GS4A0129R4GT

GS4A0129R4GT Description

The GS4A0129R4GT from TT Electronics/IRC is a high-performance 4-resistor network in an 8-pin narrow SOIC package, designed for precision applications requiring stable, isolated thin-film resistors. With a 29.4Ω resistance per element and a tight ±2% tolerance, this network ensures reliable signal conditioning and voltage division in compact circuits. The ceramic substrate and thin-film technology provide excellent thermal stability, with a ±100ppm/°C temperature coefficient, making it suitable for environments with fluctuating temperatures. Rated for 0.1W per resistor (0.4W total) and a maximum operating temperature of 125°C, it delivers consistent performance under moderate power loads. Its 100V maximum voltage rating and gull-wing termination facilitate secure surface-mount assembly in space-constrained designs.

GS4A0129R4GT Features

• Isolated Resistor Network: Four independent resistors in an SOIC package, ideal for isolation-critical designs.
• High Precision: ±2% absolute tolerance and ±100ppm/°C TCR ensure minimal drift in demanding conditions.
• Robust Construction: Ceramic case enhances durability and heat dissipation.
• Surface-Mount Ready: Gull-wing leads with 1.27mm pitch for reliable PCB mounting.
• Wide Temperature Range: Operates from 70°C to 125°C with derated power, suitable for industrial and automotive (non-PPAP) applications.
• Compact Footprint: 4.9mm (L) × 5.99mm (D) × 1.45mm (H) with tight tolerances (±0.1mm L/H, ±0.2mm D).

GS4A0129R4GT Applications

• Signal Conditioning: Precision voltage dividers in sensor interfaces and ADC circuits.
• Industrial Controls: Isolated feedback networks in power supplies and motor drivers.
• Test & Measurement Equipment: Stable reference resistors for calibration systems.
• Consumer Electronics: Space-efficient resistor arrays in compact PCBs.
• Telecom Infrastructure: Impedance matching in high-frequency modules (despite non-RoHS status).

Conclusion of GS4A0129R4GT

The GS4A0129R4GT excels in applications demanding precision, thermal stability, and compactness. Its ceramic thin-film design and isolated resistors offer superior performance over polymer-based networks, particularly in environments with thermal stress. While not RoHS-compliant, its high voltage rating and tight tolerances make it a preferred choice for industrial and instrumentation designs where reliability outweighs regulatory constraints. Engineers will value its balance of performance, size, and cost in critical circuits.
