4606X-104-331/391 Description

The 4606X-104-331/391 from Bourns Inc. is an 8-resistor network array designed for precision termination and signal conditioning in electronic circuits. Part of the 4600X series, this through-hole-mounted component features a compact SIP (Single In-Line Package) form factor with dimensions of 0.598" L × 0.098" W (15.19mm × 2.49mm) and a seated height of 0.200" (5.08mm). It offers dual terminator functionality with resistances of 330Ω and 390Ω, each with a tight tolerance of ±2% and a temperature coefficient of ±100ppm/°C, ensuring stable performance across varying thermal conditions.

4606X-104-331/391 Features

• High-Density Integration: Combines 8 resistors in a 6-pin SIP package, saving board space.
• Robust Power Handling: 200mW per element for reliable operation in demanding circuits.
• Stable Performance: Low ±100ppm/°C temperature coefficient minimizes resistance drift.
• Dual-Terminator Design: Ideal for impedance matching and signal integrity in bus lines.
• REACH Compliance: Unaffected by REACH restrictions, ensuring long-term availability.
• Obsolete Status: Suitable for legacy systems but may require alternative sourcing for new designs.
