State of the Art, Inc. SASSSATION 3 0603 Thick Film Chip Resistor

Category: Electronics, Resistors, State Of The Art Inc

Overview

The SASSSATION 3 0603 is a thick film chip resistor fabricated on a 96% alumina substrate and offered by State of the Art, Inc. It is designed to provide reliable performance in a standard grade with wraparound terminations. This resistor is available in a resistance range from 10 ohms to 40 megohms, with tolerance options including 0.5%, 1%, 2%, 5%, and 10%.

Performance Characteristics

The product exhibits a Temperature Coefficient of Resistance (TCR) with variations such as +100 ppm, +200 ppm, and +300 ppm, depending on the selected temperature characteristic. It has a maximum power dissipation of 100 milliwatts and can withstand a maximum voltage of 45 volts. The thermal resistance is specified at 78.4°C/W, ensuring efficient heat dissipation during operation.

Environmental Performance

Environmental resilience tests show changes in resistance under various stress factors, including thermal shock, low-temperature operation, short-time overload, and exposure to moisture and bonding materials. Typically, resistance shifts are within 0.03% to 0.05% after these environmental exposures as per the MIL-PRF-55342 standard.

Power Derating and Life Test

Power derating is essential for ensuring the longevity of the resistor, with a chart illustrating the allowed power consumption according to ambient temperature. The product is subjected to a life test, signalling a limited resistance shift over time during continuous use, specifically over 2500 hours at 70% power derating.

Part Numbering and Packaging

The part numbering system is informative, denoting packaging code, temperature characteristic, tolerance, resistance value, termination finish, product designation, and termination type. Packaging options include tape/reel and waffle carrier, while terminations come in different finishes like tin over nickel, silver-bearing, gold, and gold over nickel, all accommodating soldering or epoxy bonding processes.

Mechanical Characteristics

The component’s physical dimensions are detailed in both inches and millimeters, inclusive of length, width, thickness, and terminal features. An approximate weight is also provided. Recommended mounting pad dimensions are given to aid in optimal circuit board design and ensure secure installation.
