1008CS-270EKTS

Overview

The 1008CS-270EKTS is a fixed surface-mount inductor from Delta Electronics/Components, featuring a ceramic drum core and wound construction. It provides an inductance of 27 nH with a tolerance of ±10%. The component supports a rated current of 1 A and exhibits a DC resistance of 130 mΩ. It operates within a temperature range of -40°C to 125°C and achieves a self-resonant frequency of 2.45 GHz. Packaged in a 1008 (2520 metric) footprint, it measures 2.92 mm in length, 2.79 mm in width, and has a maximum height of 2.03 mm.

Feature Summary

• Utilizes a ceramic drum core for stable performance in RF applications
• Offers high self-resonant frequency suitable for signal filtering
• Supports standard surface mount assembly processes

Applications

• RF circuit filtering
• Impedance matching networks
• Signal processing circuits

Procurement Notes

Verify the specific manufacturer designation, as sources indicate Cyntec or Delta Electronics/Components. Confirm the DC resistance value, as documentation varies between 90 mΩ and 130 mΩ for this part number. Ensure the package dimensions match the required 1008 footprint constraints for your PCB layout.

Selection Notes

Select this component when a low-inductance value near 27 nH is required for high-frequency operation. The 1 A current rating must be sufficient for the target circuit's load. Verify that the unshielded design does not cause electromagnetic interference issues in dense layouts.

Part Context

This component belongs to the 1008CS series of fixed inductors. The series utilizes ceramic drum cores and is designed for surface mount technology. Similar parts in the series include the 1008CS-120EKTS and 1008CS-270EJTS, which share the same physical footprint but differ in inductance and tolerance specifications.

Replacement Considerations

The 1008CS-270EJTS is a verified substitute offering identical electrical characteristics with a tighter ±5% tolerance instead of ±10%.
