Application Notes
To ensure reliable performance at high voltages care should
be taken to avoid potential sources of ionic contamination
contacting the resistor body, for example, flux applied by
spraying, encapsulation materials or contaminants from the
environment of use.
Packaging
All MH series resistors are supplied tape packed ready for
loading on automatic sequencing and insertion machines.
Component wires will not protrude beyond the outside edge
of the tape.
Alternative packing available by request.
Lead Formed Resistors can also be supplied. Standard options
of Lancet, Radial and Goal Post forming are shown in the
Lead Form information sheet.
