4608M-102-391LF Description

The 4608M-102-391LF from Bourns Inc. is a high-performance 4-resistor network designed for precision applications. Part of the 4600M series, this through-hole-mounted array features 390Ω resistors with a tight ±2% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across varying environmental conditions. Its isolated circuit type eliminates crosstalk between resistors, making it ideal for signal integrity-critical designs. The compact 0.798" x 0.098" (20.27mm x 2.49mm) footprint and 8-pin SIP configuration optimize space efficiency on PCBs. Compliant with ROHS3 and REACH standards, it is suitable for global markets.

4608M-102-391LF Features

• Precision Resistance: 390Ω ±2% tolerance for accurate voltage division and current limiting.
• Low Drift: ±100ppm/°C TCR and 50ppm/°C resistor-ratio drift ensure minimal deviation over temperature fluctuations.
• High Power Handling: 400mW per resistor (1.6W total) supports robust operation in demanding circuits.
• Isolated Design: Independent resistors prevent interference, ideal for multi-channel systems.
• Durable Construction: Not MSL-rated (non-moisture-sensitive) and through-hole mounting enhance reliability in harsh environments.
• Compact SIP Package: Saves board space while simplifying assembly.
