- Surface mount circuit assemblies requiring common mode chokes
Common Mode Chokes Procurement Notes
Verify the specific part number PM3700-40-RC against official Bourns documentation to confirm electrical parameters such as 1 mH inductance and 4A current rating. Ensure compatibility with surface mount processes and check for RoHS compliance status in the latest datasheet before procurement.
Common Mode Chokes Selection Notes
Select this component when a surface-mount common mode choke with a 4A current rating and 1 mH inductance is required. Consider the 21.60mm square footprint and 0.450-inch height for board space constraints. Verify that the unshielded design meets EMI requirements for the specific application environment.
Common Mode Chokes Part Context
This component belongs to the Bourns PM3700 series of SMD common mode chokes. The series offers various current ratings up to 7A and includes compact body sizes. The PM3700-40-RC specifically addresses applications needing moderate inductance and high current handling in a surface-mount package.
Common Mode Chokes Replacement Considerations
Consult official Bourns substitution guides or distributor cross-reference tools for verified equivalent parts. Do not assume functional interchangeability based on similar specifications alone without confirming pinout, thermal, and mechanical compatibility.
