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.
