EMI/RFI filters are passive components that protect electronics devices by attenuating electrical noise. The EMIF02-USB04F3 is an EMI/RFI filter with an integrated USB Type-A connector. This filter is designed to protect against electromagnetic interference and Radio Frequency interference in electronic devices, such as computers and cell phones.

The EMIF02-USB04F3 is an unshielded four-channel filter with a low pass response. It is an external component that can be easily mounted to a USB port on a device. The filter features a frequency range of 2-4 GHz with an insertion loss of 6 dB maximum. The input impedance of the filter is 50 Ω, and the output impedance is 1 kΩ. The filter is designed with a range of impedance values so that it can work with different types of devices.

The EMIF02-USB04F3 has a wide application field and is used in a variety of electronic devices. It can be used in computers to protect against interference from external sources, such as power lines or cell phones. It can also be used in handheld devices, such as cell phones, to protect the device from radiation emitted by the device itself. The filter can also be used in industrial settings to protect sensitive equipment from EMI and RFI interference.

The EMIF02-USB04F3 incorporates a number of technologies to ensure its effective filtering. The filter is constructed from a combination of inductors, capacitors, and resistors, which form a low-pass filter. The filter creates a barrier between the electronic device and the source of interference, allowing only low-frequency signals to pass through. The filter also utilizes a means of impedance matching, i.e., the filter\'s input and output impedances are designed to match the signal from the device, allowing it to effectively filter out interference.

The EMIF02-USB04F3 is a versatile EMI/RFI filter. It is designed to provide effective protection from EMI and RFI interference for a range of devices. It is easy to install and can be used in a variety of settings. The EMIF02-USB04F3 is an effective and reliable filter for protecting electronic devices from EMI and RFI interference.
