Product Specification
| Description | Through Hole,P=5mm NTC Thermistors RoHS | Mfr. Part # | NTC2.5D-7KMF3FG |
| Package | Through Hole,P=5mm | Model Number | NTC2.5D-7KMF3FG |
The NTC 2.5D-7/P=5/L=3.5 internal bent lead green silicone power thermistor, model NTC2.5D-7KMF3FG, is designed for surge current suppression. It features a small size with high power handling, fast response, high reliability, and a long lifespan. The thermistor offers a large material constant (B value) and low residual resistance, operating across a wide temperature range. It is suitable for applications including switch mode power supplies, adapters, LED drivers, electronic ballasts, electric heaters, electric motors, and protection for filaments in display devices and lighting.
