Vishay's new WSLP12061W surface mount PowerMetalStripTM resistor is the first device in the 1206 package KNB1-32 Miniature Circuit Breaker
KNB1-32 Mini Circuit breakers, also named as the air switch which have a short for arc extinguishing device. It is a switch role, and also is a automatic protection of low-voltage electrical distribution. Its role is equivalent to the combination of switch. Fuse. Thermal Relay and other electrical components. It mainly used for short circuit and overload protection. Generally, According to the poles, mini Circuit breaker can be divided into 1P , 1P+N , 2P, 3P and 4P.

Recently, Vishay Intertechnology, Inc. (NYSE: VSH) announced the launch of a new surface mount PowerMetalStripTM resistor , the industry's first 1W current sense resistor in an ultra-small 1206 package. The WSLP1206 resistor has an ultra-low resistance range of 2mΩ to 50mΩ and is resistant to temperatures up to 170C.
The small size of the WSLP1206 resistor allows it to replace larger current sense resistors, enabling space savings on the board, which will create smaller, lighter weight products for consumers. The device is mainly used for current sensing and pulse applications in computer DC to DC controllers, notebook VRM and lithium ion battery safety and management systems; electronic vehicle systems, including engine control, multimedia electronics, climate control and anti-lock braking Dynamic system.
The WSLP1206 is manufactured using a proprietary technology that achieves extremely high power and ultra-low resistance values ​​using an all-weld structure with solid metal nickel-chromium or manganese-copper alloy resistor elements. The resistor has an ultra low inductance of 0.5nH to 5nH, an excellent frequency response of 50MHz, and a low thermal EMF of less than 3μV/C.
