Common Mode Chokes Procurement Notes

Verify the specific part number suffix against official TDK documentation to ensure correct inductance and current ratings. Confirm that the vertical mounting orientation matches the PCB layout requirements. Check certification marks such as UL and CSA on the physical component or datasheet to validate safety compliance for the target market. Ensure the operating temperature range meets the environmental conditions of the final assembly.

Common Mode Chokes Selection Notes

Select this component when high inductance is required for power line noise reduction in single-phase applications. The 2.8A rating suits moderate power loads, while the 4.7mH value provides significant common mode attenuation. Consider the vertical form factor for space-constrained boards where height is less critical than footprint. Verify thermal management capabilities given the 120°C maximum operating temperature limit.

Common Mode Chokes Part Context

This part belongs to the TDK HF series of common mode choke coils, which are engineered for power line filtering. The series utilizes closed magnetic circuit cores to maximize inductance efficiency. The HF2836 variant specifically denotes a larger package size compared to smaller surface-mount or low-profile through-hole options, supporting higher current and inductance values for demanding power supply environments.

Common Mode Chokes Replacement Considerations

Direct substitutes must match the 4.7mH inductance, 2.8A current rating, and vertical through-hole package dimensions. Verify equivalent safety certifications (UL, CSA, IEC) and similar DC resistance characteristics. Cross-reference with other TDK HF series models like HF2826 if dimensional constraints differ, ensuring electrical parameters remain compatible.
