Impedance characteristics (120Hz) Z(-25℃)/Z(+20℃)^5 ; Z(-40℃)/Z(+20℃)^8
Insulation resistance The value measured with a DC500V insulation resistance tester between all terminals and the insulating sleeve on the container cover and the fixed strap installed is ≥100MΩ.
Insulation voltage There was no abnormality when a voltage of AC2000V was applied for 1 minute between all terminals and the insulating sleeve on the container cover and the fixed strap installed.
Durability In an environment of 105°C, the rated ripple current is superimposed without exceeding the rated voltage. The rated voltage is continuously loaded for 3000h and then returned to 20°C. The test should meet the following requirements.
Capacity change rate (△C ≤±20% of initial value
Loss value (tg δ) ≤200% of initial specification value
Leakage current(LC) ≤Initial specification value
High temperature no load characteristics After being stored in an environment of 105℃ for 1000 hours and then returned to 20℃, the test should meet the following requirements.
Capacity change rate (△C ≤±15% of initial value
Loss value (tg δ) ≤150% of initial specification value
Leakage current(LC) ≤Initial specification value
Voltage preconditioning is required before the test: apply a rated voltage to both ends of the capacitor through a resistor of about 1000Ω and keep it for 1 hour. After pretreatment, the resistor of about 1Ω/V is discharged. After the discharge is complete, place it at room temperature for 24 hours before starting the test.

Snap-in Capacitors: Compact and Reliable Solutions for Electrical Systems

Snap-in capacitors are indispensable components in modern electrical systems, offering compact size, high capacitance, and reliability. In this article, we'll delve into the features, applications, and benefits of snap-in capacitors.

Features

Snap-in capacitors, also known as snap-mount capacitors, are designed with specialized terminals that allow for quick and secure installation onto circuit boards or mounting surfaces. These capacitors typically have cylindrical or rectangular shapes, with terminals featuring metal snaps that securely lock into place upon insertion.

One of the key features of snap-in capacitors is their high capacitance values, ranging from microfarads to farads. This high capacitance makes them ideal for applications requiring significant charge storage, such as power supply units, inverters, motor drives, and audio amplifiers.

Additionally, snap-in capacitors are available in various voltage ratings to suit different voltage levels in electrical systems. They are designed to withstand high temperatures, vibrations, and electrical stresses, ensuring reliable performance in demanding environments.

Applications

Snap-in capacitors find widespread applications across various industries and electrical systems. They are commonly used in power supply units, where they help to smooth out voltage fluctuations and improve the stability of output voltages. In inverters and motor drives, snap-in capacitors assist in filtering and energy storage, contributing to the efficient operation of power conversion systems.

Moreover, snap-in capacitors are utilized in audio amplifiers and electronic ballasts, where they play critical roles in signal filtering and power factor correction. Their compact size and high capacitance make them ideal for space-constrained applications, allowing for efficient use of PCB (Printed Circuit Board) real estate.

Benefits

Snap-in capacitors offer several benefits that make them preferred choices in many applications. Their snap-in terminals facilitate quick and easy installation, reducing assembly time and labor costs. Additionally, their compact size and low profile enable efficient PCB layout and space-saving designs.

Furthermore, snap-in capacitors are known for their high reliability and long service life, making them suitable for use in mission-critical applications. They are designed to meet stringent quality standards and undergo rigorous testing to ensure consistent performance and durability.

Conclusion

In conclusion, snap-in capacitors are versatile components that provide compact, reliable, and efficient solutions for a wide range of electrical systems. With their high capacitance values, voltage ratings, and robust construction, they contribute to the smooth operation and performance of power supply units, inverters, motor drives, audio amplifiers, and more.

Whether in industrial automation, consumer electronics, telecommunications, or automotive applications, snap-in capacitors play vital roles in ensuring stable power delivery, signal filtering, and energy storage. Their ease of installation, compact size, and high reliability make them indispensable components in modern electrical designs.
