Current Sense Transformers Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to confirm exact electrical tolerances and packaging configuration. Ensure the selected variant matches the required inductance value of 180 uH and current rating of 20 A for the target application. Cross-reference the package dimensions and pinout with the PCB footprint to guarantee mechanical compatibility during assembly.

Current Sense Transformers Selection Notes

Select this component when high-frequency current isolation is required in space-constrained designs. The 1:30 turns ratio provides appropriate signal scaling for downstream amplification or ADC interfaces. Consider the 180 uH primary inductance for ripple current filtering requirements. Evaluate the thermal performance at +125 C if the environment exceeds standard industrial limits.

Current Sense Transformers Part Context

This part belongs to the Bourns PCS series of current sense transformers, which are engineered for precise current measurement in power conversion systems. The series utilizes planar or EE-style cores to minimize profile while maintaining magnetic efficiency. These components serve as critical isolation elements between high-voltage primary sides and low-voltage control circuitry.

Current Sense Transformers Replacement Considerations

Direct substitutes may include other Bourns models within the PCS series with matching EE5 footprints and similar inductance values, such as those offering 20 A ratings. Verify that alternative parts maintain the 1:30 turns ratio and 1 MHz frequency response to ensure circuit functionality remains unchanged.
