Re: OT Resistor identification


 

It could be a 4mR resistor. ROHM makes SMD shunt resistors in that range. "4L0" would indicate a 4mR resistor, 5% tolerance in the PMR Series.

See the datasheet here:

I have a battery BMS that I am reverse engineering.
I have a resistor with a code that I have never seen and cannot find any
information on.
The resistor is a SMT device marked 4L0.
The L appears to be a multiplier.
The resistor measures as a short with the equipment that I have.
I suspect that the resistor is in the milli Ohm range.
Could be 0.004 or 0.0004 Ohms or others.
This does not comply with the EIA-96 format, that I can see.

Any help??

Thanks
Glenn
