Arrays, Signal Transformers Procurement Notes

Verify the obsolete status of this specific part number before procurement planning. Confirm availability of active replacements such as the PM3602-20-RC variant, which offers identical electrical specifications but utilizes tape and reel packaging instead of bulk. Ensure that the selected substitute matches the required mounting style and supply chain requirements for production continuity.

Arrays, Signal Transformers Selection Notes

Select this component when unshielded magnetic coupling is acceptable for the application layout. Consider the PM3602-20-RC if automated assembly processes require reel packaging rather than bulk trays. Evaluate thermal management capabilities given the 125°C upper operating limit and ensure current ratings align with peak load conditions in both series and parallel modes.

Arrays, Signal Transformers Part Context

This component belongs to the Bourns PM3600 series of signal transformers and inductor arrays. The series provides compact solutions for multi-winding requirements on printed circuit boards. The PM3602 base model specifically denotes a two-coil configuration available in various inductance values and packaging options to suit diverse electronic design constraints.

Arrays, Signal Transformers Replacement Considerations

Public confirmed substitute: PM3602-20-RC. This alternative maintains identical electrical parameters including 20 µH inductance and current ratings. The primary difference lies in the packaging format, with the RC suffix indicating tape and reel delivery suitable for high-volume surface mount manufacturing.
