    MTL700, 4700 or 7000 Series Zener Barriers

    Choosing a barrier,MTL Instruments

    The MTL7700 Series, with their advanced features, should be regarded as your first choice for all new designs or installations. The recommendations below are based therefore on the MTL7700 Series.

    Users of MTL700, 4700 or 7000 Series products can also use the guide because of MTL's consistent numbering policy. Products, in any barrier series, that have the same two last digits (ignoring letters and '+' symbols) will have very similar characteristics, e.g. MTL7787 and MTL787.
