XL-C4040UGC 为 Xinglight(成兴光)推出的一款侧视贴片发光二极管,封装为 SMD-4P(4.0 × 3.95 mm),采用无色透明透镜,独立二极管结构。发光颜色为翠绿色,峰值波长 520 nm,适用于需要侧向出光、面板指示或光带照明的紧凑型电子产品。
翠绿色波长集中在 520 nm 附近,视觉亮度高、饱和度好。120°的发散角适合宽视野指示或均匀照明。典型 Vf 与额定 If 配合下,器件功耗约 56 mW(2.8 V × 20 mA),仍低于最大 70 mW 额定值。出于稳定性考虑,建议使用限流电阻或恒流驱动。
侧视光学结构要求在 PCB 布局时确保出光方向无遮挡。建议采用与厂方推荐的焊盘尺寸和焊盘过孔布局,以保证热量散逸与稳定焊点。支持标准回流焊工艺,但请参照生产商提供的回流曲线,控制峰值温度与时间。
工作温度范围为 -20 ℃ 至 +85 ℃,适合多数商业级应用。为延长寿命,避免在高温高湿环境长期暴露,并在 SMT 前做好防静电、防潮处理;若厂方提供湿敏等级(MSL),请遵循相应烘烤与储存要求。
若需要侧向均匀绿色指示且空间受限,XL-C4040UGC 提供了高显色与稳定亮度的解决方案。选型时注意确认工作电流、散热条件与贴装方向;若需更高亮度或不同色温,可考虑同系列其他功率/尺寸器件。购买时关注供货包装(侧贴载带)与批次一致性以保证颜色与强度的一致性。
如需进一步的回流曲线、二维封装图或光强分布曲线,可向厂方索取完整规格书与样品测试数据。

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.
