Ambient Temperature
Resistance value, in ohm, is expressed by a series of six characters, five of
which represent significant digits. The sixth 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.

Precaution in Using HK or HL Resistors
When soldering to mount HK or HL on a board, keep the resistor over 10mm away from
the board surface by using an insulating tube.
