With less than 40nH inductance and a 100Watt power rating in an easy-mounting
38mm x 25mm Isotop case, the BDS100 offers high power density over a wide range of
ohmic values (R47 – 1M0) and benefits from 10 years experience in the field. Available in
6 resistor configurations with 2 or 4 easy to connect terminals, the resistors are made from
quality materials for optimum reliability and stability with very low partial discharge.
TE Connectivity can test resistors to conform to relevant customer specifications, and will
advise on the use of resistors for pulse energy and high voltage applications (HV designs
available). Resistors with alternative terminations or flying leads are available, and custom
designs are welcome. This product is available via distribution.

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.
