ACM-21H-121-T

Overview

The ACM-21H-121-T is a two-line common mode choke manufactured by Abracon LLC, designed for surface mount applications. It features an impedance of 120 Ohms at 100 MHz and supports a maximum DC current rating of 280 mA. The component has a maximum DC resistance (DCR) of 400 milliohms and operates within a temperature range of -40°C to +105°C. Its physical dimensions are 2.00 mm in length, 1.20 mm in width, and 1.397 mm in height.

Feature Summary

Provides signal line filtering through common mode noise suppression
Utilizes wirewound construction with ferrite core material
Designed for compact surface mount PCB integration

Applications

Signal line noise suppression
Common mode interference reduction in electronic circuits

Procurement Notes

Verify the specific part number ACM-21H-121-T against official Abracon documentation to confirm electrical parameters and mechanical dimensions. Ensure compatibility with RoHS3 compliance requirements and check moisture sensitivity level classifications before procurement. Cross-reference datasheet revisions to validate performance specifications.

Selection Notes

Select this component based on its 120 Ohm impedance at 100 MHz and 280 mA current rating. Consider the 400 milliohm DCR for power loss calculations. Verify that the 1.397 mm height fits within the assembly clearance constraints. Confirm the operating temperature range meets the environmental requirements of the target application.

Part Context

This component belongs to the ACM-21 series of chip wire wound common mode chokes from Abracon Corporation. The series offers various impedance and current ratings tailored for different signal integrity needs. The ACM-21H variant specifically denotes the high-temperature capability up to 105°C, distinguishing it from standard temperature range counterparts.
