Introduction to Parameters and Models of 1206 3R 1W Surge resistant High power Resistance Analysis of the technical advantages and applications of Ellon EAM16FT3R00DES 1206 3R 1W 1% 50PPM anti sulfide metal film patch resistor.

The working principle of current sensing resistor and its application in circuits Hnstshop Mall explains the working principle of current sensing resistors and the application of current sensing resistors in a generous manner.The recommended brand is:ELLON. Current sensing resistor is a special type of resistor used to measure the current in a circuit. Its working principle is based on Ohm's law, that is, current is equal to voltage divided by resistance. By connecting a current sensing resistor in a circuit, we can indirectly measure the magnitude of the current by measuring the voltage passing through it.

Material and Characteristics Description of Precision Resistors The so-called precision resistor mainly refers to a resistor with high precision in resistance value and low temperature coefficient, which has high long-term reliability and is widely used in measuring equipment. Therefore, the materials required for producing such high-precision resistors are also very special and the production process is strict. The following will explain the commonly used materials for precision resistors: metal film, metal wire, metal thin, etc.

What is an anti sulfurization resistor? What are the product features? It is recommended to use the Ellon EAM series of metal film anti sulfurization resistors from the Ellon brand for high-power anti sulfurization resistors. Anti sulfide resistor, as the name suggests, refers to a resistor that has the ability to resist sulfide corrosion. In industrial production environments, especially those with high temperature and humidity and containing sulfide gases, ordinary resistors are easily corroded by sulfides, causing changes in resistance values and ultimately affecting the service life and performance of the entire electronic product. And the anti sulfurization resistor, through special materials and process design, can maintain a stable resistance value in such harsh environments, ensuring the normal operation of the circuit.

High precision resistors and precision resistors: differences and applications There are still many differences between high-precision resistors and precision resistors. There are mainly the following points: 1. Differences in accuracy. 2. Differences between temperature drifts. 3. Differences in long-term stability. Differences in production processes, etc.

Its resistance value is 0.0002R (0.2mR),

Introduction to Precision Resistor Selection (Example of Work) The main core parameters of precision resistors include volume, resistance, accuracy, power, temperature drift, voltage, and temperature, which are key parameters. Each parameter will have certain changes in different environments, so even the resistance of the same parameter will have different changes in different applications. We can provide examples of precision resistors below.

Application scenarios and importance of anti sulfurization resistors Especially the Ellon brand's Yineng EAM series metal film anti sulfurization resistors. The core characteristic of sulfide resistance is its ability to effectively resist the erosion of sulfides. This characteristic makes it perform well in environments that are easily exposed to sulfur-containing substances. Firstly, in industrial control systems, sulfide gases are present in the production environment of many factories, such as chemical plants, refineries, etc.

What core components are used in the EHOM brand EP1650-3 outdoor power supply? The EHOM brand EP1650-3 outdoor power supply has a built-in 1024Wh lithium iron phosphate battery, and the measured weight of the whole machine is about 13.7kg. The rated output power of the power supply is 1650W, with a peak output power of 2700W. It is a pure sine wave output and has three new national standard output interfaces. This outdoor power supply uses a large number of well-known brand electronic components, such as Zhirong's protocol chip SW3516P, Zhaoyi's innovative GD32F303RCT6, Renesas ISL81601, Yineng's ESR bare copper shunt resistor, Zhongying's SH367309, Beiling memory model BL24C256 and voltage regulator chip BL1084, etc.
