Discharge resistors can be found in
numerous catalogs of electrical component
makers. When selecting the exact resistor,
an engineer must pay attention to its
value, which impacts discharge transients,
and rated power, which defines energy
dissipation capability."

reliable protection against surge currents. The CHV
series of high-voltage chip resistors are designed
to handle high voltage levels, making them well-
suited for use in high-voltage pre-charging circuits.
Finally, the PWR series of high-power resistors are
available in a variety of housing types—including
DPAK, D2PAK, TO220, and TO221—and are capable
of handling high power dissipation.

PWR series are high-power resistors made
with thick film resistive elements on a white alumina
ceramic substrate for contact with a heat sink which
will be electrically isolated from the resistive element.
These resistors are capable of handling high power
dissipation of up to 50 Watts and have excellent
pulse load energy capability.
