4308R-104-103/203L

4308R-104-103/203L Description

The 4308R-104-103/203L from Bourns Inc. is a high-performance 12-resistor network designed for precision applications in electronic circuits. Housed in an 8-pin SIP (Single In-Line Package), this through-hole-mounted component features dual terminator functionality with resistances of 10kΩ and 20kΩ, offering a ±2% tolerance and a ±100ppm/°C temperature coefficient. Its compact dimensions (0.784" x 0.085") and 200mW power rating per element make it suitable for space-constrained designs. The device is RoHS3 compliant and operates reliably across industrial temperature ranges, with a resistor-ratio drift of 50ppm/°C for stable performance.

4308R-104-103/203L Features

• Dual terminator circuit: Optimized for impedance matching and signal integrity in high-speed applications.
• Low TCR (±100ppm/°C): Ensures minimal resistance variation under thermal stress.
• High power handling (200mW per resistor): Supports demanding loads without derating.
• Precision ratio drift (50ppm/°C): Critical for differential signaling and analog systems.
• Industrial-grade reliability: REACH and RoHS3 compliant, with MSL: Not Applicable for robust handling.
• Space-saving SIP package: Ideal for dense PCB layouts while maintaining ease of assembly.
