Procurement Notes
Verify the manufacturer part number against official TDK Electronics documentation to confirm specifications. Ensure the procurement source provides valid RoHS compliance certificates. Cross-reference the lead time and authenticity with authorized distributors. Confirm that the received components match the physical dimensions and terminal configuration described in the datasheet.
Selection Notes
Select this component when designing circuits requiring common mode noise attenuation for low-current signal lines. Consider the 700 mA current rating and 1.1 Ohm DC resistance for voltage drop calculations. Evaluate the thermal performance within the -40°C to 125°C operating range. Ensure the through-hole footprint fits the target PCB layout constraints.
Part Context
This component belongs to the EPCOS B82732 series of common mode chokes. The series offers various inductance values and current ratings for different filtering requirements. EPCOS, now part of TDK Electronics, specializes in passive electronic components for automotive, industrial, and consumer electronics markets.
Replacement Considerations
Consult official TDK Electronics substitution guides for verified alternative part numbers. Do not assume cross-compatibility based on similar electrical parameters alone. Verify mechanical fit and pinout compatibility before replacing.
