SPECIFICATIONS:
The SD series of glass encapsulated thermistors
offer the tighter tolerances and low costs associ-
ated with wafer thermistors, with the reliability and
high temperature capabilities normally associated
with glass probe thermistors. The rugged DO-35
diode style package is resistant to enviromental
stress. Tape and reel packaging is available for
auto-insertion applications.
• THERMAL TIME CONSTANT: 5 SECONDS (STILL AIR), 0.5
SECONDS (STIRRED OIL)
• DISSIPATION CONSTANT: 2 mW/°C
• MAXIMUM OPERATING TEMPERATURE: 300°C
