1. Ensure the filter operates reliably under high-voltage conditions; 2. The filter must have a shielding structure, with the shielding box cover and body having a good electrical contact. The filter's capacitor leads should be as short as possible, using short-lead low-inductance through-core capacitors; 3. When the filter is continuously supplied with rated current, its temperature rise must be low to ensure that the performance of the filter's components is not compromised during continuous operation at the rated current; 4. Clearly define the operating frequency and the interference frequencies to be suppressed. If the two frequencies are very close, a filter with a very sharp frequency characteristic is required to separate the two frequencies; Aviation ground power 2, 36V aviation power 1, 400HZ variable frequency power supply 7, 115/200V power supply 2, 27V DC power supply 5, 400HZ power supply 12, aviation power supply.
5. High work reliability is essential as faults in filters designed to shield against electromagnetic interference are often more challenging to locate than those in other components. 6. To ensure that the filter's frequency characteristics align with the designed values during operation, the signal source impedance and load impedance connected to it must match the specified values during design.
