4610X-101-121

4610X-101-121 Description

The 4610X-101-121 is a 9-resistor bussed network from Bourns Inc.'s 4600X series, designed for through-hole mounting in compact electronic assemblies. This obsolete yet reliable component features a 120Ω resistance per element with a tight ±2% tolerance, ensuring consistent performance in precision circuits. Its ±100ppm/°C temperature coefficient provides stable operation across varying thermal conditions, while the 200mW power rating per resistor balances power handling and space efficiency. Encased in a 10-pin SIP package with dimensions of 0.998" x 0.098" (25.35mm x 2.49mm) and a 5.08mm height, it suits space-constrained designs. The REACH-unaffected and MSL-not-applicable status simplifies compliance and handling.

4610X-101-121 Features

• High-Density Integration: 9 resistors in a single SIP package reduce PCB footprint versus discrete components.
• Stable Performance: ±100ppm/°C TCR and ±2% tolerance ensure reliability in temperature-sensitive applications.
• Robust Construction: Through-hole design enhances mechanical durability for industrial environments.
• Simplified Bussing: Bussed circuit type streamlines connections in voltage-divider or pull-up/down networks.
• Compliance Ready: EAR99 ECCN and HTSUS 8533.21.0050 classifications facilitate global sourcing.

4610X-101-121 Applications

Ideal for legacy or maintenance-driven designs, this network excels in:

• Analog Signal Conditioning: Precision voltage division in sensor interfaces.
• Digital Pull-Up/Down Networks: Stabilizing logic levels in microcontrollers or communication buses.
• Power Supply Circuits: Current-limiting or bias networks in low-power DC/DC converters.
• Industrial Control Systems: Durable performance in PLCs or motor drives where through-hole reliability is critical.

Conclusion of 4610X-101-121

While marked obsolete, the 4610X-101-121 remains a viable choice for engineers seeking a cost-effective, space-saving resistor network with proven stability. Its bussed architecture, tight tolerance, and robust SIP package make it particularly suited for legacy upgrades or applications demanding repeatable performance. For new designs, Bourns' modern equivalents may offer enhanced features, but this model retains value in niche or long-lifecycle systems.
