SMD Component ID

[glen65]

Hello,
I am working with a 3 phase motor controller
and ran across a 4 pin SMD component I am not familiar
with (see attachment). There is very little if any
resistance when measuring from end to end. The possibilities
I was thinking of was some sort of jumper or protection
device or perhaps an inductor. Anyone know exactly
what this is?

Thank You

I'd be guessing a reed switch or reed relay. Show another picture showing about 3x more board (as long as we can still see trace paths), and maybe we can confirm this, (or not).

Very high isolation optocoupler? Some sort of transformer?

If we learn from our mistakes I'm getting a great education!

High isolation optocoupler? Yep, that sounds good to. Maybe even better.


What is the product glen65, as that will also shed light on it.
