Common Mode Chokes are a key component in electronic applications, and are often used to cancel out electromagnetic interference (EMI) and radio frequency interference (RFI) from different currents and signals in a circuit. The DLP11RB400UL2L is the designation for a particular type of Common Mode Choke manufactured by Delta International Limited. This choke provides excellent electrical performance characteristics for noise and EMI suppression applications. It is RoHS compliant, UL Recognized, and also meets most current EMI/EMC standards.

The DLP11RB400UL2L is a one-line common mode choke which has a built-in ferrite core structure that enables it to reduce differential and common mode noise and current. This choke offers good attenuation of high frequency noise currents and also reduces disturbances caused by EMI/EMC sources such as switching devices, motors, and computer systems. It has a rated current of 2.1A, a rated frequency of up to 400MHz, and a capacitance of up to 0.2pF. The temperature range for the DLP11RB400UL2L is -40°C to +85°C.

The DLP11RB400UL2L is suitable for use in a wide variety of applications, including signal lines of digital devices, analog signal lines, and switching power circuits. It can also be applied to different high frequency automotive systems such as signal and control lines, radio frequency transceiver systems, and instrumentation systems. Applications of this helical choke include noise suppression of automotive controllers, audio and visual equipment, telecommunications systems, and instrumentations.

The working principle of the DLP11RB400UL2L is based on the concept of inductance. It is composed of an insulated conductor that is wrapped around a ferrite core, and the induced current or voltage passes through the inductor is proportional to the rate of change of the magnetic flux. As the current or voltage through the core changes, the permeability of the core alters, therefore inducing voltage in the winding of the inductor. This creates a "magnetic cloaks” around the core, causing high frequency and low-frequency noise to be suppressed, allowing signals within the circuit to be undistorted and more stable. This choke also exhibits excellent thermal stability for its rated temperature range.

The DLP11RB400UL2L is a powerful tool in noise suppression applications, providing good attenuation of high frequency noise currents. Its wide range of applications, excellent electrical performance characteristics, robust build and temperature stability make this choke a great choice for a variety of noise suppression needs.
