DLP0NSC900HL2L

Common mode chokes are electronic components used to block the transmission of AC power between two nodes or circuits, while allowing DC current to pass. It is made by winding two or more windings of insulated wire on a ferromagnetic core, usually made of iron powder, ferrite or laminated steel strip. DLP0NSC900HL2L is a new generation common mode choke developed by SONG CHUAN Electronics, which has a wide range of application field and working principle.

The DLP0NSC900HL2L uses excellent-performance ferrite materials, and it filters out undesirable common mode noise from the signal line while the differential mode of the signal is undisturbed. With its excellent common mode attenuation performance, the DLP0NSC900HL2L is suitable for various high-speed differential signal lines.

The DLP0NSC900HL2L is mainly used in the automobile, industrial control and communication industries. Automobile industry is the mainstream of its application where it is used in engine control, restraint control, body control, and powertrain management, etc. In the industry control field, it is used to protect the device from surge, over-voltage, interference, make sure the device operate smoothly, stably and safely. And in communication fields, it is mainly used in both wired and wireless communication to reduce noise. Meanwhile, DLP0NSC900HL2L can also be used in power line communication (PLC) system, display control system and data processing system.

The DLP0NSC900HL2L has the following working principles:

1. High frequency common mode noise suppression: The common mode noise propagation speed is faster than the waveform impedance. DLP0NSC900HL2L high frequency common mode choke uses an iron powder core which can increase the high frequency common mode impedance. Signals with higher frequency have stronger interference, this type of choke can achieve a better filtering effect to directly reduce the common mode noise.

2. Low frequency common mode noise suppression: The core material used by DLP0NSC900HL2L can design various shapes, and the low frequency common mode resistance can be adjusted by the specific structure. The low frequency common mode signals have a greater noise impact, while this type of choke is designed for this purpose and can effectively suppress the low frequency common mode noise.

3. Differential mode interference suppression: The characteristic of differential mode interference suppression is related to the common mode characteristic. If the common mode impedance is high enough, the differential mode noise can be effectively suppressed. The DLP0NSC900HL2L has a structured design with a high common mode impedance in order to achieve a better differential mode noise suppression effect.

Connecting the DLP0NSC900HL2L to a differential line can effectively reduce the common mode noise in the line, which is the perfect EMC solution for power line system, automotive electronics system, and other industrial field.
