Microhm Achieved Great Success in electronica Shanghai, 2019

Microhm Achieved Great Success in electronica Shanghai, 2019

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...

Power Resistors and Precision Resistors

Power Resistors and Precision Resistors

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 ...

Resistor Inductance' Feature and Effect

Resistor Inductance' Feature and Effect

Since resistors are made of conductive materials. We take inductance as an unwanted and parasitic effect. This effect is especially noticeable if the resistor is made out of wire formed into a coil shape. Depending on the application, resistor inductance might be easily disregarded, especially in DC circuits. However, parasitic resistor inductance can be a significant factor in high-frequency AC applications. The reason for this is that the impedance of a resistor rises with the applied voltage frequency due to the increase i...

Surface Mount Resistor's Size and Package

Surface Mount Resistor's Size and Package

The shape and size of surface mount resistors ( SMD resistors ) are standardized, most manufacturers use the JEDEC standards. Surface mount resistors are available in all kinds of packages. The mostly used ones nowadays are rectangular. Designing with surface mount resistors, a right solder pad size and land pattern should be used. The following table shows the land pattern for common surface mount packages. The table lists the dimensions for reflow soldering, for wave soldering smaller pads are used. The size of chip resisto...

Picking Right Resistor for LEDs

Picking Right Resistor for LEDs

If we want to light up an LED, a right resistor is a must. If we do a lot of electronics projects, were likely to have dozens of resistors lying around. If we are just green hand, an assortment might need to be prepared. Resistors also come rated to handle varying amounts of power. Higher rated power resistors are able to safely dissipate more heat generated. We know Ohms Law formula is V = I R , where V is the voltage, I is the current, and R is the resistance. To get the V in our formula, we need to know the voltage of our ...

Precision Resistors' Construction and TCR

Precision Resistors' Construction and TCR

Precision resistor here we mainly refer to thin film resistor. By depositing a thin film of resistive material, such as nickel-chromium on a silicon wafer, precision resistors for the hybrid are produced. Microhm uses standard semiconductor technology etching away the unwanted resistive film and leave the demanded resistor geometries on the silicon wafer. Each circuit contains resistors from one to serveral dozen, which depending on the design. Thin film resistors resistance value is determined by its structure and geometry....

Shunt Resistor in Battery Management System (BMS)

Shunt Resistor in Battery Management System (BMS)

A shunt resistor and magnetic current sensor are used to measure the voltage drop flowing through. It is said the intelligence of the battery does not lie in the cell but in the complex battery system. In todays automotive applications, above two current sensing technologies is generally used. The Shunt resistor is more accurate and less costly than the Hall Effect current-sensing solution, while the tapped holes assist in the PCB placement process, providing additional vibration immunity and the location of the fixed voltage...

Metal Clad Resistor is Increasingly Popular

Metal Clad Resistor is Increasingly Popular

Metal Clad Resistor is a popular resistor in the market. At present, the demand for it is increasing in many industries. For example, battery management systems of photovoltaic power generation and new energy vehicles demand a large number of high stability, high precision aluminum shell resistors, alloy resistors, film resistor and more. The aluminum shell resistor can be used as a good protection because it is applied to the resistor in an aluminum alloy case. The aluminum casing is used in the resistor to consume energy. I...
