GS4B023920BBT Description

The GS4B023920BBT from TT Electronics/IRC is a high-precision 7-resistor thin film network designed for demanding circuit applications. Encased in a ceramic SOIC-8 package, it offers a 392Ω resistance per element with an ultra-tight 0.1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a -70°C to +125°C operating range. Rated for 0.4W total power dissipation (0.05W per resistor) and 100V maximum voltage, this surface-mount (SMD) network features gull-wing terminations with a 1.27mm pitch for reliable PCB integration. Its ceramic substrate enhances thermal performance, while the non-RoHS-compliant construction suits legacy or specialized designs.

GS4B023920BBT Features

• Precision Thin Film Technology: Delivers 0.1% tolerance and ±50ppm/°C TCR for critical analog/digital circuits.
• Robust Ceramic Package: SOIC-8 case with 4.9mm × 5.99mm × 1.45mm dimensions (±0.1mm tolerance) ensures durability and heat dissipation.
• BUS Circuit Design: Ideal for voltage division, pull-up/down networks, and impedance matching in multi-channel systems.
• High-Temperature Operation: Stable performance up to 125°C, derated for extended reliability.
