Although the use of proprietary heat sinks with lower thermal resistance is
acceptable, up rating is not recommended. The use of proprietary heat sink
compound to improve thermal conductivity is essential.
With a maximum inductance of 80nH
and a rated power of 600W (60°C
Heatsink) in a 57mm x 60mm casing,
the BDS600 offers high power
density over a wide range of ohmic
values (0R5 – 100K).
This high power density resistor is
made from quality materials for
optimum reliability and stability with
very low partial discharge.
Tyco can test resistors to conform
to relevant international, MIL or
customer specifications, and will
advise on the use of resistors for
pulse applications (special pulse
duty options available) and high
voltage usage (high voltage designs
available). The BDS600 offers a
limiting element voltage of 5kVac
rms, and 10kV isolation voltage
(terminal to heatsink).
Resistors with 1% tolerance, alterna-
tive terminations or flying leads are
available, and custom designs are
welcome.
This product is available via
distribution.
