Current Sensors – D18xx, CS1xxx
These sensors function as the secondaries of a current
transformer.The conductor carrying the current to be mea-
sured is the “one turn primary.” Voltage per Ampere can be
adjusted by varying the terminating resistor (see note 3).
Applications include sensing branch circuit overload,
switcher feedback, and detecting load drop or shutdown.
They come in a molded version (CS1xxx Series) or en-
capsulated model (D18xx Series).
Coilcraft Designer’s Kit P403 contains samples of
the CS1050, CS1100 and CS1200 sensors, current
transformer versions with equivalent ratings, plus two
50/60 Hz current sensors. To order, contact Coilcraft or

1. Inductance is measured at 1 kHz, 0.05 Vrms.
2. Volt-time product is based on 2000 Gauss.
3. Terminating resistance (R_T) value is based on 1 Volt output with 35 Amps flowing through the primary. Varying terminating resistance increases or
decreases output Voltage/Ampere according to the following equation: R_T = V_out × N_sec / I_in
4. Ambient temperature range –40°C to +85°C.
5. Electrical specifications at 25°C.
