4606X-101-680

4606X-101-680 Description

The 4606X-101-680 is a 5-resistor bussed network from Bourns Inc.'s 4600X series, designed for through-hole mounting in compact electronic assemblies. With a 68Ω resistance per element and a tight ±2% tolerance, this array ensures reliable performance in precision circuits. Its ±100ppm/°C temperature coefficient enhances stability across varying thermal conditions, while the 200mW power rating per resistor balances efficiency and durability. The 6-pin SIP package (15.19mm x 2.49mm) and 5.08mm seated height make it suitable for space-constrained applications. Though marked Obsolete, it remains REACH compliant and MSL-exempt, ideal for legacy designs.

4606X-101-680 Features

• Bussed Circuit Topology: Simplifies PCB layout by connecting resistors in a common configuration.
• High Power Handling: 200mW per resistor outperforms many low-power arrays.
• Stable Performance: ±100ppm/°C TCR minimizes resistance drift in temperature-sensitive environments.
• Compact SIP Package: 0.598" x 0.098" footprint saves board space versus discrete resistors.
• Robust Construction: Through-hole design ensures mechanical durability in harsh conditions.

4606X-101-680 Applications

• Legacy Industrial Controls: Replacing discrete resistors in older automation systems.
• Power Supply Circuits: Voltage division and current limiting in linear regulators.
• Test & Measurement Equipment: Precision signal conditioning due to low tolerance.
• Consumer Electronics: Audio amplifiers and display drivers requiring stable resistance.
• Automotive Electronics: Non-critical circuits where bussed networks reduce part count.

Conclusion of 4606X-101-680

The 4606X-101-680 offers a cost-effective, space-saving solution for designs requiring multiple 68Ω resistors with moderate precision. Its bussed architecture, thermal stability, and through-hole reliability make it a pragmatic choice for legacy upgrades or repairs. While obsolete, its REACH compliance and MSL-free status ensure continued usability in niche applications. Engineers should evaluate alternatives for new designs but can leverage this array for its proven performance in existing systems.
