Silicon Spreading Resistance Temperature Sensor in
Surface Mount Technology
Features
• Temperature dependent Resistor with Positive
Temperature Coefficient
• SMD plastic package for very small thermal time
constants
• Fast response
• High reliability due to multilayer gold contacts
• n-conducting silicon crystal
• Polarity independent due to symmetrical
construction
• Available selected in
±
1% tolerance groups
