Bulk Metal^® Foil Technology Power Current Sensing Resistors
with TCR of 5 ppm/°C and Power Rating up to 7 Watts
Any value available within resistance range
These Bulk Metal^® Foil power current sensing resistors are
direct replacements for certain wirewound devices but
without the inductive characteristics of wirewounds. The
anodized aluminum housing is drilled and countersunk to
accept flat head screws for thermal mounting. Because the
device is internally Kelvin connected, there is no restriction
on the lead lengths as would be the case if this were a two
terminal device. Frequently used in YIG oscillator circuits
these devices contribute to superior frequency stability.
