This white paper focuses on isolated digital interfaces conforming to RS-485, which continues to be the industry’s workhorse standard for data transmission. The paper provides an overview of RS-485’s common-mode voltage range (CMVR) definition, and explains how isolating a transceiver’s signal and...

As modern factory automation (including servo motors, industrial robots, and computer numerical control [CNC] machines) trends toward higher precision, power, speed, multi-axis, and multi-direction, the requirement for accurate sensing of motor phase current has become ever more demanding. Traditionally, current sensing...

The electronics industry is used to riding waves of growth driven by the introduction of new categories of product. This happened with the PC in the 1980s, with networking gear in the 1990s and more recently with the smartphone. Now ‘wearable electronics’ has emerged as the next potential growth market, prompted...

Although nickel can be difficult to solder, wave or dip soldering just the PCB tails or cleaning the leads with Nickel Nu can greatly ease the solderability of nickel. Also, the use of through-pin Nylon holders that can withstand reflow and higher soldering temperatures aid in soldering nickel.
Unlike nickel,...

Devices that demand reductions in power consumption are increasing, such as cooling fans. If we looked at all process from fan production, usage in field, to scrapping the fan, the highest required energy comes from the power consumption during operation. In other words, reduction of the fan's power consumption is...
