Electromagnetic interference poses one of the most serious dangers to your electric device. A proper electric noise filters will ensure their safety, as well as the safety of other devices in the same network. Protect your equipment and meet the legal standards for device safety by purchasing one of ours!

 

Ensure that your electronic devices work unimpeded by sudden surges in the power lines. By choosing the right filter, you keep the EMI hazard to a minimum!

Shield Your Equipment Properly With an Electric Noise Filter

Having a good filter is necessary for two reasons. First of all, it prevents the noise from interfering with a piece of electronic equipment, thus reducing the risk of its malfunction or the degradation of its capacities. In this regard, it serves as the first line of defence.

But it's not just a single piece of equipment that the filter protects, but all of the other devices sharing the same network. A good filter will prevent the noise from leaking further into the power lines and make sure that your device poses no hazard to others.

International regulatory bodies have set strict rules with regards to the amount of electrical noise a piece of equipment is allowed to emit into the power line. The built-in filter that most of the contemporary equipment features tends to meet those limits in ideal laboratory conditions. Real-life uses, however, often demand more than those basic filters can provide. It is therefore necessary to introduce another.

AC Electronic Noise Filters

AC – based equipment, whether analog or digital, is bound to benefit from our filters of the JETAF series. High insertion loss capabilities and great temperature stability, made possible with the use of amorphous nanocrystal line cores – those are the main perks of our AC filters.

Add to that efficient heatsink or convection cooling and a great longevity with the mean time between failure being between 200 000 – 400 000 hours, and you've got a filter that you can rely on in the majority of private, commercial and industrial uses.

Before purchasing, please check the datasheet of each of our individual filters for more information.

To assure the best performance, we advise combining our filters with AC/DC power supplies that we manufacture as well. Browse through some other equipment on our offer and make your choice!

Electrical Noise Filtering Devices for DC Networks

For reliable DC filters, look no further than our JETDF series. These compact devices have an even greater thermal resistance than the AC filters, while sharing all of their perks. They are also somewhat smaller in size, making them

Again, you should consider pairing these with our DC/DC power supplies to truly ensure maximum performance.

Line Noise Filters With Great Insertion Loss

As most electric noise comes as a high-frequency signal, the purpose of the filter is to let through only the signals with a lower frequency. How well does it manage to do that is measured by what is called the insertion loss. The insertion loss (output/input signal ratio) is counted in decibels and varies according to frequency range.

The attenuation capacities of our filters are as follows:

Single-phase AC JETAF filters:

Frequency

Insertion loss

0.15 – 0.3 MHz

≥20 dB

0.3 – MHz

≥ 35 dB

1 – 10 MHz

≥ 55 dB

10 – 30 MHz

≥ 50 dB

Three-phase AC JETAF filter:

Frequency

Insertion loss

0.15 – 0.3 MHz

≥ 55 dB

0.3 – MHz

≥ 60 dB

1 – 10 MHz

≥ 30 dB

10 – 30 MHz

≥ 20 dB

DC JETDF filters

Frequency

Insertion loss

0.15 – 0.3 MHz

≥ 15 dB

0.3 – MHz

≥ 35 dB

1 – 10 MHz

≥ 55 dB

10 – 30 MHz

≥ 50 dB

Electrical noise reduction should be one of your prime concerns. Sometimes a functioning equipment can be a literal life and death matter – in medicine, for example. Make sure to pick a reliable filter for your industry.

Remember That Power Noise Filters Are Just a Part of Your Equipment's Protection

There are many types of electromagnetic interference with varying origins – both man-made and natural. Electronic device congestion, noise generated from switch-mode power supplies, lightning and much more – the list of potential dangers to your equipment would take up quite the space.

An electric noise filter serves primarily as a protection against conducted interference, meaning the interference that is transmitted through power lines, no matter its origin.

However, your equipment can be further exposed to radiated interference from the outside, to which a filter can offer only a limited protection. Therefore, if you're indeed serious about safeguarding your devices from all potential hazards, you shouldn't neglect the proper shielding either.
