Resistor manufacturers are experiencing price increases in the key feedstock metal ruthenium as they enter the June 2021 quarter (April 1 through June 30, 2021). This MarketEYE article correlates the impact higher metals prices are having on mass-produced resistor components consumed in all printed circuit boards, focusing on growing pressure in a critical part of the global high-tech economy. Thick Film Chip Resistors Thick film chip resistors are the workhorse of the electronics industry. Inexpensive and ubiquitous, thick ...

5G deployment is in full swing with mid-band infrastructure installed by the end of 2021 representing nearly 6 times what it was in 2019 especially in China and the Belt-Road infrastructure. However, this doesnt mean that all of the challenges have been solved. Much of the 5G infrastructure is repurposed 4G equipment at lower frequency bands. The real transition to 5G comes from the adoption of higher frequencies which have largely been categorized into sub-6 GHz and mmWave ( 20 GHz) bands. As 5G deployment transitions to hi...

Electronic components, including resistors, often have to operate in harsh, challenging environments. Given the fluctuating natures of climates all over the globe, the task that requires components to operate in high humidity, extreme dryness and incredibly moist environments comes as no surprise. Besides moisture, heat, sulfur is also endange the resistors performance. What may come as a surprise is that thick-film SMDs, the resistor type most often used in todays designs, are actually quite resilient to this common threat, ...

One of the most common components that every professional or hobbyist circuit designer encounters is to choose trusty electrical resistors from resistor manufactures as Microhm Electronics. A resistors job is to convert electrical energy, either DC or AC, into thermal energy by having higher resistance than the typical electrical conductor used in a circuit. By doing so, they can control the current flow through or voltage drop across them, offering a handy way to manipulate such things in an electronic circuit. In fact, its ...

Resistors in current detection applications are typically used to detect overcurrent conditions or remaining battery level. And although current sense resistors have been widely adopted in the automotive and industrial sectors, the recent trend towards greater sophistication and computerisation has increased current requirements, leading to a need for high power components. This includes a demand for high accuracy resistors with superior temperature coefficient of resistance (TCR) for stable operation in extreme temperature e...

Temperature Coefficient of Resistance, or TCR, refers to how the value of a resistor will vary with changes in temperature. This temperature change can be from changes in the environment around the resistor as well the resistor heating itself as it dissipates power. Growing applications demand resistors with increasely lower TCRs. Resistor manufactures like Microhm Electronics attach great importance to the production of low TCR resistors. With a typical TCR of 50ppm and a perfect tolerance, the resistance value will shift 0....

With Dyson recently announcing its surprise move into the electric vehicle market, it is clear that the electric car boom is upon us. However, the technology behind these vehicles must continue to be refined to perfect its use in alternative applications, including commercial vehicles. Meanwhile, the passive components, including resistors are must be well-picked to suitable for these electronic commerical vehicles. A recent study revealed that short driving ranges and battery technology are two of the key factors stopping co...

There are a lot of different resistor types, all with their own applications, characteristics and construction. Microhm Electronicss resistors are broadly ultilized in automotives, green engeries, communications and more. This page lists the different resistor types which are described on the resistor guide. Fixed resistors The fixed resistor type is the most common resistor, when people talk about a resistor they most probably mean a fixed resistor. Fixed resistors have a constant resistance value. Different resistor materia...
