Procurement Notes

Verify the specific datasheet version for the 7110-RC to confirm RoHS compliance status and lead-free certification details. Ensure that the required operating temperature range aligns with your system's environmental conditions. Cross-reference the physical footprint dimensions (15.24 mm x 11.43 mm) with your PCB layout to guarantee proper clearance and mounting compatibility before finalizing procurement orders.

Selection Notes

Select this component when high current handling up to 3A is required alongside significant low-frequency noise attenuation. The low DC resistance minimizes power loss in the signal path. Consider the through-hole package type if automated surface-mount assembly is not available or if mechanical stability against vibration is a priority. Verify that the 510 µH inductance meets the specific cutoff frequency requirements of your EMI filter design.

Part Context

This component belongs to Bourns' common mode choke series, which are engineered for electromagnetic interference suppression. These chokes are typically utilized in scenarios requiring the mitigation of common mode noise on differential pairs or power lines. The product line emphasizes reliability and consistent performance across various industrial and consumer electronics applications, supporting both standard and specialized filtering needs.

Replacement Considerations

Consult official Bourns documentation for direct cross-references. Ensure any substitute part matches the 510 µH inductance, 3A current rating, and 20 mOhm DCR specifications. Verify that the replacement maintains the same through-hole package dimensions and operating temperature range to ensure mechanical and thermal compatibility without redesigning the circuit board.
