1008CS-680EKTS

Overview

The 1008CS-680EKTS is a fixed surface-mount inductor from Delta Electronics, featuring an unshielded drum core wirewound construction. It offers an inductance of 68 nH with a ±10% tolerance and a rated current of 1 A. The component exhibits a DC resistance of 200 mOhm and a Q value of 50 at 500 MHz. Its self-resonant frequency reaches 3.3 GHz, tested at 50 MHz. Designed for operation between -40°C and 125°C, it utilizes a ceramic magnetic core within a 1008 (2520 metric) package measuring 2.92mm x 2.79mm x 2.03mm.

Feature Summary

• Unshielded drum core wirewound design for high-frequency RF applications
• Ceramic magnetic core material ensuring stable performance across wide temperature ranges
• High self-resonant frequency capability suitable for signal filtering

Applications

• RF circuit impedance matching networks
• High-frequency signal filtering components
• Power supply input/output chokes

Procurement Notes

Verify the specific suffix EKTS against official Delta documentation to confirm the exact electrical parameters, particularly the 200 mOhm DCR and 1 A rating. Ensure the 1008 package dimensions align with PCB footprint requirements. Confirm RoHS3 compliance status through the manufacturer's latest datasheet before finalizing procurement specifications.

Selection Notes

Select this component when an unshielded inductor is required to minimize magnetic interference coupling in adjacent circuits. The 1008 package size provides a balance between current handling capacity and board space efficiency. Consider the 3.3 GHz self-resonant frequency limit to ensure effective operation within the intended RF bandwidth without parasitic resonance issues.

Part Context

This part belongs to the 1008CS series of ceramic RF inductors manufactured by Delta Electronics/Components. The series encompasses various inductance values ranging from 4.7 nH to 15,000 nH, all sharing the standardized 1008 physical footprint. This specific model represents a mid-range inductance option optimized for general-purpose RF filtering tasks.

Replacement Considerations

Direct substitutes include other 1008CS series variants such as 1008CS-680EGTS, which shares identical physical dimensions but may differ in DC resistance or current ratings. Verify that any replacement maintains the same 68 nH inductance and compatible Q factor for circuit continuity.
