GS8A021872BAT

GS8A021872BAT Description

The GS8A021872BAT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. Housed in a 16-pin narrow SOIC package, it features 8 isolated thin-film resistors, each with a resistance value of 18.7KΩ and an absolute tolerance of ±0.1%. The device operates over a wide temperature range of -55°C to +125°C, with a derated power range of 70°C to 125°C, ensuring stability in harsh environments. Its ±50ppm/°C temperature coefficient and 0.1W power rating per resistor (0.8W total) make it suitable for precision analog and digital circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the ceramic case enhances thermal and mechanical durability.

GS8A021872BAT Features

• High Precision: ±0.1% absolute tolerance and ±0.05% ratio tolerance for critical signal conditioning.
• Robust Construction: Ceramic SOIC package with 100V maximum voltage rating and thin-film technology for low noise.
• Thermal Stability: ±50ppm/°C TCR ensures minimal drift across -55°C to +125°C.
• Compact Design: 9.91mm × 5.99mm × 1.45mm dimensions with tight tolerances (±0.1mm height/length, ±0.2mm depth).
• Isolated Resistors: 8 independent elements prevent crosstalk in multi-channel systems.
• Industrial Compliance: EAR99 ECCN and non-RoHS status (note for restricted applications).

GS8A021872BAT Applications

• Precision Instrumentation: Voltage dividers, feedback networks in ADCs/DACs.
• Automotive Electronics: Sensor signal conditioning (though not PPAP/AEC-Q200 qualified).
• Telecom Infrastructure: Impedance matching in high-frequency circuits.
• Medical Devices: Low-drift circuits where accuracy is critical.
• Industrial Controls: Isolated signal paths in PLCs and motor drives.

Conclusion of GS8A021872BAT

The GS8A021872BAT excels in applications requiring high precision, thermal resilience, and compact integration. Its ceramic construction, tight tolerances, and isolated design distinguish it from polymer-based networks, making it ideal for mission-critical analog systems. While not automotive-grade, its performance suits industrial, medical, and telecom markets where reliability and accuracy are paramount. Engineers should verify RoHS compliance for regulated use cases.
