Procurement Notes
Verify the specific impedance value and current rating against the official Abracon datasheet before integration. Confirm that the package dimensions match the target footprint. Ensure the operating temperature range meets system requirements. Check RoHS compliance status if mandated by project specifications. Validate supplier authenticity through authorized distribution channels.
Selection Notes
Select this component when a low-profile, high-impedance common mode choke is required for 1A applications. Compare DCR values against power loss constraints. Evaluate physical size compatibility with existing board space. Consider the frequency response characteristics relative to the noise spectrum. Verify pin configuration matches the schematic design.
Part Context
This part belongs to the ACMP-7038 series of common mode chokes from Abracon. The series offers various impedance and current ratings tailored for different signal integrity needs. The ACMP-7038-272-T specifically targets applications requiring 2700 ohms impedance at 100 MHz. It shares the same mechanical footprint as other variants in the series, facilitating design flexibility.
Replacement Considerations
Direct substitutes include ACMP-7038-302-T for higher impedance or ACMP-7038-700-T for higher current capacity. Verify electrical parameters and physical dimensions before substitution. Consult manufacturer cross-reference guides for compatible alternatives.
