MSP08A0345K3FEJ Description

The MSP08A0345K3FEJ from Vishay is a high-performance thick film resistor network designed for precision applications requiring stable resistance values and robust construction. This 8-pin SIP (Single In-line Package) device features four isolated 45.3kΩ resistors with a tight 1% tolerance and a low ±100ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range of 25°C to 150°C. Encapsulated in a molded epoxy case, it offers excellent durability and thermal stability, with a maximum operating temperature of 125°C and a 100V voltage rating. The through-hole pin termination and 2.54mm terminal pitch facilitate easy PCB integration, while the 1W total power rating (0.3W per resistor) makes it suitable for power-sensitive designs.
