TETM7-10 electrical components are specifically designed to suppress high-frequency noise and spike interference on signal lines and power lines, and also have the ability to absorb electrostatic pulses. Ferrite beads are used to absorb ultra-high-frequency signals. Some RF circuits, PLL, oscillator circuits, and circuits containing ultra-high-frequency memory (DDR SDRAM, RAMBUS, etc.) all require ferrite beads at the power input. Inductors are energy-storage components used in LC oscillator circuits, medium- and low-frequency filter circuits, etc., with an application frequency range rarely exceeding 50MHZ. Ferrite beads have high resistivity and permeability, equivalent to a resistor and inductor in series, but both resistance and inductance vary with frequency.

TETM7-10 electrical component principles

A resistor consists of three parts: the resistive element, the substrate, and the leads (for solid-core resistors, the resistive element and substrate are combined into one), and only the resistive element determines the resistance value. The volt-ampere characteristic is represented by a graphical curve showing the relationship between voltage and current at the resistor terminals. When voltage and current are proportional (the characteristic is a straight line), it is called a linear resistor; otherwise, it is called a non-linear resistor. The maximum power dissipation allowed for continuous operation of the resistor at the rated temperature (maximum ambient temperature) tR. For each type of resistor, a maximum operating voltage is also specified; that is, when the resistance value is high, the maximum operating voltage must not be exceeded even if the rated power has not been reached. The rated power of a resistor refers to the maximum power allowed to be consumed during long-term continuous operation in DC or AC circuits. Load characteristics: When the ambient working temperature is lower than tR, the resistor must not exceed its rated power; when it exceeds tR, the load power must be reduced. Each type of resistor has specified load characteristics. In addition, the allowable load is correspondingly reduced under low air pressure. Under pulse load, the average pulse power is far lower than the rated power, and separate specifications generally apply.

TETM7-10 electrical component features

Among various types of switches, there is a component with the ability to "sense" objects approaching it—the displacement sensor. Using the sensitivity of the displacement sensor to approaching objects to control the opening or closing of the switch is known as a proximity switch. When an object moves toward the proximity switch and approaches within a certain distance, the displacement sensor "senses" it, and the switch activates. This distance is usually called the "detection distance." Different proximity switches have different detection distances. Sometimes the detected object moves toward the proximity switch one by one at certain time intervals, and then leaves one by one, repeating this process continuously. Different proximity switches have different response capabilities to the detection object. This response characteristic is called the "response frequency."

TETM7-10 electrical component parameters

Rated voltage: refers to the safe voltage allowed during normal operation of the switch. If the voltage applied across the switch exceeds this value, it will cause arcing and breakdown between the two contacts. Rated current: refers to the maximum safe current allowed to pass through when the switch is closed. If this value is exceeded, the switch contacts will burn out due to excessive current. Insulation resistance: refers to the resistance value between the conductive part and the insulating part of the switch. Contact resistance: refers to the resistance value between each pair of contacts when the switch is in the open state. Dielectric strength: refers to the maximum voltage that the switch can withstand between the conductor and ground. Service life: refers to the number of operations the switch can perform under normal working conditions.
