The patch resistor consists of four main parts.​ 1) Substrate: The substrate material is generally 96% aluminum oxide ceramic. In addition to good electrical insulation, the substrate should have good thermal conductivity at high temperatures. Electrical properties and mechanical strength. In addition, the substrate should be flat and accurate. Standard to fully guarantee resistance. Electrode …

The ideal use environment for capacitors is to use in places where the temperature and humidity are not too high, but in some cases, many capacitors will encounter a very humid environment, and may even encounter water. Is the capacitor waterproof? Most capacitors are afraid of humidity and high temperatures.​ For the vast majority of …

There are three types of common precision resistors: metal film resistors, wire wound resistors and block resistors. 1, metal film resistance is the most common, but better for precision metal film resistance, characterized by tiny temperature coefficient, resistance value is comparatively stable. ​Nevertheless, because the membrane is comparatively thin and thus relatively delicate, the helical …

1. Classification of timers The Siemens S7-200 SmartCPU has three types of on delay timer TON, hold on delay timer TONR, and off delay timer TOF. However, the total number of timer calls in STEP 7 Micro/WIN SMART is limited to 256, and the timer cannot be used when S7-200SMART subroutine is called for multiple …
