1.8mH Toroidal Inductor Common Mode Choke with Enameled Copper Wire for SMPS Noise Suppression

The T22148-1.8mH Toroidal Inductor is a common mode choke engineered for noise suppression and electromagnetic interference (EMI) filtering in switching power supplies (SMPS) and other power electronic applications.

Built around a toroidal magnetic core with enameled copper wire windings, this inductor is designed to attenuate common-mode noise and help improve electromagnetic compatibility (EMC) in electronic circuits.

Its compact toroidal construction makes it well suited for integration into PCB-based power supply systems, industrial electronics, and a wide range of electrical equipment requiring dependable EMI filtering solutions.

• 1.8mH InductanceWith a specified inductance of 1.8mH, the T22148 common mode choke is intended for noise-filtering applications where common-mode interference must be controlled.
• Effective Common Mode Noise SuppressionDesigned to attenuate unwanted common-mode electrical noise, helping reduce conducted electromagnetic interference in switching power supply circuits.
• Enameled Copper Wire WindingsManufactured with insulated enameled copper wire, providing electrical insulation between winding turns and supporting reliable operation in power electronic applications.
• Toroidal Core ConstructionThe ring-shaped magnetic core provides an efficient magnetic path and supports a compact winding structure suitable for PCB integration.
• Through-Hole PCB InstallationEquipped with metal terminal leads for through-hole mounting, allowing straightforward integration into compatible printed circuit board assemblies.
• Suitable for SMPS EMI FilteringDesigned for use in switching power supplies and related electronic equipment requiring common-mode noise suppression.

The T22148-1.8mH Toroidal Common Mode Choke can be considered for the following applications:

• Switching Mode Power Supplies (SMPS): Common-mode EMI filtering in AC/DC power conversion systems.
• Industrial Power Equipment: Noise suppression in compatible industrial electronic power circuits.
• LED Power Supplies: EMI filtering in suitable LED driver and lighting power supply designs.
• Home Appliance Power Circuits: Common-mode interference reduction in electronic appliance power modules.
• Power Supply EMI Filters: Integration into common-mode filtering stages designed to reduce conducted noise.

For electronic equipment manufacturers and power supply designers, selecting the right common mode choke is an important part of EMI filter design.

The T22148-1.8mH combines a toroidal core structure with enameled copper windings, making it a practical component to evaluate for common-mode interference suppression in switching power supplies.
