High-precision Mn-Cu resistance alloy narrow ribbon is the core resistance material of various electrical instrument shunt elements. Manganese copper resistance can be used in all kinds of instrument relay, automobile relay, meter relay and so on. In the traditional process of resistance element, Mn-Cu flat strip resistance element is made up of large size Mn-Cu sheet (or strip) after punching forming and copper guide plate is made up of overlap welding. The resistance element of mn-Cu flat strip is composed of large-size Mn-...

In the existing technology, resistance testing instruments are widely used in laboratory testing or production line sampling. The connection end of the resistance tester connects the two terminals of the resistance. The resistance tester displays the resistance value. Manual single measurement can not achieve continuous measurement and mass resistance measurement. The efficiency is low. A continuous automatic resistance testing device fix the two ends of the resistance into a strip resistance belt, place it on the transmissio...

Precision resistor is a kind of very important resistor. Its precision, stability and low temperature drift design bring this resistance a superior market competitiveness. The accuracy of precision resistance represents the accuracy of resistance value. In fact, the accuracy is affected by many factors, such as ambient temperature changes, , self-heating due to self-energizing, pressure or tension from the PCB, external moisture, even corrosive gases, or welding, pulse, overload, static electricity, radiation and so on. Thes...

The precision chip resistor adopts the manganese-copper strip as the raw material. It is relatively complex to manufacture the resistor of the package size 2512 within 1% tolerance. First of all, the manganese-copper strip is stamped into the required resistance pattern by precision stamping. The target resistance value is set, correcting the center value according to the upper and lower limits of the target resistance value so as to ensure that all products are controlled within the upper limit of the specification. To modif...

There are many kinds of resistors in our life, each kind of resistor has its own characteristics and technical advantages. Common ones are high-power resistance, chip resistance, plug-in resistance, precision resistance, brake resistance and so on. In charger products, wire wound resistor use the most. So why do chargers use wire wound resistor, what are the advantages of them? The common wire wound resistor, made of a resistance alloy wire, is generally made of a nickel-chromium wire or a manganese copper wire. Apart from t...

The film-type power resistance and the wire-wound power resistance are both important components of the power resistance. Usually, the film-type power resistance adopts the high-temperature vacuum coating technology to tightly attach the resistance material to the surface of the ceramic rod to form a protective film, and then add the appropriate joint to cut. And the surface is coated with epoxy resin seal protection. Its surface is often coated with green protective paint. The thickness of the film power resistance determine...
