Isola I-TERA MT

I-Terra MT laminate materials exhibit exceptional electrical properties which are very stable over a broad frequency and temperature range. I-Terra MT is suitable for many of today’s high speed digital and RF/microwave printed circuit designs. I-Terra MT features a Dielectric Constant (Dk) that is stable between -55C and 125C, up to 20 GHz. In addition, I-Terra MT offers a lower dissipation factor (Df) of 0.0036 making it a cost effective alternative to PTFE and other commercial microwave and high speed digital laminate materials. I-Terra MT laminate materials are currently being offered in both laminate and prepreg form in typical thicknesses and standard panel sizes. This provides a complete materials solution package for high-speed digital multilayer, hybrid, RF/microwave, multilayer and double-sided printed circuit designs. I-terra MT does not require any special through hole treatments commonly needed when processing PTFE-based laminate materials.
