Current Sense Transformers
These low cost Coilcraft current sensing transformers
are designed for use up to 1 MHz. They incorporate the
current and sense windings in one small, encapsulated
package requiring minimum board space.
Coilcraft current sensing transformers are designed to
meet UL/CSA/IEC 60950 Reinforced Insulation specifi-
cation and provide 3 mm creepage/clearance between
primary and secondary windings. Winding to winding
isolation (hipot) is 3750 Vrms, tested for one minute.
Applications include feedback control, overload sensing,
detecting load drop or shutdown, and proportional output.
Coilcraft Designer’s Kit P403 contains the three stan-
dard current sensing transformers, sensor-only versions
of each, plus two 50/60Hz current sensors. To order,

1. Inductance is for the secondary, measured at 15.75 kHz, 1 Vrms.
2. Volt-time product is for the secondary, 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
