Chip Ferrite Bead Procurement Notes

Verify the specific manufacturer designation API Delevan or Delevan when sourcing, as corporate structures may vary. Confirm the impedance value of 120 Ohms at 100 MHz matches your circuit requirements. Ensure the 1206 package footprint aligns with your PCB layout. Check RoHS compliance status through official documentation before integration into regulated products.

Chip Ferrite Bead Selection Notes

Select this component when a 120 Ohm impedance at 100 MHz is required for noise reduction. The 500 mA current rating suits moderate power applications. The wide operating temperature range supports harsh environments. Consider the unshielded nature if magnetic coupling with nearby components is a concern. Verify the 150 mOhm DC resistance fits your voltage drop constraints.
