GS4A028201BBT Description

The GS4A028201BBT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. Housed in an 8-pin narrow SOIC package, it features four isolated thin-film resistors, each with a resistance value of 8.2KΩ 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 reliability in harsh environments. Its ±50ppm/°C temperature coefficient and 0.1W power rating per resistor (0.4W total) make it suitable for precision circuits requiring stable performance.

GS4A028201BBT Features

• High Precision: ±0.1% absolute tolerance and ±0.1% ratio tolerance for critical analog applications.
• Robust Construction: Ceramic SOIC package with gull-wing terminals for surface-mount (SMD) reliability.
• Isolated Resistors: Four independent 8.2KΩ resistors, ideal for isolation or differential signaling.
• Wide Voltage Rating: Supports up to 100V, suitable for industrial and automotive-grade designs (though not PPAP/automotive-certified).
• Stable Performance: ±50ppm/°C TCR ensures minimal resistance drift across temperature fluctuations.
• Compact Dimensions: 4.9mm (L) × 5.99mm (D) × 1.45mm (H) with tight tolerances (±0.1mm L/H, ±0.2mm D).

GS4A028201BBT Applications

• Precision Analog Circuits: Voltage dividers, feedback networks, and sensor conditioning.
• Industrial Electronics: PLCs, instrumentation, and test equipment requiring stable resistance values.
• Communication Systems: Isolated signal paths in data acquisition or telecommunication hardware.
• Medical Devices: Low-drift circuits where accuracy is critical (note: non-RoHS compliance may restrict use in some regions).

Conclusion of GS4A028201BBT

The GS4A028201BBT excels in applications demanding tight tolerance, low TCR, and high voltage handling. Its ceramic SOIC package offers durability, while the isolated thin-film resistors provide design flexibility.
