Common Mode Chokes are a type of electrical transformer widely used for preventive and corrective purposes when faced with differential-mode interference or common-mode interference. While differential-mode interference creates interference among the equal-phase power leads and is caused by a fault or improper load, common-mode interference is the result of an imbalance in the power leads and comes from leakage.The DLW5BTH102TQ2L common mode choke is a two line filter designed to address common output mode noise interference found in audio and other sensitive communication devices. Its design is comparable to that of a regular transformer used for power line isolation. However, this two line filter uses two bypass coils that are wound in an opposite direction, which allows this choke to filter out both differential and common-mode interference. Its main application field includes offline SMPS, inverters, telecom, and general audio-visual equipment, among other devices.The working principle of the DLW5BTH102TQ2L common mode choke is relatively simple. Incoming current passes through the two lines, and each line has one bypass coil and two cores: one in the positive line and one in the negative line. When the common-mode interference occurs, the two coils will generate opposing flux directions that counteract the interference, thus damping the loop between the two common terminals. As such, the interference is eliminated while measureable current passes into the opposite terminals.The other advantages of the DLW5BTH102TQ2L common mode choke filter include extremely low leakage inductance and an improved differential mode size with fewer cores which results in a much smaller form factor than traditional filter solutions. Such low size and high damping force make this filter suitable for a wide range of offline applications, including audio and telecommunications. The superior filtering capability of this choke can reduce high-frequency noises found in electric power by up to 40 dB in 2-line systems.In addition, the DLW5BTH102TQ2L two line filter is also perfect for AC or DC applications. It is also unaffected by high operating temperature and is capable of operating at frequencies as high as 1.3GHz with very low insertion loss. Moreover, due to its multi-layer construction, it is able to provide better EMI/RFI performance.All in all, the DLW5BTH102TQ2L common mode choke is a extremely portable and powerful noise suppressor for preventing different-mode and common-mode interference in audio and other sensitive communication devices. It offers superior filtering capabilities and is capable of operating at a wide range of temperatures and frequencies. Additionally, its small form factor and low leakage inductance ensure that the device is both energy efficient and effective in providing superior signal-to-noise ratio.
