fuel level gauge shunt resistor
Resistance is one of the most used basic components in automotive circuits. The quality of resistance has a great impact on the stability of the circuit. Automobile resistance its main purpose is to stabilize and regulate the current and voltage in the circuit, and it is also used as a shunt, voltage divider and load.
The element in the circuit that blocks the flow of current is called a resistor (resistor for short). There are many kinds of resistors, usually fixed resistance and variable resistance. Resistance, sensitive resistance, drain resistance, etc.What is the working principle of automobile resistance? The braking unit in the braking resistance is made of stainless steel. The material is divided into and, which is also the main factor affecting the market price. The brake resistance element is welded between the elements. It has the advantages of corrosion resistance, no contact resistance and simple maintenance. The braking resistor is applicable to the circuit of AC 50Hz voltage to and DC voltage to, and is mainly used for starting, braking and speed regulation of the motor in the inverter cabinet.
What is the working principle of automobile resistance:
The imported brake resistors are different from the domestic ones in appearance. The imported ones are relatively small and delicate. The materials are also different from the domestic ones, but the prices are very expensive. They can be 6-8 times as expensive as the domestic ones. Although it is not as refined as imported ones, it is now the mainstream of matching frequency converters. Its advantages are low price, convenient after-sales service, timely supply and better corrosion resistance than imported ones.
What is a car resistor like:
SMD low resistance braking resistance products can be divided into two categories according to their materials and structures. One type is products based on the general thick film patch brake resistance technology called thick film low resistance, and the other type is metal low resistance products using metal materials. These products are used differently according to the required performance. Generally, they are thick film low resistance resistance products with tens of M Ω ~ and metal low resistance products with a few m Ω. The characteristic of metal low resistance resistance resistance is to ensure higher rated power. The general shape of the electrode formed on the short side of the patch and the long side electrode type of the electrode formed on the long side of the patch. In general, the PCB board of long side electrode type products has better bonding reliability and temperature cycle characteristics after installation. Moreover, compared with the short side electrode type products, it also has the characteristics of better heat dissipation to the mounting plate and higher guaranteed rated power.
