Common mode chokes offer a useful tool for controlling the flow of currents in certain electronic devices. The DLW5BSZ801TQ2L is an example of such a component, designed to provide filtering and impedance matching for high-speed differential signals in a wide range of applications. This article will explore the application field and working principle of the DLW5BSZ801TQ2L.

Application Field of the DLW5BSZ801TQ2L Common Mode Choke

The DLW5BSZ801TQ2L is a ferrite-based common mode choke designed for use in a variety of high-speed and high-frequency signal applications, including power supplies, RF systems, and high-speed data lines. It is capable of carrying many times its rated current without experiencing significant core saturation, making it ideal for applications that require robust filtering and high EMI suppression. Additionally, the DLW5BSZ801TQ2L is highly resistant to temperature and humidity, and is suitable for operating temperatures up to 125°C.

The DLW5BSZ801TQ2L is available in two standard package sizes, 8 mm x 8 mm x 5 mm and 10 mm x 10 mm x 5 mm, and can be used in either a through-hole or surface mount configuration. It is also rated for up to 1,150 V isolation and up to 20 A rms at 1 MHz, making it suitable for both high voltage and high current applications. It is available in both single and double-ended versions, with an impedance range of 2.2 to 12.5 µH.

Working Principle of the DLW5BSZ801TQ2L Common Mode Choke

The DLW5BSZ801TQ2L is a common mode choke designed to suppress common mode current and minimize EMI radiation. This is achieved by using a three section Ferrite core that is magnetically loaded to provide both high inductance and high common mode impedance. The core is then wrapped with two high-frequency windings in opposite directions, so that the two signals pass through the choke in opposite directions. When passing through the core, the common mode current is suppressed due to the increased inductance, while the differential modes remain unaffected.

The DLW5BSZ801TQ2L is designed to provide uniform inductance in both differential and common modes, allowing it to provide uniform filtering and impedance matching for high-speed differential signals. It is also capable of efficiently suppressing common-mode noise and reducing EMI radiation over a wide frequency bandwidth. Additionally, the DLW5BSZ801TQ2L is able to provide high current filtering while keeping the overall size of the component to a minimum.

Conclusion

The DLW5BSZ801TQ2L common mode choke is a useful tool for controlling the flow of currents in certain electronic devices. Its small size, high current capabilities, and temperature and humidity resistance make it ideal for use in a variety of high-speed and high-frequency signal applications. Additionally, its ferrite-based core allows it to efficiently suppress common-mode noise and reduce EMI radiation over a wide frequency bandwidth.
