Procurement Notes
Verify the specific suffix against manufacturer documentation to confirm exact reel quantities and tape specifications. Ensure that the ordering code matches the required inductance value and tolerance limits defined in the official datasheet. Confirm RoHS compliance status directly from the latest product release notes prior to finalizing procurement orders.
Selection Notes
Select this component when designing circuits requiring common mode rejection for differential signaling applications. Evaluate the saturation current requirements against the specified 2 A limit to prevent performance degradation. Consider the low profile dimensions for space-constrained board designs where standard through-hole components cannot fit.
