FC-ULCT1013-1:200-35A

FANGCHENG · Current Sense Transformers · DIP-4

FC-ULCT1013-1:200-35A from FANGCHENG, in a DIP-4. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 SEC_1 passive Secondary winding (N turns, 200 turns for 1:200) terminal; secondary inductance measured across pins 1-2 is 20.0 mH min, DCR 6000 mOhm max.
2 SEC_2 passive Secondary winding (N turns) opposite terminal to pin 1; connects to burden resistor RT with pin 1, DCR 6000 mOhm max.
3 PRI_3 passive Primary winding (1 turn) terminal; primary current rating up to 35A, DCR 0.8 mOhm max measured across pins 4-3.
4 PRI_4 passive Primary winding (1 turn) terminal opposite pin 3 where input current Iin flows; up to 35A, DCR 0.8 mOhm max across 4-3.
