Common Mode Chokes Procurement Notes

Verify the specific suffix (e.g., -RC) against official Bourns documentation to confirm packaging type and RoHS compliance status. Ensure the selected variant matches the required inductance tolerance and current rating for the target application. Cross-reference the manufacturer part number with authorized distributors to obtain accurate availability and lead times. Confirm that the package style aligns with the intended PCB assembly process.

Common Mode Chokes Selection Notes

Select this component based on the required 2 mH inductance and 3.5 A current handling capability. Consider the 30 mOhm maximum DC resistance for efficiency requirements. Verify that the 17.78 x 17.78 mm footprint fits the design constraints. Ensure the operating temperature range of -55°C to +125°C meets environmental specifications. Check if the SMD package style is compatible with the manufacturing equipment.

Common Mode Chokes Part Context

This component belongs to the PM3700 series of common mode chokes from Bourns Electronic Solutions. The series is characterized by its compact surface-mount design suitable for space-constrained applications. These filters are engineered to suppress electromagnetic interference in both power and data lines. The PM3700-50-RC specifically denotes a variant with defined electrical parameters and packaging options.

Common Mode Chokes Replacement Considerations

Consult official Bourns substitution guides for verified alternatives. Ensure any substitute matches the 2 mH inductance, 3.5 A current rating, and 30 mOhm DCR. Verify compatibility with the 17.78 mm square footprint and 11.43 mm height. Confirm that the replacement part maintains the same operating temperature range and RoHS compliance status.
