SMT current sense transformers up to 40A

March 17, 2015 // By Julien Happich
Coilcraft's CST2010 Series of current sense transformers detect switching current up to 40A over a frequency range of 50 to 500 kHz while also isolating circuits electrically, resulting in up to 10X lower power dissipation than current sense resistors, according to the manufacturer.

The compact, surface mount CST2010 Series has a 14.55x19.91mm footprint with a maximum height of 10.50mm. Coilcraft offers eleven turns ratios (primary-to-secondary) within the series ranging from 1:20 to 1:200.
The CST2010 Series also offers 500 Vrms isolation between windings and very low primary DC resistance (0.00036 Ohms). It features RoHS compliant tin-silver, over tin, over nickel, over phos bronze terminations and has an ambient temperature rating of -40°C to +125°C.
