# 10KF3950 (Component) ## Description 10KF3950 is an NTC (Negative Temperature Coefficient) thermistor with a nominal resistance of 10 kΩ at 25°C and a B-value of 3950 K. Its resistance decreases as temperature increases, making it suitable for temperature sensing, compensation, monitoring, and control applications in electronic circuits. It is commonly available in compact SMD packages such as 0402, 0603, and 0805. Key Features Resistance at 25°C: 10 kΩ B Constant (25/50°C): 3950 K ±1% Resistance Tolerance: ±1% Operating Temperature Range: -40°C to +125°C Rated Power: 100 mW Fast thermal response due to small chip size High sensitivity to temperature changes RoHS compliant Available in 0402, 0603, and 0805 SMD packages for space-constrained designs Typical Applications Battery pack temperature monitoring Power supply thermal protection Consumer electronics Industrial control systems Automotive electronics HVAC equipment Smart home devices Temperature compensation circuits #CommonPartsLibrary #thermistor #NTC ## Component Details - **Owner:** lcsc - **Created:** 11/5/2024 - **Last Updated:** 6/3/2026 - **Visibility:** Public - **Manufacturer Name:** KUU - **JLCPCB Part Class:** Extended Part - **Part Type:** NTC Thermistors - **Package or Case Code:** R0603 - **LCSC Part Number:** C2892547 - **License:** https://creativecommons.org/licenses/by/4.0/ - **Manufacturer Part Number:** KNTC0603/10KF3950 - **Datasheet URL:** https://www.lcsc.com/datasheet/C2892547.pdf?spm=wm.sxq.inf.ggs&lcsc_vid=T1kIXgFeT1NaU1RXQFBbUlUHT1cKU1NXFVBeX1VSTlAxVlNeR1VbVFNQRlJfUDsOAxUeFF5JWBYZEEoKFBINSQcJGk4dAgUUFAk%3D - **Used in:** 82 projects ## Distributor Pricing (qty 1) *Pricing shown for quantity 1.
