Arrays, Signal Transformers Procurement Notes

Verify the specific suffix 'K' corresponds to the required tolerance and packaging configuration for your production line. Confirm that the lead frame material and plating finish meet your assembly process requirements. Ensure the storage conditions remain within specified humidity and temperature limits prior to soldering to maintain solderability integrity.

Arrays, Signal Transformers Selection Notes

Select this component when designing multiphase converters requiring high current density and tight ripple control. Evaluate the 61A saturation limit against peak load transients to prevent magnetic saturation. Consider the 27A RMS rating relative to continuous thermal dissipation constraints on the target PCB layout.

Arrays, Signal Transformers Part Context

This part belongs to the ERUC23 series of coupled inductors manufactured by EPCOS, now integrated into TDK Electronics. The series is specifically engineered for advanced power management solutions where size reduction and efficiency are critical. It represents a shift towards integrated magnetic components that replace discrete inductors in complex power stages.

Arrays, Signal Transformers Replacement Considerations

Direct substitutes include other ERUC23 variants such as ERUC23-1R4K, ERUC23-1R8K, ERUC23-2R2K, ERUC23-3R2K, and ERUC23-4R1K, which share identical mechanical dimensions and pinout configurations but offer different inductance values. Verify electrical parameters match the circuit design before substitution.
