SSP1922 是上海矽朋(Siproin)推出的光电传感器专用器件,面向需要高可靠性、工业级温度范围和低压供电的光电检测应用开发。器件在设计上注重光电信号的稳定获取与系统集成便利性,适合各类嵌入式光电测量、接近/遮挡检测、环境光监测以及工业光学传感场景。
工作电压范围为 2.5V ~ 3.6V,能无缝适配主流 2.8V/3.0V/3.3V 系统;工作温度覆盖 -40℃ ~ +125℃ 的工业级温区,保证在苛刻环境下的长期稳定性。
注:以上为产品定位与基础参数摘要,具体电学性能(例如灵敏度、带宽、输出形式)请参考订货及技术手册中的典型曲线与时序说明。
SSP1922 采用 QFN-32-EP (5x5 mm) 封装,特点包括:
为获得最佳性能,建议在系统设计时注意以下要点:
SSP1922 的行业定位强调在宽温区间内的长期稳定性与重复性。QFN-EP 封装提供了良好的热性能和机械强度,但在实际应用中仍需按器件规格书进行储存与焊接工艺控制,防止潮湿敏感性(MSL)与回流温度对封装可靠性的影响。对关键应用建议执行额外的环境应力筛选与系统级验证。
在选型过程中,如果需要替代器件或实现系统级冗余,可关注同类光电前端产品的接口形式(模拟/数字输出)、带宽、灵敏度以及是否集成 ADC/增益调节等功能。选择时优先考虑与目标系统电压(2.5V~3.6V)与工业温度范围匹配的产品,以减少设计改动。
如需更详细的电气参数、引脚定义、参考电路或布局样板图,可联系厂方获取 SSP1922 的完整数据手册与评估板资料,以便在设计阶段快速完成验证与优化。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
