Technical Specifications

The TRTEP7S-U675A013 has a specific common mode impedance at a certain frequency (typically 100 MHz). It also has a rated current, DC resistance, and isolation voltage. The inductance value is a key parameter for determining its effectiveness in suppressing common mode noise. It is available in a surface mount package for easy integration into printed circuit boards. Detailed specifications, including impedance vs. frequency curves and mechanical dimensions, are available in the TDK datasheet for this part.

Common mode chokes work by presenting a high impedance to common mode currents while allowing differential mode currents to pass through with minimal attenuation. This effectively blocks common mode noise from entering or leaving the circuit. The selection of a common mode choke depends on the frequency range of the noise to be suppressed, the current carrying capacity required, and the physical size constraints of the application. Proper grounding is also essential for the effective operation of a common mode choke.
