Absorption magnetic ring, also known as ferrite magnetic ring, referred to as magnetic ring. It is a commonly used anti-interference component in electronic circuits, which has a good suppression effect on high-frequency noise.

During the test, we often encountered such a situation: although the design engineer connected a power filter to the power line of the equipment, the equipment still could not pass the "conducted disturbance voltage emission" test, and the engineer suspected that the filtering effect of the filter was not good. Constantly replace the filter, still can not get the desired effect.

Most of the magnetic rings need to be painted to facilitate the distinction. Generally, the iron powder core is distinguished by two colors.

According to the application of the inverter filter, it can be divided into the following types:

Any device capable of processing a signal can be called a filter. In modern communication equipment and various control systems, filters are widely used.

What are the differences between inverter filters and reactors? Let's take a look at it in detail.

As the name implies, the inverter filter is a special filter specially developed for the characteristics and laws of the harmonics generated by the inverter. It is an LC filter. Inverter Input Filter Overview Inverter filters are mainly passive components consisting of inductors, capacitors and resistors.

Although most inverter filters from manufacturers are equipped with internal interference suppression devices, in some applications the use of external EMC filters is still required. The two EPCSEMC filters are ideal for external applications to frequency converters. With the continuous expansion of the inverter market, fierce competition, cost pressure and technological innovation have led to a continuous decline in product prices and shrinking quantities.

Our company has the international advanced automatic magnetic material testing device and the most advanced domestic production line, mainly produces anti-interference magnetic core (filter magnetic core, iron powder core) series and inductance series two categories, a total of more than 300 kinds of specifications and models, all Products are in line with ROHS, REACH environmental protection requirements.

The power filter series products meet the requirements of UL, VDE, CQC and other safety certifications, and fully import ROHS and REACH environmental protection requirements. The product models and specifications are complete, including socket type, single-phase, three-phase, feed-through type, PCB board type and other styles of products. Tongjin can also design and manufacture according to the special requirements of customers.
