MSP08A03390RJEJ Description

The MSP08A03390RJEJ from Vishay is a high-performance thick film resistor network designed for precision isolation circuits. This 8-pin SIP (Single In-line Package) device integrates four isolated 390Ω resistors with a 5% tolerance, offering a total power rating of 1W (0.3W per resistor). Encased in a molded epoxy housing, it ensures durability and thermal stability across a wide operating temperature range of -55°C to +125°C (derated up to +150°C). Its ±100ppm/°C temperature coefficient and 100V maximum voltage rating make it suitable for stable, high-reliability applications. Compliant with EU RoHS and classified under ECCN EAR99, it is ideal for industrial and commercial electronics.
