Product Description
Product Overview
The NTC 1.5D-11/P=7.5/L=3.2 is a power NTC thermistor designed for surge current suppression. It features a small size, high power handling, fast response, high reliability, and long life. The thermistor is characterized by a high material constant (B value) and low residual resistance, making it suitable for a wide operating temperature range. It is commonly used in switch mode power supplies, adapters, converters, LED driver circuits, electronic ballasts, electric heaters, electric motors, and for filament protection in CRT, displays, and lighting fixtures.
