OSOPTA1003AT1

OSOPTA1003AT1 Description

The OSOPTA1003AT1 from Vishay is a high-precision thin-film resistor network designed for demanding applications requiring tight tolerance and stable performance. This 20-pin SSOP (Shrink Small Outline Package) device integrates 10 isolated 100KΩ resistors with an exceptional ±0.1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring minimal drift across operating conditions. Rated for 0.4W total power dissipation (0.1W per resistor) and 100V maximum voltage, it operates reliably up to 125°C, making it suitable for industrial and instrumentation environments. The molded, gull-wing termination design enhances mechanical durability and facilitates surface-mount assembly, while the tape-and-reel packaging optimizes automated PCB production.

OSOPTA1003AT1 Features

• Precision Performance: Thin-film technology delivers 0.1% tolerance and ±25ppm/°C TCR for critical analog circuits.
• Robust Construction: Molded SSOP case with 1.73mm seated height and 6.02mm × 8.66mm footprint ensures space efficiency and durability.
• Isolated Resistors: 10 independent 100KΩ resistors (ISOL circuit designator) prevent crosstalk in signal conditioning.
• High-Temperature Operation: Rated for 125°C, ideal for harsh environments.
• Automation-Friendly: Gull-wing leads (1.47mm pitch) and tape-and-reel packaging streamline SMT processes.
• Compliance: EU RoHS compliant and EAR99 classified for global deployment.
