I-Tera® MT40 Tg 200, Td 360
Dk 3.45, Df 0.0031

I-Tera® MT laminate materials exhibit exceptional electrical properties which are very stable over a broad frequency and temperature range.

I-Tera® MT40 is suitable for many of today’s high speed digital and RF/microwave printed circuit designs. I-Tera MT40 features a dielectric constant (Dk) that is stable between -55°C and +125°C up to 20 GHz up to W-band frequencies. In addition, I-Tera MT40 offers a lower dissipation factor (Df) of 0.0031 making it a cost effective alternative to PTFE and other commercial microwave and high-speed digital laminate materials.

I-Tera MT40 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-Tera MT40 does not require any special through hole treatments commonly needed when processing PTFE based laminate materials.
