Introducing Vishay's Innovative Power Metal Strip Resistors
Vishay Intertechnology has unveiled an exceptional lineup of AEC-Q200 qualified Power Metal Strip resistors, setting a new standard in the market. These devices, characterized by their exceptional temperature coefficient of resistance (TCR) as low as ± 10 ppm/°C, are ideal for diverse sectors, including automotive, energy, and industrial applications.
Key Features of the WSBE Series
The WSBE series shunt resistors come in resistance values as low as 15 µ? and power ratings reaching 50 W, making them a powerful option for demanding applications. The remarkable low TCR is achieved through a carefully engineered design that combines a solid metal resistive element with Vishay's patented TCR mitigation technology. This innovation not only enhances accuracy but also reduces the complexity traditionally linked with temperature compensation and calibration processes.
Applications and Benefits
WSBE resistors are excellently suited for battery management systems (BMS), where they can significantly cut down on the need for temperature sensors and complicated software calibration during the production phase. This simplification benefits the charging infrastructure for electric vehicles (EVs) and hybrid electric vehicles (HEVs), such as motorcycles and golf carts. Moreover, these resistors find use in energy monitoring systems, large battery setups, battery backups for uninterruptible power supplies (UPS), industrial motor drive inverters, and even satellite technology.
Design Improvements and Component Reduction
With an all-welded construction, the WSBE resistors provide exceptionally low inductance values of less than 5 nH and low thermal EMF, which can go down to less than 1.25 µV/°C. They operate effectively in a broad temperature range from -65 °C to +170 °C, adhering to RoHS compliance and being halogen-free, further emphasizing Vishay's commitment to environmentally responsible products.
Device Specifications and Ordering Information
Available in two case sizes, 8518 and 8536, the WSBE series resistors possess remarkable lifetime stability of 1%, ensuring reliability over long-term use. Each resistor is rated for high current capabilities, handling currents up to 1825 A without observable resistance shifts.
Currently, samples and mass production quantities are readily available, boasting a lead time of 30 weeks. Vishay is a leader in the manufacturing of a broad spectrum of discrete semiconductors and passive electronic components that are crucial for cutting-edge designs across various sectors such as automotive, aerospace, and telecommunications.
Vishay Intertechnology, showcased under the ticker symbol VSH on the NYSE, emphasizes its tagline, "The DNA of tech," as it continues to contribute to the advancements within the electronic component landscape.
