4820P-3-331/680

4820P-3-331/680 Description

The 4820P-3-331/680 from Bourns Inc. is a high-performance 36-resistor network designed for precision applications in surface-mount PCB assemblies. Housed in a compact 20-pin SOIC package (13.72mm x 5.59mm), it features dual terminator circuitry with resistances of 68Ω and 330Ω, offering ±2Ω absolute tolerance or ±2% relative tolerance per element. With a ±100ppm/°C temperature coefficient and 80mW power rating per resistor, this network ensures stable performance across industrial temperature ranges. Compliant with REACH and ECCN EAR99, it is packaged in Tape & Reel (TR) for automated assembly efficiency.

4820P-3-331/680 Features

• High-Density Integration: 36 resistors in a space-saving 0.094" (2.40mm) profile, ideal for densely populated PCBs.
• Dual-Terminator Design: Optimized for impedance matching in high-speed signal lines (e.g., USB, LVDS).
• Robust Performance: MSL 1 (Unlimited) moisture sensitivity ensures reliability in humid environments.
• Low TCR: ±100ppm/°C minimizes resistance drift under thermal stress.
• Automation-Ready: Tape-and-reel packaging supports high-volume SMT processes.

4820P-3-331/680 Applications

• Termination Networks: Critical for PCIe, DDR memory buses, and other high-speed digital interfaces.
• Signal Conditioning: Used in ADC/DAC circuits, sensor arrays, and precision voltage dividers.
• Industrial Electronics: Suitable for PLC I/O modules, motor drives, and power supply feedback loops.
• Consumer Devices: Embedded in set-top boxes, networking equipment, and display controllers.

Conclusion of 4820P-3-331/680

The 4820P-3-331/680 stands out for its combination of density, precision, and thermal stability, making it a superior choice over discrete resistors in space-constrained designs.
