Bourns Adds Three New Application Notes to its Extensive Technical Library

RIVERSIDE, Calif., July 24, 2013 – Bourns, Inc., a leading manufacturer and supplier of electronic components, today announced that it has added three new application notes to its extensive technical library. Bourns continually develops new technical resources to help engineers solve design issues and select proven application solutions. The new documents offer development options to maximize LED streetlight reliability, provide an optimal circuit protection design for PoE-based systems and demonstrate the advantages of using non-contacting rotary sensors that help achieve higher reliability in material handling equipment.

Bourns’ new application note, “Overcoming Reliability Challenges in LED Streetlight Applications”, shows how to address the many reliability challenges, provides a viable solution to open LED failure and presents effective circuit protection options that help increase the application lifespan for LED streetlights in electrically-exposed environments.

A new application note,Enhancing the Operational Reliability of Material Handling Equipment”, provides valuable design information that allows developers to upgrade and extend the life of material handling equipment such as forklifts, pallet jacks, scissor lifts and other types of robotic machinery. The note highlights the use of non-contacting rotary sensors as a viable technology solution to overcome many of the design limitations of contacting technology components and optical encoders.

Presenting a robust lightning protection circuit solution for PoE-based applications, Bourns’ third new application note is entitled, “Lightning Surge and AC Power Cross Protection for PoE Applications.” This valuable design resource highlights a new solution where the protection circuit is capable of withstanding severe lightning surges such as 4 kV 10/700 μs voltage surges per ITU-T K.44. It also explains how to implement effective AC power cross protection and demonstrates how this solution has minimal impact on signal integrity in low voltage, high-speed communication circuits.
