State of the Art, Inc. ENCAPSULANT PRECISION 5 0505 Thin Film Chip Resistor

Category: Electronics, Resistors, State Of The Art Inc

Overview

The datasheet presents the Precision 5 0505 Thin Film Chip Resistor from State of the Art, Inc., which features a standard-grade wraparound termination and is constructed on a 99.6% alumina substrate. The resistor is designed for environments that require high precision and stability.

Performance Characteristics

The resistance range for these resistors is 5.60Ω to 470KΩ with available tolerances of 0.1%, 0.25%, 0.5%, 1%, 2%, and 5%. Temperature Coefficient of Resistance (TCR) offerings include 25ppm, 50ppm, and 100ppm. They have a maximum power dissipation of 125mW and a maximum working voltage of 40 volts. Typical current noise is specified as well as the power dissipation on different board materials, such as ceramit and fiber epoxy boards.

Environmental Performance

Environmental performance tests, which comply with MIL-PRF-55342 standards, include thermal shock, low temperature operation, short-time overload, resistance to bonding exposure, moisture resistance, high temperature exposure, and life tests. Changes in resistance as a result of these tests are minimal, generally within ±0.02% to ±0.03%.

Power Derating and Typical Life Test Performance

The datasheet includes a chart for power derating over ambient temperature, indicating how power dissipation capability decreases with an increase in ambient temperature. Typical life test performance is graphed, showing resistance change over time when subjected to continuous operation.

Part Numbering System

Part numbering is detailed to allow for correct identification of specific resistor features. These features include packaging code, termination finish, temperature characteristics (TCR), tolerance, resistance value, product designation, and termination type. The size and grade of the resistor are also specified, with standard grade options and the possibility of high reliability upon request.

The datasheet includes mechanical specifications such as resistor size in inches and millimeters, top and bottom terminal size, and approximate weight. It provides recommended mounting pads dimensions. All specifications are subject to change without notice.
