Housing for resistor?
Housing for resistor?
I have some metal film 1/2w 2.2ohm resistors in some car wiring. I'm concerned about the durability of this install and am seeking advice on how to protect the resistor once it's soldered in place. The obvious is heat shrink tubing, but it's there anything more substantial?
I'll be using these resistors in a custom pigtail that will plug into the car wiring. 3D printed housing? I have tried searching and I haven't found anything like that.
You're viewing a single thread.
You can get small project enclosures to put them in. Some PVC pipe and end caps could also work.
I would probably just use some good quality, adhesive heat shrink if they are out of the way though.Adding on to this line of thinking, maybe a thin plastic tube and epoxy to encase it with the solder joints. (Bonus points for using thermal epoxy, since it is a resistor after all.)
I have seen Bigclive on YouTube encase resistors and a diode rectifier in standard epoxy for use in lighting, so heat probably won't be an issue now that I think of it.
This is intriguing and I'm going to think about this.
I tried finding the video, but I cannot.
It's the same concept as potting PCBs with black epoxy. Of course, it helps to be aware of heat sensitive components but China never cares about that.
Google for Epoxyseal 9000, if you want something proper.
