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...

In terms of material used, fixed resistors are classified as chip resistors, metal film resistors, metal oxide film resistor, carbon film resistors, wire wound resistor and network resistor. Chip resistors, the most standard resistors at present, are a surface mounted type resistor which comprise electrodes suitable for PCB surface mounting. About 85%~90% of fixed resistors are square-shaped resistors. Metal film resistors comprise a stable ceramic substrate coated with metal, Ni-Cr for instance. Metal film resistors outstrip...

Classifying the broad range of resistors facilitate the location and choice of them. We can assort resistors in terms of functions as well as materials, shapes and integration levels. On the basis of function, resistors are divided to fixed resistors and variable resistors. Microhm mainly manufactures fixed resistors which is the most widely used type for electronics circuits to set the conditions for a circuit. The resistance values of fixed resistor are determined during the design phase and cannot be changed afterwards. M...

Microhms high precision MVR series resistors have been offered 3 size lineup, 2321, 3825, 4618 with 4 terminals. Recently we release a new surface mount package for 2321, which is referred to as MVR2321-4C. It holds the same power, resistance range, TCR as the in-line MVR2321-4D. MVR2321-4C features wide resistance ranging from 0.001 Ohm to 50 Ohms, power covering 3W in free air at 70℃ to 40W with heat sink. TCR can be as low as 10ppm, and tolerance down to 0.1%. Apart from these merits , very low inductance and 0.1% load s...

According to Ohms law, V=R・I, the values of any two of the voltage, current, and resistance of resistor are known, it is possible to determine the value of the remaining parameter. Not only lamps but also heaters, motors require energy to operate. The amount of energy required is named power consumption which is P(W)=V(V)*I(A) A voltage of about 2V is applied across its two terminals can light up a LED, so one single dry cell of about 1.5V is not enough. When two dry cells are connected in series, the 3V voltage will exceed...

Resistors play a important part in electronic circuits, such as limit / manage the current, provides appropriate bias voltage to the active devices, works as load, provides bias stabilization in combination with capacitors and provides feedback. An electronic circuit and an electrical circuit has the same definition, but electronic circuits tend to be low voltage circuits. An electronic circuit is a complete course of conductors through which current can travel. Circuits provide a path for current to flow. Resistors is appli...

The most common resistors have a fixed value of resistance so are often called fixed resistors. Resistors are components used to resist the flow of electric current and have a stated value. They are shown on circuit schematic diagrams using one of the symbols shown in below. Various types of fixed resistors used to reduce voltages and currents around a circuit to help active components, transistors and integrated circuits for example, can carry out tasks such as producing or amplifying signals within the circuit. Resistors ar...

Shunts feature the characteristics of small size, offset free, very low noise, excellent linearity, high long-term stability, low TCR and high precision. Current measurement principle of shunts is also Ohms law, i.e I=V/R. Temperature, long-term stability, inductance and thermal EMF are the main influences of changing resistors resistance and voltage. Microhms precision shunt resistors minimize the effects of external factors on themselves. Microhm shunts cover a full range of size from 0805,1206 to 8420, 8518, which stamped ...

Resistors are often defined as precision or power. Engineer choose the right models to fix their applications and achieve design and practical success. Power resistors have the characteristics of tight tolerance and high stability. While their designs emphasis more on the power dissipation. Meanwhile, these resistors generally have extended operating temperature limits. Microhms newly and popular power resistors include NLR series and traditional metal clad resistors NUAL series. When tight resistance tolerance and stability ...
