CONSTRUCTION
The resistors are constructed out of a high-grade ceramic
body. Internal metal electrodes are added at each end and
connected by a resistive paste. The composition of the
O U T L I N E S
For dimension see Table 1
paste is adjusted to give the approximate required
resistance and laser cutting of this resistive layer that
achieves tolerance trims the value. The resistive layer is
covered with a protective coat and printed with the
resistance value. Finally, the two external terminations
(matte tin) are added. See fig. 4.
