Capacitors for Induction Heating of high & medium frequencies

What are the characteristics of capacitors for medium- and high-frequency induction heating?

Capacitors for medium- and high-frequency induction heating are special electrical capacitors used in heating systems based on electromagnetic induction. These devices are designed to operate in systems that generate high frequencies (typically from a few kHz to MHz) and use electromagnetic induction to generate heat in metal objects. This means they must be adapted to work in demanding conditions, often at high temperatures and in the presence of strong electromagnetic fields. Therefore, selecting the right capacitors is crucial for the effectiveness and reliability of such heating systems. Exactly such products are available in our offer.

How to choose capacitors for medium- and high-frequency induction heating?

As mentioned earlier, capacitors used in induction heating operate in very demanding conditions. Therefore, the following aspects should be considered:

• operating frequency – capacitors should be selected according to the frequency range characteristic of a given induction heating system. This is why high-quality MKP (polypropylene) or MPP (metallized polypropylene) capacitors are often used in such applications,
• rated voltage – it must be appropriate for the operating voltage in the specific heating system, high enough to avoid damage to the capacitor,
• capacitance – it is essential to choose a variant with sufficient capacitance to store the required amount of electrical energy,
• long service life – models known for long-term stability and long operational lifetime should be chosen to reduce the need for frequent component replacement. Exactly such capacitors for medium- and high-frequency induction heating are available in our offer,
• standards and certifications – they help ensure that the manufacturer pays close attention to these crucial factors.
