TYPICAL APPLICATION
These resistors find wide application in Inverters and Power supplies.
Due to the nature of their construction, they can withstand surges quite efficiently. Please refer to
“Understanding pulse
& over load capability of resistors”.
In case a tailor made pulse resistor is required, please refer
Questionnaire of data
and provide data accordingly.
The HMVL series offers a practical solution to current sensing applications where PCB space is at a premium and low
inductance is required. Please ensure that resistance value is checked using 4½ digit micro ohm meter with 4 wire system
and insulated clips.
For the effective utilisation of these resistors, please refer
"Applications / Design notes for current sense resistors”.
Note : 1)
Type LV10L can be provided with 1.0mm leads if required, please specify at the time of placing of the order.
2)
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.
