Procurement Notes

Verify the specific datasheet version for the PH9400.111NLT to confirm electrical parameters such as inductance and isolation ratings before finalizing design integration. Ensure that the surface mount footprint matches the PCB layout requirements. Confirm compliance with environmental regulations relevant to the target market, such as RoHS3 status, by checking the manufacturer's official documentation.

Selection Notes

Select this component when a 1:1:1 turns ratio and 4.5 mH inductance are required for gate drive isolation. Consider the 4000 Vrms isolation rating for safety requirements. Evaluate the operating temperature range of -40 °C to +125 °C against environmental conditions. Compare physical dimensions of 16.70 mm x 12.70 mm x 14.20 mm with available board space constraints.

Part Context

This part belongs to the PH9400 series of transformers manufactured by Pulse Electronics. The series includes various models with different inductance values and isolation voltages, such as the PH9400.111ANLT which offers 1.21 mH inductance and 2 kV isolation. The PH9400 series is generally utilized in applications requiring reliable galvanic isolation for control signals.

Replacement Considerations

The PH9400.111ANLT is a related model within the same series but differs in inductance (1.21 mH vs 4.5 mH) and isolation voltage (2 kV vs 4 kV). Verify if these parameter differences meet the specific circuit requirements before substituting.
