commscope electrical components include circuit boards such as: ceramic circuit boards, alumina ceramic circuit boards, aluminum nitride ceramic circuit boards, wiring boards, PCB boards, aluminum substrate boards, high-frequency boards, thick copper boards, impedance boards, PCB, ultra-thin wiring boards, ultra-thin circuit boards, printed (copper etching technology) circuit boards, etc. Circuit boards miniaturize and visualize circuits, playing an important role in the mass production of fixed circuits and optimizing appliance layout. Circuit boards can be called printed wiring boards or printed circuit boards. Flexible wiring boards and flexible circuit boards are printed circuit boards with high reliability and excellent flexibility, made using polyimide or polyester film as the base material. They feature high wiring density, light weight, thin thickness, and good bendability.) and rigid-flex boards—the emergence and development of FPC and PCB gave rise to the new product known as rigid-flex boards. Therefore, rigid-flex boards are circuit boards formed by combining flexible wiring boards and rigid circuit boards through processes such as lamination, according to relevant process requirements, resulting in a board with both FPC characteristics and PCB characteristics.

commscope electrical components function

The main functions of potentiometers in circuits include several aspects: 1. Used as a voltage divider, a potentiometer is a continuously adjustable resistor. When adjusting the knob or slider of the potentiometer, the moving contact slides on the resistive element. At this time, the output terminal of the potentiometer provides an output voltage that has a certain relationship with the external voltage applied to the potentiometer and the angle or travel of the movable arm. 2. Used as a rheostat, when a potentiometer is used as a rheostat, it should be connected as a two-terminal device, so that a smoothly and continuously changing resistance value can be obtained within the travel range of the potentiometer. 5. Used as a current controller, when a potentiometer is used as a current controller, one of the selected current output terminals must be the terminal led out from the sliding contact.

commscope electrical components classification

In different application scenarios, the purpose of applying varistors varies, and the voltage/current stress acting on the varistor is not the same, so the requirements for varistors also differ. Paying attention to distinguishing these differences is very important for correct use. According to different purposes, varistors can be divided into two major categories: protection varistors and circuit function varistors. ① Protection varistors: 1, distinguish between power supply protection varistors and signal line or data line protection varistors, as they must meet different technical standard requirements. 2, according to the different continuous operating voltages applied to the varistor, varistors across power lines can be divided into AC type or DC type; the aging characteristics of varistors under these two voltage stresses are different. 9, according to the different abnormal overvoltage characteristics withstandable by varistors, varistors can be divided into three types: surge suppression type, high-power type, and high-energy type. ② Surge suppression type: refers to varistors used to suppress transient overvoltages such as lightning overvoltage and switching overvoltage. The occurrence of this transient overvoltage is random and non-periodic, and the peak current and voltage may be very high. The vast majority of varistors belong to this category. ③ High-power type: refers to varistors used to absorb continuous pulse groups that appear periodically, such as varistors connected in parallel to switching power supply converters. Here, the impulse voltage appears periodically, and the period is known. The energy value can generally be calculated. Although the voltage peak is not large, the average power is quite high due to the high frequency of occurrence. ④ High-energy type: refers to varistors used to absorb magnetic energy in large inductive coils such as generator excitation coils and lifting electromagnet coils. For such applications, the main technical indicator is energy absorption capacity. The protective function of varistors can be repeated many times in most application scenarios, but sometimes they are made into one-time protective devices like current fuses. For example, varistors with short-circuit contacts connected in parallel to the loads of certain current transformers.

commscope electrical components classification

1. Classification by relay outline dimensions: ① miniature relays, ② ultra-small miniature relays, ③ small miniature relays. 2. Classification by relay load: ① micro-power relays, ② weak-power relays, ③ medium-power relays, ④ high-power relays. 12. Classification by relay protection features: ① Sealed relays: relays where contacts and coils are sealed inside a cover by welding or other methods, isolated from the surrounding medium, with a low leakage rate. ② Enclosed relays: relays where contacts and coils are protected by being enclosed in a housing (non-sealed). ③ Open relays: relays that do not use a protective cover to protect contacts and coils. Among the above relays, electromagnetic relays and reed relays are the most commonly used in electronic fabrication.
