin-silver-copper (95.5/4/0.5) or

S = non-RoHS tin-lead (63/37).

Packaging: C =7″ machine-ready reel. EIA-481 embossed plastic

(N turns)

B = Less than full reel. In tape, but not machine ready.

To have a leader and trailer added ($25 charge), use

code letter C instead.

D =13″ machine-ready reel. EIA-481 embossed plastic

tape (1000 parts per full reel).

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).

CST2

4. Terminating resistance (R ) value is based on 1 Volt output with

10 Amps flowing through the primary. Varying terminating resistance

increases or decreases output Voltage/Ampere according to the

5. Maximum volt-time product for the secondary.

6. Storage and operating temperature range -40°C to +125°C.

7. Electrical specifications at 25°C.
