Overview
The ACM-31-261M-T is a two-line surface mount common mode choke manufactured by Abracon LLC. It features an impedance of 260 Ohms at 100 MHz and a rated current of 310 mA. The DC resistance (DCR) is 500 milliohms, with a maximum DC voltage rating of 50V. The component operates within a temperature range of -40°C to 85°C and utilizes a horizontal 4-pin package measuring 3.00mm x 1.60mm x 2.00mm.
Feature Summary
- Provides common mode noise suppression for signal lines in compact surface mount configurations
- Designed for high-frequency interference attenuation at 100 MHz
- Constructed as a chip wire wound component suitable for automated assembly
Applications
- Signal line filtering in electronic circuits
- Noise suppression in data transmission interfaces
- Common mode choke applications requiring low profile SMD packaging
Procurement Notes
Verify the specific manufacturer part number ACM-31-261M-T against official Abracon documentation to ensure accuracy. Confirm that the required electrical parameters, including the 310mA current rating and 260 Ohm impedance, align with the design specifications. Check for RoHS3 compliance status if environmental regulations apply to the final product assembly.
Selection Notes
Select this component when a two-line common mode choke with a 310mA current rating is required for space-constrained designs. The 500 milliohm DCR supports low power loss applications. Ensure the 50V DC voltage rating meets the circuit requirements. The horizontal 4-pin package facilitates standard surface mount placement processes.
Part Context
This component belongs to the ACM-31 series of chip wire wound common mode chokes from Abracon LLC. The series offers various impedance and current ratings tailored for different signal integrity needs. The ACM-31 designation indicates a specific form factor optimized for high-density PCB layouts while maintaining effective electromagnetic interference filtering capabilities.
Replacement Considerations
Consult official Abracon documentation for verified substitute part numbers within the ACM-31 series or equivalent components from other manufacturers. Ensure any replacement matches the 260 Ohm impedance at 100 MHz and 310mA current rating.
