Produktbeschreibung

Produkteinführung

Metalized polypropylene capacitors has a series structure, metalized polypropylene film, low loss, outstanding electrical performance, high reliability, and self-healing capabilities, and can withstand high voltage and high current shock.

Als Leitelektroden werden bei metallisierten Kondensatoren winzige Aluminiumschichten (ca. 0,03 µm) auf die Isolierfolie aufgedampft. Bei einem Durchschlag verdampft die dünne Metallschicht um die Fehlerstelle durch den Kurzschlussstrom und es entsteht ein isolierender Bereich.

Stellen Sie das Multimeter so ein, dass es im Hochohmbereich zwischen 10 k und 1 m Ohm abliest, um den Kondensator zu testen. Verbinden Sie die Messleitungen – rot mit positiv und schwarz mit negativ – mit den entsprechenden Leitungen des Kondensators. Das Messgerät sollte bei Null beginnen und allmählich bis ins Unendliche ansteigen.

In diesem Artikel quantifizieren die Autoren die Verluste in Kondensatoren aus metallisierter Polypropylenfolie unter Verwendung eines analytischen Ansatzes. Das Konzept wird unter Verwendung von Kondensatoren mit unterschiedlichen Geometrien, aber gleicher Kapazität getestet. Um seine thermische Leistung zu maximieren, wird für jede Reihe von Kondensatoren eine Temperaturverteilung in der Rolle angenommen. Anscheinend erwärmt sich ein langer Kondensator schneller als ein identischer flacher Kondensator, der den gleichen elektrischen Belastungen ausgesetzt ist.

Es ist schwarz und die Kapazität beträgt 2,0 uF. Die Abmessung beträgt 38 * 28 * 18 mm. Metallisierte Kondensatoren sind mit unterschiedlichen allgemeinen Werten und Nennwerten erhältlich. Sie werden zur DC-Pulsation, Impuls- und Wechselspannungsreduzierung in Instrumenten, Messgeräten, Fernsehgeräten und elektrischen Haushaltsgeräten verwendet.

Metalized polypropylene capacitors have no polarity, high insulation resistance, excellent frequency characteristics (broad frequency response), and low dielectric loss. Based on the above advantages, film capacitors are widely used in analog circuits. Especially in the part where the signals are cross-connected, capacitors with good frequency characteristics and extremely low dielectric loss must be used to ensure that the signal will not be distorted when it is transmitted. High dielectric constant, small size, large capacity, good stability, suitable for bypass capacitors. Polystyrene film capacitors have low dielectric loss and high insulation resistance, but have a large temperature coefficient and can be used in high-frequency circuits.

Metalized polypropylene capacitors, often referred to as metallized polypropylene capacitors, are a type of capacitor used in electronic circuits. These capacitors are known for their excellent electrical properties and are commonly used in applications that require high precision and reliability. Here are some key characteristics and information about metalized polypropylene capacitors:

  1. Dielektrisches Material: These capacitors use polypropylene as their dielectric material. Polypropylene is a type of plastic that has low dielectric losses and is known for its stability over a wide range of temperatures and frequencies.
  2. Metallized Film: The polypropylene film is metallized by depositing a thin layer of metal, typically aluminum, on one or both sides of the film. This metallization process increases the capacitance and improves the capacitor’s performance.
  3. High Capacitance Values: Metalized polypropylene capacitors are available in a wide range of capacitance values, from picofarads (pF) to microfarads (µF). They can store a significant amount of electrical energy for their size.
  4. Low ESR and ESL: These capacitors typically have low Equivalent Series Resistance (ESR) and Equivalent Series Inductance (ESL), making them suitable for applications where low impedance and high-frequency performance are required.
  5. Low Losses: Metalized polypropylene capacitors have low dielectric losses, which means they can store and release energy efficiently without generating excessive heat.
  6. High Voltage Ratings: They are available in various voltage ratings to suit different applications, including high-voltage applications.
  7. Stable Performance: These capacitors offer stable and predictable performance over time, with minimal drift in capacitance or other electrical characteristics.
  8. Non-Polarized: Most metalized polypropylene capacitors are non-polarized, which means they can be connected to a circuit without regard to the polarity.
  9. Applications: These capacitors are commonly used in audio equipment, power electronics, filter circuits, and other applications where precision, low losses, and stability are crucial. They are also suitable for crossover networks in loudspeakers and in radio frequency (RF) circuits.
  10. Size and Form Factors: Metalized polypropylene capacitors are available in various package sizes, including radial and axial leaded capacitors, surface-mount capacitors, and even large can-style capacitors for high-power applications.

It’s important to select the right type and value of capacitor for your specific application to ensure optimal performance. Metalized polypropylene capacitors are often chosen for their reliability and low distortion in audio applications, as well as their ability to handle high-frequency signals in electronic circuits.
