Glass Encapsulated PTC Thermistors

Sensor Scientific glass encapsulated PTC (positive temperature coefficient) thermistors offer the advantage of a near-linear resistance vs. temperature response in a hermetic DO-35 package. The linear response is a significant advantage in temperature compensation applications. Bulk packaging is standard; tape and reel packaging is available as an option.
FEATURES:
• HIGH STABILITY
• LOW COST
• NEAR-LINEAR RESISTANCE V. TEMPERATURE RESPONSE
• HERMETICALLY SEALED DO-35 PACKAGE
OPTIONS:
• NON-STANDARD RESISTANCE VALUES
• NON-STANDARD TOLERANCES
• TAPE AND REEL PACKAGING
• VALUE ADDED CUSTOM PROBE ASSEMBLIES
SPECIFICATIONS:
• THERMAL TIME CONSTANT: 8 SECONDS (STILL AIR), 0.4 SECONDS (STIRRED OIL)
• DISSIPATION CONSTANT: 2 mW/°C
• MAXIMUM OPERATING TEMPERATURE: 150°C
• TEMPERATURE COEFFICIENT
