UVC LED 3535: The LED35 Package Family

The family

The family lists six catalogued models inside one nominal footprint class, and no comparison across them is recorded in this site's material, so which model carries which band and output class is established in the enquiry exchange. Land pattern, reflow profile and optical alignment are properties of each model: ask what is documented for the model you are sourcing rather than assuming those fields are recorded identically — or at all — across the family. A board designed around one LED35 model should therefore be re-checked against the documentation of any other model before substitution, even inside the same family: the format class is shared, but drop-in interchangeability between models is not assumed.

Known facts, per-model questions, buyer inputs

• Known from the catalogue: the LED35 family name, its six catalogued models, and the nominal 3535 format class.
• To establish per model in the enquiry exchange: which of band and output class, exact dimensions and tolerances, land pattern, reflow conditions, optical characteristics and thermal ratings are documented for the named model, and what they show.
• What buyers provide: target band, board material and thermal design, intended drive point, application and quantities — so the documentation confirmed matches the design being built.

The family in the programme

The LED35 family sits inside the package programme alongside the LED68 family. Which module or product a given LED35 model is integrated into is a per-model matter, confirmed in the enquiry exchange against the design's geometry and duty — the module programme covers the assembled forms in the same catalogue.

Design notes

At 3535 scale, state the thermal design in the enquiry: the board material, the thermal path and the drive point the design will run at. Confirm the drive point against the model's documented ratings at the design's operating temperature rather than at room-temperature test conditions, and ask what is documented for the named model on window and encapsulant materials. Both points are part of the technical exchange when a model is quoted, and whether sample quantities for evaluation can be supplied is asked through the same enquiry route.

3535 or 6868 for a new module?

Emitter spacing and board area are among the figures the enquiry states. The 3535 class is the smaller of the catalogue's two format classes, and which family a design takes is confirmed per model in the enquiry exchange. For the larger format, see the 6868 package page.

Array design on the LED35 footprint

The LED35 footprint is one shared nominal class across the family's six models. State the emitter count, the target distance, the board material and the thermal arrangement in the enquiry. Which LED35 model a board design uses, and the thermal arrangement it runs at, are established per model in the enquiry exchange when a package programme is quoted for a new board design.

Working across a six-model family

Six catalogued models inside one format class give a product family options, not automatic interchangeability. Land pattern, reflow behaviour and optical centre are properties of each model; an appliance maker varying the model across product tiers re-checks those three items per model — asking what is documented for each — rather than qualifying the family once and assuming the rest.
