The Greatest Advantages of Film Capacitor

Recently we received RFQ from our customers about film capacitors. We UF Capacitors supply metallized polyester film capacitor, Both THT dip type and Box-type available, CL21 Series, CL21B series, We also produce metallized polypropylene film capacitors , CBB21 series, CBB21B series, also high voltage series CBB81 series. For audio customers, we have premium metallized polypropylene  film capacitors like MPX series, PAC series.  

Why is that film capacitor so popular? What are the greatest advantages of film capacitors.

There’re some traits below that attracts buyers

1. Stability

Film capacitors exhibit excellent stability over temperature, frequency, and voltage. This stability makes them ideal for applications requiring precise and consistent capacitance values over a wide range of operating conditions.

2. Low Dissipation Factor
3. Film capacitors typically have low dissipation factors, which means they have low energy losses and are efficient at storing and releasing energy. This property is beneficial in applications where minimizing power losses is critical.
4. High Insulation Resistance

Film capacitors offer high insulation resistance, making them suitable for applications requiring high reliability and long-term performance. They are less prone to leakage currents, which can improve the longevity of the capacitor and the overall reliability of the circuit.

5. Low Dielectric Absorption

Film capacitors have low dielectric absorption, meaning they can quickly discharge and recharge without retaining significant charge. This property is advantageous in applications requiring fast response times or rapid charge/discharge cycles.

6. Wide Operating Temperature Range

Film capacitors can operate effectively over a wide temperature range, making them suitable for use in harsh environments or applications where temperature fluctuations are common.

7. Self-Healing Properties

Certain types of film capacitors, such as metallized polyester and metallized polypropylene capacitors, have self-healing properties. If the dielectric material is punctured or damaged, the capacitor can partially heal itself by forming a new dielectric layer, maintaining its functionality and preventing catastrophic failure.

 

We find a few common encountered values for film capacitors as below.

1. 0.1uF Film Capacitor (104)

This value is quite common for decoupling and bypassing applications, especially in digital circuits where stability and noise suppression are essential.

2. 1uF Film Capacitor (105)

Another frequently used value, particularly for filtering applications in audio circuits and as coupling capacitors in amplifier circuits. They strike a balance between size, capacitance, and performance.

3. 10uF Film Capacitor (106)

Used in various applications where larger capacitance values are needed for filtering and energy storage. They are commonly found in power supply circuits and voltage regulation circuits.

4. 100uF Film Capacitor (107)

While less common than the previously mentioned values, 100uF capacitors find use in power supply filtering, smoothing, and voltage regulation, especially in higher power applications.

5. 1nF Film Capacitor (1000pF)

For more precise applications, such as in timing circuits or RF (radio frequency) applications, smaller capacitance values like 1nF are frequently utilized.

 

For MPX audio capacitor and PAC audio capacitor, we supply reliable quality to replace Erse PulseX series; Mundorf - MCAP MKP, Jantzen Audio, Mallory,  SCR / SOLEN, Auricap High Resolution, Audyn Cap Plus FOIL,INTERTECHNIK, Ampohm etc with faster lead time 4 weeks and more competitive price.
