AMC1411: Input resistor

Barton Tung

Part Number: AMC1411

Hi expert,

My customer using AMC1411 placed a 39Ohm resistor at the input terminal pin.

with another 1uF capacitor at the front parallel with the Rsense.

I wonder what the purpose of those two extra components is.

Hi Barton,

These components make a low pass filter.

Hi Alex,

In fact, there's also a short comment below the 39Ohm resistor.

"Anti-s";

which the customer believes its for some sort of ESD protection circuit.

Any idea? Since this is a public form, i could not post their pic straight up.

Regards,

Barton

Hi Barton,

Anti-short perhaps?
