Procurement Notes
Verify the complete part number including suffixes against official manufacturer documentation to ensure correct impedance and tolerance specifications. Confirm RoHS compliance status and lead-free certification requirements prior to ordering. Ensure storage conditions align with manufacturer guidelines to maintain component integrity during handling and assembly processes.
Selection Notes
Select this component when designing circuits requiring common mode noise attenuation at 100 MHz with limited space constraints. Evaluate the 400mA current rating against peak operational loads to prevent saturation. Consider the 250 milliohm DC resistance impact on signal integrity and power loss within the specific application environment.
Part Context
This component belongs to the category of passive electromagnetic interference filters produced by Walsin Technology Corporation. It utilizes thin-film or similar SMD construction techniques suitable for automated placement. The product line focuses on providing reliable noise suppression solutions for modern electronics manufacturing.
Replacement Considerations
Consult official Walsin cross-reference lists for verified substitutes. Ensure replacement parts match the 2512 package dimensions, 67 ohm impedance at 100 MHz, and 400mA current rating. Verify that alternative components meet the same thermal and electrical performance standards.
