TYPICAL APPLICATIONS
HCL Series has been developed in far east as a direct replacement for old style radial wire wound resistors. As they
can be provided with fitted mounting brackets they are suitable for use in situations where shock and high
frequency vibration forces are to be encountered.
HCL Series also offers the following advantages -
a) High degree of insulation; b) Low surface temperature as the bracket itself acts to some extent as a heat sink.
These resistors can also be supplied with a choice of receptacle type terminals which are compatible with AMP
connector F187 and 250. Please refer ordering information.

Note :
Due to recent technological advances, the ceramic cases used may be steatite ceramic / corderite ceramic /
high alumina ceramic depending on the nature of the application. Hence the ceramic cases may be off-white /
variations of brown and variations of grey; colours which are inherent to these ceramic materials.
