Current sense transformers designed for latest applications in high frequency equipment
Murata Power Solutions has introduced three new ranges of surface-mount current sense transformers. The 5300, 5400 and 5500 series can be used to measure or monitor AC currents in high frequency applications such as switched-mode power supplies, motor controllers, and electronic lighting ballasts. All three series are RoHS compliant, feature UL94 V-0 package materials, have a frequency range of 50kHz to 500kHz and comply with the J-STD-020C standard for reflow soldering.
DesiThe 5400 and 5500 series are designed to measure AC currents up to 15A and are available with 50, 100 or 200 turns. The 5400 series features a small footprint package style and provides 1200Vrms primary to secondary isolation. The 5500 series is offered in a low profile package, with a primary to secondary isolation of 1000Vrms. Free air operating temperature range for all three series is -40ºC to +125ºC.
