Shenzhen Sunway Communication Co., Ltd. was established on April 27, 2006 and is one of the first national high-tech enterprises. On November 5, 2010, the company was listed on the ChiNext board of the Shenzhen Stock Exchange with the stock code 300136.SZ. Relying on the world's leading RF device R&D, design, and manufacturing solution provider, we provide customers with comprehensive standard passive component solutions - resistors, capacitors, and inductors. The product applications involve consumer electronics (smartphones, personal computers, smart wearables, etc.), automobiles, Internet of Things/smart homes, communication, data centers, and other fields. It is a new generation of information industry technology supported and encouraged by the state.
Murata Co., Ltd. has expanded its series of PTC thermistors with a size of 0603M (0.6 × 0.3 × 0.3mm) for overheating detection, specifically designed for mobile devices and vehicles. It has also added products with a nominal resistance of 1k Ω and sensing temperatures of 105 ℃ and 115 ℃. This product is scheduled to start mass production from October.
What is the reason why a discharge resistor must be set for MOS switch applications?
Murata Manufacturing Co., Ltd. has developed a 0603M size (0.6 × 0.3 × 0.3mm) copper electrode negative temperature coefficient (NTC) thermistor, with models "NCU03XH103F6SRL" and "NCU03XH103F60RL". This new product expands the size lineup of the NCU series and meets the high-density and miniaturized requirements of circuit boards in the automotive market, as well as the high reliability requirements for electronic components. Mass production has begun and samples can be provided.
With the increasing popularity of electronic equipment today, circuit protection is particularly important. Whether it is mobile phones, computers or household appliances, all kinds of components to ensure the safe and stable operation of the circuit. Its PTC thermistor, self-restoring fuse and fuse are three common circuit protection components, like the three musketeers of the guard circuit, each showing their powers to protect our electronic equipment from the threat of overcurrent.
We often encounter how to choose surface mount resistors when selecting products, because different materials have different characteristics. In addition to the differences in materials and characteristics, many factors such as delivery time and price need to be considered. Below, we will explain the advantages and disadvantages of metal foil resistors, metal film resistors, thin film resistors, and thick film resistors, so that the selection of surface mount resistors is not confused.

Wide electrode patch resistors (long electrode resistors) have the following characteristics: good stability, strong current carrying capacity, and good heat dissipation performance.
Long electrode patch resistor is a special structure of patch resistor. By using side electrodes as solder pads, the contact area between the solder pads and the PCB is increased, resulting in better heat dissipation and high current. It has excellent stability and impact resistance during use. Long electrode surface mount resistors are divided into metal foil long electrode surface mount resistors, also known as alloy resistors, and wide electrode surface mount resistors in later processes. Their main advantage is their strong impact resistance.
As an indispensable basic component in electronic circuit, the resistance value is related to the working state of the circuit. How to view and judge the resistance value of a resistor is a basic skill for electronics enthusiasts and engineers. This article will introduce several common methods to determine the size of the resistance value of a resistor.
Electrical circuit, resistance is a basic and indispensable component. It not only undertakes the important tasks of current control and voltage distribution, but also plays a very important role in protecting circuits and regulating signals. This article will take you deeper into the basic role and working principle of resistance, debunking the science behind this small device.
