DS18B20+ 是一款数字温度传感器,采用单总线(1-Wire)通信,3 引脚 TO-92 封装,常以散装/袋装方式供应。器件适用温度范围为 -55℃ 到 +125℃,工作电压 3.0V 至 5.5V,品牌信息按需求可见 ADI(亚德诺)/LINEAR。凭借单线通信、多点挂载和片内数字化温度转换,DS18B20+ 适合各种环境温度测量与控制场景。
封装:TO-92 直插式,3 引脚,便于面包板与穿孔板装配。
引脚(面向扁平面、引脚向下时,自左至右):
常规接法建议在 DQ 与 VDD 之间并联一个约 4.7kΩ 的上拉电阻;使用寄生供电模式时,设备由 DQ 和 GND 提供能量,应注意总线时序和负载能力。
适用于空调与暖通(HVAC)系统、工业温度监控、环境监测、家电温控、温度记录器与远程传感节点等场景,尤其在需要多点布置但引脚资源有限的系统中具有明显优势。
DS18B20+ 为成熟器件,市场上有多个厂商和不同封装形式;采购时核对出厂型号、温度等级、封装(TO-92)和供应商资质(如 ADI/LINEAR 或其他正规厂家)。若对热响应速度、封装防护或安装方式有特殊要求,可考虑封装化或表面贴装版本作为替代。

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.
