4308H-102-101

4308H-102-101 Description

The 4308H-102-101 from Bourns Inc. is a high-performance 4-resistor network housed in an 8-pin SIP (Single In-line Package) configuration. Designed for precision applications, it features a 100Ω resistance per element with a tight ±2% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across varying environmental conditions. The device operates at 500mW power per element and is constructed with isolated circuit topology, minimizing crosstalk between resistors. Its compact 0.784" x 0.085" (19.91mm x 2.16mm) footprint and 0.350" (8.89mm) height make it suitable for space-constrained designs. Packaged in a tube, it is REACH compliant and classified under EAR99 for export control.

4308H-102-101 Features

• 4 isolated resistors in a single SIP package, reducing board space and assembly complexity.
• Low resistor-ratio drift (50ppm/°C), critical for precision voltage division and signal conditioning.
• 500mW power handling per resistor, supporting higher current applications than typical thin-film arrays.
• Through-hole mounting for robust mechanical stability in harsh environments.
• Wide operating temperature range with ±100ppm/°C TCR, ideal for industrial and automotive applications.
• Not MSL-rated (Moisture Sensitivity Level), eliminating baking requirements before assembly.

4308H-102-101 Applications

This resistor network excels in analog signal processing, voltage dividers, and feedback circuits where precision and stability are paramount. Its isolated design minimizes interference, making it suitable for:

• Industrial control systems (PLC I/O modules, sensor interfaces).
• Automotive electronics (ECUs, infotainment systems).
• Test and measurement equipment (calibration circuits, reference networks).
• Power supply feedback loops requiring tight tolerance and low drift.
