M-543CT

Common Mode Chokes Overview

The KEMET M-543CT is a surface mount common mode choke designed for signal line filtering. It features four lines with an impedance of 700 Ohms at 10 MHz and a maximum DC current rating of 1A. The component has a maximum DC resistance (DCR) of 100mOhm and a voltage rating of 50V DC. It operates within a temperature range of -25°C to 85°C. Physical dimensions are 8.90mm in length, 10.00mm in width, and a maximum height of 5.00mm.

Common Mode Chokes Feature Summary

• Four-line configuration for multi-signal interference suppression
• Low DC resistance for minimal signal loss
• Surface mount construction for automated assembly

Common Mode Chokes Applications

• Signal line filtering
• Common mode noise suppression in electronic circuits

Common Mode Chokes Procurement Notes

Verify the specific package variant required, as the part number corresponds to Tape & Reel, Cut Tape, and Digi-Reel options. Confirm that the 1A current rating and 700 Ohm impedance meet the design requirements. Ensure the operating temperature range of -25°C to 85°C is sufficient for the intended environment. Check RoHS3 compliance status if restricted substances are a concern.

Common Mode Chokes Selection Notes

Select this component when multi-line common mode noise reduction is required on signal paths. The low DCR ensures efficient power transmission or signal integrity with minimal voltage drop. The surface mount package facilitates compact PCB layouts. Verify that the 50V DC rating exceeds the maximum circuit voltage.

Common Mode Chokes Part Context

This component belongs to the M-500CT series of common mode chokes manufactured by KEMET. It is distinct from the T543 series polymer tantalum capacitors also listed in the provided data, which serve different functions in power supply decoupling and filtering applications.
