Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm tolerance and packaging specifications. Ensure that the selected variant matches the required electrical parameters for the target application circuit. Cross-reference the part number with official distributor catalogs to confirm availability and lead times prior to finalizing procurement plans.

Selection Notes

Select this component when a 2.2 µH inductance value is required in a 1008 surface-mount package. Consider the 280 mA current rating and 2.8 ohm DC resistance to ensure compatibility with the circuit's power budget. Evaluate the 160 MHz self-resonant frequency to verify suitability for the intended operating frequency range.

Part Context

This part belongs to the 1008CS series of ceramic RF inductors manufactured by Delta Electronics/Components. The series provides various inductance values within the 1008 (2520 metric) package size, catering to applications requiring unshielded wirewound components with ceramic cores for high-frequency performance.

Replacement Considerations

The datasheet does not list confirmed substitute part numbers. Designers should evaluate other 1008CS series variants or comparable unshielded wirewound inductors from different manufacturers based on matching inductance, current rating, and physical dimensions.
