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

Category: Electronics, Resistors, State Of The Art Inc

Overview

The PROTECTIVE 50505 Thin Film Chip Resistor manufactured by State of the Art, Inc. is a high-precision resistor with wraparound terminations on a standard-grade 99.6% alumina substrate. It is designed for scenarios demanding tight tolerance and stable performance in various environmental conditions.

Performance Characteristics

The resistor offers a resistance range from 5.60 ohms to 470K ohms, with tolerances available from 0.1% to 5%. The Temperature Coefficient of Resistance (TCR) varies depending on the specified tolerance and includes options of ±25, ±50, and ±100 ppm. For 0.1% tolerance, the minimum resistance range starts at 100 ohms, but with ±0.05% precision upon request. The maximum power dissipation is rated at 125 mW, and the resistor can withstand a maximum voltage of 40 Volts. Thermal resistance is measured at 38.8°C/W.

Environmental Performance

Environmental resilience includes stability against thermal shock, low temperature operation, and short-time overload, with typical resistance changes being within ±0.02% for most tests. High temperature exposure and moisture resistance are within ±0.03%. Life testing demonstrates resistance change over time, directly correlated with power derating and ambient temperature.

Part Numbering System

Part numbers for the chip resistors are composed of a series of identifiers indicating packaging code, termination finish, temperature characteristic, tolerance, resistance value, product designation, termination type, size code, and grade.

Packaging options include Tape/Reel (TR) and Waffle Carrier, with default packaging in bulk.
Termination finishes are denoted by ‘B’ for tin over a nickel barrier or ‘W’ for gold.
Temperature characteristics (TCR) and tolerances are represented by specific letters, correlating with a series of ppm values and percentage tolerances respectively.
Resistance values are coded using three or four digits, where the final digit indicates the multiplier for zeros, and a letter is used to denote decimal placement in fractional ohms.
Product designation ‘A’ specifies thin film on alumina, while termination type ‘C’ is for wraparound.
Size codes ‘S’ and ‘H’ differentiate between Standard Production and High Reliability.

Mechanical Specifications

The datasheet provides detailed mechanical dimensions of the resistors, including length, width, thickness, and termination sizes, with dimensions listed in both inches and millimeters. Minimum recommended motherboard land sizes are provided to ensure proper mounting.
