VTF280SUF

VTF280SUF Description

The VTF280SUF from Vishay is a high-precision thin film resistor network designed for demanding applications requiring low noise, high stability, and tight tolerance. Configured as a 2-resistor network (9KΩ/1KΩ) with a 0.1% tolerance, it delivers exceptional accuracy in voltage division (VOLT/D) circuits. Encased in a conformal-coated SIP package, the device ensures reliability in harsh environments. With a ±10ppm/°C temperature coefficient, it maintains stable performance across a 0°C to 70°C operating range. The through-hole, 3-pin SIP design (8.13mm length, 2.54mm pitch) simplifies PCB integration, while its 0.5W (1/2W) total power rating (0.1W per resistor) suits medium-power applications.

VTF280SUF Features

• Precision Performance: 0.1% tolerance and ±10ppm/°C TCR ensure minimal drift in critical circuits.
• Robust Construction: Conformal coating enhances moisture and contaminant resistance.
• Optimized Layout: Single-line SIP package (2.54mm pitch) saves board space vs. discrete resistors.
• High Stability/Low Noise: Ideal for sensitive analog signal chains.
• Wide Voltage Range: Supports up to 100V, suitable for industrial and instrumentation use.
• Compliance: EU RoHS compliant and EAR99 classified for global deployment.

VTF280SUF Applications

• Voltage Dividers: Precision attenuation in ADC/DAC reference circuits and sensor interfaces.
• Medical/Test Equipment: Stable performance in patient monitoring or calibration systems.
• Industrial Controls: Reliable operation in PLC modules and power supply feedback networks.
• Automotive (Non-Automotive Rated): Prototyping or benign-environment automotive electronics.
• Aerospace & Defense: Conformal coating mitigates environmental stress in non-critical subsystems.

Conclusion of VTF280SUF

The VTF280SUF excels in applications demanding precision, stability, and compactness. Its thin film technology, conformal protection, and SIP packaging offer a superior alternative to discrete resistors or less stable networks. While not PPAP or automotive-qualified, it is a cost-effective solution for industrial, medical, and instrumentation designs where low noise and high accuracy are paramount. Vishay’s reputation for quality ensures reliability in mission-critical systems.
