With the increasing of various electronic equipment, TV networks, switches, mobile communication equipment and office automation, the electronic systems in the electromagnetic environment is more and more complex and the electromagnetic interference (EMI) is more serious and becomes obvious obstacle for the system work. Electromagnetic interference (Electromagnetic Disturbance, the EMI) is defined as anything that might reduce performance for devices, equipment or system, or damage to the inanimate. Electromagnetic interference may be electromagnetic noise, useless signal or media changes.

Features

Posted in EMI Filter Series

The SE Series is 3 terminals filter produced base on multilayer chip capacitors. It’s more better to filter noise than capacitor at high frequency. Besides, one of characteristics is to endure high current and it’s more suitable to filter noise in DC power line and used in wide noise filter.

Application

Posted in EMI Filter Series

For direction and effects of Noise:
Bypass effect
①The entry of Noise, the reverse current occurs on ground conductor
②The electric charge can be easily imported to the ground, the bypass effect increase much.
③Will prevent noise

Inductor effect
The noise from③, the reverse current of grounding conductor occurs at the opening end
②from ground, the bypass effect decreased
The noise of inductors to①will reduce.

 

Parameters

Posted in EMI Filter Series

Cut off Frequency:
the barrier frequency when the output signal of system decreased largely (increased at band-pass filters). All of frequency will pass successfully under this frequency.
Max Working Voltage:
allowed Max. Voltage
Capacitance Value:
the measurement at test condition 1MHz
