Common Mode Chokes (CMCs) are used to reduce the amount of noise in electrical systems. Many industries use CMCs for this purpose, such as telecom, automotive, and aerospace. The DLW21HN121HQ2L is a common mode choke with a wide range of applications and benefits.
The DLW21HN121HQ2L is a common mode choke designed to suppress noise in a wide variety of conditions and applications. This choke can provide as much as 120dB of differential-mode attenuation at frequencies up to 10 MHz, and can be used for applications involving a wide range of voltages and currents. It can also be used in both AC and DC circuits.
The main application field for DLW21HN121HQ2L CMC is for noise suppression in power electronic systems. These include switching power supplies, voltage converters, motor control systems, and motors. It can also be used to reduce EMI emissions in automotive, telecom, and aerospace systems. In addition, DLW21HN121HQ2L can be used in medical imaging systems to reduce noise in high-frequency imaging systems.
The working principle of DLW21HN121HQ2L is based on the concept of impedance mismatch. The choke contains two inductor elements that are designed to restrict the flow of noise energy by presenting an impedance mismatch to common-mode signals. By using this mismatch, the choke creates an impedance barrier between the interfering noise and the desired signals. This helps to reduce the amount of noise that is transmitted, and allows the desired signals to be received with little interference.
The DLW21HN121HQ2L is a compact and versatile CMC designed to reduce noise in a variety of applications. It is designed to provide up to 120dB of differential-mode attenuation and can be used with both AC and DC circuits. Its main applications are in power electronic systems to reduce noise in switching power supplies, voltage converters, motor control systems, and motors. Additionally, it can also be used to reduce EMI emissions in automotive, telecom, and aerospace systems, as well as in medical imaging systems.
