4308M-102-203 Description

The 4308M-102-203 from Bourns Inc. is a high-performance 4-resistor network designed for precision applications in electronic circuits. Part of the 4300M series, this through-hole-mounted array features 20kΩ resistance per element with a tight ±2% tolerance, ensuring reliable signal conditioning and voltage division. Its isolated circuit type allows independent resistor operation, while the ±100ppm/°C temperature coefficient and 50ppm/°C resistor-ratio drift guarantee stability across varying environmental conditions. Encased in an 8-pin SIP package with dimensions of 0.784" x 0.085" (19.91mm x 2.16mm), it offers a compact footprint for space-constrained designs.

4308M-102-203 Features

• 4 isolated resistors in a single package, reducing component count and PCB space.
• 400mW power rating per element, suitable for moderate power applications.
• Low TCR (±100ppm/°C) and 50ppm/°C ratio drift, ensuring minimal resistance variation with temperature fluctuations.
• Through-hole mounting for robust mechanical stability in harsh environments.
• REACH compliant and EAR99/ECCN classified, facilitating global supply chain integration.
• Non-MSAL (Moisture Sensitivity Level Not Applicable), simplifying storage and handling.

4308M-102-203 Applications

Ideal for precision analog circuits, this resistor network excels in:

• Voltage dividers and gain setting in operational amplifier circuits.
• Sensor signal conditioning (e.g., bridge networks in strain gauges or RTDs).
• Industrial control systems requiring stable resistance ratios over temperature.
• Medical instrumentation where consistent performance is critical.
• Automotive electronics due to its durability and tolerance to environmental stress.

Conclusion of 4308M-102-203

The 4308M-102-203 stands out for its combination of precision, compactness, and reliability, making it a superior choice over discrete resistors in space-sensitive designs.
