CST306-2A
Current Sense Transformers
High Frequency
:: C S T 2 0 6 / 3 0 6 D e s c r i p t i o n
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 effectively over the
frequency range of 20 kHz-200 kHz. They are constructed of UL rated
130ºC materials. Both models are available with a center tap option.

Technical Notes
1. Derate ET product by 32% for 50 kHz, 52% for 100 Hz and 50%
for unidirectional operation.
2. Rated primary current renders approximately 40ºC temperature rise.
3. CST206 models have maximum recommended terminating
resistance of 1 ohm per turn.
4. Primary is inserted through hole in casing.
5. 3 pin or center tapped (CT) models are designed with a T suffix.
