4610X-101-203 Description

The 4610X-101-203 is a 9-resistor bussed network from Bourns Inc.'s 4600X series, designed for precision through-hole applications. This obsolete but REACH-compliant component features a 20kΩ resistance per element with a tight ±2% tolerance and a ±100ppm/°C temperature coefficient, ensuring stable performance across varying environmental conditions. Encased in a compact 10-pin SIP package (25.35mm x 2.49mm), it offers a 200mW power rating per resistor and a 5.08mm seated height, making it suitable for space-constrained designs. The non-MSLA (Moisture Sensitivity Level) bulk packaging simplifies handling and storage.

4610X-101-203 Features

• High-Density Integration: Combines 9 resistors in a single SIP package, reducing PCB footprint versus discrete components.
• Stable Performance: Low TCR (±100ppm/°C) and ±2% tolerance ensure reliability in precision circuits.
• Robust Construction: Through-hole mounting enhances mechanical durability for industrial environments.
• Simplified Design: Bussed circuit topology streamlines layout in voltage-divider or pull-up/down networks.
• Compliance: EAR99/ECCN and REACH Unaffected status facilitate global sourcing and integration.

4610X-101-203 Applications

Ideal for legacy or maintenance-critical systems, the 4610X-101-203 excels in:

• Analog Signal Conditioning: Precision voltage dividers in sensor interfaces.
• Digital Pull-Up/Down Networks: Stabilizing logic levels in microcontrollers or FPGAs.
• Industrial Control Systems: Durable resistor arrays for PLCs or motor drives.
• Test & Measurement Equipment: Calibration circuits requiring stable resistance values.
• Aerospace & Defense: Obsolete part replacements in long-lifecycle systems.

Conclusion of 4610X-101-203

While marked obsolete, the 4610X-101-203 remains a viable solution for applications demanding high-density, precision resistance with robust through-hole reliability. Its bussed architecture, low TCR, and compact form offer distinct advantages over discrete resistors in legacy or space-sensitive designs. Engineers sourcing this part should verify alternative availability or consider Bourns' active equivalents for new projects.
