Overview of TLF-35A
TLF-35A is an economical RF material designed for low-cost, high-volume commercial microwave and radio frequency applications. This laminate is particularly noted for its excellent peel strength with 1/2 ounce and 1 ounce copper, surpassing standard epoxy materials. This quality is crucial for rework situations.
The TLF-35A features an extremely low moisture absorption rate and a low dissipation factor, which helps to reduce phase shift across frequencies. Its design incorporates woven fabrics, ensuring excellent dimensional stability. Additionally, TLF-35A materials have a flammability rating of V-0 and are tested according to IPC-TM-650 standards.
The dielectric constant of TLF-35A is low at 3.5 ± 0.05, with a minimal dissipation factor of 0.002.
Key Benefits:
1.Cost-Effective: Ideal for budget-sensitive projects.
2.Exceptional Peel Strength: Ensures reliability during rework.
3.Ultra-Low Dissipation Factor: Minimizes phase shift across frequencies.
4.Low Moisture Absorption: Maintains performance in varying environmental conditions.
5.High Thermal Reliability: Suitable for demanding thermal environments.
Typical Applications:
Filters, couplers, splitters, combiners, and mixers
Antennas
High Power Amplifiers, TMAs, TMBs, LNAs
Repeaters
Passive RF components
