Taconic TLY-5 Avionics & Aerospace Grade Low DK2.2 DF0.0009 Base Material
TLY-5 Copper clad laminates are produced using ultra-lightweight woven fiberglass, delivering notably higher dimensional stability than chopped fiber-reinforced PTFE composites. The woven matrix of Taconic TLY-5 laminate creates a mechanically robust laminate, ideal for high-volume manufacturing processes. Its low dissipation factor allows for reliable application in 77 GHz automotive radar systems, as well as other antennas operating at millimeter-wave frequencies.
Comparative OEM testing at 77 GHz between lightly reinforced TLY-5 CCL and its closest chopped fiber-reinforced competitor has demonstrated equivalent insertion losses and dielectric properties, enabling "drop-in" compatibility. A key advantage ofTLY-5 base material is its significantly higher manufacturing yield rate. The dielectric constant of TLY-5 PCB substrate ranges from 2.17 to 2.40, and for most thicknesses, it can be specified to any value within this range with a tolerance of±0.02. At 10 GHz, the dissipation factor is approximately 0.0009.
Typical applications include satellite communications, automotive radar, filters, couplers, avionics, and phased array antennas.
