Surface Mount Resistors (PR)

Anti-corrosive thin film resistor of moisture-proof is ideal for high humidity precision applications.

DeMint Electronics has introduced a new line of SMD Anti-Corrosive Precision 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) SMD resistor, 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, download complete PDF specification (420KB) Anti-Corrosive Thin Film Precision Chip Resistors. Contact our sales representative for more information.
