The PCAQ3225A-142S is a Common Mode Choke/Filter with Surface Mount Device (SMD) configuration from PROD Technology. It measures 3.2 x 2.5 x 1.9 millimetres and is Compliant with the Restriction of Hazardous Substances (RoHS) Directive. It is designed to reduce common-mode noise (high frequency noise caused by Electro-Magnetic Interference, or EMI, coupling to the data lines) in device and system applications. It also helps protect against electrical overvoltage and noise generated by spikes on the power line. It has high-inductance and low-DC resistance. The PCAQ3225A-142S is suitable for use in medical, industrial, and consumer electronics applications. It is suitable for high-speed differential signal applications such as computers and peripherals, LCD monitors, fax machines, mobile phones, etc.
