PTKM150R-894VM

Fixed Inductors Overview

The Delevan PTKM150R-894VM is a vertical mount toroidal power choke with an inductance of 150 uH and a tolerance of +/- 10%. It features radial leads for PCB mounting and supports a maximum DC current of 6.5 A. The component has a maximum DC resistance of 35 mOhms and a self-resonant frequency of 1 MHz. Physical dimensions include a width of 20.95 mm, length of 36.83 mm, and height of 37.46 mm.

Fixed Inductors Feature Summary

• Vertical mount toroidal core design for compact power filtering applications
• Radial leaded termination style suitable for standard PCB assembly
• High current handling capability up to 6.5 A with low DC resistance

Fixed Inductors Applications

• Power supply input/output filtering
• Common mode noise suppression in electronic circuits
• DC-DC converter output chokes

Fixed Inductors Procurement Notes

Verify the specific suffix '894' against the manufacturer's latest datasheet to confirm exact physical dimensions and pinout compatibility. Ensure the RoHS status matches project requirements, as some variants may differ. Confirm that the 6.5 A rating aligns with the thermal management capabilities of the target PCB layout.

Fixed Inductors Selection Notes

Select this component when a vertical form factor is required for space-constrained designs. Compare the 150 uH value and 6.5 A current rating against circuit simulation results to ensure adequate saturation margin. Consider the 1 MHz self-resonant frequency for high-frequency switching applications where parasitic effects must be minimized.

Fixed Inductors Part Context

This part belongs to the PTKMR series of toroidal power chokes from Delevan (API Delevan). The series offers various inductance values and current ratings in a vertical mount configuration. The 'VM' suffix typically denotes a specific packaging or variant within the broader product line, often associated with reel packaging for automated assembly.

Fixed Inductors Replacement Considerations

Direct substitutes include the PTKM150R-894 if the VM suffix does not indicate a functional change. Verify equivalent inductance, current rating, and physical footprint before substitution. Cross-reference with API Delevan's official replacement guide for validated alternatives.
