How to design guide for precision resistors

Even in this digital age, a number of measurement and instrumentation applications rely on the accuracy of the value of one or more resistors. There are essentially three types of error source to be understood:

  1. Measurement errors - which limit the precision with which the actual resistance value can be known.
  2. Short-term change factors - reflecting uncertainty in the resistance value in a customer’s recently assembled PCB.
  3. Long-term change factors - reflecting value drift throughout the product’s life.

Riedon resistors is used in critical medical systems

Each year, more than 250,000 Americans die from sudden cardiac arrest. With recent technological advances, a portable lifesaving device called the automated external defibrillator has been invented. It is an important life saving device, and has saved many . Riedon sells resistors to some of the major defibrillator manufacturers.

Resistors are a critical part of this system. A stable and repeatable measurement of the charging voltage is a critical funtion of this circuit, as this determines the amount fo electrical energy delivered to the patient.
