4308R-102-680

4308R-102-680 Description

The 4308R-102-680 from Bourns Inc. is a high-performance 4-resistor network housed in an 8-pin SIP (Single In-line Package). Designed for precision applications, it features 68Ω resistance per element with a tight ±2% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across varying environmental conditions. The isolated circuit configuration allows independent resistor operation, making it ideal for complex analog or digital circuits. With a 300mW power rating per element and a compact 0.784" x 0.085" (19.91mm x 2.16mm) footprint, this through-hole-mounted array balances power handling and space efficiency. Its REACH-compliant and EAR99-classified status ensures global regulatory compliance.

4308R-102-680 Features

• 4 isolated resistors in an 8-pin SIP package for flexible circuit design.
• 68Ω resistance with ±2% tolerance for precision applications.
• Low ±100ppm/°C TCR and 50ppm/°C resistor-ratio drift for thermal stability.
• 300mW power dissipation per element for robust performance.
• Compact through-hole mounting (4.95mm max height) suits space-constrained PCBs.
• Tube packaging for secure handling and automated assembly.
• Not MSL-rated (Moisture Sensitivity Level), eliminating baking requirements.

4308R-102-680 Applications

This resistor network excels in:

• Voltage division and current limiting in analog signal chains.
• Pull-up/pull-down networks for digital logic circuits (e.g., microcontrollers).
• Sensor conditioning where stable resistance ratios are critical (e.g., bridge circuits).
• Industrial control systems requiring high reliability and thermal consistency.
• Automotive electronics (non-safety-critical) due to its robust construction.

Conclusion of 4308R-102-680

The 4308R-102-680 stands out for its precision, thermal stability, and compact design, making it a superior choice over generic resistor arrays. Its isolated configuration and high power handling cater to demanding applications in industrial, automotive, and consumer electronics. Bourns' reputation for quality ensures long-term reliability, while the non-MSL designation simplifies storage and assembly processes.
