You'd have more luck looking at where it is located in the circuit than posting a picture a of brown brick with contacts either end. Its fairly chunky so sure it could be a ferrite of some kind (but they are normally black) or indeed a Fuse, self re

Flexible Circuit Board Finish ENIG or Hard Gold?

Gold should not be corroding in salt water. I have swum hundreds of miles in salt water with my wedding ring on my finger. My ring is a shiny and corrosion-free as the day it was cast over 120 years ago. It's possible that your gold thickness of 0.0

MPM Up2000 and SMEMA

Switched out the mech. relay on the board loader, no change. Same behavior. Could not find a mech. relay on the printer... SMEMA wiring appears go directly to a PCB. And it is at that point that I run out of talent. If the machine weren't dedicate

Suggestions for small and handy connector for in-circuit program

Electronics Forum | Mon Oct 24 09:07:58 EDT 2016 | robl

Could you make up your own adaptor cable to connect to your programmer, then fit a small form connector like a Firewire on the edge of the PCB? It should only take up about 7x7mm of real estate as opposed to a 2.54mm 5x2 pin header 12.7 x 5.08, or a
