Thermal Information
In full operation (10–12 ports), the NSE-8G is designed to operate over a wide
temperature range when used with a heat sink with a worst case Junction to case
Tj (Tjc) of 1 °C/W and is suited for industrial applications such as outside plant
equipment
Maximum long-term operating junction temperature to ensure adequate long-term life
105
0C
Maximum junction temperature for short-term excursions with guaranteed continued functional
performance.

Notes
1.
Short-term is understood as the definition stated in Telcordia Generic Requirements GR-63-Core
2.
ΘJC, the junction-to-case thermal resistance is a measured nominal value + 2 sigma. ΘJB, the junction-
to-board thermal resistance is obtained by simulating conditions described in JEDEC Standard, JESD
51
3.
ΘSA is the thermal resistance of the heat sink to ambient. ΘCS is the thermal resistance of the heat sink
attached material
4.
The actual
ΘSA required may vary according to the air speed at the location of the device in the system
with all the components in place
