NPO is a high-frequency material for chip ceramic capacitors, with a working temperature of - 55+125 degrees Celsius and high temperature resistance. The capacitance temperature characteristic is+/- 3

When selecting TVS, the following main factors should be considered: (1) If the TVS is likely to withstand spikes (surge voltages) from both directions, it should be bipolar, otherwise it can be unipo

According to polarity, it can be divided into two types: unipolar and bipolar; According to the purpose, it can be divided into general type and special type; According to packaging and internal struc

Folded electrical characteristic 1. The V-I characteristic of unidirectional TVS is the same as that of ordinary zener diodes. The reverse breakdown inflection point is approximately "right angle", wh

Operating principle of TVS device Transient (transient) voltage suppression diodes, referred to as TVS devices, under specified reverse application conditions, when subjected to a high energy transien

The working principle of TVS diodes is similar to that of common zener diodes. If the breakdown voltage on the label is higher, the TVS diode will conduct. Compared to zener diodes, TVS diodes have a

The SMD transistor and the plug-in transistor are the same, except that the packaging is different. The patch is smaller, saves space and eliminates manual plug-ins. SMD transistor SMD transistor Plug

According to polarity, there are two types: one is NPN type triode, which is the most commonly used type, and the other is PNP type triode. There are two types of materials: one is silicon triode, the

In addition to being used as an AC signal amplifier, a triode can also be used as a switch. Strictly speaking, the action of a triode is not exactly the same as that of a conventional mechanical conta

An important parameter of a triode is the current amplification coefficient β。 When a small current is applied to the base electrode of a triode, an injection current can be obtained at the collector

The basic function of a SMD transistor is to amplify weak electrical signals to a certain intensity. Of course, this conversion still follows the conservation of energy, and it simply converts the ene
