4608X-102-181 Description

The 4608X-102-181 is a 4-resistor network from Bourns Inc.'s 4600X series, designed for through-hole mounting applications. This obsolete but reliable component features isolated circuit topology, with each of its four 180Ω resistors offering a tight ±2% tolerance and a ±100ppm/°C temperature coefficient. Encased in an 8-pin SIP package, it measures 0.798" x 0.098" (20.27mm x 2.49mm) with a seated height of 0.200" (5.08mm). Rated for 300mW power per element, it is REACH unaffected and carries an ECCN EAR99 designation, making it suitable for legacy designs requiring stable, precision resistance networks.

4608X-102-181 Features

• High Precision: ±2% tolerance ensures consistent performance in critical circuits.
• Robust Construction: Through-hole design with 8-pin SIP package for mechanical durability.
• Stable Performance: ±100ppm/°C temperature coefficient minimizes resistance drift.
• Isolated Circuitry: Independent resistors reduce crosstalk in multi-channel applications.
• Legacy Compliance: REACH unaffected and MSL Not Applicable, ideal for long-lifecycle systems.
• Compact Footprint: Space-efficient 20.27mm length suits densely populated PCBs.

4608X-102-181 Applications

• Industrial Controls: Precision voltage division in PLCs and sensor interfaces.
• Legacy Electronics: Repair or maintenance of older equipment requiring 180Ω isolated arrays.
• Test & Measurement: Calibration circuits due to low tolerance and thermal stability.
• Power Supplies: Current-limiting or feedback networks in linear regulators.
• Automotive Systems: Redundant circuits where isolation and reliability are critical (though design verification is advised for modern applications).

Conclusion of 4608X-102-181

While obsolete, the 4608X-102-181 remains a viable choice for engineers maintaining or designing systems that demand high-precision, isolated resistor networks. Its low tolerance, stable thermal performance, and through-hole reliability make it particularly suited for industrial, automotive, and test equipment where replacement components must match legacy specifications. For new designs, Bourns' modern equivalents should be evaluated, but this model excels in backward-compatibility scenarios.
