1008CS-561EJTS

Overview

The 1008CS-561EJTS is a fixed wirewound inductor from Delta Electronics/Components, housed in a 1008 (2520 Metric) surface-mount package. It features an unshielded drum core design with a ceramic core material. The component provides an inductance of 560 nH with a tolerance of ±5%. It supports a rated current of 580 mA and exhibits a DC resistance of 1.33 Ohms. The self-resonant frequency is specified at 415 MHz, with a Q factor of 45 measured at 100 MHz. It operates within a temperature range of -40°C to 125°C.

Feature Summary

• Unshielded drum core construction for minimal magnetic interference
• Ceramic core material supporting high-frequency stability
• Surface-mount compatibility with standard 1008 footprint

Applications

• RF signal filtering circuits
• High-frequency power supply output stages
• Impedance matching networks in communication devices

Procurement Notes

Verify the specific suffix JTS against official Delta Electronics documentation to confirm tolerance and packaging specifications. Ensure that the 1008 package dimensions align with your PCB land pattern requirements. Cross-reference the 580 mA current rating with your circuit's maximum load conditions to prevent saturation. Confirm RoHS3 compliance status if required by your manufacturing standards.

Selection Notes

Select this component when a 560 nH inductance value is required in a compact 1008 SMD form factor. The unshielded design is suitable for applications where magnetic shielding is not critical or where external shielding is provided. Verify that the 1.33 Ohm DC resistance meets the efficiency requirements of your power path. Consider the 415 MHz self-resonant frequency to ensure operation remains below the resonant point for inductive behavior.

Part Context

This part belongs to the 1008CS series of wire-wound chip inductors manufactured by Delta Electronics. The series utilizes a ceramic open-type core structure designed for general-purpose high-frequency applications. The 1008 case size offers a balance between current handling capability and small footprint, distinguishing it from smaller 0603 or larger 1210 variants in the manufacturer's portfolio.

Replacement Considerations

The 1008CS-561EKTS is a documented variant within the same series. Verify if the KTS suffix indicates any differences in tolerance or packaging compared to the ETS version before substitution.
