I cannot find the proper sized High Frequency-pulse rated High Voltage dv/dt snubber capacitor. The problem is that I know what the required electrical rating is, but the problem is that the dimensions of the capacitors found will not match the critical space layout of the printed circuit board. The dimensions are: 25mm L x 9mm W x 19mm H. Lead spacing is 24mm. An attachment to show what the capacitor looks like.
Hello Norloonda2,
Thank you for posting on the TechForum.
I could not find a snubber capacitor in the size you listed.
These are the snubber capacitors we have available.
Thank you Nathan but the sizes that I have viewed so far, even with DigiKey selections will not work for me because space requirements are critical. It’s within an 1989 RCA Colortrak 2000 Stereo monitor console.
Again, thank you for your time and consideration,
Jonathan Wright
You did not state the capacitance or voltage ratings you were looking for, but the capacitors in the link below will fit your space requirements of 25mm X 9mm X 19mm. The lead spacing is slightly different but is close enough you should be able to bend them slightly with pliers to get them to fit. The only thing that this will do is make them slightly shorter but that usually isn’t a problem when your space is small anyway.
Thank you, Shawn, I greatly appreciate your assistance. I’m hoping to find somewhere Panasonic ECWH16153JV or ECWH20153JV. The capacitance is 0.015uF @ 1600 /2000VDC. I looked at the table, and I do have a couple of good fallback selections from Cornell Dubilier (CD). When I have exhausted all practical distributors w/o MOQ’s, who have it, I will scrutinized those CD caps and finalized my purchase. JW
We carry the ECW-H16153JV which can be ordered in quantities down to 1. Unfortunately though we carry the ECW-H20153JV minimum of 200 is required to order and lead time is currently sitting at 21 weeks. Good luck with your project!
Thank you Shawn. Fortunately, I found and placed an immediate purchase for the ECWH16153JV with “Onlinecomponents.com”.
Again, Thank you for helping me. I still need to find four (4) more components for my project.
Regards,
J. Wright
