NJRC strives to produce reliable and high quality microwave components.

NJRC's microwave components are intended for specific applications and

require proper maintenance and handling. To enhance the performance

and service of NJRC's microwave components, the devices, machinery or

equipment into which they are integrated should undergo preventative

maintenance and inspection at regularly scheduled intervals. Failure to

properly maintain equipment and machinery incorporating these products

can result in catastrophic system failures.

To ensure the highest levels of reliability, NJRC products must always be

properly handled. The introduction of external contaminants (e.g. dust, oil

or cosmetics) can result in failures of microwave components.

NJRC offers a variety of microwave components intended for particular

applications. It is important that you select the proper component for your

intended application. You may contact NJRC's sales office or sales

representatives, if you are uncertain about the products listed in the

catalog and the specification sheets.

Special care is required in designing devices, machinery or equipment,

which demand high levels of reliability. This is particularly important when

designing critical components or systems whose foreseeable failure can

result in situations that could adversely affect health or safety. In

designing such critical devices, equipment or machinery, careful

consideration should be given to, amongst other things, their safety

design, fail-safe design, back-up and redundancy systems, and diffusion

design.

The products listed in the catalog and specification sheets may not be

appropriate for use in certain equipment where reliability is critical or

where the products may be subjected to extreme conditions. You should

consult our sales office or sales representatives before using the products

in 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
