EBW5216 is a busbar-mounted shunt resistor for high current measurements in the hundreds of amps range. This product is an electron-beam welded resistance element sandwiched between large copper terminals with optional tin plating. The series offers values of 50 and 100μΩ at down to 1% tolerance, 150ppm/°C TCR and <1μV/°C thermal EMF.

Equivalent to Vishay WSBS5216, this part offers a robust shunt with the option of pressed pin terminals at the voltage sense points which permit through-hole attachment to a PCB. With a wide temperature range from –65 to +170°C and AEC-Q200 qualification, this component is ideal for a wide range of industrial and energy management applications.

Woking, UK, 31 May 2023 – TT Electronics, a global provider of engineered electronics for performance critical applications, today announced the EBW5216 series of shunt resistors for high current measurements in the hundreds of amps range. With a wide temperature range from –65 to +170°C and AEC-Q200 qualification, the EBW5216 series is ideal for a spectrum of industrial and energy management applications, including welding power supplies, motor drives, battery management, energy metering, and process control. Building on TT’s expertise in current sense resistors engineered to meet demanding accuracy targets, the EBW5216 family is a compact complement to TT’s EBW8518 and is busbar-mounted in a 5216 size.

EBW5216 is an electron-beam welded resistance element sandwiched between large copper terminals with optional tin plating. The series offers values of 50 and 100µΩ at down to 1% tolerance, 150ppm/°C TCR (measurement), 20ppm/°C TCR (alloy), and <1µV/°C thermal EMF. The EBW5216’s ultra-low ohmic values reduce power loss and its low self-heating reduces equipment temperature and improves reliability.

The idea behind machine vision, or artificial vision, is to enable industrial automation systems – via image processing – to perceive the outside world in a way that is completely analogous to the sight of a human being. Aimed at evaluating the salient features of the product under analysis, machine vision exploits the acquisition of images through cameras and their subsequent processing using image processing algorithms.

TT Electronics’ technology has proven successful in providing AEC-Q200 qualified resistors for EV applications such as battery charging and current sense. Learn why products like the ULW Series, and the LRMAP3920 and LRMAP5930 of low-resistance metal alloy power resistors are ideal for the EV landscape.

Robust metal strip able to withstand high temperature and high current, Power ratings up to 5W, Low TCR and Inductance, Resistance Range from 0.15mΩ to 10mΩ, RoHS compliant, AEC-Q200, Higher wattage devices feature PCB clearance gap to maximize thermal performance

“Aluminium nitride – with its wide area solder terminations – gives TT’s HPDC series our highest power density to date. With this product, our customers can reduce the size of their power conversion designs, while enhancing the reliability of the assembly through restricting the component hotspot temperatures,” said Brian Stephenson, Director of Engineering, TT Electronics. “These features make the HPDC family ideal for applications with high momentary load conditions, such as power supplies, motor drives, power amplifiers, and actuator controls.”

High performance and higher efficiency are common trends in most technologies, but particularly in transportation applications where the potential for significant environmental impact on a global scale is high. Greener, cleaner ideals are taking the lead in defining new goals for how technology must balance performance with environmental considerations. Electric vehicles and next-generation electric trains are working to meet the common goal to minimise their carbon footprint on Earth.

It’s an effort that demands attention to every facet of train design and development – with new systems facing constraints of size, weight, and integration with legacy systems. Following a common trend demonstrated successfully by high-speed national trains, railway scenarios such as subway, city, and intercity light rail systems are focusing on optimising all performance aspects of their traction and auxiliary units. This means tapping into advances in optoisolators that enable smarter designs and improved performance – scalable across fleets of trains, diverse routes, and broad geographic regions.

TT Electronics is making a change to the material of the insulation coating. There will be no change to the product form, fit or function of the device and this PCN is for notification only. To meet the various applications of customers, TT Electronics have developed an HV MELF Resistor with better environmental performance and more stable characteristics. The HV MELF has improved moisture resistance and is able to pass the strict test conditions of AEC-Q200. There will be no disruption to the supply chain. The new insulation coating will be used on product manufactured from December 2021. All products will be qualified in line with their respective datasheets and customer specifications. Qualification test reports will be available upon request.

There is no impact on product fit, form or function & there will be no disruption to the supply chain. All product qualifications will remain unchanged TT Electronics invites customers to communicate any specific test requirements to the business via their local sales contact. Customers are advised to continue ordering in line with their requirements. Orders placed from December 2021 will be supplied to the new specification or once stock in the supply chain is depleted.
