SDNT1608X104F3950FTF 为 Sunlord(顺络)出品的高精度小型 NTC 热敏电阻,标准 0603(1608 米制)贴片封装,标称阻值 100 kΩ(25℃),阻值公差 ±1%,B 值(25℃/50℃)3950 K,B 值精度 ±1%。器件设计用于对温度进行精确测量与控制,适配空间受限、需高分辨率温度检测的消费电子、仪表、BMS、HVAC 等场景。
注:尽管器件额定功率为 100 mW,但为减小自热引起的测温误差,通常在测量时限制偏置电流远低于最大稳态电流。例如 100 µA 在 100 kΩ 时对应约 10 V 压降并产生约 1 mW 功率(引起约 1℃ 自热)。
NTC 常用 B 参数关系式: R(T) = R0 * exp[ B * (1/T - 1/T0) ](温度以开尔文 K 为单位) 以 R0 = 100 kΩ(25℃,T0 = 298.15 K)、B = 3950 K 为例:
这些示例有助于选择参考电阻和 ADC 输入范围。

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.
