Mystery Component

From a box of engineering surplus from a client (so I can't just check their part number).

It's a 1210 package, orange, says

"DALE" "4R7"

9333

It ohms out to 1.0 ohms -- so it certainly isn't a 4.7 ohm resistor.

Does Dale make coils? Where to check?

Do you need to implement control loops in software?
"Applied Control Theory for Embedded Systems" gives you just what it says.

Yes they did. They are part if Vishay these days.

Most likely an inductor. 4R7 is likely to be the impedance at 100MHz.

Why not just measure it for inductance?

More likely inductance in nH?

That appears to be the right answer -- they have some 1210 parts that fit what I have, barring color.
