Coilcraft highlights SMT current sense transformers at APEC
This week at APEC in North Carolina, Coilcraft has announced that it is launching the CST2010 series of current sense transformers in Booth 1107. The devices detect switching current up to 40A over a frequency range of 50-500kHz while also isolating circuits electrically, resulting in up to ten times lower power dissipation than current sense resistors.
This makes them suited for use in SMPS applications, including feedback control, overload detection and load drop/shut down detection.
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 500Vrms isolation between windings and very low primary DC resistance (0.00036Ω). It features RoHS compliant tin-silver, over tin, over nickel, over phos bronze terminations and has an ambient temperature rating from -40 to +125°C.
n addition to the CST2010 series, Coilcraft will also be featuring a number of other products at APEC 2015, including its expanding line of flyback and planar transformers for PoE applications, its XAL/XFL family of high-performance moulded power inductors and its broad range of AEC-Q200 qualified magnetics for automotive applications.
As with all Coilcraft parts, free evaluation samples are available online.
