DOREXS provides a variety of EMI filter options from ordinary to customized EMI filters, aiming to significantly reduce market costs and give contractors a greater advantage in the competition. These EMI/EMC filters have demonstrated good stability and reliability in many practical applications and are very suitable for use in military equipment.
High frequency differential mode insertion loss. The commercial service standard has a low limit of 150kHz for transmission and the UK FCC requires a low limit of 450kHZ. As a result, commercial service filters only have to ensure filter characteristics around 150kHz. The low frequency limit of the military power supply filter is 10kHz. If the output power of the power transformer is low, the experiment will not succeed.

These filters are designed with high precision and reliability to withstand extreme temperatures, high voltages, and harsh line conditions. Key features of military filters include superior durability, stable performance, and the ability to provide long-term protection in harsh environments. By selecting the right filter solution, military organizations can ensure the safety, operational readiness, and service life of their equipment to support successful missions in a variety of applications.
Why use EMI filters on military equipment?
In modern warfare, the use of electronic equipment has become an important part of military operations. However, in complex environments, military equipment is often prone to severe electromagnetic interference, thus affecting combat effectiveness. Therefore, it is particularly important to suppress EMI in military equipment.
First of all, whether it is communication equipment, radar systems or navigation systems, they all need to maintain stable operation in complex electromagnetic environments.
Secondly, in military operations, the stability, reliability and security of signal transmission are crucial. In addition, in radar systems, the accuracy of reconnaissance, surveillance and target tracking directly affects judgment in action.
In summary, the application of EMI filters in military equipment is indispensable. It can effectively ensure the stability and reliability of the equipment, and can also ensure the safety and stability of signal transmission.

EMI Challenges in Military Electronic Systems
With the increasing intelligence of weapon systems and the widespread use of high-frequency and high-speed electronic equipment, military platforms are facing increasingly stringent challenges in electromagnetic interference (EMI) and electromagnetic compatibility (EMC):
⦁ Multiple systems operate in coordination, which is prone to crosstalk and false signal interference
⦁ High-power pulse equipment coexists with sensitive communication modules, which is prone to interference
⦁ Extreme environments require extremely high reliability of filters (temperature, vibration, shock)
⦁ Military standard certification requirements (such as MIL-STD-461) are strict, and ordinary filters are difficult to pass
