Introduction
The online version of "The Potentiometer Handbook" is based on the original publication by McGraw-Hill. Minimal updates have been made, primarily in the areas of Industry Standards and Military Specifications. The technology discussed remains relevant and unchanged over the years.

Navigation and Usage
Users can navigate the document by scrolling or using the Table of Contents to jump to specific sections. The document requires Acrobat Reader 8 or higher for optimal functionality. Additional resources and application information can be accessed through the Bourns website.

Industry Standards
The Variable Resistance Components Institute (VRCI), now known as the Variable Electronic Components Institute (VECI), provides standards for various types of potentiometers, including precision, trimming, industrial grade, and surface mount types. Links to these standards are provided for user convenience.

Military Specifications
Military specifications for potentiometers are widely used by both military and non-military users as standard references. These specifications are periodically updated and can be accessed through the Defence Supply Center Columbus (DSCC) website. Key specifications include Mil-PRF-12934 for wirewound precision and Mil-PRF-39023 for non-wirewound precision, among others.

Standards and Handbooks
Relevant standards such as Mil-STD-202 for test methods and Mil-STD-790 for reliability assurance are available. The Mil-HDBK-199 handbook provides guidance on the selection and use of resistors.
