Bourns, Inc. announced a new current sense resistor model designed for applications that require lower power, smaller footprint solution. Designated Bourns' model CRF0805, the new device is the smallest surface mount current sense resistor in Bourns' industry-leading CRF family of resistors. Featuring a power rating of just 0.5 watts and a resistance range from 5 milliohms to 20 milliohms, the new model helps meet the ongoing demand for smaller and denser circuit boards. Bourns’ fixed resistor products are used to detect and convert current to an easily measured voltage, which is proportional to the current through the device. Current sense resistors offer an optimal solution for designs requiring low inductance and tighter precision for improved reliability and longer life such as power supplies and stepper motor drive applications.
The Bourns' CRF0805 model is RoHS compliant and features an operating temperature range of -55 °C to +170 °C and temperature coefficient of ±100 PPM/°C. Additional specifications are noted in the table below.
CRF0805 model is priced from $0.18 in 25,000 piece quantities and is available now.
