Procurement Notes
Verify the complete part number including suffixes to ensure correct impedance and current ratings. Confirm RoHS compliance status if required by specific project regulations. Check moisture sensitivity level handling requirements during storage and assembly. Ensure packaging quantity matches production needs.
Selection Notes
Select this component when low DC resistance and moderate current handling are required for compact designs. The 0805 footprint suits space-constrained applications. Evaluate impedance characteristics against target frequency ranges to ensure effective noise attenuation without signal degradation.
Part Context
This device belongs to the WCM series of wire wound common mode filters from TAI-TECH. These components are designed for electromagnetic interference suppression in digital communication lines. The series offers various impedance values to match different signal frequencies and bandwidth requirements.
Replacement Considerations
Cross-reference with other 0805 two-line common mode chokes offering similar 160 Ohm impedance at 100 MHz. Verify current rating and DC resistance compatibility before substitution. Ensure package dimensions align with existing board layout constraints.
