Popular knowledge of chip varistors


One type of varistor is a chip varistor, which is the same as a zinc oxide varistor. The core of the varistor is zinc oxide.

The element of the non-linear resistor is made into an electric shock protector device, and the main material of the zinc oxide varistor is oxidized by the name

Zinc is the main material, while adding some other trace elements, and then using our ceramic process to make a half of a mixture

Conductor components, zinc oxide varistor has a basic characteristic, which is the use of nonlinear characteristics of the relationship between voltage and current, such as

When the varistor voltage is lower than the voltage across the varistor, the resistance of the varistor will be large, generally in the order of several megaohms.

If the voltage at both ends continues to rise above the varistor voltage of our varistor, the resistance of the varistor will vary with the varistor

The rise of the pressure will be extremely high, and it can be reduced to a small ohm level, generally only milliohms, so the varistor and us

Ordinary resistors are different. Ordinary resistors are subject to our Ohm's law, but chip varistors because

The varistor voltage is a nonlinear special relationship between voltage and current, so the chip varistor does not necessarily have to comply with Ohm's law.

If our nominal rated voltage is greater than the voltage across the chip varistor, the resistance of our chip varistor will be very high.

Large, can be close to infinity, which means that there is almost no current flowing inside the line at this time, if the chip varistor

When the voltage is higher than the nominal rated voltage, our varistor will be quickly broken down and the fuse will be disconnected.

The high-resistance state is converted to a low-resistance state, at which time the operating current is also greatly increased, and then if the voltage across the varistor is low

At the nominal rated voltage, our chip varistors return to their previous state (high-impedance state).

The process of making a chip varistor is also very simple, mainly requires lamination, cutting, debinding, sintering, chamfering, terminal electrodes,

In the electroplating process, the chip varistor can be fabricated http://.
