Analog Technologies ATH100KR8B3950K Ultra-Stable Miniature Thermistor

Product Overview
The ATH100KR8B3950K is an ultra-stable miniature thermistor featuring glass encapsulation for enhanced long-term stability and reliability. Its small size, high resistance accuracy, and quick response time make it ideal for precise temperature sensing in demanding applications such as laser diodes and optical components. It is also a cost-effective solution for automotive electronics, industrial electronics, and home appliances requiring accurate temperature monitoring. The thermistor offers superior performance compared to conventional epoxy-encapsulated types, with a wider operating temperature range and improved resistance to heat and climatic conditions.

Handling and Storage Recommendations

• Store in original packaging, unopened until use.
• Recommended storage temperature: -25C to +45C.
• Relative humidity: < 75% average, < 95% maximum (no dew precipitation).
• Avoid exposure to heat or direct sunlight during storage.
• Prevent contamination of the thermistor surface.
• Do not store in environments with corrosive gases (SOx, Cl, etc.).
• Use thermistors from opened packages as soon as possible.
• Solder within 12 months (SMDs) or 24 months (leaded) of shipment.
• Handle with gloves to avoid contamination and damage.
• Use resin-type or non-activated flux for soldering.
• Ensure proper preheating before soldering to prevent cracks.
• Avoid rapid cooling by dipping in solvent.
• Completely remove flux residue after soldering.
