Procurement Notes

Verify the specific impedance requirements against the application frequency spectrum before procurement. Confirm that the inner diameter accommodates the target cable or bundle diameter within the specified operational range. Ensure compliance with environmental standards such as RoHS if required by the end-use environment. Cross-reference the material designation to confirm suitability for the intended noise profile.

Selection Notes

Select this component when a non-invasive solution for cable noise reduction is required. The hinged design is preferred over solid cores for retrofitting existing wiring harnesses. Consider the operating temperature range and the specific impedance curve of Material 44 relative to the noise frequencies present in the system. Ensure the physical dimensions fit within the available space constraints of the assembly.
