Procurement Notes

Verify the specific suffix 'EJTS' against official Delta documentation to confirm tape width, terminal wraparound specifications, and reel quantity details. Ensure compatibility with RoHS3 and REACH regulations as stated in manufacturer data. Cross-reference the DigiKey part number 1008CS-221EJTS-ND for accurate ordering information and availability status before finalizing procurement plans.

Selection Notes

Select this component when a 220 nH inductance value is required in a compact 1008 footprint. Consider the 500 mA current rating and 840 mOhm DCR for power loss calculations. The high self-resonant frequency of 700 MHz makes it appropriate for higher frequency applications compared to lower-frequency alternatives. Verify that the unshielded design does not interfere with nearby sensitive circuitry.

Part Context

This part belongs to the 1008CS series of general-purpose fixed inductors manufactured by Delta Electronics/Components. The series offers various inductance values within the same physical envelope, allowing for design flexibility. The 1008CS line is characterized by its wirewound construction and ceramic core, providing a balance between size constraints and electrical performance for consumer and industrial electronics.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. When evaluating alternatives, ensure the replacement matches the 220 nH inductance, 1008 package dimensions, and similar current ratings. Verify that any substitute maintains comparable self-resonant frequency and Q factor requirements for the specific application.
