Has anyone had issues with Renco inductors failing. The component I'm having problems with is a 330uH shielded power inductor. Out of 36 board failures, I have 17 that failed because this inductor failed. Most often they end up reading -1.34 uH.

After wash cycle, some of the inductors are open (broken wire). Resistance across the two ends should be below 4 ohms (normal) however on broken wire shows above 200 ohms. I am wondering if anyone else has seen this problem. We are using High-Reliabi

I don't think it's a stencil issue. You have an identical inductor next to t=it, that's perfectly straight. You have a problem in that location. I've seen some inductors be affected by slight magnetic forces in the reflow oven. Try to rotate the boar

I am unable to find a reliable source to determine the amount of package damage allowable on an SMT coil inductor with a ceramic case. Where can I find information of this nature.

Does anybody have a slick way to hold down large inductors? Like 2 to 3 inches in diameter. There must be something better than ty-wraps and RTV.

We already tried that. The sugar seems to have a bad reaction with the varnish on the Inductors. Do they make a sugar-free version?? Can you send me some samples??

DaveF, would the adhesive be strong enough to keep the part from vibrating free over time? DO you know any part numbers? These inductors have quite a high mass. I would profer to lay them down on thier side but there is not enough room.

Found the issue. The footprint is incorrect. The inductor completely shields the paste from heat. Slid the inductor on the pad to expose the pad and paste, and perfect solder joint. This part was a last minute design change with a larger body.

if the inductors were your only problem. My mom wouldn't be pleased with the V30200C dual voltage rectifier just below the inductors

Hello, has anyone had issues with uncoated ferrite smd inductors corroding/rusting from di water wash?
