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...

Resistors are available in different packages. The most popular ones at present are the rectangular surface mount resistors and axial resistor in through hole designs. The shape and size of surface mount resistors are standardized, most manufacturers use the JEDEC standards. The size of SMD resistors is indicated by a numerical code, such as 0201. This code contains the width and height of the package. So in the example of 0201 Imperial code, this indicates a length of 0.020 and a width of 0.010. This code can be given in Im...

Resistors are often connected inseriesor parallel to create more complex networks. An example of 3 resistors in parallel is shown in the picture below. The voltage across resistors in parallel is the same for each resistor. The current however, is in proportion to the resistance of each individual resistor. The equivalent resistance of several resistors in parallel is given by: The current through each resistor is given by: A designer might for example combine several resistors with standard values to reach a specific resist...

To check whether a resistor is good or not, we only need to check the resistors resistance value by using the ohmmeter of a multimeter. This is the best, easiest and most effective way . Take the ohmmeter and place its probes across the leads of the resistor and do not pay much attentio to the orientation as resistance isnt polarized. The resistance showing in the ohmmeter should be close to the rated resistance of the resistor. For example, when the resistance value of a resistors is 100Ω resistor with a tolerance rating ...

Resistors are widely used in automobiles, consumer electronics, computersand peripherals, communications, green energy, medicalinstruments, precision instruments and aerospace equipments. When used in LED circuits, an Light Emitting Diode (LED) emits light when an electric current passes through it. The simplest circuit to power an LED is a voltage source with a resistor and an LED in series. Such a resistor is often called a ballast resistor. The ballast resistor is used to limit the current through the LED and to prevent t...

Resistors can be divided in construction type as well as resistance material. The following breakdown for the type can be made: Fixed resistors Variable resistors, such as the: o Potentiometer o Rheostat o Trimpot Resistance dependent on a physical quantity: o Photo resistor(LDR) as a result of a changing light level o Thermistors(NTC andPTC) as a result of temperature change o Magneto resistor (MDR)as a result of a changing magnetic field o Varistor (VDR) as a result of a changing voltage o Strain Gauges as a result of mech...

When trying to build a current monitor for a wireless sensor network, what kind of resistors shall i choose, high precision resistor s or current sense resistors ? Lets see the difference between them. Current sense resistors are generally low-value, high-power resistors. They are intended to develop a small voltage for a given current, so they are low in value. When used in power supplies they may well carry significant current and dissipate significant power, so they tend to be high-power units. For many applications they ...

A fixed resistor is the one having a fixed, defined electrical resistance which is not adjustable. Fixed resistors are the most commonly used resistors and in general one of the most used electronic components. Fixed resistors are available in surface mount packages and axial leaded as well as more customized packages depending on their application. Axial leaded resistors used to be the most popular one, but now SMD resistor s gain more market share. The followingresistor symbolsare often used to depict resistors with a fixe...
