The Matsuo date code is explained in more detail in their other datasheets, such as p. 2 of the . The codes repeat every 4 years: The 12 uppercase letters A through M (minus "I") represent the 12 months Jan through December for one of the years 1997, 2001, 2005, 2009, 2013, 2017, ... The 12 uppercase letters N through Z (minus "O") represent ...
The part code is completely irrelevant. The full part name is posted on the wheel or the tube as long the parts are on the shelf. The full name is in the PCB files as soon the part is used. What's not in the PCB files is the date code. That is because manufacturing PCBs is usually not done in the design house.
Nichicon, like many other manufacturers, typically uses a date code to indicate when a capacitor was manufactured. The format may vary slightly between manufacturers, but generally, it includes both a letter and numbers. In your example, the date code "B1538" can be broken down as follows: The letter "B" likely represents the month of manufacture.
Common marks - many larger ICs will have some form of date code (1819 in your second example is likely a date code). Very small ICs may omit it or shrink it down into a vendor-specific format. Some garden-variety SMT devices use a three-character alphanumeric code to describe the device (small transistors or MOSFETs).
2. I have a 5HP 3-phase electric motor with the following model number / code: WVK 184T TDR 7026 DG. It would be nice to decode this fully, but mainly I'm interested in its age to help judge its condition & the age of the equipment it powers. Here's the full nameplate: and motor: Based on materials I can find so far it looks like the first 3 ...
I'm trying to find the date code or lot trace code for this chip. The top of the chip shows the part number (obviously) and an 8-digit alphanumeric string of characters above the part number. Texas Instruments' website says that their lot trace codes are 7 digits. If the 8-digit number isn't the lot trace code, what is it?
Tantalum Cap Code Explained. I need to replace the following cap: It was placed at the input of a device that runs off 24Vdc, like the following schematic. simulate this circuit – Schematic created using CircuitLab. I'm repairing the unit after an explotion due to a maintenance where the board was fed 220Vac instead of 24Vdc...
7. The solution is to call both GetTime and GetDate at the same time, If you call only GetTime it does not update correctly: HAL_RTC_GetTime(&hrtc, &currTime, RTC_FORMAT_BIN); HAL_RTC_GetDate(&hrtc, &currDate, RTC_FORMAT_BIN); I don't know how they are connected, even more so because GetDate () is run after GetTime () and it still makes difference.
A bit late reaction, so I guess you've found out by now, but for completeness: WR5 in SOT23 = BZX84-B6V2, 6.2V zener, by Philips. A7W in SOT23 = BAV99, dual diode, by Philips. 1E in SOT23 = probably BC847A, NPN transistor, by Philips, but may also be either: CM9NB847A, NPN transistor, by Canaan Microelectronics. FMMTA43, NPN transistor, by Zetex.
The small ceramic capacitors with 2 digits markings can be identified with their color and the type of markings: Generalizing, The small brown capacitors have written with the value of the capacitance with a multiplier 10^ (-12) i.e. picofarad. The capacitor with value written as 1n0, 2n2, 47n means : 1n0 = 1.0nF.
