Varistor 14D471K parameters and applications

In order to meet the space size requirements of equipment miniaturization and meet the needs of functional upgrades, power supply, battery management and special system functions are required. More and more electronic components requiring varistor protection in highly integrated circuits are required. Resistance is becoming more and more important. The working principle of the varistor is high-impedance when there is no transient over-voltage, but its impedance will decrease continuously with the increase of surge current and voltage, and its current-voltage characteristics are strongly nonlinear.

So what about the 14D471K varistor? 14 refers to the chip diameter of 14MM, D refers to the chip shape is circular, 471 refers to the voltage is 470V, K refers to the error is plus or minus 10%, and the parameter is not visible The capacitance is 430pF and the current is 4500A/6000A, but different series from different manufacturers are different.

The 14D471K has these features:

1. Wide operating voltage (V1mA) range: from 18V to 1800V;

2. Rapid response to transient overvoltages;

3. Powerful ability to absorb transients.

Mainly used in:

1. Transistor, diode, integrated circuit, thyristor or triac semiconductor protection;

2. Surge protection in consumer electronics;

3. Surge protection in the electronics industry;

4. Surge protection in household appliances and petroleum products;

5. Surge absorption of relays and solenoid valves.
