Overview
The ACM-31-102M-T is a two-line common mode choke manufactured by Abracon LLC, designed for surface mount applications. It features an impedance of 1 kOhms at 100 MHz and supports a maximum DC current of 230 mA. The component has a maximum DC resistance (DCR) of 1 Ohm and operates within a temperature range of -40°C to 85°C. Its physical dimensions are 3.00 mm in length, 1.60 mm in width, and a maximum height of 2.00 mm. The device utilizes a horizontal package with four PCB pads.
Feature Summary
- Provides common mode noise suppression for signal lines through dual-line filtering capabilities.
- Utilizes a compact surface mount footprint suitable for space-constrained printed circuit board layouts.
- Constructed with wire-wound technology to achieve specified impedance characteristics at high frequencies.
Applications
- Signal line filtering in electronic circuits
- Common mode noise reduction in data transmission interfaces
- EMI suppression in portable electronic devices
Procurement Notes
Verify the specific ordering suffix to ensure the correct packaging format, such as tape and reel or cut tape, matches production requirements. Confirm that the RoHS3 compliance status aligns with environmental regulations applicable to the target market. Ensure the moisture sensitivity level classification is considered during storage and handling procedures to maintain component integrity before assembly.
Selection Notes
Select this component when a low-profile, two-line common mode choke is required for high-frequency noise attenuation. The 1 kOhm impedance at 100 MHz makes it suitable for suppressing electromagnetic interference in sensitive signal paths. Consider the 230 mA current rating to ensure adequate performance without saturation under expected operating conditions.
Part Context
This part belongs to the ACM-31 series of chip wire-wound common mode chokes from Abracon. The series offers various impedance and current ratings in a standardized small outline package. These components are engineered for general-purpose EMI filtering in consumer electronics and industrial equipment where space efficiency is critical.
Replacement Considerations
Consult official manufacturer substitution guides for verified equivalents. Cross-referencing requires matching impedance values, current ratings, and physical dimensions to ensure functional compatibility without redesigning the footprint.
