This Intertechnik air core inductor provides consistent performance with a tight tolerance. It has an outer diameter of 55mm." *Wait, let me check the "strongest benefit" part again. "Optimise signal filtering" is good.* *Wait, let's check the keyword again: "LU55/2.2/100 | 2,2 mH | 0,89 Ω | 3% | 18 AWG | Air Coil".* *Final Polish:* Optimise signal filtering in audio and electronic circuits using the LU55/2.2/100 | 2,2 mH | 0,89 Ω | 3% | 18 AWG | Air Coil. This Intertechnik component is engineered for precise inductance and stability. It features a 55mm outer diameter. *Character count check:* "Optimise signal filtering in audio and electronic circuits using the LU55/2.2/100 | 2,2 mH | 0,89 Ω | 3% | 18 AWG | Air Coil. This Intertechnik component is engineered for precise inductance and stability. It features a 55mm outer diameter." Length: 236 characters. *Constraints check:* - 2-3 sentences? Yes (3). - Max 300 chars? Yes. - First sentence starts with benefit? Yes ("Optimise signal filtering..."). - Keyword included? Yes. - No hype words? Yes. - Last sentence technical detail? Yes (55mm outer diameter). - Plain prose? Yes. - UK English? Yes ("Optimise"). - Output only text? Yes. Wait, let's try a version with 2 sentences to be even more concise. "Optimise signal filtering in audio and electronic circuits using the LU55/2.2/100 | 2,2 mH | 0,89 Ω | 3% | 18 AWG | Air Coil. This Intertechnik inductor features an outer diameter of 55mm." This is very clean. Let's double-check the keyword for any typos: "LU55/2.2/100 | 2,2 mH | 0,89 Ω | 3% | 18 AWG | Air Coil". Correct. Final check on "hype words": "Optimise" is a function, not a hype word. "Precise" is a technical description. "Engineered" is descriptive. "Perfect/Fantastic/Premium/Best" are the ones to avoid. Let's go with: Optimise signal filtering in audio and electronic circuits using the LU55/2.2/100 | 2,2 mH | 0,89 Ω | 3% | 18 AWG | Air Coil. This Intertechnik component ensures stable performance with a tight tolerance. It features an outer diameter of 55mm. Character count: 238. Wait, the prompt says "The first sentence must start with the strongest benefit or use case, not the product name". "Optimise signal filtering..." -> Starts with benefit. Correct. Final check on "British English": "Optimise" (UK). "Centimetre/Diameter" (Standard). Let's use: Optimise signal filtering in audio and electronic circuits using the LU55/2.2/100 | 2,2 mH | 0,89 Ω | 3% | 18 AWG | Air Coil. This Intertechnik component provides stable inductance for precise applications. It features an outer diameter of 55mm. Total characters: 236. Is "stable inductance" or "precise applications" hype? "Stable" is a technical property. "Precise" is a technical property. Compared to "Perfect" or "Premium", these are acceptable for professional e-commerce copy. Let's try one more just to be safe. "Improve signal filtering in audio and electronic circuits using the LU55/2.2/100 | 2,2 mH | 0,89 Ω | 3% | 18 AWG | Air Coil. This Intertechnik air core inductor is designed for reliability and stability. It has a winding width of 23mm." Length: 230. Let's use the "Optimise" one as it sounds more "experienced UK copywriter". Final selection: Optimise signal filtering in audio and electronic circuits using the LU55/2.2/100 | 2,2 mH | 0,89 Ω | 3% | 18 AWG | Air Coil. This Intertechnik component provides stable inductance for technical applications. It features an outer diameter of 55mm. Wait, let me check the keyword again. "LU55/2.2/100 | 2,2 mH | 0,89 Ω | 3% | 18 AWG | Air Coil" The keyword provided in the prompt uses commas for decimals (2,2 mH and 0,89 Ω). I must keep the keyword *exactly* as provided.
