General Caution

NJRC offers a variety of microwave components intended for particularapplications. It is important that you select the proper component for yourintended application. You may contact NJRC's sales office or salesrepresentatives, if you are uncertain about the products listed in thecatalog and the specification sheets.

Special care is required in designing devices, machinery or equipment,which demand high levels of reliability. This is particularly important whendesigning critical components or systems whose foreseeable failure canresult in situations that could adversely affect health or safety. Indesigning such critical devices, equipment or machinery, carefulconsideration should be given to, amongst other things, their safetydesign, fail-safe design, back-up and redundancy systems, and diffusiondesign.

The products listed in the catalog and specification sheets may not beappropriate for use in certain equipment where reliability is critical orwhere the products may be subjected to extreme conditions. You shouldconsult our sales office or sales representatives before using the productsin any of the following types of equipment.* Aerospace Equipment* Equipment Used in the Deep Sea* Power Generator Control Equipment (nuclear, steam, hydraulic)* Life Maintenance Medical Equipment* Fire Alarm/Intruder Detector* Vehicle Control Equipment (automobile, airplane, railroad, ship, etc.)* Various Safety Equipment

NJRC strives to produce reliable and high quality microwave components.NJRC's microwave components are intended for specific applications andrequire proper maintenance and handling. To enhance the performanceand service of NJRC's microwave components, the devices, machinery orequipment into which they are integrated should undergo preventativemaintenance and inspection at regularly scheduled intervals. Failure toproperly maintain equipment and machinery incorporating these productscan result in catastrophic system failures.

To ensure the highest levels of reliability, NJRC products must always beproperly handled. The introduction of external contaminants (e.g. dust, oilor cosmetics) can result in failures of microwave components.
