Medical Circuit Protection

Arrow Electronics Medical is Arrows answer to the unique challenges presented by the medical market. It provides access toa vast range o leading medical application technologies. Arrow o ers comprehensive support rom concept to production andbeyond, and delivers the value you seek in a ull-service engineering and supply chain partner.

With todays technology, portable, handheld medical devicesare improving patient care both at home and in medical

acilities. The ability o these devices to communicatecontinuous in ormation to caregivers almost anywhere holdsthe promise o improved care at lower cost. However, theirdemand or reliability and sa ety requires the proper use oelectronic circuit protective devices.

Arrow equipment designers pay close attention to reliabilityand sa ety issues in circuit designs and component selection.In act, a key design element involves using overvoltage andovercurrent protection components, which help preventcircuit damage due to electrostatic discharge (ESD), overloadcurrents, and other surges.

These threats are all ghosts in a circuit that can rendera device useless. Arrow o ers medical electrical devicemanu acturers complete solutions and the latest technologiesin small packages to meet the stringent sa ety requirements oEN 60601-1-2, Electromagnetic Compatibility. Dont wait untilthe last phase o the design process to combat the inevitabletests to come; discuss compatibility issues early in FMEAs,and ask your representative how Arrow can aid to mitigatethese culprits in your medical devices.
