EMI-12 Filter
Function: Suppresses electromagnetic and radio frequency interference (RFI/EMI) in AC/DC power lines or signal lines.
Filter Type: Typically a low-pass filter that allows low-frequency signals while blocking high-frequency noise.
Circuit Components:
- Inductors (Chokes): Provide impedance to high-frequency noise.
- Capacitors: Shunt unwanted signals to ground (often X and Y capacitors are used).
- Resistors (Optional): Used for damping oscillations.
Voltage Rating: Commonly ranges from 125V to 250V AC/DC, depending on the model.
Current Rating: Typically rated for 1A to 20A or more, depending on the power requirements.
Frequency Range: Effective at filtering frequencies from 10 kHz to several GHz.
Insertion Loss: Measured in dB, indicating how much noise is attenuated at specific frequencies.
Mounting Type:
- PCB-mounted (for compact electronic designs)
- Chassis-mounted (for larger industrial applications)
- DIN-rail mounted (for control panels and automation systems)
Operating Temperature Range: Typically -40°C to +85°C, depending on construction.
Certifications: Can be UL, CE, or RoHS compliant, ensuring safety and environmental standards.
