Type MPR Series
This small size non-inductive, high
power resistor is an innovative and
significant first for Tyco Electronics.
Occupying a standard T0220
package it is ideally suited to
positions where high power
dissipation, small size and tight
tolerance are key design
requirements.
This series is an ideal solution for
the output side of high speed pulse
generators, a surge absorption
resistor in switch mode power
supplies and for monitors, display
terminals, scientific workstations
and other brown and white goods.
