Welwyn / TT Electronics DPCR Defibrillator Pulse Chip Resistors

Welwyn / TT Electronics DPCR Series Defibrillator Pulse Chip Resistors are designed to withstand medical defibrillator surges. The resistors prevent electrical energy from being diverted into sensitive monitoring equipment connected to a patient. This avoids any reduction in the effectiveness of defibrillation, while also protecting the equipment. 20K and 51K values at 5% tolerance are available and the resistors can withstand ESD to 15kV. Welwyn / TT Electronics DPCR Series Defibrillator Pulse Chip Resistors applications include heart monitors, blood flow monitors, portable defibrillators, and neurological monitors.

Physical Data

Welwyn / TT Electronics DPCR Defibrillator Pulse Chip Resistors

Construction

Thick film resistor material, overglaze, and organic protection are screen printed on a 96% alumina substrate. Wrap-around terminations have an electroplated nickel barrier and solderable coating; this ensures excellent ‘leach’ resistance properties and solderability.
