Resistors with cropped leads can be identified by the suffix 'C' e.g. 7 watt resistor with cropped leads is
HTR type, 'SV-7C'.
Resistors to be fitted with vertical mounting pillar can be identified by the suffix 'M' e.g. 5 watt resistor
with mounting pillar is HTR type SV-5M.
In the case of SV7, SV9, SV11 & SV17 there is a possibility of fitting 2 vertical mounting pillars. These can
be identified by the suffix “MM” e.g. SV17 with 2 vertical mounting pillars is HTR type SV17MM.

ORDERING INFORMATION

TYPICAL APPLICATIONS

“Understanding pulse & over load capability of wire wound resistors”.

"Questionnaire of data required"

The HSV series enjoys a wide market in TV and power supply field especially where space is at a premium on the PCB.
Depending upon the resistance value and application the resistor core may be fibreglass or ceramic.
These resistors are also available for use in

Pulse applications

. For further information p

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 the 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 a tailor- made pulse resistor is required, please refer to

and provide data

accordingly.
