The medical industry typically requires components of high performance, high accuracy and reliability, such as precision resistors and capacitors. There are a number of imaging products available here, including displays and multimedia embedded products. Wireless communication for low-power devices and mobile medical devices is also becoming increasingly popular. In general, trends in the medical electronics arena include further miniaturization, portability, wireless capabilities, customization and personalization.

Medical electronic products are one of the most important applications of precision resistors. The main reason is that medical electronics are very demanding on electronic components in circuits, especially for resistors that regulate current and voltage. In addition, the responsibility of the medical industry makes the performance of the product even more sloppy.

In general, precision resistors used in medical devices are mainly including
alloy resistance, thin film precision resistors, metal film resistors, wirewound resistors, etc.
They have the following characteristics
 
1. Alloy resistance
Low resistance, high precision, low temperature coefficient, withstand current, high power, current sampling and short circuit protection.
2. Metal film resistance
Low noise, high temperature resistance, high precision, stable performance, simple and lightweight structure
3. Thin film precision resistor
Advanced film technology, very accurate accuracy of 0.5%, ultra-low temperature coefficient, the lowest temperature drift can be 10ppm,
It is the first choice for precision instruments.
4. Wirewound resistor
The resistance value is extremely high, the noise is small, stable and reliable during operation, the temperature coefficient is small, and it can withstand high temperature.
   
The portable medical device represented by electronic blood glucose meter and electronic sphygmomanometer can provide long-term follow-up treatment and real-time data analysis for patients, which not only eliminates the inconvenience of patients going to the hospital, but also relieves the pressure of medical institutions. The device still has the problems of single function and insufficient detection stability, and needs continuous improvement, and the precision resistor is also an important part.
