BTC Development Corp. completes $253 million IPO on NASDAQ
MALVERN, Pa. - Vishay Intertechnology, Inc. (NYSE:VSH), a $2.07 billion electronic components manufacturer with a FAIR financial health rating according to InvestingPro, introduced a new surface-mount current sense resistor that delivers 5 W power rating in a compact 1206 case size. The Power Metal Strip WSLF1206 resistor features power ratings 20 times higher than standard resistors in the same footprint.
The new component provides power density exceeding 650 W/in², allowing designers to save board space in high power circuits without needing to use parallel resistance elements. It offers resistance values from 0.3 mΩ to 3 mΩ with tolerances of ± 1.0% and ± 5.0%.
According to the company’s press release, the resistor features a temperature coefficient of resistance (TCR) down to ± 75 ppm/°C, providing stable current measurement across temperatures from -65°C to +170°C. Its low resistance values help minimize power losses in end products.
The WSLF1206 incorporates a solid metal manganese-copper, nickel-chromium aluminum alloy resistive element with low thermal EMF (
The component is designed for current sensing applications in industrial motor drives, robotics, power tools, HVAC systems, uninterruptible power supplies, and computing equipment. It is sulfur-resistant, RoHS-compliant, and halogen-free.
Samples and production quantities are available now with lead times of 8 to 10 weeks.
