### Overview of CMT1-6-R The **CMT1-6-R** is a high-performance, through-hole **Common Mode Choke** manufactured by Coiltronics (a brand of Eaton). It is primarily designed to suppress electromagnetic interference (EMI) and noise in power supply and filtering applications. --- ### Technical Specifications The following table summarizes the key electrical and physical characteristics of the CMT1-6-R: | Parameter | Specification | | :--- | :--- | | **Inductance (Typical)** | 6.4 mH | | **Current Rating (Max)** | 2.4 A | | **DC Resistance (DCR)** | 0.120 $\Omega$ (Max) | | **Turns Ratio** | 1:1 | | **Isolation Voltage** | 1500 Vac | | **Operating Temperature** | -40°C to +125°C | | **Mounting Type** | Through-hole (Vertical) | --- ### Key Electronic Functions #### 1. Common Mode Noise Suppression The primary purpose of the CMT1-6-R is to eliminate noise that is common to both the supply and return lines. By using two identical coils wound on a single core, it creates high impedance for common-mode signals while allowing desired differential signals to pass with minimal attenuation. #### 2. Magnetic Core Material It utilizes a **Ferrite core** material. Ferrite is chosen for its high permeability, which allows the component to achieve high inductance values in a compact physical footprint, making it ideal for low-frequency noise filtering. #### 3. High Current Capability Despite its high inductance, the CMT1-6-R is rated for up to 2.4 Amps. This makes it suitable for: * Switch-mode power supplies (SMPS) * DC-DC converters * AC line filters --- ### Physical Dimensions & Design The "R" suffix in the part number typically denotes **RoHS compliance**. The physical build consists of: * **Winding:** Dual windings for balanced filtering. * **Housing:** Open header or base mount for stability during through-hole soldering. * **Spacing:** Designed with standard lead spacing for easy PCB integration. --- ### Typical Applications * **Industrial Electronics:** Power quality improvement for factory automation. * **Telecommunications:** Noise reduction in data transmission power lines. * **Consumer Electronics:** Filtering in chargers and power adapters to meet FCC/CE emission standards.
