LVC Series
Low Value Chip
Ohmite’s LVC Series low value chip
resistors are ideal for today’s current
sense applications requiring low profile,
low cost solutions. Available in 0.5,
0.75, and 1 watt sizes, footprints are
1206, 2010, and 2512 size respectively.
These resistors are offered in ohmic
ranges from 0.10 to 4.7 ohms in stan-
dard 1% and 2% in E12 values depend-
ing on value.
The LVC Series resistors are well
suited for a variety of industrial and
commercial applications.
