Shielding filters use filtering components to filter the circuit, and use a shielded casing to shield external interference, filter out useless signals and noise interference in the circuit, and ensure excellent conduction filtering and radiation shielding properties of power and signals. Shielding filters are widely used in shielded rooms, shielded cabinets, and communication product filtering.

HBTE is committed to the research and development and production of shielding filter products in the field of communication. The application areas of the products cover radio wave darkrooms, shielded rooms, shielded cabinets, and shielded enclosures. Main products include shielded room AC power filters, shielded room DC power filters, shielded room signal filters, shielded cabinet AC filters, shielded cabinet DC filters, and shielded cabinet signal filters.

HBTE's shielding filters undergo relevant tests in accordance with the GJB1518A-2015 Radio Frequency Interference Filter General Specification. In the field of shielded rooms, they can provide a variety of power filters and signal filters with attenuation greater than 100dB within the stopband range of 10KHz-40GHz. The maximum operating current of the power filter can reach 200A, and the highest operating voltage can reach 380VAC. In the field of shielded cabinets, they can provide various power filters with shielding performance better than 80dB and signal filters with shielding performance better than 70dB in the communication working frequency band.
