LMF 3995-RS232 RFI/EMI Filter

Marking and Documentation

The filter contains an identification label that states manufacturer’s name, model

of filter and serial number. The label also establishes the frequencies of

operation, voltage, current rating and impedance (if applicable). The filter

contains necessary labels indicating which terminals are grounded, danger of

high voltage and the need for discharging of capacitors.

Filter Testing

The ability to provide the customer with a highly reliable product demands

repeatability and controlled processing. We have achieved this objective using

testing procedures to verity that filter products conform to original design

parameters. Testing is performed in accordance with Military Specifications that

include MIL-F-15733, MIL-STD-220A, as well as commercial specification UL-

1283. Precision electronic test instruments are utilized to accurately measure the

characteristics of each filter. Test reports are available upon request.

Protection Against Electric Shock

Protective earthing is accomplished by means of a screwed on cover that is in

contact with the body of the filter. This cover protects against accidental contact

with live terminals and also provides a ground path by means of the body of the

filter. The filter, when in use, should be permanently grounded by means of

grounding connection and also by contact of the filter to the grounded surface to

which it is attached. This arrangement provides for very low impedance from the

filter body to earth ground.
