Its small snap-in design and low inrush current makes it easier to install, and ensures secure mounting. It is also resistant to fire, and UV exposure.

Working Principle of the 761M33594-189

At the core of the 761M33594-189 is its principle of operation. This film capacitor works on the principle of the condenser, which is that two metal plates are separated by a dielectric material (in this case an insulating film). This capacitance causes the charge to build up on each metal plate, with the voltage between them intensifying. This basic principle allows the 761M33594-189 to act as a conductor for alternating current, while simultaneously blocking DC.

In the capacitor, the electric field is created when a voltage is applied to the plates. This produces an electric displacement quality, which increases the capacity of the capacitor. As it can store energy, it can be used to filter out any alternating current that passes through it. This filter is able to change the frequency components of the signal, allowing only certain components to pass through, while rejecting and dampening others. The aforementioned process is known as a ‘passive low-pass filter’, and the 761M33594-189 is generally used in this fashion.
