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.
