GS4A011870FT

GS4A011870FT Description

The GS4A011870FT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. Housed in an 8-pin narrow SOIC package, it features four isolated thin-film resistors, each with a resistance value of 187Ω and a tight ±1% tolerance. The device operates over a wide temperature range of -70°C to +125°C, with a derated power range of 70°C to 125°C, ensuring reliability in demanding environments. Its ±100ppm/°C temperature coefficient and 100V maximum voltage rating make it suitable for stable, low-drift circuits. The SOIC-C series construction offers robust ceramic case durability, while the gull-wing termination enables secure surface-mount (SMD) installation.

GS4A011870FT Features

• Isolated Resistors: Four independent 187Ω resistors with 1% absolute tolerance for precise signal conditioning.
• High-Temperature Stability: ±100ppm/°C TCR and 125°C max operating temp ensure minimal drift in harsh conditions.
• Robust Construction: Ceramic SOIC package with rectangular shape (4.9mm x 5.99mm x 1.45mm) and ±0.1mm height tolerance for mechanical resilience.
• Power Efficiency: 0.1W per resistor (0.4W total) at 70°C, derated linearly to 125°C.
• Industry Compliance: HTS 8533.21.00.20, ECCN EAR99, though non-RoHS and non-automotive (PPAP No).

GS4A011870FT Applications

• Signal Isolation: Ideal for ADC/DAC reference dividers and sensor interface circuits requiring isolated impedance matching.
• Industrial Electronics: Suited for PLC modules, power supplies, and test equipment due to high voltage tolerance (100V) and thermal stability.
• Medical Devices: Reliable performance in patient monitoring systems where precision and low drift are critical.
• Aerospace & Defense: Ceramic packaging and wide temp range make it viable for avionics and ruggedized communication systems.

Conclusion of GS4A011870FT

The GS4A011870FT stands out for its precision, isolation, and ceramic-based durability, making it a superior choice for applications demanding stable resistance under thermal stress. While not RoHS-compliant, its thin-film technology and SOIC-C package offer a balance of performance and compactness, particularly in industrial, medical, and high-reliability systems. Engineers should consider this model for designs requiring tight-tolerance, multi-resistor networks with proven thermal resilience.
