Coilcraft, Inc. High Frequency Current Sense Transformers CS4100V-01L

The CS4100V-01L is a high-frequency current sense transformer designed for use up to 1 MHz, with a 1:100 turns ratio and a secondary inductance of 20 mH measured at 15.75 kHz. It has a maximum primary DCR of 1.4 ohms, supports a secondary volt-time product of 298 Vµsec, and is rated for a maximum sensed current of 35 A with a terminating resistance of 2.9 ohms to produce a 1 V output. The transformer provides 3750 Vrms isolation between windings and meets UL/CSA/IEC 60950 Reinforced Insulation requirements with 3 mm creepage and clearance. It is encapsulated, weighs 8.8 to 9.3 grams, and uses tin-silver over copper terminations. Packaging is sold in tubes of 29 units.
