MCR18 Resistors Thick film rectangular MCR18 (3216 size: 1 / 4W) !Features 1) Power rating of 1 / 4W 2) Highly reliable chip resistor Ruthenium oxide dielectric offers superior resistance to the elements. 3) Electrodes not corroded by soldering Thick film makes the electrodes very strong. 4) Leading the world in development and mass production. Since start of production in 1976 (first in the wold), this component has established a solid reputation as a general purpose chip resistor. 5) ROHM resistors have approved ISO9001 certification. Design and specifications are subject to change without notice. Carefully check the specification sheet before using or ordering it. !Ratings Item Conditions Specifications 0.25W (1 / 4W) Rated power Power must be derated according to the power derating curve in at 70°C Figure 1 when ambient temperature exceeds 70°C. 100 80 60 40 20 0 −55 0 70 100 155 AMBIENT TEMPERATURE (°C) Fig.1 Rated voltage The voltage rating is calculated by the following equation.

EXCELLENT SERVICE
With our strict fundamentals and high expectations, we were surprised when we came across GID Industrial and their competitive pricing. When we approached them with our issue, they were incredibly confident in being able to provide us with a seamless solution at the best price for us. GID Industrial quickly understood our needs and provided us with excellent service, as well as fully tested product to ensure what we received would be the right fit for our company.
Fuji
HARD TO FIND A BETTER PROVIDER
Our company provides services to aid in the manufacture of technological products, such as semiconductors and flat panel displays, and often searching for distributors of obsolete product we require can waste time and money. Finding GID Industrial proved to be a great asset to our company, with cost effective solutions and superior knowledge on all of their materials, it’d be hard to find a better provider of obsolete or hard to find products.
Applied Materials
CONSISTENTLY DELIVERS QUALITY SOLUTIONS
Over the years, the equipment used in our company becomes discontinued, but they’re still of great use to us and our customers. Once these products are no longer available through the manufacturer, finding a reliable, quick supplier is a necessity, and luckily for us, GID Industrial has provided the most trustworthy, quality solutions to our obsolete component needs.

TERRIFIC RESOURCE
This company has been a terrific help to us (I work for Trican Well Service) in sourcing the Micron Ram Memory we needed for our Siemens computers. Great service! And great pricing! I know when the product is shipping and when it will arrive, all the way through the ordering process.

GO TO SOURCE
When I can't find an obsolete part, I first call GID and they'll come up with my parts every time. Great customer service and follow up as well. Scott emails me from time to time to touch base and see if we're having trouble finding something.....which is often with our 25 yr old equipment.
