Film capacitors, also called foil capacitors or plastic film capacitors, are non-polarized discrete capacitors. Consisting of an insulating sheet of polypropylene, polyester, or polycarbonate film dielectric sandwiched between two metal electrodes, they offer excellent electrical characteristics and stability over a wide temperature range. They are lightweight and offer superior dimensional stability, making them an ideal choice for high-frequency applications. The 50MU333MZ22012 series of film capacitors is designed for use in applications that require precise and reliable RF performance.

50MU333MZ22012 application field and working principle

The 50MU333MZ22012 series of film capacitors are typically employed in a wide variety of commercial and aerospace applications that require high electrical performance, minimal temperature drift, and exceptional hermeticity. These capacitors are suitable for amplifiers, RF transmitters, switches and timing circuits. They can also be used in power supplies, electronic ballast circuits, precision circuits, and motor controls.

The 50MU333MZ22012 series of capacitors are constructed in a hermetic package, which offers superior leakproof performance and long-term stability. This allows the capacitors to operate reliably in extreme temperatures and in humid conditions. The nickel-plated aluminum can withstand high temperatures up to 180oC and offers excellent mechanical strength against shock and vibration. The use of high-grade sandwiched film dielectrics provides excellent voltage and current characteristics. These capacitors offer an excellent thermal coefficient of capacitance and low inductance for superior performance.

The working principle of the 50MU333MZ22012 series of film caps is simple. The capacitor is formed by two parallel metal plates, separated by an insulating dielectric. The plates are insulated from each other and connected to circuit traces outside the package. The voltage across the plates creates an electric field inside the dielectric, which stores energy. When a current runs through the capacitor, energy is stored in the form of electrical charge on the electrodes. This stored energy is then returned to the circuit when the current reverses direction.

The 50MU333MZ22012 series of capacitors offer a wide range of capacitance ratings from 100pF to 0.1µF. They are available in several sizes and shapes, and have a wide operating temperature range, from -55°C to +105°C. The capacitors have an industry-standard leaded construction that is designed for hand soldering. They offer excellent voltage breakdown, current leakage, and low ESR and ESL values. The capacitor also features excellent self-healing and arc suppression performance, making them suitable for extended high-voltage pulse operations.

In conclusion, the 50MU333MZ22012 series of film capacitors offer superior electrical performance and are suitable for a wide range of commercial and aerospace applications that require high frequency operation and precise RF performance. The use of hermetic packages ensures leakproof operation and excellent long-term stability. The capacitors offer a wide range of capacitance ratings and have excellent electrical characteristics, making them an optimal choice for high-frequency circuits.
