Murata Intros SMT Current Sense Xformers
Current-sense transformers.
Mansfield, MA — 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, and use UL94 V-0 package materials.

The three new series of current sense transformers are designed for the latest applications in high frequency equipment, have a frequency range of 50 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 ratings to 10A and between 20 and 200 turns, depending on the resolution of current measurement desired. A primary-to-secondary isolation of 500V rms in an industry-standard footprint helps simplify the transformers' use in 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 has a small footprint package style and provides 1200V rms primary-to-secondary isolation. The 5500 series is offered in a low profile package, with a primary-to-secondary isolation of 1000V rms. Free air operating temperature range for all of the transformers is -40 to +125°C.
