WIRE WOUND RESISTORS
CERAMIC ENCASED TYPE
The HSV A Series enjoys a wide market in TV, power supply and industrial electronics field.
Depending upon the resistance value and application the resistor core may be fibreglass or ceramic.
These resistors also available for use in pulse applications. For further information please refer to
In case a tailor-made pulse resistor is required, please refer to
and provide data accordingly .
The HSV AU Series are very popular with stockists as they are capable of dual mounting - axial or vertical hence
are instrumental in reducing inventory .

Note : Due to recent technological advances, the ceramic cases used may be steatite ceramic or corderite
ceramic or high alumina ceramic depending on the nature of application. Hence the ceramic cases
may be off-white or variations of brown and variations of grey; colours which are inherent to these
ceramic materials.
In case Pulse type is required please suffix HTR T ype with ‘I’, eg. SV-5AI.
