• When to choose PSE400L-34G-P: Select this model if your cable assemblies face heavy mechanical drag, constant dynamic flexing, or severe physical abrasion (e.g., field testing vehicles, outdoor radar systems, or robotic test rigs). The thick TPU outer jacket provides maximum ruggedness and flexibility, though limited to 85°C.
• When to choose PSE400L-34G-F: Choose this model if your setup requires ultra-high phase accuracy (±0.2 °/GHz) and amplitude stability in thermal chambers or high-precision laboratory test benches operating up to 125°C.
• When to choose PS400L-34G-F: Choose the standard model if you need a compact (4.00mm) low-loss flexible solution for general internal chassis interconnection with standard high-temperature (125°C) requirements.
Frequently Asked Questions
Why does PSE400L-34G-P use a TPU jacket instead of FEP?
TPU (Thermoplastic Polyurethane) provides superior abrasion resistance, tear strength, and flexibility compared to FEP, making it the ideal choice for field-deployable assemblies subjected to constant flexing and dragging.
What is the maximum operating temperature for PSE400L-34G-P?
Due to the mechanical properties of the TPU outer jacket, the maximum continuous operating temperature is +85 ℃ (compared to +125 ℃ for FEP versions).
Does the thicker 5.00mm outer diameter affect electrical performance?
No. The core coaxial electrical structure maintains a 50 Ohm impedance, 34 GHz frequency cutoff, and identical attenuation values. The additional thickness is purely protective jacket material.
