Resistors over the entire resistance range given are available in a
range of temperature co-efficients from ± 200ppm/°C to ±1500ppm/°C depending on the resistance value
chosen.
Profile Dimensions
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 gray; colour which are inherent to these ceramic materials.
These resistors are available in a choice of four
mounting configurations
1) With unkinked leads.
2) With preformed leads.
3) With cropped leads.
4) With HSV mounting pillar.

All Dimensions in mm
Resistors with preformed leads can be identified by the
suffix 'P' e.g. 9 watt resistor with preformed leads is HTR type, 'SV 9P'.
Resistors with cropped leads can be identified by the suffix 'C' e.g. 7 watt resistor with
cropped leads is HTR type, 'SV7C'.
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 SV5M.
