1008CS-271EKTS

Overview

The 1008CS-271EKTS is an unshielded drum core, wirewound inductor from the Delta Electronics/Components 1008CS series. It features a ceramic core and operates within a temperature range of -40°C to 125°C. The component has an inductance of 270 nH with a tolerance of ±10%. It supports a rated current of 690 mA and exhibits a DC resistance of 910 mOhm. The self-resonant frequency is specified at 600 MHz, with a Q value of 50 measured at 250 MHz. The device utilizes a surface mount installation type in a 1008 (2520 Metric) package.

Feature Summary

• Unshielded drum core construction utilizing wirewound technology for RF applications
• Ceramic core material providing stable performance across wide temperature ranges
• Surface mount design compatible with automated assembly processes

Applications

• RF circuit filtering
• Signal processing networks
• General purpose inductive components in electronic assemblies

Procurement Notes

Verify the specific ordering suffix to ensure correct tolerance and packaging configuration. Confirm that the 1008 (2520 Metric) footprint matches the target PCB layout dimensions. Check for RoHS3 compliance status if environmental regulations apply to the final product. Ensure the rated current and DC resistance parameters meet the circuit requirements before integration.

Selection Notes

Select this component when an unshielded inductor is required to minimize magnetic interference with nearby sensitive circuits. The 1008 package size offers a balance between current handling capability and board space efficiency. Consider the 690 mA rated current and 910 mOhm DCR for power loss calculations. The ceramic core provides thermal stability suitable for demanding operating environments.

Part Context

This part belongs to the 1008CS series of fixed inductors manufactured by Delta Electronics/Components. The series includes various inductance values tailored for different RF and general electronic applications. The 1008CS designation indicates the specific case size and series characteristics, distinguishing it from other Delta inductor lines such as the 0805CS series.

Replacement Considerations

AISC-0805-R27G-T is listed as a similar alternative by Abracon LLC. Verify package compatibility as the substitute uses an 0805 footprint, which differs from the 1008 size of the original part. Electrical parameter matching is essential when considering cross-package replacements.
