108HMK4 electrical components are instruments used to transform voltage. However, the purpose of a transformer's voltage transformation is to facilitate power transmission, so its capacity is large, generally calculated in kilovolt-amperes or megavolt-amperes; whereas the purpose of a voltage transformer's voltage transformation is mainly to supply power to measuring instruments and relay protection devices, to measure line voltage, power, and energy, or to protect valuable equipment, motors, and transformers in the line when a fault occurs. Therefore, the capacity of a voltage transformer is very small, generally only a few volt-amperes or tens of volt-amperes, with a maximum not exceeding one thousand volt-amperes.

Most microphones are electret condenser microphones (ECM), a technology with a history of several decades. The working principle of ECM utilizes a polymer diaphragm with permanently isolated charge. Compared to the polymer diaphragm of ECM, MEMS microphones exhibit stable performance across different temperatures and are unaffected by temperature, vibration, humidity, and time. Due to strong heat resistance, MEMS microphones can withstand high-temperature reflow soldering without any change in performance. Since the sensitivity change before and after assembly is minimal, this can even save audio debugging costs during the manufacturing process. Currently, integrated circuit processes are increasingly widely applied in the manufacture of sensors and sensor interface integrated circuits. This micro-manufacturing process offers advantages such as precision, design flexibility, miniaturization, integration with signal processing circuits, low cost, and mass production. A fundamental resonant frequency in such a low frequency range will result in highly uneven frequency response within the audible frequency range for the microphone, which is unacceptable for microphone applications. When tensile stress exists within the sensitive membrane, its resonant frequency increases, but at the cost of sensitivity. Of course, higher fundamental resonant frequencies can be achieved by adjusting the dimensions of the sensitive membrane, but this will still reduce sensitivity. Thus, piezoresistive solutions are not suitable for the manufacture of miniature microphones. A feasible solution is to adopt a capacitive approach to manufacture miniature microphones. The advantage of this method is that all materials used in integrated circuit manufacturing processes can be utilized for sensor manufacture. However, manufacturing micro-microphones using single-chip processes is quite difficult because the air dielectric between the two capacitor plates can only have a very small gap. Moreover, due to size limitations, bias voltage is difficult to satisfy in some application scenarios. Based on these issues, research on capacitive microphones has continued uninterrupted. Compared to traditional electret microphones, micro-electromechanical system microphones offer advantages such as small size, good heat resistance, good consistency, good stability, high reliability, and resistance to radio frequency interference, and can also output digital signals, facilitating intelligent development.

108HMK4 electrical component applications

Dedicated solid-state relays can feature short-circuit protection, overload protection, and overheat protection functions. When combined with hardwired logic encapsulation, they can realize intelligent modules required by users, directly for use in control systems. Solid-state relays are widely used in computer peripheral interface equipment, thermostatic systems, temperature regulation, electric furnace heating control, motor control, CNC machinery, remote control systems, and industrial automation devices; signal lights, dimming, flashers, stage lighting control systems; instruments, medical devices, copiers, automatic washing machines; automatic fire fighting, security systems, and as switching switches for power capacitors for grid power factor compensation, etc. Additionally, they are extensively used in chemical, coal mining, and other environments requiring explosion-proof, moisture-proof, and corrosion-resistant properties.

Among various switches, there is a component with the ability to "sense" objects approaching it—the displacement sensor. Utilizing the sensitivity of the displacement sensor to approaching objects achieves the purpose of controlling the switch on or off; this is a proximity switch. Only when an object moves toward the proximity switch and approaches within a certain distance does the displacement sensor "sense" it, causing the switch to actuate. This distance is typically called the "detection distance." Different proximity switches have different detection distances. Sometimes, detected objects move toward the proximity switch one by one at certain time intervals, and then leave one by one, repeating continuously. Different proximity switches have different response capabilities to detection objects. This response characteristic is called the "response frequency."
