Ultra-low Ohmic Chip Resistors for Current Detection: PMR10/18 series | New product new technology

Overview | Features | Applications | Lineup

Ultra-low ohmic (2-10mΩ) chip resistors in compact 2012 and 3216 sizes for current detection

Overview

Resistive elements comprised of a special alloy are used for ultra-low resistance (2-10mΩ) and low TCR characteristics, while unique process technologies result in significantly higher voltage ratings compared with similar-sized products, allowing smaller resistors to be used for greater miniaturization of next-generation mobile devices.

Features

PMR10(2012) : 0.5W, 2-10mΩ
PMR18(3216) : 0.75W, 2-10mΩ
±1% (F class) and ±5% (J class) products available
Temperature Coefficient of Resistance (in ultra-low resistance range): ±150ppm/ºC
Operating temperature range: -55ºC to +155ºC

Applications

Power supply control in notebook PCs, digital cameras, HDDs, and other compact devices
Remaining battery level detection
Current detection in general-purpose power supplies, overcurrent detection
