The medical field has very high requirements for electronic equipment. Electrolytic capacitors play an irreplaceable role in meeting these requirements, such as electrocardiograph, blood pressure monitor, blood glucose meter, etc. Electrolytic capacitors are used in power management and signal processing to ensure the accuracy and stability of instrument measurement results. In laser surgery equipment and other optical instruments, it is used for power management and stable work of laser system, and in medical imaging equipment, such as X-ray machine, CT scanner and MRI equipment, stable power supply and signal processing are usually needed. Electrolytic capacitors can smooth power supply and support signal processing circuits in these devices, ensuring high-quality image output.
