Sensor Scientific small bead thermistors offer the advantages of small size and mass, very fast thermal response time, extreme sensitivity to current and voltage changes, and high stability. Typical applications include thermodilution cardiac catheters and other biomedical assemblies, fluid flow and fluid level measurement, thermal conductivity measurement, gas analysis, and small surface area temperature measurement.

FEATURES:

• SUPERIOR STABILITY

• LOW THERMAL MASS

OPTIONS:

• CUSTOM LEAD LENGTHS
• NON-STANDARD RESISTANCE TOLERANCES
• PRECISION CALIBRATION AT MULTIPLE TEMPERATURES
• CUSTOM VALUE-ADDED ASSEMBLY OPTIONS

SPECIFICATIONS:

• TIME CONSTANT: 1 SEC. TYP. IN STILL AIR
• DISSIPATION CONSTANT: 0.1mW/°C IN STILL AIR
• MAXIMUM OPERATING TEMPERATURE: 300°C.
• STANDARD RESISTANCE TOLERANCE: ±25%

PART NUMBER SPECIFICATION:

To specify a part number, the following sequence should be used:

S14A10325 specifies a small bead thermistor with adjacent leads, 10000 ohms at 25 Deg. C., with a resistance tolerance of ±25%.

S14A10325 indicates small bead thermistor, .014" (0.36mm) nominal diameter

S14A10325 indicates lead configuration A: Adjacent leads B: Opposite leads

S14A10325 indicates zero power resistance at 25°C. The first two digits indicate significant figures, and the last digit indicates the number of zeros following the significant figures. In this example, "103" represents 10000 ohms.

S14A10325 indicates the resistance tolerance at 25°C, expressed in ±%. In this example, "25" indicates the standard tolerance of ±25%. Other typical tolerances include ±1%, 2%, 5%, 10%, 15%, 20%, and 30%.
