Murata Releases Three New Series Of Surface Mount Current Sense Transformers

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.

Designed to measure ac currents up to 10A, the 5300 series comprises ten different devices with a primary current rating to 10A and between 20 and 200 turns, depending on the resolution of current measurement desired. A primary to secondary isolation of 500Vrms in an industry-standard footprint helps simplify their inclusion into existing product designs.

The 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 -40 to +125°C.
