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

Category: Electronics, Resistors, State Of The Art Inc

Overview

State of the Art, Inc. presents the SASSSATION 3 0603, a thick film chip resistor range with standard-grade performance for various applications. This datasheet gives detailed insight into the resistor’s characteristics, including resistance range, tolerances, temperature coefficient resistance (TCR), maximum power, and voltage ratings, as well as environmental test performances.

Electrical and Mechanical Characteristics

The resistors have a wide resistance range of 10 to 40 megohms (MQ) and tolerances of 0.5%, 1%, 2%, 5%, and 10%. Note, however, that the 0.5% tolerance option is of limited availability. The TCR for these resistors can be +100, +200, or +300 parts per million (ppm), with a thermal resistance of 78.4* C/W. These resistors can handle a maximum power of 100 milliwatts (mW) and are rated for a maximum voltage of 45 Volts.

Environmental Performance

The SASSSATION 3 0603 resistors demonstrate robust environmental performance with typical resistance change tests and criteria as per MIL-PRF-55342. The datasheet lists results from a series of tests, including Thermal Shock, Low Temperature Operation, Short-time Overload, Resistance to Bonding Exposure, Moisture Resistance, High-Temperature Exposure, and a Life Test. The life test features power derating curves showing how power handling capability decreases with rising ambient temperature, maintaining performance within the limit of 7% over 25000 hours.

Part Numbering System

The datasheet details a unique part numbering system that allows for easy identification of specifications for each resistor variant. Key aspects of this system include packaging code, temperature characteristic, tolerance, resistance value, termination finish, product designation (thickness), termination type (wraparound), size code, and production grade. The resistor values are conveyed clearly, using a combination of numbers and letters, with the “R” symbol indicating decimal placement for ohmic values.

Mechanical Specifications

The datasheet specifies the mechanical dimensions of the SASSSATION 3 0603 resistors in both inches and millimeters, including length, width, thickness, and approximate weight. Furthermore, it provides the minimum recommended mounting pad sizes to help with appropriate circuit board design and layout.
