SASSSATION 3 0505 Thick Film Chip Resistor Datasheet

Category: Electronics, Resistors, State Of The Art Inc

Overview

The datasheet provides detailed information about the State of the Art, Inc. SASSSATION 3 0505 Thick Film Chip Resistor, which is categorized as a standard grade resistor with wraparound terminations crafted from 96% alumina. It outlines performance characteristics, environmental performance, power derating, part numbering, packaging options, temperature characteristics, tolerance, resistance value, termination finish, product designation, and mechanical specifications.

Performance Characteristics

Resistance Range: The resistors have a broad resistance range from 10 ohms to 4 megaohms.
Tolerances: Available tolerances are 1%, 2%, 5%, and 10%.
TCR (Temperature Coefficient of Resistance): Values specified as ±100 ppm, ±200 ppm, and ±300 ppm.
Thermal Resistance: Outlined as 45.5°C/W.
Maximum Power: Rated at 125 milliwatts.
Maximum Voltage: The maximum voltage rating is 40 volts.

Environmental Performance

Environmental tests display changes in resistance based on various stressors such as thermal shock, low and high temperature operation, short-time overload, exposure to bonding substances, moisture resistance, and a life test. The typical resistance change from these tests generally does not exceed ±0.05%.

Part Numbering and Packaging

The part numbering system details the various configurations of the chip resistors, including product designation (P for thick film on alumina; U for untrimmed alumina), temperature characteristic, tolerance, resistance value (using four digits for 1% tolerance and lower, and three digits for higher tolerances), and termination finish which has multiple options such as tin-lead over nickel or gold over nickel for solderability, or epoxy bondable finishes compliant with RoHS. Packaging codes indicate whether the resistors come in tape and reel (TR) or waffle carrier, with the default being bulk packaging.

Power Derating

The datasheet includes a chart that illustrates power derating across a range of ambient temperatures, demonstrating how the power dissipation capacity of the resistor changes with temperature.

Mechanical Specifications

Exact mechanical measurements of the chip resistors are provided in both inches and millimeters, as well as the minimum recommended pad sizes for mounting.
