Keywords: PTC , NTC, lithium battery Among many lithium ion protection schemes, multi-level protection schemes have been widely adopted to obtain high safety of lithium ion batteries. Usually multi-level protection includes active and passiv....
1.1 Model design (1) Parameter calculation: The central operating frequency fc of the system is 915 MHz, and the calculation formula of the central working wavelength c is: The characteristics of the helical antenna are determined by D . In....
In many power equipments, due to the installation process and aging, etc., the contact resistance of the power line contacts becomes large, which in turn causes the temperature to rise, and in severe cases, the contacts are blown, causing po....
To ensure proper operation of power semiconductor components, logic components, microcontrollers, and processors, overheating must be avoided. With its compact size (such as the EIA0402), the new SMD NTC thermistors can be placed directly ad....
In LED lighting systems, SMD NTC thermistors can help achieve higher luminous efficiency and extend the life of LEDs. The efficiency of the LED source is highly dependent on the temperature of the semiconductor junction. Because of the extre....
Advanced charging technology not only requires the battery to have the highest possible temperature, but also ensures that the charging current at the highest allowable temperature is lower than the maximum charging current of the battery. W....
D-53 is the NTC thermistor temperature sensor (temperature sensor) 25 degrees resistance 5K temperature control range 0-150 degrees NTC thermistor temperature sensor temperature control range 0-150 degrees circuit diagram....
See the simple DC bridge circuit shown in the figure for precision measurements using thermistor manufacturers. The correct choice of resistors R2 and R3 will eliminate the average DC value of V. Simple DC bridge circuit diagram....
Figure 1 Measurement interface circuit Figure 1 shows the interface circuit of the thermistor sensor using the in-phase amplifier circuit for temperature measurement. The interface circuit uses a resistor to linearize the thermistor sensor,....
Choosing the right temperature sensor not only saves money, but also maximizes system performance. In this blog post, I will mainly talk about thermistors and analog temperature sensors, both of which are cost effective temperature sensing s....
