Hello, Welcome to Dasenic

The 7408 integrated circuit is a classic TTL (transistor-transistor logic) type IC, which is widely used in various digital circuits. It contains four 2-input AND gates, each with two inputs and one output, for performing logical AND operations.

hFE, also known as current gain or β (Beta), is an important parameter of the transistor, which represents the ratio between the base current and the collector current. It describes the gain capability of a transistor when amplifying current.

Both IGBTs and MOSFETs are important semiconductor devices that are widely used in power electronics, switching power supplies, and other high-power control systems. They can both be used to control the flow of current, but their operating principles, characteristics, and application scenarios differ.

WiFi 7 (802.11be) and WiFi 6 (802.11ax) are both wireless network communications standards, but they have significant differences in performance, spectral efficiency, latency, and the number of devices they support.

The choice of PCB surface finish is more than just a detail; it determines the performance and lifespan of the PCB. The versatile and robust Electroless Nickel Electroless Palladium Immersion Gold (ENEPIG) and the reliable and classic Electroless Nickel Immersion Gold (ENIG).

Epson FA-238A is a high-performance quartz crystal oscillator widely used in automotive, industrial and consumer electronics fields. It is particularly suitable for automotive-grade and high-reliability applications, with excellent temperature stability, low power consumption and high precision.

Tantalum capacitors are often used in high-precision circuits due to their high reliability, stability and small size, but due to their high price and polarity requirements, special attention should be paid to the connection polarity during design.

Clamping diodes are a common electronic component, also known as protection diodes or baropendulum diodes.

There are many topologies that can be used to power LEDs. As you probably already know, you need to first identify your design requirements before you start selecting, or you may end up with a design that is less than ideal or, worse, not guaranteed to work properly over the long term.

As global supply chain pressure increases, more and more electronic component companies are establishing production bases in places such as India and Southeast Asia, promoting the regionalization of supply chains.
