SOMC1603820RGDC

SOMC1603820RGDC Description

The SOMC1603820RGDC from Vishay is a high-performance thick-film resistor network designed for precision applications requiring stable resistance and isolation. This 16-pin SOIC package features 8 isolated 820Ω resistors with a tight 2% tolerance and a low ±100ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range of 70°C to 150°C. With a 1.28W total power rating (0.16W per resistor) and a 50V maximum voltage rating, this network is engineered for demanding circuits, particularly in isolated signal conditioning and analog/digital interfacing. The molded, surface-mount SOIC package with gull-wing terminals (1.27mm pitch) ensures robust mechanical stability and ease of assembly in automated PCB processes.

SOMC1603820RGDC Features

• High Isolation: Designed with isolated resistors (ISOL) for minimal crosstalk in multi-channel systems.
• Thick-Film Technology: Delivers stable resistance and low noise for precision applications.
• Wide Temperature Range: Operates reliably from 70°C to 150°C with derated power handling.
• Compact & Durable: 11.18mm × 7.62mm × 2.03mm molded SOIC package with gull-wing leads for secure SMD mounting.
• Automation-Friendly: 1.27mm terminal pitch and tube packaging streamline high-volume PCB assembly.
• Non-Automotive (PPAP No): Ideal for industrial, telecom, and instrumentation applications where automotive compliance is not required.

SOMC1603820RGDC Applications

This resistor network excels in:

• Signal Isolation Circuits: Ensures clean signal separation in data acquisition systems and sensor interfaces.
• Voltage Dividers & Bias Networks: Precision 820Ω resistors enable accurate voltage scaling in op-amp circuits and ADC/DAC peripherals.
