LINES 56KB
How do EMI filters work? Most electromagnetic noise is in a higher
frequency range, so EMI filters are often low-pass filters that
sift out high frequencies while letting lower frequencies pass
through. Different EMI line filters suppress specific frequencies
of noise, while allowing others to flow unimpeded. After the
filtering process, electromagnetic noise gets diverted away from
the device and to the ground. Some EMI filters may also route
unwanted currents back to the noise source or absorb them.

| 18GHz~40GHz≥80dB |
type | Rated voltage | Rated current | wires | Pass band | application |
| SF-56KB | 200VDC | 1A | 2 | 4KHz | telephone/fax/AC/DC switch signal |
| SF-V8 | 250VAC | 1A | 8 | 7KHz | internet |
| SF-V2 | 100VDC | 1A | 2 | 6MHz | fire alarm/Entrance guard/video |
| SF-K2 | 250VDC | 2A | 2 | 100KHz | Air-condition/fire alarm/entrance guard/broadcast |
EMI filters Applications:
- Single-phase: Single-phase EMI filters are effective for smaller
equipment, such as home appliances and electronics, as well as
industrial applications, such as food service equipment, power
supplies and telecommunications. Single-phase EMI filters can also
be compatible with fitness equipment and motor controls.
- Three-phase: For more stringent EMI suppression, three-phase EMI
filters can block higher levels of noise through a three-stage
filtering system. Three-phase EMI filters are for use in high-power
applications such as industrial machinery and motors, medical
equipment, test equipment and industrial tools.
