TYPICAL APPLICATIONS The HSVA 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 "Understanding pulse & over load capability of wire wound resistors". In case a tailor-made pulse resistor is required, please refer to "Questionnaire of data required from customers" and provide data accordingly. The HSVAU Series are very popular with stockists as they are capable of dual mounting - axial or vertical hence are instrumental in reducing inventory. ORDERING INFORMATION HSVA/HSVAU SV9A/SV9AU 4R7 K TOLERANCE RESISTANCE VALUE HTR TYPE SERIES 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 Type with `I', eg. SV-5AI.
