Arrays, Signal Transformers Procurement Notes

Verify the specific suffix 'M' confirms the standard tape-and-reel packaging format required for automated assembly processes. Confirm that the thermal characteristics align with the target application's operating environment limits. Ensure the footprint dimensions match the PCB layout specifications before finalizing procurement orders.

Arrays, Signal Transformers Selection Notes

Select this component when dual independent windings or coupled inductor functionality is required in a compact form factor. Consider the 0.89 A saturation current limit against peak load requirements. Evaluate the 324.7 µH series configuration if higher impedance is needed compared to the individual 82 µH winding value.

Arrays, Signal Transformers Part Context

This part belongs to the SRF0703A series of dual-winding shielded power inductors from Bourns. The series provides various inductance values ranging from 8.2 µH to 600 µH, designed for high-current applications. The SRF0703A-820M specifically offers 82 µH inductance, fitting into the mid-range of the series for balanced performance between size and electrical characteristics.

Arrays, Signal Transformers Replacement Considerations

Check for direct cross-reference parts within the same series, such as SRF0703A-101M, which shares similar physical dimensions but differs in inductance value. Verify pinout compatibility and magnetic shielding requirements when substituting with components from other manufacturers.
