AFBC-SG0402-700T

Overview

The AFBC-SG0402-700T is a surface-mount ferrite bead from the Abracon AFBC-SG0402 series, designed for high-frequency noise suppression in compact electronic circuits. It features a 0402 (1005 metric) package with dimensions of 1 mm length. The component provides an impedance of 70 Ohms at 100 MHz with a tolerance of ±25%. It supports a maximum DC current rating of 900 mA and has a maximum DC resistance of 200 mOhms. The device operates within a temperature range of -40°C to +85°C.

Feature Summary

• Provides effective attenuation of high-frequency electromagnetic interference signals through ferrite material properties
• Utilizes a compact 0402 surface-mount footprint suitable for space-constrained printed circuit board layouts
• Supports continuous direct current flow up to 900 mA without saturation

Applications

• High-speed digital signal line filtering
• Power supply output noise suppression
• Clock signal integrity enhancement

Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging configuration when ordering. Confirm RoHS compliance status matches project requirements. Ensure the selected distributor sources directly from authorized channels to guarantee component authenticity and traceability. Cross-reference the impedance value at 100 MHz against schematic specifications prior to procurement.

Selection Notes

Select this component when circuit design requires a low-profile ferrite bead capable of handling moderate DC currents while attenuating frequencies around 100 MHz. The 0402 package size is appropriate for dense PCB layouts where larger ferrite beads cannot fit. Consider the 200 mOhm DC resistance impact on power efficiency if used in sensitive low-voltage rails.

Part Context

This part belongs to the Abracon AFBC-SG0402 series of single-line ferrite beads. The series offers various impedance values tailored for different frequency suppression needs. The SG variant typically denotes standard performance characteristics within the 0402 form factor, balancing current handling capabilities with noise reduction effectiveness for general-purpose electronics.

Replacement Considerations

Compatible substitutes include other 0402 ferrite beads with similar 70 Ohm impedance at 100 MHz and comparable current ratings, such as the AFBC-SF0402-101T if higher current capacity is acceptable despite impedance differences.
