EMI 25a low-pass filter, electromagnetic audio decoder amplifier

Features: Power supply noise is a form of electromagnetic interference with a frequency spectrum approximately between 10 kHz and 30 MHz, with a maximum amplitude of up to 150 MHz. The electromagnetic interference (EMI) filter suppresses both series and common-mode interference. This product is widely used in precision measuring instruments, building automation, precision machinery and equipment, elevators, automated lighting systems, communication equipment, UPS switching power supplies, automotive electronics, and other equipment. The EMI filter is a reactive low-pass filter installed at the power input of electronic equipment. Specifications: Secondary filter dimensions: approximately 28 mm wide x 98 mm long x 19 mm high / 1.1 x 3.86 x 0.75 inches. Material: Metal. Note: The selection of the EMI filter should take into account its operating voltage, operating current, and withstand voltage. EMI filters should be installed at the power input to reduce radiated interference. It is recommended to use a double-soldered cable for connecting the EMI filter, as this helps eliminate some high-frequency interference signals. The input and output lines of the EMI filter must not be parallel, and a certain distance must be maintained to ensure proper operation. The electrical point (E) of the EMI filter must be in direct contact with the chassis and connected to ground. Package contents: 1 EMI filter
