The total inductance of a chip capacitor is determined both by its length to width ratio and by the mutual inductance coupling between its electrodes. So, a 1210 chip size has a lower inductance than a 1206 chip. Check with your supplier for recomm

We are having problems with a 1210 cap moving as far as a 1/4 inch from its pads during reflow. We have verified the placement before reflow. They will tombstone some of the time. There are smaller and larger parts around this location and none of th

No problem. If you get no joy you're going to have to change the footprint to a 1206 or 1210. Murata have a range of high Q value inductors (50-60) & from memory Toko used to be pretty hot too. The terminations on the coilcraft part are listed a

We use a FKN pizza cutter and found that even with 5mm clearance and the proper orientation of the part larger ceramic capacitors 1812, 1210 would still stress fracture. We have successfully fixed stress fracture problems by adding routed relief slot

Hi I have solved the issue. The component cracking are the big 1210, 0603 and 0402 capacitors. After studying and testing in many type of solder. The best to use is SnPb and the components are the key - there are component which will tend to expand

Greetings to all. We are currently experiencing cracking of the ceramic capacitors, on both primary and secondary sides of the PWB. The components range in size from 1206, 1210, to 1815s. The cracks do not appear to alter the electrical properties

Re: wave soldering surface mount tantalum and ceramic capacitors

Electronics Forum | Fri Feb 05 09:39:58 EST 1999 | Dave F

Can anyone help me with the pros and cons of trying to wave solder tantalum and large (1812) ceramic capacitors. I do know that one may see fractures on larger cermaic caps, but have not seen much on the tantalums. Any insight as to what proble
