Description:
These power resistors are designed to tolerate high current and establish a low thermal resistance interface with the circuit board. A
lower thermal resistance more efficiently sinks heat to the board, enabling a larger effective area for heat dissipation. As a result,
much lower surface temperatures are achievable in comparison to standard chip resistors for the same chip size and applied power.
The BP series effectively integrates the power resistor with the board, providing a thermal resistance comparable with aluminum
heat-sinks.

Notes:
1. Dependent on effective thermal conductivity of board construction/land design and size of board - greater power capability for
board/land with lower thermal resistance. For relatively high thermal resistance mountings, the power resistors are capable of
reflowing solder bonds before device damage occurs.
2. Per MIL-PRF-55342 (-55/25/125ºC).
3. Per MIL-PRF-55342, see derating curve.
4. Per IEC 60115-1.
