Common Mode Chokes are electromagnetic components used to suppress or divert the flow of common mode currents in a signal path. The DLP11SA900HL2L is a common mode choke that features anti-birthday, anti-saturation characteristics, a 9.8uH inductance, and a maximum DC current of 450mA. The DLP11SA900HL2L also offers a 900mA rohs compliant current rating, a low DC R feature of 0.3mOhm, and an operating temperature range of-40C to +130C.

The primary application field of the DLP11SA900HL2L is as a filter for EMI noise suppression in power and communication circuitry. The choke also can be used in general signal and power distribution and conditioning systems, where it provides an effective way to reduce electrical noise and interference. In particular, this product is useful in applications that require low insertion losses and high common mode impedance control.

The working principle of the DLP11SA900HL2L is based on the inductive nature of a common mode choke. A common mode choke has a pair of windings with the same number of turns, which are connected in series with each other. At high frequencies, the choke acts as an inductor, and any current flowing through the windings will induce a magnetic field. This field will then oppose any change in current travelling through the windings. This effect is called inductive reactance, which is the choke’s ability to reduce the flow of common mode currents. As a result, the choke acts as a low-pass filter, allowing only low frequency signals to pass through.

In addition to reducing EMI noise, the DLP11SA900HL2L also helps to provide a wide range of power and communication related signal conditioning functions. It can be used to control signal integrity and match line impedances, as well as to reduce signal distortion and crosstalk. It is also useful in signal isolation applications, providing a means to reduce common mode currents while eliminating ground loops.

The DLP11SA900HL2L is an ideal choice for a range of power and communication circuit applications, and it is a reliable and effective way to reduce the effect of common mode interference and noise. With its anti-birthday and anti-saturation characteristics, its low DC R feature of 0.3mOhm, and its ability to operate in temperatures ranging from -40C to +130C, the DLP11SA900HL2L is an attractive option for any system requiring the reduction of common mode noise.
