electronica China, lasting for three days, ringed down the curtain on Mar.22,2019 successfully. Microhm prepared elaborately and exhibited full range of resistors in the site. Customers from all over the world visited Microhm E5 - 5606, consulted resistors and experienced. Our staffs introductions of the features, applications and merits were brief and to the point. Customers not only stayed for a time in front of the reception to learn more about products, but also streamed into Microhms booth to have a close look of the mat...

LEDs are constant current devices with a predictable forward voltage drop based on the amount of current flowing through them. These current-voltage (I-V) curves are available in the datasheet for specific LEDs. If you want to drive a green LED with a forward voltage of 3V off a 5V power supply, you need something in that circuit to absorb the extra 2V. If you do not absorb that extra voltage, the LED junction will try to draw enough current to increase that voltage to 5V and burn itself up. The easiest way to absorb extra po...

After an extended period of long lead times and robust demand, suppliers of passive components such as capacitors, resistors and inductors are now bearing the brunt of a weakening electronics market that is manifesting itself in slackening sales of electronics goods and prompting suppliers to lower quarterly forecasts. As electronic product design cycles typically involve the specifying and design-in of passive, interconnect, and electromechanical components later than semiconductors, suppliers of those parts typically feel a...

The basics of electronics involve calculating the equivalent resistors in series or parallel. The designer learns the resistance of resistors in series is the sum of all the resistances, and when mounted in parallel, the inverse of the final resistor is equal to the sum of the inverse of the resistors. Micrhom Electronics provides broad range of resistors for engineers options. In the second step, designers learn that two resistors in series create a voltage divider. If one of these resistors is an NTC (Negative Temperature C...

Resistors, no matter chip ones or through-hole ones, are a fundamental component in electrical circuits. Early scientists came to understand the concept of resistance shortly after they were conducting tests to determine the results of passing electricity through all kind of materials and subsequently discovered electrical current. While copper, gold, and aluminum were found to be great conductors with low resistance, air, mica, and ceramics were considered resistors because of their ability to greatly limit the flow of elect...

Science and engineering students typically experiment with axial leaded resistors, like PMRY series, learning a color code to identify the resistor value based on the stripes around the resistor body. In practice, however, axial leaded resistors are overshadowed in board fabrication by resistors for which the construction, package styles, and materials are targeted for specific applications. Microhm Electronics offers a wide variety of resistive products that include devices that range from industry standard size chip resisto...

Microhm Electronics MMS8518 power metal strip shunt resistors employ a solid metal nickel-chrome alloy or manganese copper resistive element with large-area copper to realize resistance values down to 100 and power ratings to 36W. Compared with other manganese alloy shunts and Hall Effect current sensing solutions, MMS8518 increases accuracy and lower costs, and the two sense pins of the WSBS8518 aid in PCB mounting and provide consistent contact point locations on the shunt. Offered in the 8518 case size, shunt MMS8518 featu...

Metal film resistors are axial resistors with a thin metal film as resistive element. The thin film is deposited on usually a ceramic body. Metal film resistors have a thin metal layer as resistive element on a non-conducting body. They are amongst the most common types of axial resistors. Other film type resistors are carbon film and thick and thin film resistors. The appearance of metal film resistors is similar to carbon film resistors, but their properties for stability, accuracy and reliability are considerably better. M...

A shunt is an element that is used in a circuit to redirect current around another part. Microhm Electronics is specilized in the RD of diverse shunt resistors. The areas of application vary widely. For some applications, electrical devices other than resistors can be used. A few examples are given to illustrate the diversity of shunts. Protecting a circuit against overvoltage A method to protect a circuit from a too high voltage is using a crowbar circuit. When the voltage gets too high, a device will short circuit. This res...
