Category Film capacitors

Product Description

In the modern electronics industry, capacitors, as basic components in circuits, undertake various functions such as energy storage, filtering, and coupling. Among the numerous types of capacitors, MPP (metallized polypropylene) film capacitors have gained widespread recognition for their excellent performance, especially in moisture-proof and flame-retardant capabilities.

I. Basic Characteristics of the MPP224J630VDC Capacitor

The MPP224J630VDC capacitor is a type of capacitor made using metallized polypropylene film as the dielectric material and aluminum foil or zinc-aluminum composite metallized film as electrodes. It is manufactured through processes such as winding, welding, and packaging. Its main characteristics include:

High Precision:The capacitor has a tolerance of ±5% or less, ensuring the stability and accuracy of the circuit.

High Voltage Withstanding:With a rated DC voltage of 630V, it can withstand high voltages and is suitable for high-voltage circuits.

Low Loss:It has low losses at high frequencies, making it suitable for high-frequency circuits. This helps reduce energy loss and improve circuit efficiency.

Long Lifespan:It features excellent self-healing capabilities, making it resistant to aging over long-term use and extending the lifespan of electronic devices.

II. Moisture-Proof and Flame-Retardant Characteristics of the MPP224J630VDC Capacitor

In electronic devices, moisture-proof and flame-retardant capabilities are two crucial safety features. In particular, in humid or high-temperature environments, if a capacitor cannot effectively resist moisture and fire, it may lead to serious consequences such as short circuits or fires. The MPP224J630VDC capacitor performs exceptionally well in these aspects, mainly due to the following factors:

Material Selection:Metallized polypropylene film itself has excellent moisture-proof properties, effectively preventing moisture penetration. Additionally, the material is inherently flame-retardant and does not easily ignite even at high temperatures.

Packaging Technology:Special packaging techniques, such as vacuum heat-sealing, further enhance the capacitor’s moisture-proof and flame-retardant capabilities. Vacuum heat-sealing removes air bubbles inside the capacitor, ensuring the dielectric layers are perfectly bonded, thus preventing moisture and air from entering the interior.

Housing Material:The capacitor’s housing is typically made of flame-retardant plastic materials, such as PBT (polybutylene terephthalate). These materials have high flame-retardant properties and do not easily burn at high temperatures, effectively protecting the internal components of the capacitor.

III. Moisture-Proof and Flame-Retardant Testing of the MPP224J630VDC Capacitor

To ensure that the MPP224J630VDC capacitor has excellent moisture-proof and flame-retardant performance in practical applications, a series of rigorous tests are usually conducted. These tests include, but are not limited to:

Humidity and Heat Test:The capacitor is placed in a high-temperature and high-humidity environment to simulate working conditions in a humid setting and to observe changes in its performance.

Flame Test:The capacitor is tested for flame retardancy according to relevant standards.

Voltage Breakdown Test:A gradually increasing voltage is applied across the capacitor until it breaks down to test its voltage-withstanding capability.

Through these tests, it can be ensured that the MPP224J630VDC capacitor has excellent moisture-proof and flame-retardant performance in practical applications, meeting the safety requirements of electronic devices.
