EMI1206R-90

Chip Ferrite Bead Overview

The Delevan EMI1206R-90 is a surface-mount ferrite chip bead designed for EMI and RFI suppression. It features a 1206 (3216 metric) package with dimensions of 3.2 mm length, 1.6 mm width, and 1.1 mm height. The component provides an impedance of 90 Ohms at a test frequency of 100 MHz with a tolerance of 25%. It supports a maximum DC current of 500 mA and has a maximum DC resistance of 150 mOhms. The operating temperature range spans from -55°C to +125°C.

Chip Ferrite Bead Feature Summary

Chip Ferrite Bead Procurement Notes

Verify the specific manufacturer designation, as API Delevan components may be sourced under various corporate identifiers. Confirm RoHS compliance status through official documentation prior to integration. Ensure the ordering quantity aligns with standard reel packaging requirements specified by the supplier. Cross-reference the part number against current distributor catalogs to confirm availability and authenticity before finalizing procurement plans.

Chip Ferrite Bead Selection Notes

Select this component when a low-impedance path is required for DC signals while attenuating noise around 100 MHz. The 500 mA current rating suits moderate power applications. The 1206 footprint allows for space-constrained designs. Verify that the 150 mOhms DC resistance meets the voltage drop constraints of the target circuit. Ensure the operating environment stays within the specified -55°C to +125°C thermal limits.

Chip Ferrite Bead Part Context

This ferrite bead belongs to the EMI1206R series, which offers various impedance values in a standardized 1206 package. The series is engineered for broad-spectrum noise reduction in consumer and industrial electronics. Delevan manufactures these components to provide reliable signal integrity protection without significantly impacting the primary signal path.
