SMT CURRENT SENSE TRANSFORMERS

Product Name:

SMT CURRENT SENSE TRANSFORMERS

Product Description

SMT CURRENT SENSE TRANSFORMERS

SMTEE4.4 SERIES

Features :

．Very low DC resistance

．Different turns ratios

．Very small package

．RoHS compliant and halogen free

．500Vrms,one minute isolation(hipot) between windings

．Sensed Current – primary rated for 7 Amps.

Characteristics :

Primary current of 7 A causes less than 35°C temperature rise from 25°C ambient. Higher current causes a greater temperature rise

Operating temperature : -40℃ to 125℃.

Storage temperature Component: –40°C to +165°C

Inductance measured between secondary pins at 100 kHz, 0.1 Vrms, 0 Adc.

Applications :

Switching power supplies

Feedback control

Overload sensing.

Load drop/shut down detection
