TTI stocks high power current sense resistors from Bourns
Available in Europe through TTI, the CSS series of high power, current sense resistors is manufactured by Bourns.
The specialist distributor of electronic components offers the devices in two- and four-terminal versions. The two-terminal models are available in three different footprint sizes of 5930, 3920 and 2512 (6332 Metric). Resistance values are as low as 0.2 mOhm. Each family will have a range of low resistance options and power ratings of up to 15W.
The four-terminal designs allow for high precision four-kelvin resistance measurements and are available in size 4026.
The CSS series products have long term stability, low inductance, low thermal EMF, and are AEC-Q200 compliant. Custom versions are available upon request. Target applications include current sensing, battery management systems, power modules/motor controllers, as well as frequency converters.
Current sense resistors are growing in popularity due to their high measurement accuracy and relatively low cost compared to other technologies, reports TTI. The CSS resistors detect and convert current to an easily measured voltage which is proportional to the current through the device.
TTI is an authorised, specialty distributor of interconnect, passive and electromechanical (IP&E) components and distributes to industrial and consumer electronics manufacturers worldwide.
Globally, the company maintains two million cubic feet of dedicated warehouse space containing over 850,000 component part numbers. TTI employs over 5,400 employees and is represented in over 100 locations throughout North America, Europe and Asia.
