Current Sense Transformers CST7030
• AEC-Q200 Grade 1 qualified (–40°C to +125°C ambient)
• Small surface mount current sensors
• Sensed current up to 20 A; Frequency range up to 1 MHz
• Very low primary DC resistance
• 500 Vrms, one minute isolation (hipot) between windings
• Designed for:
Continuous AC current monitoring in switched-mode power
supply; Overload and short-circuit protection; Current
measurement in traction motor and battery management
systems in conventional and xEV (EV, HEV, FCEV) vehicles.
• Can also be used in 48 V vehicle electrical systems

1. When ordering, please specify packaging code:
CST7030-150LC
Packaging: C = 7machine-ready reel. EIA-481 embossed plastic
tape (600 parts per full reel).
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 = 13machine-ready reel. EIA-481 embossed plastic
tape. Factory order only, not stocked (2500 parts per
full reel).
2. Inductance measured between secondary pins at 100 kHz, 0.1 Vrms,
0 Adc.
3. Maximum volt-time product is for the secondary, based on 2000 Gauss.
4. Primary current of 20 A causes less than 25°C temperature rise from
25°C ambient. Higher current causes a greater temperature rise (see
Temperature Rise vs Current curve).
5. Terminating resistance (RT) value is based on 1 Volt output with 20 Amps
flowing through the primary. Varying terminating resistance increases or
decreases output Voltage/Ampere according to the following equation:
RT = Vout × Nsec/Iin.
6 Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
