ETC MCH0504HFB Military grade high voltage chip resistor Datasheet

MCH Series
Military Grade High Voltage Chip Resistors
OhmCraft’s revolutionary fine line, thick film technology, called FineFilm, provides an
entirely new level of stability and voltage ratings in chip resistors. Our MCH series of resistors meets
the same high standards as our HVC series, but with the added feature of an extended temperature range.

Low TCR and VCR
Very Low noise
Extended Temperature Range
(-55ºC to +125ºC)
♦ Custom Configurations
The usual hybrid technologies for manufacturing resistors
depend upon composite materials that have limitations.
Traditional thick-film methods severely limit
performance characteristics and thin-film methods are
limited in attainable ohmic values. The FineFilm method
of manufacturing offers the best characteristics of both
methods, plus adds many unique features. FineFilm
resistors feature a longer, high-aspect ratio trace of lower
resistivity film. The combination of long line, highaspect ratio, and higher conductivity film, give FineFilm
resistors unmatched design efficiency, versatility, linearity,
stability and low noise. The FineFilm method allows
control of process parameters to very tight tolerances. The
result is chip resistors with outstanding stability and high
voltage ratings.
Using the same method, a complete line of FineFilm leaded
resistors, dividers and networks are manufactured. For
information on those products, please refer to the
appropriate data sheets.
Maximum Continuous Voltage:
FineFilm high voltage chip resistors offer voltage
ratings that are much higher than conventional screen
printed resistors of the same size and resistive value.

the first three numbers are the significant value, and the
forth number is the
number of zeros.
Example: For a High Voltage, 125 Meg-ohm resistor with case size of 0805,
a TCR of + 50 ppm/C, a +1% tolerance, and wrap-around solderable
terminations - the part number would be:
