Procurement Notes
Verify the specific suffix 'S' against the manufacturer's official datasheet to confirm exact electrical tolerances and packaging specifications. Ensure the selected variant matches the required 900 mA current rating and 80V DC voltage limit for the target application environment. Cross-reference the part number with authorized distributors to confirm availability and authenticity.
Selection Notes
Select this component when a compact surface-mount solution is required for common mode noise reduction on data lines. The 40 µH inductance and 900 mA current rating suit moderate power applications. Verify that the 3.1 kΩ impedance meets the noise attenuation requirements at the operating frequency. Ensure the 9.2 x 6 x 5 mm package fits within the available PCB real estate constraints.
