Procurement Notes

Verify the specific impedance value and dimensional tolerances against the official Wurth Elektronik datasheet before finalizing procurement. Ensure the selected ferrite material composition aligns with the target frequency range requirements for the intended application to guarantee optimal signal integrity and noise reduction performance.

Selection Notes

Select this component when a toroidal form factor is required for cable wrapping applications. Consider the 99 Ω impedance at 25 MHz as the primary metric for determining suitability for the specific noise spectrum. Evaluate the 16 mm inner diameter to ensure compatibility with the cable bundle size being treated.

Part Context

This component belongs to the WE-TOF family of toroidal ferrite cores manufactured by Wurth Elektronik. These cores are engineered specifically for broadband EMI suppression tasks. The design prioritizes high permeability materials to maximize attenuation efficiency across a wide frequency band without introducing significant insertion loss to the desired signals.

Replacement Considerations

Consult the manufacturer's cross-reference documentation for verified substitute part numbers. Ensure any alternative maintains identical outer diameter, inner diameter, and height specifications to fit existing mechanical constraints.
