GS4B028200DDT

GS4B028200DDT Description

The GS4B028200DDT from TT Electronics/IRC is a high-precision 7-resistor thin film network in an 8-pin SOIC package, designed for surface-mount applications. With a 820Ω resistance per element, it offers a tight ±0.5% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a -70°C to +125°C operating range. The ceramic substrate enhances thermal stability, while the gull-wing termination facilitates reliable PCB mounting. Rated for 0.4W total power dissipation (0.05W per resistor) and 100V maximum voltage, this non-automotive, non-PPAP compliant component is ideal for precision analog and digital circuits.

GS4B028200DDT Features

• High Accuracy: ±0.5% tolerance and ±50ppm/°C TCR for precision applications.
• Robust Construction: Ceramic case and thin film technology ensure durability and long-term stability.
• Space-Efficient: Compact SOIC-8 package (4.9mm × 5.99mm × 1.45mm) with 1.27mm terminal pitch.
• Wide Operating Range: Derated power up to 125°C, suitable for industrial environments.
• Low Power Dissipation: 0.05W per resistor (0.4W total) balances performance and energy efficiency.
• Non-Compliant with EU RoHS: Note for applications exempt from RoHS restrictions.

GS4B028200DDT Applications

• Signal Conditioning: Precision voltage dividers in sensor interfaces.
• Analog Circuits: Feedback networks in op-amps and instrumentation amplifiers.
