DS18S20 是一款基于 1-Wire 总线的寄生电源数字温度传感器,适合用于恒温控制与温度监测场景。该器件工作电压 3.0V–5.5V,支持寄生供电模式,无需独立电源线即可工作;并且具有片内非易失参数存储与温度阈值监测功能,便于系统中实现本地报警和长期参数保存。常见品牌/供应渠道包括 ADI(亚德诺)/LINEAR,产品包装可选 TO-92 封装与卷带(T&R)出货方式,便于批量 SMT 或插件线束组装。
DS18S20 采用 1-Wire 协议,每片器件具有唯一 64-bit ROM 代码,支持多点挂接与设备寻址。寄生电源模式下器件利用数据线存储电荷完成转换,注意在温度转换期间需对总线提供强上拉(或使用外部电源)以保证可靠供电与测量完成。通信需注意时序与 CRC 校验以确保数据完整性。
型号标识常见为 DS18S20,常见出货封装为 TO-92(穿孔)及卷带(T&R)以便自动化贴装或大批量供货。订购时请确认是否为带 T&R 的卷带包装规格、批量与散装差异,以及所需的温度等级与校准证书。

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.
