SOMC160322K0FEJ Description

The SOMC160322K0FEJ from Vishay is a high-performance thick film resistor network designed for precision applications requiring stable resistance values and robust thermal performance. This 16-pin SOIC package features 8 isolated 22KΩ resistors with a tight 1% tolerance and a low ±100ppm/°C temperature coefficient, ensuring reliable operation across a wide temperature range of -55°C to +150°C. With a total power rating of 1.28W (0.16W per resistor) and a maximum voltage rating of 50V, this network is ideal for demanding circuits requiring isolation and consistent performance. The molded, gull-wing termination design enhances mechanical durability and facilitates surface-mount assembly (SMD) in compact PCB layouts.

SOMC160322K0FEJ Features

• High Precision: 1% tolerance and ±100ppm/°C TCR for stable performance in varying environments.
• Robust Construction: Molded SOIC package with gull-wing leads for mechanical strength and solderability.
• Isolated Resistors: 8 independent 22KΩ resistors (ISOL circuit designator) prevent cross-talk in sensitive applications.
• Wide Temperature Range: Operates from -55°C to +150°C, derated up to 150°C for high-reliability use.
• Surface-Mount Ready: 16-pin SOIC with 1.27mm pitch for compatibility with automated assembly processes.
• Compliance: EU RoHS compliant (with exemption) and EAR99 ECCN, though contains SVHCs above thresholds.

SOMC160322K0FEJ Applications

This resistor network excels in:

• Analog Signal Conditioning: Precision voltage dividers and feedback networks in op-amp circuits.
• Industrial Controls: Isolated measurement systems, PLCs, and sensor interfaces requiring drift-free resistance.
• Power Management: Load balancing and current-limiting in DC-DC converters or power supplies.
• Automotive Electronics: Non-automotive grade but suitable for benign-environment automotive peripherals.
• Medical Devices: Diagnostic equipment where stable resistance and isolation are critical.
