FAQS about Selection of capacitors for hospitals

What types of capacitors are used in non-critical medical applications?

Capacitors that are designed for use in portable and wearable devices such as electro cardiograms, ultrasonic echo devices, and blood gas analyzers are also in this category. Compared to capacitors for implantable medical devices, components for use in non-critical medical applications have less stringent reliability requirements.

Why are capacitors used in implantable medical devices?

Capacitors for use in implantable medical devices are required to have high reliability, large capacity and be small in size. As compared to capacitors for use in portable and wearable medical devices, these components are subjected to a more stringent screening process.

How reliable are capacitors for life-supporting and non-life- supporting medical devices?

Capacitors for use in life-supporting and non-life-supporting medical devices are required to have high reliability, and they are taken through stringent screening checks. Moreover, unlike capacitors for use in consumer electronics, these components have special evaluation criteria and service life requirements.

What is a capacitor used for?

Capacitors are employed for use in implantable medical devices such as defibrillators, insulin pumps and pacemakers, as well as in portable and wearable devices (including electrocardiograms, ultrasonic echo devices and blood gas analyzers). They are required to have high reliability, offer long service life and pass stringent screening checks.

What is the difference between commercial-grade capacitors and non-critical capacitors?

Compared to capacitors for implantable medical devices, components for use in non-critical medical applications have less stringent reliability requirements. However, unlike commercial-grade capacitors, components for use in this class of medical applications are required to have higher reliability and larger capacity.

Are tantalum and multilayer ceramic capacitors suitable for medical applications?

These regulations, as well as the demands placed on electronic medical devices, have ramifications for the component selection process. In this article we will explore those impacts given that tantalum capacitors and multilayer ceramic capacitors (MLCCs) are the most popular types of capacitors for medical applications.
