0805CS-272EJFS

Fixed Inductors Overview

The Delta Electronics/Components 0805CS-272EJFS is a fixed surface-mount inductor from the 0805CS series. It features an unshielded drum core wirewound design with a ferrite core material. The component provides an inductance of 2.7 µH with a tolerance of ±5%. It has a DC resistance (DCR) of 1.2 Ohms and a rated current of 320 mA. The self-resonant frequency is 50 MHz, measured at a test frequency of 7.96 MHz. The Q factor is 16 at 7.9 MHz. It operates within a temperature range of -40°C to 85°C and is packaged in tape and reel format.

Fixed Inductors Feature Summary

• Unshielded drum core wirewound construction for general-purpose applications
• Ferrite core material supporting stable inductance characteristics
• Surface mount installation in standard 0805 package dimensions

Fixed Inductors Applications

• General purpose signal processing circuits
• RF filtering applications requiring unshielded components
• Power supply input/output filtering

Fixed Inductors Procurement Notes

Verify the specific operating temperature rating against application requirements, as datasheet sources indicate a maximum of 85°C for this suffix variant. Confirm availability status directly with the manufacturer or authorized distributors, as inventory levels fluctuate. Ensure the tape and reel packaging aligns with automated assembly equipment specifications prior to ordering.

Fixed Inductors Selection Notes

Select this component when a 2.7 µH inductance value is required in a compact 0805 footprint. The 320 mA current rating suits low-to-medium power signal paths. Consider the unshielded nature for layout planning to manage magnetic field interference. Verify that the 1.2 Ohm DCR meets voltage drop constraints in the target circuit design.

Fixed Inductors Part Context

This part belongs to the Delta Electronics 0805CS series of fixed inductors. The series offers various inductance values in the 0805 surface-mount package. The 0805CS-272EJFS specifically denotes the 2.7 µH variant with ferrite core construction. It is distinct from ceramic core variants like the 0805CT series which operate at higher frequencies.

Fixed Inductors Replacement Considerations

The 0805CS-272EJTS is a similar variant within the same series but may differ in temperature rating or manufacturing batch specifications. Cross-reference electrical parameters such as DCR and current rating before substitution.
