Overview
The CM2824E702R-10 is a surface-mount common mode choke from the Laird CM series, designed for signal line applications. It features two lines with an inductance of unspecified value at 100 kHz and an impedance of 800 Ohms at 100 MHz. The component supports a maximum DC current of 700 mA and has a maximum DC resistance of 260 mOhm. Rated voltages are 80V DC and 42V AC. Operating temperature ranges from -40°C to +125°C. Physical dimensions are 9.00 mm length, 5.50 mm width, and 4.90 mm height.
Feature Summary
- Provides common mode noise suppression for signal lines
- Surface mount construction for automated PCB assembly
- Dual-line configuration for differential signaling protection
Applications
- Signal line filtering in electronic circuits
- Noise suppression in high-speed data interfaces
- EMI reduction in compact consumer electronics
Procurement Notes
Verify the specific impedance frequency rating against application requirements, as datasheets may list 800 Ohms at 100 MHz. Confirm the inductance value specification, as some sources omit this parameter. Ensure the 700 mA current rating meets circuit demands. Check RoHS3 compliance status if required by project specifications. Validate package dimensions against PCB footprint constraints.
Selection Notes
Select this component for applications requiring dual-line signal integrity maintenance in space-constrained designs. The 4.90 mm height accommodates low-profile board assemblies. Consider the 260 mOhm DCR impact on signal loss. Compare with similar Laird models if higher current or different impedance characteristics are needed. Ensure compatibility with standard SMT reflow processes.
Part Context
This part belongs to the Laird CM series of common mode chokes, manufactured by Laird-Signal Integrity Products. The series offers various inductance and current ratings for signal line protection. The CM2824E702R-10 specifically targets mid-range noise suppression needs with a balance of current handling and impedance performance in a compact SMD package.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout and dimensional compatibility before considering alternative manufacturers' components.
