With the demand for MLCC TS18 & TS18H surging during past months, our mono capacitor, including radial type TS17R and axial TS17A, has been influenced seriously. For a better allocation of the limited materials, production lines and work forces, we have to make some important decisions as below:

1. To stop the production and quotation of TS17A temporarily;
2. All old offer of TS17R is losing invalidity and price would be marked up because of increasing cost of raw materials;
3. For TS17R orders, we will not accept payment terms any more, instead, full T/T in advance.

To sum up in conclusion, our lead time of TS17R series would be much longer on account of our overloaded production line. And worse situation is that we judge it would be getting even more critical with the growing orders. If you have real demand and stable requirement, you’d better place order for a whole year usage, or you would bear rapid rise of purchasing cost and unbearable longer lead time.

Our Suntan Technology always pay much attention on brand name building and marketing investment. Since year 2013, we even print out trademark Su on Multilayer (MONO) Ceramic Capacitor Radial Type . All the customers can indentify us by this logo, Su is a short name for Suntan. Here we would like to introduce TS17R to everyone.

Based on different material, Multilayer Ceramic Capacitors can be divided to a lot of series. 
There are some code name for each materail : NPO(COG), X7R,X5R,Z5U,Y5V,Y5U.

By refer to EIA standard, ceramic capacitors are break down into three categories: 
CLASS I : COG(NPO), also called “temperature compensation” type, It is temperature stable or compensating device, it shows very little or no changes in capacitance as temperature change, suitable for timing, impedance matching, ESD/EMI limiting. 
CLASS II : X7R,X5R,Z5U,Y5V, also called “high K” type, those material present greater capacitance change than class I type, a variety of dielectric materials are available thus the amount of capacitance change is to be defined from vendor to vendor.
CLASS III : is semiconductor type which exhibit capacitance change similar to class II, however, this type is very rare in consumer application.

Su Suntan A Bad Capacitor Story Ends Happily

---All kinds of Capacitors

I worked as a design engineer for an optical-telecom company that had deployed 1000 pieces of equipment worldwide. Having so many modules in the field means a trickle of returns, and it was my job to investigate the failures. One investigation taught me a wonderful lesson.

I received a module whose source of failure was easily identifiable: a charred tantalum capacitor. It failed short, making the whole multithousand-dollar module nonoperational. This surface-mount capacitor—with a 7343 footprint and 20V rating—was sitting on a 12V-dc plane. This failure rate of one capacitor in about 10,000 pieces in this time span was well below the statistical prediction. I took a picture of the fallen capacitor and considered the case closed.

In a few weeks, a customer returned a similar module with a charred and shorted capacitor in the same location. Even including this case, the failure rate was still below statistical prediction. I knew there were five more identical capacitors on the board, sitting in parallel on the same 12V-dc plane. In addition to the module's failure rate, I now had a one-in-six chance with the capacitors. So, I took another picture. I wrote a report to calm upper management, but I had a feeling that I'd better study reliability calculation in general and reliability for tantalum capacitors in particular, and the faster, the better.

In another few weeks, I received another failed module. The same capacitor looked bad. I had by now done my studying and could intimidate other people by saying long and complicated sentences about reliability, but why was it always the same capacitor? Overvoltage? Spikes? No way. The same plane contained plenty of sensitive stuff that would fry well before the capacitor even felt it. Having nothing better, I clung to the theory of excessive ripple current.

The idea of a temperature rise due to ripple current causing the failure gained traction when all three photos of the fallen capacitors revealed a common condition: almost no solder on each negative terminal. The electrical connection was still good, but there was little solder. The capacitor's positive terminal was fine with a fair amount of curvature-profiled solder. I started to promote the idea that the lack of solder had caused impeded thermal contact, but it was only wishful thinking. I calculated the worst ripple current: 10% of the maximum rating. On an operational board, I got less than 5%.

I had already dismissed other ideas—from excessive humidity to airflow turbulence. Suddenly, the picture of the layout popped up in my mind. The layout sections for the five good capacitors were identical: Vias were close to both terminals going down to an internal layer. The bad capacitor had a via at the positive terminal, but, at the negative end, there was a heavy trace going inside the footprint, beneath the capacitor, and only then outside. That's when I knew how to fit together all the pieces of the puzzle.

On the positive terminal, the solder stayed where it was supposed to, clinching the terminal to the PCB (printed-circuit board). On the negative side, however, during assembly, the melted solder drifted under the capacitor and solidified, lifting the negative end and bending the capacitor just enough to create a microcrack—a capacitor's well-known nemesis. I never felt as much excitement writing a technical report as I did the next day.
