Resistance Tolerance(Matching)
Resistance value, in ohm, is expressed by a series of 5 characters, 4 of
which represent significant digits while the 5th R or K is a dual purpose
letter that designates both the value range (R for ohmic;K for kilo-ohm)
and the location of decimal point.

Example of Applications
An Application of Type SLD (Input feed-back resistors for amplifiers)
Because the input and the feedback resistors are incorporated into one single
element, amplification is not affected by temperature change.
