HF55BTL3.5X8R-AG

Chip Ferrite Bead Overview

The TDK HF55BTL3.5X8R-AG is an axial leaded ferrite bead designed for electromagnetic interference (EMI) suppression in electronic circuits. It exhibits a nominal impedance of 125 Ohms at a frequency of 100 MHz. The component utilizes a cylindrical core with axial leads, measuring 3.50 mm in diameter and 8.00 mm in length. This configuration supports through-hole mounting on printed circuit boards.

Chip Ferrite Bead Feature Summary

• Provides effective high-frequency noise attenuation for signal integrity preservation
• Axial leaded construction facilitates straightforward through-hole PCB integration
• Optimized material composition ensures targeted EMI suppression characteristics

Chip Ferrite Bead Applications

• High-frequency circuit noise suppression
• Electromagnetic interference filtering in electronic assemblies
• Signal line protection against high-frequency disturbances

Chip Ferrite Bead Procurement Notes

Verify the specific impedance value of 125 Ohms at 100 MHz against design requirements. Confirm the axial package dimensions of 3.50 mm diameter by 8.00 mm length fit the mechanical constraints. Ensure the manufacturer is confirmed as TDK Corporation to guarantee component authenticity and performance consistency.

Chip Ferrite Bead Selection Notes

Select this component when axial mounting is required for EMI suppression applications. The 125 Ohm impedance at 100 MHz defines its filtering capability. Consider the physical size constraints due to the 8.00 mm length. Verify compatibility with through-hole assembly processes and soldering temperatures suitable for ferrite materials.

Chip Ferrite Bead Part Context

This ferrite bead belongs to TDK's series of passive components focused on noise suppression. It serves as a critical element for maintaining signal integrity in high-speed digital and analog circuits. The axial form factor distinguishes it from surface-mount alternatives, offering robust mechanical attachment for specific industrial or consumer electronics designs.

Chip Ferrite Bead Replacement Considerations

The HF55BTL3.5X4.5R-AG is a documented alternative within the same product family. It shares the axial package style but differs in impedance specifications. Evaluate the 74 Ohm impedance characteristic against the original 125 Ohm requirement before substitution.
