Automative Chip-Resistors are usually composed of a metal film and an insulating film. The metal film has tiny lines that form the resistive element of the resistor. An insulating film is used to protect the resistor from external interference and damage.
Thin Film Chip-Resistors have the characteristics of high precision, good stability, strong anti-interference, small size, good thermal stability, and low price, and are widely used in various electronic equipment, such as computers, communication equipment, televisions, audio equipment, automotive electronics, and other fields.
A surface Mount Device Resistor (SMD resistor for short) is an electronic component manufactured by surface mount technology.
High-voltage chip resistors play a very important role in circuits that withstand high voltage and high power. They are widely used and involve many fields. A high voltage chip resistor is an electronic component commonly used in high voltage applications such as power supplies, amplifiers, and measurement instruments, among others. It consists of several high voltage resistor pieces that can withstand higher voltages and can be connected together to provide the desired resistance value.
TVS (Transient Voltage Suppressors) and MOVs (Metal Oxide Varistors) are two commonly used electronic components for voltage protection in various applications. They are designed to protect electrical and electronic circuits from overvoltage and surge events that can cause damage or failure.TVS devices are solid-state components that exhibit a highly nonlinear resistance to voltage spikes, making them effective for suppressing high-energy transients. They are made from semiconductor materials such as silicon, which can handle large surge currents and have a fast response time. TVS devices are widely used in applications such as power supplies, motor control, telecommunications, and automotive systems.MOVs are ceramic-based components that offer a similar function to TVS devices but have a different structure and operating principle. They consist of a metal oxide material sandwiched between two electrodes, which form a non-linear resistor. When the voltage exceeds the threshold level, the MOV conducts and dissipates the excess energy. MOVs are commonly used in surge protection applications for AC power lines, data lines, and telecommunication systems.Both TVS and MOVs provide protection against voltage transients and surge events, but they have different performance characteristics and are suitable for different applications. TVS devices are ideal for high-speed circuits and applications that require fast response time, while MOVs are better suited for high-energy transients and applications with low-frequency voltage transients.
Customers interested in TVS and MOVs products should consider factors such as the voltage rating, surge current rating, clamping voltage, response time, and reliability. They should also compare the products' material composition, cost, and performance characteristics to select the best solution for their specific application. Compared to other similar products, TVS and MOVs offer high reliability, excellent performance, and a cost-effective solution for voltage protection in various applications.
