SMD Resistor, also known as Chip Fixed Resistor, is a kind of metal glass glaze resistor. It is a resistor made of metal powder and glass glaze powder mixed and printed on the substrate by screen printing. Humidity and high temperature resistance, low temperature coefficient. It can greatly save the circuit space cost and make the design more refined.
The main advantage of the chip resistance is that it is convenient for mass mechanized production, saves a lot of production time, and mass mechanized production can greatly ensure the production efficiency and product consistency. With the continuous development of portable and mobile electronic devices, the miniaturization of electronic products and the development of low power consumption, the miniaturization of resistance is becoming more and more prominent, and the selectivity of patch resistance is more and more extensive than that of traditional plug-in winding resistance, with a volume of 01005. 0201040 2060 3080 5120 6121 0181 2201 0251 2. There are also long electrode patch resistors and liter power patch resistors, 0508,0612,1225,1210 and so on. There are also four-pin Kelvin resistors, etc., and the range of resistance values is also more extensive, from 0.02mR to 50G, and product customization can also be achieved.
Chip resistor brands are:
Suzhou WALTE Electronics (walter), the main production of alloy resistor, current check resistor, long electrode alloy resistor, four pin Kelvin resistor, alloy jumper resistor and so on.
VISHAY (vishay) is an American brand, mainly producing high-end precision resistors, alloy sampling resistors, shunt alloy resistors, Kelvin sampling resistors, thick film patch resistors, etc., in line with vehicle specifications AEC-Q200 patch resistors.
susumu is an early Japanese manufacturer of metal foil resistors, mainly based on metal foil patch resistors, covering alloy resistors, sampling resistors, wide electrode alloy sampling resistors, high precision film resistors, four terminal Kelvin resistors and so on.
ROHM (rohm) is a Japanese semiconductor company, is also an early manufacturer of patch resistors, patch resistors: shunt patch resistor, alloy patch resistor, metal film patch resistor, film patch resistor, side electrode patch resistor, thick film patch resistor, and so on, but also composite AEC-Q200 automotive grade patch resistor and so on.
YAGEO (yageo) is a passive component manufacturer in Taiwan, mainly based on chip resistance, and later covered the chip capacitor, chip inductance and so on industry chain, chip resistance has a number of series, there are car gauge chip resistance, anti-surge chip resistance, chip precision resistance, long electrode chip resistance, four-terminal precision resistance and so on
With the continuous expansion of industry and demand, there are more and more brand manufacturers, with the rapid advancement of device localization, especially the chip resistance is the first to go in front, there are many resistance brands, such as: Taiwan EVER OHMS (ever ohm), Taiwan Viking (viking), Taiwan Housheng (uinohm), Taiwan Wangquan (ralec), Taiwan Xinchang (pdc), Taiwan Huasinke (walsin), Guangdong Fenghua (fh) and so on.
The above is a rough introduction to the chip resistance brand, and there will be a more detailed individual brand introduction. If you need to know more, you can consult the relevant business. Shunhai Technology Co., Ltd. is a professional resistance agent seller, covering a complete brand, complete product models, goods in stock, welcome to cooperate.
The patch resistance consists of a deposited metal layer of 50 to 250 thickness on a ceramic substrate (using a vacuum or sputtering process). Thick film resistors have higher resistance per unit area than wire-wound resistors or Bulk Metal foil resistors, and are cheaper. When high resistance values are required and accuracy is moderate, thin film resistors are more economical and space-saving.
