CST306-3T

Description:

Designed for switching power supply applications, Triad current sense

transformers are used to detect the current passing through a conductor.

These transformers are very reliable and operate over the frequency range of

20 kHz-200 kHz.

Electrical Specifications (@25C)

Safety:

These current sense transformers are constructed of UL rated 130°C materials.

Dimensions:

.180

Units: In inches

Technical Notes:

products meet the requirements of 2002/95/EC, known as the RoHS initiative.
