CSI Current Sense Resistors

Bourns CSI Current Sense Resistors feature an electron-beam (EB) welded metal strip, low resistance, low temperature coefficient of resistance (TCR), and excellent long-term stability. These high-power modules offer a resistance range of <0.1mΩ to 3.5mΩ with ±1% to ±5% resistance tolerance and up to a 15W power rating in four package sizes: 2512, 3920, 4026, and 5930. The 2512 series size also offers low thermal electromotive force (EMF). Bourns CSI Current Sense Resistors are halogen free, RoHS compliant, and operate in a -55°C to +170°C temperature range. Typical applications include current sensing, voltage division, power modules, frequency converters, and industrial.
