The common temperature probe contains a thermocouple consisting of two dissimilar metals welded together to form an electrical junction. A voltage that varies with temperature is generated. Slightly less accurate than resistance temperature detectors (RTDs), thermocouples cover a wide temperature range and respond quickly. Combinations of different metals create different voltage responses. All dissimilar […]

Advancements create easy-to-use sensors
By Bill Schweber for Mouser Electronics Significant advances have been made in delivering high-performance, low-cost, easy-to-use sensors for a diverse range of physical phenomena, with progress often based on micro-electromechanical systems (MEMS) technology. There’s always been a widespread need for electronic sensors that can handle the diverse range of physical phenomena such as light, pressure, […]
How to select components for a digital-controlled Totem-Pole PFC
By Bill Luo (Luo Zhizheng), Sr FAE, ACEINNA Transducer Systems and Jason Zhang (Zhang Liang), AE Director, Shenzhen Advantaged Power Limited There is a lot of attention being paid to advanced power systems. Energy efficiency has become a critical capability in today’s world, due to pressures from every sector of the market. To achieve substantial […]
Rudiments of radiated EMI/EMC
Radiated emissions standards are generally more focused on higher-frequency noise sources. At about 30MHz, there is a transition between concern with conducted and radiated emissions. Above that frequency, conducted emissions are not usually a major problem. And below 30MHz, the various interconnects and conductors in most electronic systems are not effective antennas for emitting radiated […]
Lasers and how to measure their output
Laser is an acronym for light amplification by stimulated emission of radiation. Lasers, of course, started out as comprised of discrete components. The most basic laser consists of a cylinder containing the lasing medium, a material that emits light when exposed to an outside source of energy. The gain medium can be gas, liquid, solid […]
How to achieve mass market fixed wireless access with fiber-like speeds
by Kevin Tang, Sr. Director, Strategic Business Development, ON Semiconductor Market demand for higher bandwidth broadband services is on the rise, thanks to the rapid growth of the internet, social media, and online streaming services, especially as the number of broadband users per household increases and the trend of cord-cutting continues to accelerate. Across urban, […]

5G Technology World interviews Qualcomm’s Danny Tseng on what to expect from 3GPP Release 17.
Conducted and coupled EMI/EMC concepts
In addition to the International Telecommunications Union (discussed in part 1 of this FAQ series), there are several organizations that define and regulate acceptable levels of conducted and radiated emissions from electronic devices. These various agencies have developed numerous standards generally based on the operational environment of the specific device. Effectively managing EMI is a […]
How to optimize building and home automation designs to be more energy-efficient
By Brian Dempsey, system design engineer, Texas Instruments The numbers are a wake-up call: According to the United Nations, the buildings and construction sector accounted for 36% of the world’s energy consumption in 2018, contributing to a worrisome carbon footprint. And those percentages continue to grow. As a result, the race is on. Industrial design […]
