4308R-102-680LF Description

The 4308R-102-680LF from Bourns Inc. is a high-performance 4-resistor isolated network designed for precision applications in electronic circuits. This through-hole-mounted device features a compact 8-pin SIP (Single In-Line Package) with a 68Ω resistance per element, offering a tight ±2% tolerance and a low ±100ppm/°C temperature coefficient. Its 300mW power rating per resistor ensures reliable operation in demanding environments, while the 50ppm/°C resistor-ratio drift enhances stability in differential signal processing. The ROHS3 compliance and REACH Affected status align with modern environmental standards, making it suitable for global markets.

4308R-102-680LF Features

• Isolated Circuit Design: Ensures independent resistor performance, reducing crosstalk in sensitive analog/digital systems.
• High Power Handling: 300mW per element supports robust operation in power-sensitive applications.
• Low TCR & Tight Tolerance: ±100ppm/°C and ±2% tolerance ensure precision in temperature-variable environments.
• Compact SIP Package: Measures 19.91mm x 2.16mm (0.784" x 0.085") with a 4.95mm (0.195") height, ideal for space-constrained PCBs.
• Industrial-Grade Reliability: Not MSL-rated (Moisture Sensitivity Level) simplifies storage and handling.

4308R-102-680LF Applications

This resistor network excels in:

• Voltage Division & Signal Conditioning: Precision attenuation in sensor interfaces (e.g., industrial automation).
• Differential Amplifiers: Stable performance due to low ratio drift (50ppm/°C).
• Legacy & High-Reliability Systems: Through-hole design suits automotive, aerospace, and military electronics.
• Test & Measurement Equipment: Low TCR minimizes drift in calibration circuits.
