LTST-S220TBKT 是 LITEON(台湾光宝)出品的一款蓝色 SMD 指示灯,采用小型表面贴装封装,适合对体积、观看角度和色彩一致性有要求的消费电子与工控应用。下面从性能、封装、应用与设计要点等方面做一份简明、实用的说明,便于工程师在选型与电路设计时参考。
这些参数表明该器件在 20 mA 驱动下能提供中等亮度的蓝色光输出,配合 130° 的大视角非常适合作为面板指示或状态显示用途。
小尺寸 SMD 封装利于高密度 PCB 设计,透明透镜保持光色纯正但对直接视觉刺目的抑制较少,若需柔和光效可在面板上配合扩散罩使用。
总结:LTST-S220TBKT 以小型 SMD 封装、稳定的 468 nm 峰值蓝光与宽视角为主要优势,适合各类指示与显示用途。合理的电流驱动、正确的回流焊工艺与适时的降额设计,能够在体积受限的方案中获得可靠、一致的蓝色光效。若需更详细的回流曲线、典型光电曲线或封装尺寸图,请参考 LITEON 官方规格书。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
