Filter Coating Marking (Color Dot): Apply a colored marking on the filter coating surface at the position shown in the diagram. Requirements:** Highly visible color; Use a dry pigment that is non-powdering, non-volatile, and has a diameter < 0.15 mm.5. Surface Quality: Clean surfaces. Chipped corners: < 0.2 mm. Chipped edges: < 0.05 mm. No scratches.6. Environmental Specifications: Operating Temperature: -40°C to +85°C Storage Temperature: -40°C to +85°C Wavelength Temperature Drift: ≤ 0.2 pm/°C (Note: Corrected "0.2Pm" to "0.2 pm")7. Compliance: Must comply with the ROHS Directive.Key Translation Notes: (ch sn):Translated as Insertion Loss (IL), the standard term. (gélí dù): Translated as Isolation, the standard term.PDL (Polarization Dependent Loss):Kept as the acronym PDL, which is universally understood. (lgungpiàn mó miàn zuò cisè biojì): Translated as Filter Coating Marking (Color Dot) to clearly indicate it's a colored mark on the coating side.(sèci xngmù): Translated as Highly visible color., (gnzào qi bùnéng biàn chéng fnmò, bù yì huf de wùzhì):Translated precisely as dry pigment that is non-powdering, non-volatile. "Non-powdering" covers "cannot become powder".(zhíjìng):Translated as diameter.(biomiàn qngjié): Translated as Clean surfaces.(bng jio): Translated as Chipped corners. "Chip" is the standard term for small breaks at corners/edges.(bng bin): Translated as Chipped edges.(wú huáhén): Translated as No scratches.(gngzuò huánjìng wndù): Translated as Operating Temperature. (cúnch wndù):Translated as Storage Temperature.

"Comply with" is the standard phrasing for regulations.SpecificationInsertion Loss (IL)< 0.25 dBIsolation:> 30 dBPolarization Dependent Loss (PDL)≤ 0.05 dBFilter Coating Marking (Color Dot)Apply a colored marking on the filter coating surface at the position shown in the diagram.RequirementsHighly visible color; Use a dry pigment that is non-powdering, non-volatile, and has a diameter < 0.15 mm.Surface QualityClean surfacesChipped corners< 0.2 mmChipped edges< 0.05 mmStorage Temperature-40°C to +85°CCertificationsPacking & DeliveryFAQ1.Do you provide after-sales service?Of course, we offer comprehensive after-sales service. If you encounter any issues with our products during use, please feel free to contact us, and we will do our best to solve your problems. Within the warranty period, if there are any quality issues with the product, we will replace or repair it for free.2.How can I place an order for your thyristor products?You can place an order by consulting our sales staff online, sending a purchase order to our email, or calling our order hotline directly.3.Do you provide samples, and how is the charging handled?For low-value standard products, we can provide free samples for testing, but the customer is responsible for the shipping costs. High-value product samples come with a discount, which can be discussed on a case-by-case basis.4.Do you have SCR Power Regulators products in stock?We have some conventional models in stock. For specific inventory, please consult our sales staff. For non-stock products, our delivery time is usually 15-30 days.5.How can one determine if a thyristor is damaged?You can determine if a thyristor is damaged by checking if there are any anomalies in its forward and reverse blocking voltages. If so, the thyristor may be damaged. For specific products, please consult an engineer for detailed numerical reference and guidance.
