4608X-101-390 Description

The 4608X-101-390 from Bourns Inc. is a 7-resistor bussed network housed in an 8-pin SIP (Single In-line Package) configuration, designed for through-hole mounting. This obsolete but REACH-unaffected component offers a 39Ω resistance per element with a tight ±1Ω tolerance, ensuring precision in circuit design. Its ±250ppm/°C temperature coefficient provides stable performance across varying thermal conditions. The compact 0.798" x 0.098" (20.27mm x 2.49mm) footprint and 5.08mm seated height make it suitable for space-constrained applications. Rated at 200mW power per element, it balances power handling and miniaturization.

4608X-101-390 Features

• Bussed Circuit Topology: Simplifies PCB layout by connecting resistors in a common configuration.
• High Precision: ±1Ω tolerance and low TCR (±250ppm/°C) ensure reliable performance.
• Robust Construction: Through-hole design enhances mechanical durability.
• Compact SIP Package: Ideal for high-density boards.
• Non-MSIL (Not Applicable): Eliminates moisture sensitivity concerns during storage.
• Obsolete but REACH-Compliant: Safe for legacy designs without regulatory restrictions.

4608X-101-390 Applications

This resistor network excels in:

• Analog Signal Conditioning: Voltage dividers, pull-up/pull-down networks.
• Legacy Industrial Controls: PLCs, instrumentation, and test equipment.
• Power Management Circuits: Current limiting and load sharing in low-power systems.
• Consumer Electronics: Audio equipment, power supplies, and display drivers.
  Its bussed design is particularly advantageous in multi-channel systems requiring uniform resistance values.

Conclusion of 4608X-101-390

The 4608X-101-390 combines precision, compactness, and reliability, making it a pragmatic choice for legacy or maintenance designs. While obsolete, its REACH compliance and stable performance ensure continued usability in industrial and consumer applications.
