Circuit Protection Selection Guide
Consult this guide to learn about circuit protection considerations and the solutions Littelfuse offers. Tables help match products with applications.
Protect defibrillators, patients, and emergency responders with ESD suppressors made by Littelfuse. This block diagram shows how our varistors, diode arrays, and other ESD protection solutions fit into the circuitry of defibrillators. We can also supply IGBTs with gate drivers to serve as rectifiers, reed switches for power selectors, and C&K tactile switches to turn defibrillators on and off.
Smart insulin pens, ultrasound scanners, and other portable medical devices require high-quality fuses, switching devices, and relays to perform optimally. Devices used for life support and lifesaving care such as ventilators and defibrillators also need superior ESD suppressors and surge protective devices to ensure patient and personnel safety. Littelfuse delivers FDA-qualified solutions.
A ventilator cannot fail. Components Littelfuse supplies to help ensure this degree of reliability appear in a block diagram. Our solutions include resettable PPTC device for overcurrent protection of batteries, NTC thermistors for overtemperature protection microcontrollers, and multilayer varistors for ESD protection of USB ports. We also offer Schottky diodes to prevent reverse polarity.
