Ohmite LVK12R005FER Low value chip Datasheet

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 standard 1% and 2% in E12 values depending on value.
The LVC Series resistors are well
suited for a variety of industrial and
commercial applications.
