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. HCL WIRE WOUND RESISTORS CERAMIC ENCASED TYPE TM ORDERING INFORMATION HCL CL-20 B 15R J 4.7 / 6.2 In case lug required is compatible with Amp F187 put down 4.7 after the tolerance and in case lug required is compatible with Amp 250 put down 6.2 after the tolerance. TOLERANCE RESISTANCE VALUE CHOICE OF MOUNTINGS (a) In case no bracket is required to be left blank. (b) In the event that bracket is required suffix the Type with `B' eg. CL-20B HTR TYPE SERIES 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.
