Arrays, Signal Transformers Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Bourns or authorized distributors before integration. Confirm that the dual-winding pinout matches the target schematic, as variations may exist between manufacturing lots. Ensure thermal management strategies account for the specified DC resistance losses at maximum operating currents.

Arrays, Signal Transformers Selection Notes

Select this component when a compact, shielded dual-inductor solution is required for space-constrained automotive designs. The SRF0703A series offers a balance of high current handling and low profile. Compare against single-winding alternatives if coupling is not required, or consider higher inductance values within the same package if circuit ripple constraints demand it.

Arrays, Signal Transformers Part Context

This part belongs to the SRF0703A series of dual-winding shielded power inductors manufactured by Bourns Electronic Solutions. The series is engineered specifically for demanding automotive environments, offering robust performance under varying thermal conditions. It complements other Bourns passive components used in vehicle electronics and industrial control systems.

Arrays, Signal Transformers Replacement Considerations

Direct substitutes must match the 8.2 µH value, dual-winding topology, and 0703 footprint. Verify equivalent AEC-Q200 certification and similar saturation characteristics. Cross-reference with Bourns SDR0703 variants only if single-winding functionality is acceptable.
