Resistor's role in measuring and correcting LED bin

Resistor's role in measuring and correcting LED bin

LED boards are different from traditional circuit boards, often being larger and especially longer and hence calling for revised board transport and indexing systems for screen printing and pick-and-place processes. Vacuum picking is complicated due to the wide variance in lens curvature between LED parts of different product families and different manufacturers. Microhm Electronics resistors play an important role in measuring and correcting LED bin. Managing LED BIN codes By homogeneous placement, manufactures populate any ...

Single through-hole resistors' characteristics and installation

Single through-hole resistors' characteristics and installation

Wirewound and axial packages are the two types of through-hole resistors, with axial packaging representing the most commonly used. This resistor size is based on its power rating. The axial leads are at each end of the cylinder or box-shaped component. They are used for short distances and they have a low or flat profile on the board. Wirewound resistors are usually more expensive, higher-end components used based on their higher power rating or inherent maximum temperature range. Wirewound resistors and axial resistors are ...

Why shunt resistors for current sense applications?

Why shunt resistors for current sense applications?

Today, almost all the control and monitoring circuit uses shunt-based current measurements to replace sensors. To make these measurements accurately, it is useful to understand how shunts work. Microhm Electronics shunt resistors are widely ultilized in precison current sense applications. A shunt is a low-value resistor used to measure current it is therefore also referred to as a current-sense resistor. The shunt typically connects in series so it carries the current of interest. A voltage measurement device then connects i...

More anti-sulfur resistors used  in harsh environments

More anti-sulfur resistors used in harsh environments

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, ...
