Table 3
Adjustable Resistors
(see Figure 9)
Adjustable resistors use the same basic construction as fixed
resistors already described, and have a window in the vitreous
enamel through which contact is made to the resistive
element by a sliding contact band. The band is fitted with a
clamping screw and nut to retain it firmly in position.
The adjustable winding style has a maximum permissible hot
spot temperature of 300°C and the maximum dissipation, for
an ambient temperature of 20°C, is specified in Table 4. The
partial open winding necessitates a reduced maximum
resistance, when compared with fixed resistors, and the
resistance range is also defined in Table 4.
More than one adjusting band can be fitted, up to the
maximum number specified in Table 3.
Adjustable resistors are available in termination styles B, 4B,
AP, C, CB and CP, in sizes 1602 to 1609 inclusive and 1906
and 1908 denoted by prefix ‘V’.

All other details of the electrical and environmental
performance of adjustable resistors are the same as for
fixed resistors.
