XL-304UBD(成兴光 Xinglight)为直插式 3mm 圆形指示灯,蓝色透镜、蓝色发光,峰值波长 460nm(光谱范围 455–465nm)。典型正向电压 Vf=3.4V,额定正向电流 If=20mA,单颗功率约 70mW,发光强度约 1500mcd。封装为插件(D=3mm),产品标称为“长脚”,适合通孔安装与手工/波峰焊接工艺。
LED 必须限流驱动。限流电阻计算公式:R = (Vcc − Vf) / If。举例:
可采用 PWM 调光,推荐 PWM 频率 >100Hz 以避免肉眼可见闪烁;占空比控制平均亮度。连续使用请勿超过额定 20mA,短脉冲峰值电流需遵循厂方限制或进行可靠性验证。
适用于面板指示、状态指示灯、消费电子、仪表、控制面板、玩具、教育产品及通用信号提示等需要蓝色指示的场合。
如需进一步的电气曲线、光强-电流关系、光谱分布或大批量采购规格书与可靠性报告,请提供使用场景与测试要求,我可协助准备更详细的技术资料。

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.
