Resistors resistors are also known as surface-mount devices or SMD resistors and can be designed in square or rectangular chip bundles. A chip resistor can have a definite value of resistance or a flexible, more variable resistance within a specific range. It is important to note that it is a passive component that can only decrease current or voltage signals. To better understand why such devices are garnering popularity, we must cover how they work. As they form the main components of many advanced electronics... (read more)Browse Resistors Datasheets for ASAP Semiconductor LLC -

ExxonMobil Chemical Company - Synthetic Base Stocks
Continuously variable transmission fluids A continuously variable transmission (CVT) is a belt-and-pulley system that provides infinite gear ratios. This transmission style was popularized by vehicle manufacturers in Japan but is becoming common in the US and other markets. Constant metal-on-metal traction is required to avoid slippage in the belt-and-pulley system while also minimizing friction for energy efficiency. Like other types of transmission oils, CVT fluids are moving to lower viscosity - lower than 6 cSt kinematic viscosity...
