3D Model Datasheet

CST7030 Series

SMT Current Sense Transformers

Sensed current up to 20 Amps
Designed for use up to 1 MHz and above
Very low primary resistance
AEC-Q200 Grade 1 (−40°C to +125°C)
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.

メモ

When ordering, please specify packaging code: e.g.CST7030-150LC
Inductance measured between secondary pins at 100 kHz, 0.1 Vrms, 0 Adc.
Volt-time product is for the secondary, between pin 1 and 2.
For specific questions regarding frequency range, please contact us at [email protected].
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).
Terminating resistance (R_T) 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:
R_T (Ohms) = V_out × N_sec / I_in.
500 Vrms, 1 minute isolation (hipot) winding to winding.

終端処理:

RoHS compliant tin-silver-copper over tin over nickel over copper

パッケージ:

C = 7″ machine-ready reel. EIA-481 embossed plastic tape (600 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
B = Less than full reel. In an effort to simplify our part numbering system, Coilcraft is eliminating the need for multiple packaging codes. When ordering, simply change the last letter of your part number from B to C.
D = 13″ machine-ready reel. EIA-481 embossed plastic tape. Factory order only, not stocked (2500 parts per full reel).
