Portable Ultrasound Scanners

Portable ultrasound scanners make diagnostic imaging available in emergency, home care, and hospital settings. This block diagram highlights Littelfuse components that help scanners operate safely while producing accurate images. Our solutions include MOSFETs that serve as high-voltage pulse generators, C&K tactile switches for operator controls, and several types of ESD protection.
