SBSPP0500333MXB

EMI/RFI Filters (LC, RC Networks)

SBSPP0500333MXB is an electromagnetic interference (EMI)/Radio Frequency Interference (RFI) filter (RC, LC networks) that provides balanced EMI/RFI interference suppression when utilized for AC and DC circuit protection.

Application Field

The SBSPP0500333MXB is used for AC and DC applications in a wide range of EMI/RFI suppression needs, including in a wide variety of industrial, commercial, automotive, and consumer products. It is especially suitable for preventing radio interference interference (RFI) radiation or conducted (emi) emissions from reaching and affecting other components, or other electronic devices by reducing the amount of interference coming through the filter. Filter applications include:

• Fax machines
• Computer power supplies
• Printers
• HVAC systems
• Mobile phones
• Other communication systems

Working Principle

The SBSPP0500333MXB works by blocking the interference and/or noise on the line from passing through to other connected devices. This is accomplished by a combination of low pass (LP) and high pass (HP) filters that are designed to attenuate or reject noise frequencies within the range which is most common for consumer electronics. This range is typically 30 kHz to 500 kHz. The filters also implement Common-Mode and Differential-Mode rejection to reduce the level of applied noise.

The filter is designed to reject most of the radio frequency interference (RFI) and electromagnetic interference (EMI). RFI is the higher frequency signals which are generated by different electronic devices, while EMI is the relatively low frequency signals which are generated by power sources. The filter is also designed to reduce noise or other interference that might be picked up on the line from external sources.
