MicroCrystal RV-8803 – A Really Accurate RTC June 17, 2019- RTC chips traditionally were the domain of Maxim and NXP. Switzerland-based MicroCrystal recently made quite a buzz with its RV-8803, which offers simple integration, an I2C interface and extreme accuracy. Let us start out by looking at a system overview. Figure one shows how this I2C RTC is made up internally – interested observers note […] Analog Devices’ LTM2887 – If a Digital Bus Needs Galvanic Isolation June 15, 2019- In theory, digital buses are intended to connect things to one another. Sadly, one sometimes wants but a logical connection – in many cases, galvanic isolation helps out. Should you ever feel like isolating very fast buses, definitely give the LTM2887 a chance. From a technical point of view, Linear Technologies attempt at entering the […] AVAGO APDS-9008 or APDS-9005-020 – Keeping an Eye on Ambient Light June 14, 2019- Recent times saw quite a bit of interest for part numbers such as the APDS-9008 or APDS-9005-020 – they are a very interesting type of ambient light sensor. One of the oldest questions in regards to light sensors involves their spectral sensitivity. If a part is to output but one voltage level, the conversion between […] STMicroelectronics’ LIS2DH12 – Low Power Motion Sensing June 12, 2019- Apple’s iPhone introduced gyroscopic sensors to a wider range – before that, accelerometers were not commonly found in consumer hardware. STM sells excellent parts which, however, get little media attention – time to take a look at the LIS2DH12. Integrating the part into your circuit as an MPU6500 alternative or MPU9500 alternative is not difficult. […] Panasonic AMG8833 – FLIR for cheap June 7, 2019- FLIR made infrared thermal sensors cool – sadly, their parts are all but cheap (and suffer from export control problems). Panasonic’s Grid-EYE family is a low-resolution alternative which comes at significantly lower cost. From a technical point of view, Panasonic’s image sensor could not be simpler. We are looking at an 8×8 sensor with an […] DipTronics DTS-62R-V – Small Switch, Very Big (and Very Cheap) June 5, 2019- When yours truly was but a lowly cadet, various US manufacturers produced (pricey but quite reliable) switches. Chinese vendors recently started to catch up – seeing the DTS-62R-V top our customer interest list shows that the run stage of the crawl-walk-run cycle is reached. DipTronics has been around the Asian switch market for ages, exhibiting […]
Capacitor prices… all hands on deck, brace for impact!
MLCC capacitor troubles are real: since Murata decided to exit the market, prices go up. A similar trend can also be seen in flash memory.
Memory prices have long shown themselves to be subject to the “pigs cycle”. This is shown by looking two types of flash memory originally developed by Cypress, both of which are hit by supply problems…
An interesting aspect is that manufacturers focus on efficiency: older or “larger” products are eliminated in favor of smaller ones which can be produced with less resource outlay.
For example, take a look at the S25FL132K0XNFI013; a venerable SPI flash memory, which recently got hit with the hammer of discontinuation. At least, an application note available here provides some information on alternatives.
The MLCC capacitor situation, which we discussed recently – has not improved much. It takes but one look at the OEMSecrets toplist to see that MLCCs still are among the most-searched parts, with more than 25% of the toplist being populated by capacitors of one form or another.
While you might be tempted to claim that your systems are safe – you, after all, use MicroSD memory cards and electrolytic capacitors – be advised that this is untrue. MLCC capacitors and flash memory are used all over the place: one customer of yours truly and recently was hit 20% price increase on the process computer used to power his GPS tracker.
What to do?
Randomly stockpiling parts usually is an inefficient coping strategy. Sevelopers should instead keep prices of commonly used parts on the radar: if they suddenly start to rise, targeted stockpiling can be a good idea.
One way to find out about price trends is provided by TTI – the Berkshire-Hathaway owned company provide a list of of useful bits of info here.
Better stock up if the exclamation mark shows up
