The Bourns® BTN02G and BTN04G Series provide essential and highly accurate thermal management for today’s sophisticated and sensitive electronics applications

RIVERSIDE, Calif., June 4, 2025 - Bourns, Inc., a leading manufacturer and supplier of electronic components for power, protection, and sensing solutions, today announced its BTN02G and BTN04G Series SMD Negative Temperature Coefficient (NTC) Thermistors. Designed as a high-precision and compact temperature sensing and compensation solution, Bourns’ new NTC thermistors provide essential thermal management for today’s more sophisticated and sensitive mobile devices, home appliances, Li-ion battery packs, LCD displays and other electronic equipment.

These new thermistors feature resistance that is inversely proportional to the temperature, enabling accurate temperature measurement. The advanced and high reliability design of the BTN02G and BTN04G series combines semiconducting ceramics and internal electrodes, providing the capability to uniformly and smoothly change resistance values over a wide temperature range. In addition to the standard ±3 percent and ±5 percent high-precision resistance tolerances, Bourns’ latest NTC thermistors are also available in ±1 percent and ±2 percent resistance tolerances. The series’ B-Value tolerance is highly accurate at ±1 percent, making them superior temperature sensing solutions.

Bourns® BTN02G and BTN04G Series SMD NTC Thermistors are available now through Bourns’ authorized distribution partners, and are RoHS* compliant and halogen free**. For more detailed product information, please see: bourns.com/products/thermal-sensing-devices/ntc-thermistors.
