What are the symbols of the pressure? A method of symbolic representation of a pressure sensitive resistance? Small make up for all of us to explain the basic knowledge of electronic components based on the pressure sensitive resistance symbol and its expression!
In our lives, the pressure sensitive resistance is used for lightning protection, anti surge and other products in the. Varistor symbols are for example: ZOV 5D151K model definition: ZOV is brand of varistor, 5 is varistor diameter 5mm, diameter of the letter D 271 is varistor voltage, 270V, K said precision is 10%. However, different functions of the pressure sensitive resistance, can be used to express the different letters of the pressure sensitive resistance symbols, can be divided into two categories: (1) the protection of the use of pressure sensitive resistance, (2) the circuit function with the pressure sensitive resistance. We are talking about the letter meaning of the symbol of the pressure sensitive resistance.

Name and meaning of the model of the pressure sensitive resistance:
Part: the main call
The second part: Category
The third part: use or feature
The fourth part: the meaning of the serial number letter
M sensitive resistance
Y pressure sensitive resistance
The common type is indicated by the number of the pressure sensitive resistance, some in the back of the pressure sensitive resistance number is also marked with the nominal voltage current capacity or the resistance body diameter, the nominal voltage, the voltage error and so on.
The following is the significance of various types of pressure sensitive resistance symbols:
D universal
B compensation
C for degaussing
E denoising
G over voltage protection
H arc extinguishing
K high reliability
L lightning protection
M ESD protection
N high energy type
P high frequency
S component protection
T special type
W voltage regulator
Y ring
Z combination type

As seen in the circuit diagram or in the purchase order to see the above letters of the pressure sensitive resistance symbols are applied to the following parts:
The first part of the letter "M" is used to show the main known as the sensitive resistance.
The second part uses the letter "Y" to express the sensitive resistor as the pressure sensitive resistance.
The third part uses the letter to express the characteristics of the use of the pressure sensitive resistance.
The fourth part with the number of serial number, and some in the back of the serial number is also marked with the nominal voltage, current capacity or resistance of the body diameter, voltage error, the nominal voltage, etc..
For example: MYL1-1 (lightning protection with a pressure sensitive resistor) MY31-470/3 (470V/3kA common voltage sensitive resistor) Y - pressure - sensitive electrical resistance L - lightning protection
Pressure sensitive resistance is a kind of voltage limiting protection device. By using the non-linear characteristic of the pressure sensitive resistance, when the over-voltage occurs in the voltage between the two electrodes, the voltage clamp can be clamped to a relatively fixed voltage value, so as to realize the protection of the circuit. The main parameters of the pressure sensitive resistance are: voltage, current capacity, junction capacitance, response time and so on. The pressure sensitive resistance symbol also expresses the pressure sensitive resistance symbol, the above is the introduction which the small makes up for everybody to the pressure sensitive resistance symbol, through the introduction to the small series whether to have the further understanding to the pressure sensitive resistance? Hope that the introduction of small series can give you help!
