Most absorber materials are broadband by design. They spread their attenuation across a frequency range, accepting a lower peak in exchange for wider coverage. That’s the right tradeoff when the problem frequency is unknown or the application spans multiple bands. But when an engineer knows the exact resonance frequency, say a cavity ringing at 6.2 GHz or a coupling path peaking at 14.8 GHz, broadband absorbers leave significant performance on the table. The TF Series takes the opposite approach: each part number is a specific formulation tuned for maximum attenuation at a single target frequency between 2.0 and 18.0 GHz. Peak absorption exceeds -20 dB at every standard tuned frequency.

The TF Series is most commonly deployed when an engineer has already characterized the problem and identified a specific frequency that needs aggressive attenuation, typically a cavity resonance, a known coupling path, or a specific emissions test point that won’t pass with broadband materials. It’s also used in test fixtures and reference systems where peak performance at a known frequency is more important than wide coverage.

The TF Series is the only series in the magnetic elastomer lineup where both thickness and loading level are tunable parameters. Each part number combines a specific loading level and thickness selected to deliver maximum attenuation at the target frequency. Custom target frequencies are available when a standard part number doesn’t align with the application requirement. Standard PSA backing and in-house die-cutting allow direct integration into shield assemblies, with the formulation itself tuned to the engineering problem rather than asking the engineer to compromise on band coverage.
