Document Number: 30122

THIS DOCUMENT IS SUBJECT TO CHANGE WITHOUT NOTICE. THE PRODUCTS DESCRIBED HEREIN AND THIS DOCUMENT

Low Value (Down to 0.0005 Ω), Surface-Mount

LINKS TO ADDITIONAL RESOURCES

FEATURES

• Very high power to foot print size ratio (3 W in

2512, 2 W in 2010, 1 W in 1206, 0.5 W in 0805,

and 0.4 W in 0603 package)

• All welded construction of the Power Metal

sensing,

voltage

division

and

pulse

applications

• Proprietary processing technique produces

extremely low resistance values (down to

0.0005

Ω)

• Sulfur resistance by construction that is

unaffected by high sulfur environments

• Very low inductance 0.5 nH to 5 nH

• Low thermal EMF (< 3 μV/°C)

• Material categorization: for definitions of compliance

Notes

• This datasheet provides information about parts that are RoHS-compliant and / or parts that are non-RoHS-compliant. For example, parts

with lead (Pb) terminations are not RoHS-compliant. Please see the information / tables in this datasheet for details

Notes

• Part marking: value; tolerance: due to resistor size limitations some resistors will be marked with only the resistance value

Ω to 0.00099 Ω is only available with 2 % tolerance (G tolerance code)

Notes

• Per PCN-DR-00009-2022-REV-0, WSL marking will be removed effective March 1st, 2023

non-standard packaging codes are identical to our standard EA (lead (Pb)-free) and TA (tin / lead), except that they have a package quantity

of 1000 pieces
