Isola IS680

IS680 laminate materials exhibit exceptional electrical properties which are very stable over a broad frequency and temperature range. IS680 is suitable for many of taday’s high speed digital and RF/microwave printed circuit designs. It features a Dielectric Constant (Dk) that is stable between -55C and 125C, up to 20 GHz. In addition, IS680 offers a lower dissipation factor (Df) of 0.003 making it a cost effective alternative to PTFE and other commercial microwave and high speed dgital laminate materials.
