Overview
The Delta Electronics/Components 1008CS-220EJTS is a fixed surface-mount inductor designed for high-frequency applications. It features a ceramic core and wirewound construction within a 1008 (2520 metric) package. The component provides an inductance of 22 nH with a tolerance of ±5%. It supports a rated current of 1 A and exhibits a DC resistance of 120 mΩ. Key electrical characteristics include a Q value of 55 at 350 MHz, a self-resonant frequency of 2.4 GHz, and testing at 50 MHz. It operates between -40°C and 125°C.
Feature Summary
- Unshielded drum core wirewound design utilizing ceramic magnetic material
- High self-resonant frequency capability up to 2.4 GHz
- RoHS3 compliant and REACH unaffected environmental status
Applications
- RF circuit filtering and impedance matching
- DC-DC converter input/output chokes
- General purpose signal processing circuits
Procurement Notes
Verify the specific ordering suffix to ensure correct tolerance and packaging configuration. Confirm that the 1008 package dimensions align with the target PCB footprint. Check RoHS3 compliance requirements against project specifications. Ensure thermal management strategies account for the 1 A rated current limit during operation.
Selection Notes
Select this component when a low-inductance value near 22 nH is required for high-speed switching or RF paths. The 1008 case size offers a balance between current handling and board space compared to smaller packages. Consider the 120 mΩ DCR impact on efficiency if power loss is a critical constraint. Verify that the 1 A saturation current meets the peak load demands of the application.
Part Context
This part belongs to the 1008CS series of fixed inductors from Delta Electronics/Components. The series utilizes ceramic cores for stable performance across temperature variations. Similar parts in the series vary by inductance values and package sizes, such as the 0805CS variant. The 1008CS series is designed for surface mount assembly processes.
Replacement Considerations
Cross-reference with other manufacturers offering 22 nH inductors in the 1008 (2520 metric) package. Verify that substitute components match the 1 A current rating and 120 mΩ DCR limits. Ensure the replacement maintains the same self-resonant frequency characteristics for RF integrity.
