Token Electronics has introduced a new line of anti-corrosive precision chip resistors that eliminates moisture

concerns associated with typical Nickel Chromium precision resistors. The PR Series is an ideal low-cost

alternative for expensive and hard-to-find tantalum nitride chip resistors.

A proprietary passivation layer is introduced between the nichrome resistive element with a superior alumina

substrate and the epoxy overcoat to ensure stable performance and long life in the harshest and wettest

environments.

In MIL-STD-202F method moisture testing, the PR Series

demonstrated excellent stability over time and no significant

shift in resistance after the 1000 hour life test. Applications require

operation in humid or high moisture environments or have

experienced corrosion problems with standard Nichrome thin film

resistors. For those applications, long term extended humidity testing

is essential before a part can be considered for usage on a design.

Designated the PR Series, it is available in industry standard 0402, 0603, 0805, 1206, 2010, to 2512 sizes and

has a resistance range from 10 Ω to 1M Ω, with tolerances tight to ± 0.10% and TCRs as low as 25ppm/°C. The

PR Series has an operating temperature range of -55°C to +155°C. The PR chip also offers outstanding electrical

stability and environmental stability performance that would be expected from a precision resistor.

The standard packaging is tape and reel in 4Kpc, 5Kpc, and 10Kpc quantities depending on part size. Most

sizes and resistance values are also offered in stock, making them an outstanding choice to support quick turn

shortages. Pricing varies with size, tolerance, and TCR and ranges in reel quantities.

The chip PR series is lead-free and RoHS compliant. Detailed specifications, both mechanical and electrical,

please contact our sales representative for more information.
