Category: Electronics, Resistors, State Of The Art Inc

Overview

The State of the Art, Inc. datasheet describes the 5 0502 Thick Film Chip Resistor, highlighting its standard grade suitable for surface mount technology with a solderable glass passivation design.

Key Features and Performance

Features of the 5 0502 thick film chip resistor include tight tolerances down to 0.5%, a Temperature Coefficient of Resistance (TCR) up to ±100 ppm, and an operating temperature ranging from -55°C to +150°C. It is constructed using materials and processes equivalent to those in MIL-PRF-55342 “S” level chips. The resistors come with pretinned nickel barrier terminations that are reliable for various soldering methods, including solder reflow, vapor phase, and wave solder attachment.

The datasheet lists performance characteristics such as a resistance range starting from 10 Ohms, tolerances (0.5%, 1%, 2%, 5%, 10%), a maximum power rating of 21.6 milliwatts, and a voltage rating up to 40 Volts. Additionally, various environmental performance factors are specified, covering thermal shock, low and high-temperature operation, overload capacity, bonding exposure, moisture and life resistance.

Mechanical and Electrical Specifications

In terms of mechanical dimensions, the 5 0502 chip resistors’ size is 0.050 x 0.025 inches, with a weight of approximately 0.00158 grams. Solderability is ensured by a coating compatible with multiple solder types and is tested in accordance with Mil-Std-202 method 208.

Electrical specifications include TCR options spanning from ±100 ppm to ±300 ppm and a variety of tolerance classes from 0.5% to 20%. The resistor values are expressed in three to four significant digits with the letter “R” representing the decimal in fractional ohmic values.

Part Numbering System

A detailed part numbering system is provided to specify the resistor’s attributes, including size, tolerance, TCR, and resistance value.

Packaging and Options

Packaging solutions offered include bulk packaging, waffle pack, and tape & reel, with maximized quantities of respectively 5000, 400, and 5000 units. Options for customization include high-reliability testing, epoxy or wire bondable terminations, part marking, and untrimmed resistors.
