Procurement Notes
Verify the exact part number suffix against official Eaton documentation to ensure correct packaging and tape-and-reel configuration. Confirm that the specified inductance tolerance and current ratings align with the target circuit requirements before finalizing procurement orders.
Selection Notes
Select this component when a compact surface-mount pulse transformer is required for SMPS designs. Ensure the 173 µH inductance and 0.14 A current limit meet the system's electrical constraints. Evaluate the physical footprint compatibility with the printed circuit board layout during the design phase.
Part Context
This component belongs to the VP Versa-Pac series of inductors and transformers from Eaton Electronics Division. The series provides various magnetic components designed for efficient energy storage and signal processing in modern electronic systems, emphasizing reliability and space-saving form factors.
Replacement Considerations
Cross-reference with other Eaton VP series variants or equivalent surface-mount pulse transformers from different manufacturers if supply constraints exist. Verify pinout compatibility and electrical parameter equivalence before substitution.
