Film Capacitors

Film capacitors are used in a variety of applications, from signal conditioning to filtering and power conditioning. They have become very popular in recent years due to their low parasitic inductance, high dielectric strength, and wide temperature range capabilities relative to other capacitors. The R75LN34704000K is a good example of a film capacitor, and is a common choice for applications that require a low-ESR solution with good high frequency performance.

What are Film Capacitors?

Film capacitors, also known as plastic film capacitors, are made up of a thin plastic film material as the dielectric, with aluminum or copper conductor electrodes wrapped around it. The resulting structure is then encased within a smaller cylindrical plastic body, with the conducting electrodes emerging at either end. The main advantage of film capacitors is their low parasitic inductance, making them the preferred choice for applications that require a low-ESR solution.

R75LN34704000K application field and working principle

The R75LN34704000K is a film capacitor used in a variety of signal conditioning, filtering, and power conditioning applications. It has a capacitance of 0.33 μF, with a tolerance of ±10%. It has a maximum operating temperature of 85°C and a maximum operating voltage of 18V AC or 100V DC. The operating temperature range is -40°C to +105°C. It is a non-polarized capacitor, meaning there is no need to worry about polarity when connecting it in a circuit.

The working principle of the R75LN34704000K is fairly simple. It functions like any other capacitor, storing and releasing energy in a circuit. When the capacitor is connected, it will serve as a short-term energy reserve, absorbing and discharging energy as it receives and releases electrical current. This creates a high-pass filter, which blocks out low frequencies while letting through high frequencies. This makes it a good choice for applications that require high-frequency signal conditioning and filtering.

Advantages of the R75LN34704000K

The R75LN34704000K offers a number of advantages. As a film capacitor, it has a low parasitic inductance which makes it ideal for applications that require excellent high-frequency performance. Additionally, it has a wide temperature range, from -40°C to +105°C, making it suitable for both indoor and outdoor applications. It is also non-polarized, meaning there is no worry of incorrect polarity. Finally, it has a maximum operating voltage of 18V AC or 100V DC, making it suitable for most power conditioning applications.
