4606X-104-221/331 Description

The 4606X-104-221/331 by Bourns Inc. is an 8-resistor network array configured in a 6-pin SIP (Single In-line Package) through-hole mounting design. This dual terminator network features two distinct resistance values: 220Ω and 330Ω, each with a tight tolerance of ±2% and a low temperature coefficient of ±100ppm/°C, ensuring stable performance across varying environmental conditions. The compact dimensions (0.598" x 0.098" / 15.19mm x 2.49mm) and low-profile height (0.200" / 5.08mm) make it suitable for space-constrained PCB layouts. Rated at 200mW per resistor, this obsolete but REACH-unaffected component remains a reliable choice for legacy designs requiring precision resistor networks.

4606X-104-221/331 Features

• Dual Resistance Values: Combines 220Ω and 330Ω resistors in a single package, simplifying circuit design.
• High Precision: ±2% tolerance and ±100ppm/°C temperature coefficient ensure consistent performance.
• Robust Construction: Through-hole SIP package with bulk packaging for durability and ease of handling.
• Space-Efficient: Compact footprint ideal for high-density PCBs.
• Legacy Compliance: EAR99 and REACH-unaffected status, suitable for export-controlled applications.

4606X-104-221/331 Applications

This resistor network excels in termination circuits, pull-up/pull-down networks, and voltage divider applications, particularly in legacy industrial and communication equipment. Its dual-resistance configuration is optimal for impedance matching in signal lines and biasing in analog/digital hybrid circuits. Common use cases include:

• Telecom infrastructure: Line termination in legacy systems.
• Industrial control systems: Precision voltage division for sensors.
• Test and measurement equipment: Stable reference networks.

Conclusion of 4606X-104-221/331

While marked obsolete, the 4606X-104-221/331 remains a high-performance solution for applications demanding dual-resistance precision, compactness, and through-hole reliability. Its low thermal drift and robust SIP package make it a preferred choice for legacy upgrades or repairs where modern SMD alternatives are impractical. Engineers valuing long-term stability and proven performance in harsh environments will find this Bourns network array a dependable option.
