340 nm UV LED Chips at the Upper Edge of the Range

Reading the endpoint honestly

A catalogue range has two ends, and this is the far one. The catalogue names no application for this band: it is not listed among the catalogue's germicidal bands, and phototherapy is the application the catalogue attaches to 310 nm. What the endpoint marks is the full span of the company's published chip range — 255–340 nm, with the germicidal bands at 255–280 nm, the named bands at 295 and 310 nm, and 340 nm closing the range. An enquiry for this band names the centre wavelength, the tolerance, the form and the quantities the design requires.

340 nm at Jason

The endpoint comes from the company's own published range statement: chips across 255–340 nm, with the main production bands at 260–320 nm. The 340 nm band therefore sits outside the published main range, at the catalogue's edge. The published main range is the 260–320 nm span; the wider published range that contains this band runs from 255 to 340 nm. The forms in which it is supplied — bare die, or a specific package format — and the ratings recorded for a given model are established per model in the enquiry exchange. A programme planning volume at the endpoint should open that conversation early, naming the target band, the form and the quantities, so the confirmation covers the exact model the design will use.

Forms at the endpoint

The catalogue's form families are bare chip die for integrators who run their own packaging, SMD packages in the 3535 and 6868 format families, and finished disinfection modules. Which of those forms the 340 nm band is supplied in is a per-model question, settled in the enquiry exchange for the exact model the design names — the published range statement establishes the band's place in the catalogue, not the form a given model takes. An enquiry for the endpoint should therefore name the form alongside the band, so the confirmation answers the configuration the product will actually build, and ask which spectral and electrical ratings are recorded for that model in that form.

Specifying a 340 nm device

The enquiry for this band should carry the spectral detail the design assumes: the centre wavelength and tolerance, the spectral width it can accept, the form to build with, and the quantities involved. Ask what spectral and electrical data is recorded for the named model, and have what exists confirmed in the enquiry exchange.

Is 340 nm inside the company's published range?

Yes. The company's published range is 255–340 nm, and 340 nm is that range's endpoint. Supply for a named model is confirmed per model in the enquiry exchange.

The endpoint in the record

The endpoint comes from the company's own published range statement: chips across 255–340 nm. The wider range and the main production range are separate statements — the main bands are published as 260–320 nm — and the 340 nm band sits at the edge of the wider one. An enquiry for the endpoint names the centre wavelength, the tolerance, the spectral width the design can accept, the form and the quantities, with the programme timing alongside them.
