SOMC16031K00GRZ

SOMC16031K00GRZ Description

The SOMC16031K00GRZ from Vishay is a high-performance thick film resistor network designed for precision applications requiring isolated resistor configurations. This 16-pin SOIC package integrates eight 1KΩ resistors with a tight tolerance of ±2%, delivering a combined power rating of 1.28W (0.16W per resistor). Its thick film technology ensures stable performance across a wide temperature range of -70°C to +150°C, with a low temperature coefficient of ±100ppm/°C for minimal resistance drift. The molded SOIC case with gull-wing termination enables reliable surface-mount assembly, while the 50V maximum voltage rating suits low-to-medium voltage circuits. Packaged in tape and reel (T/R), it is optimized for automated PCB assembly.

SOMC16031K00GRZ Features

• Isolated Resistor Network: Eight 1KΩ resistors with individual isolation (ISOL designator), reducing crosstalk in critical circuits.
• High Power Handling: 1.28W total power dissipation (0.16W per resistor), superior to standard thin-film networks.
• Stable Performance: Thick film construction with ±100ppm/°C TCR ensures reliability in fluctuating temperatures.
• Robust Packaging: Molded SOIC-16 case (11.18mm × 7.62mm × 2.03mm) with gull-wing leads for mechanical durability and solderability.
• Automation-Ready: Tape-and-reel packaging streamlines high-volume SMT production.
• Wide Operating Range: Rated for -70°C to +150°C, ideal for industrial and automotive environments (non-AECQ).

SOMC16031K00GRZ Applications

This resistor network excels in precision analog and digital circuits where isolation and thermal stability are critical:

• Signal Conditioning: Isolated voltage dividers in sensor interfaces (e.g., thermocouples, RTDs).
• Industrial Controls: PLC I/O modules requiring drift-resistant resistor arrays.
• Power Management: Feedback networks in DC-DC converters or LED drivers.
• Test Equipment: Calibration circuits demanding tight tolerance (±2%) and low TCR.
• Medical Devices: Isolated measurement systems where reliability is paramount.

Conclusion of SOMC16031K00GRZ

The SOMC16031K00GRZ stands out for its isolated thick film design, high power density, and thermal resilience, making it a robust choice for demanding electronics. While not automotive-grade (PPAP/No), its industrial-grade specs and Vishay’s quality assurance ensure long-term performance in harsh environments. Engineers will appreciate its balance of precision, power handling, and SMT compatibility, particularly in cost-sensitive yet performance-critical applications.
