Construction
Black type
A low TCR resistance alloy plate, with plated connection bands is
protectively coated and numerically marked with the resistance value.
This part has standard plated end connections and is suitable for wave
or IR reflow soldering.
Green type
A low TCR resistance alloy plate is grooved to set the final resistance,
the lower faces are solder plated for connections, and it is protectively
coated and numerically marked with the resistance value. This part is
ONLY suitable for IR reflow soldering.
Marking
For values which are integer numbers of milliohms, the marking is
4-character IEC62 code; e.g. “R002” for 2mΩ, “R010” for 10mΩ.
For values including fractions of a milliohm the marking is 3 or 4-
character code using “M” to indicate the decimal point, e.g. “M75”
for 0.75mΩ, “1M50” for 1.5mΩ.
