SDNT2012X103F3450FTF 是顺络(Sunlord)推出的一款高精度表面贴装型 NTC 热敏电阻,封装尺寸为 0805(国际封装代码,对应常见印制板焊盘)。器件标称阻值 10 kΩ,电阻精度 ±1%,B 值(25℃/50℃)为 3450 K,B 值精度 ±1%。该型号定位为温度检测与温度补偿场景下的高稳定性、小体积方案,适合对测温精度和响应速度有较高要求的便携式与工业电子设备。
注:在最大稳态电流 400 µA(25℃)条件下,器件在 10 kΩ 时的耗散功率约为 1.6 mW,对应的自热温升约为 1.6 mW / (2 mW/℃) ≈ 0.8℃;若按额定功率 200 mW 计算,温升将非常显著(≈100℃),因此测温应用中应避免接近额定功率工作点。
总结:SDNT2012X103F3450FTF 以其高精度(±1% 阻值与 B 值)、小型化封装与快速热响应,适用于各类对温度测量精度与稳定性有较高要求的便携与工业电子产品。在实际电路设计中,应优先考虑限制工作功率以降低自热影响,并采用合适的焊接与布线方法以保证测量准确性与长期可靠性。

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.
