(PR) Anti-Corrosive Series of Moisture-Proof
Chip Resistors for High Humidity Precision Applications
Preview
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.
