What are interference suppression capacitors needed for?
Interference suppression capacitors are used to reduce electromagnetic interference (EMI) in electrical circuits. This interference is caused by switching operations, motors or power supply units and can impair the function of other devices. Without effective interference suppression, signal errors, device malfunctions or even failures can occur. Especially in household appliances such as washing machines, refrigerators or vacuum cleaners, interference suppression capacitors prevent unwanted interference that is transmitted via the power supply or electromagnetic fields.
They are also indispensable in industrial applications such as switching power supplies or frequency converters to ensure electromagnetic compatibility (EMC). Film capacitors are particularly in demand in this area as they offer high dielectric strength and a long service life. The targeted placement of interference suppression capacitors in electrical circuits not only improves the functionality of the devices, but also complies with statutory EMC directives.

How do interference suppression capacitors work?
Interference suppression capacitors act as filter elements in electrical circuits. They dissipate high-frequency interference while allowing the desired operating current to pass through unhindered.
The way they work is based on the capacitance effect: the capacitor stores electrical charge for a short time and discharges it in a targeted manner in order to attenuate voltage peaks or interference signals. There are two main types: X capacitors are connected between the current-carrying lines (L and N), while Y capacitors work between phase and earth.
Film capacitors are particularly suitable for this purpose as they have a high insulation strength and a long service life. In power supply units, motor control units and industrial systems, they ensure that unwanted frequencies do not enter the power grid or adjacent circuits. This ensures a stable power supply and reduces interference that could otherwise lead to malfunctions or electromagnetic interference.

What types of interference suppression capacitors are there?
There are two main types of interference suppression capacitors: X capacitors and Y capacitors. X capacitors are connected between the phase (L) and neutral conductor (N) and protect against voltage peaks caused by loads being switched on and off. They are designed to absorb high surge voltages and at the same time have a long service life. Y capacitors, on the other hand, are located between the phase (L) and the earth (PE).
They prevent interference from being discharged via the housing of a device, which is particularly important for safety aspects. Both types must meet high safety requirements as they work directly with mains voltage. Film capacitors in particular have proven their worth as interference suppression capacitors, as they have a high dielectric strength and are mechanically stable. The choice of the right type depends on the application - there are optimized models for industrial control systems, household appliances or power supply units.

What happens if an interference suppression capacitor is defective?
A defective interference suppression capacitor can cause various problems. A failure often leads to electromagnetic interference, which is noticeable in the form of humming, malfunctions or an unstable power supply. With switching power supplies in particular, a defective capacitor can result in the device no longer starting or making annoying noises. In some cases, the capacitor bursts or shows discoloration, which indicates an overload or material fatigue.
X capacitors tend to lose capacitance over time, while Y capacitors can become a safety risk in the worst case if they no longer guarantee insulation to earth. Timely replacement is therefore important. When replacing them, high-quality film capacitors with a suitable dielectric strength should be used to ensure long-term reliability.
