Current Sensing Transformers
These low cost Coilcraft current sensing transformers
are designed for use up to 100 kHz. They incorporate
the current and sense windings in one small, encapsu-
lated package requiring minimum board space.
Varying the terminating resistance allows sensitivities of
1 to 100 Volts output per Ampere input.
Coilcraft current sensing transformers are designed to
provide 6 mm creepage/clearance between primary and
secondary windings
Applications include feedback control, overload sens-
ing, 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. Square wave response deteriorates above and below this frequency.
3. Varying terminating resistance increases or decreases output Voltage/Ampere according to the following equation: R_T = V_out × N_sec / I_in
4. Operating temperature range –40°C to +85°C.
5. Electrical specifications at 25°C.
