For example, some computers suddenly can not be turned on, it may be the IO chip fault, through the "run circuit", "detection card" detection to confirm the IO chip problem, the use of heat gun and other tools, take down the IO chip, replace the same type of IO chip welding on, to complete the repair; Or, if the triode on the hardware burns out, replace itThe chip screen query model is prepared, and the original category will be coded at the time of preparation. Therefore, most part numbers include a description of the type of the original.
2, GHz broadband amplifier, the original model uPC2711 (package mark: C1G). uPC2708 (Package identification: C1D) with the same structure and function. A pdf of the chip can be found at DATASHEET5.
3, usually, the screen printing of IC will clearly mark the following content: brandLogo, chip model, architecture information, lot number, date of manufacture (or date of manufacture), place of origin, and Pin1 logo, each clue points to the unique identity of the chip. Example analysis: STM32 chip silkscreen interpretation let chip silkscreen query model Let's look at a STM32 chip silkscreen example.
4, MV3581 is a patch SOP8 package of dual operational amplifier chip, its silk screen logo MV358I1. The chip can be used in various circuit applications, such as amplification, filtering, signal processing, etc. Double operation amplificationThe amplifier has two independent amplifiers that can process two input signals and output the corresponding amplified signal. With stable performance and high gain, the MV3581 chip is suitable for electronic devices and systems that require accurate signal amplification and processing.
Switching power supply thick mode chip models are very many, so here are a few examples: STR456A, STR541STR6020S, STR660STR-F645STR-F66600, STR-F670STR-G565STR-S630STR-S670STR-S6709, and so on. The most common is the 384x series, and older power supplies, 494/7500, are also more common.
digital-to-analog conversion. According to the announcement issued by the Silk Screen d73 official: As of April 2023, the silk screen d73 is a digital-to-analog conversion chip model, and the silk screen d73 belongs to the bidirectional Zener diode. Screen printing equipment is simple, easy to operate, simple printing, plate making and low cost, strong adaptability.
ThisThe chip is a frequency synchronous buck DC-DC regulator chip, the specific model is SY8009, and the output can reach 5A/2A. The following picture shows its pin diagram and typical application circuit.
Because the model is not the same, it is impossible to casually use a 371 can be replaced. Only the original 372 can be used.
IC/PDF query: http://this website provides a simple and easy to use query interface, can helpUsers search according to keywords, models, descriptions and other information. Users can enter the model number or keywords of electronic components, and then search for relevant product information, specifications, application notes, etc.
iPad can view the chip model through the "Settings" app. First, unlock the iPad and go to the main screen. Locate and tap the Settings app icon, which usually appears as a gear shape. In the "Settings" menu, scroll down and find the "General" option and click to enter. In the "General" menu, find the "About this machine" option and click to enter.
First, you can pass solidState the product model of the hard disk to find the master information. The SSD case is usually marked with brand and model information, which can be searched on the product website or other trusted electronic product database for more detailed specifications, including master chip information. Second, you can view the master control information through the hard disk management tool.
Check the model can go to the core check it, where in addition to check the model, you can also check the program, check the enterprise, check the alternative, study courses, etc., and the mall can directly purchase, if there are problems, you can also go to the planet X to consult the electronics industry.
