KNTC0603/100KF3950 是 KUU 品牌的一款微型贴片负温度系数热敏电阻(NTC),采用 0603 封装,专为体积受限且要求高精度温度测量或补偿的电子系统设计。器件阻值为 100 kΩ(25℃),阻值公差 ±1%,B 值(25℃/50℃)3950 K,B 值精度 ±1%,适用于工业级与消费类多种场景。
NTC 的阻值可用 B 参数方程描述:
R(T) = R25 × exp[B × (1/T − 1/T25)],其中 T 以开尔文(K)计。
以本件为例,计算 50℃ 时的阻值:
T25 = 298.15 K,T50 = 323.15 K,B = 3950 K,得 R(50℃) ≈ 100k × exp[3950×(1/323.15−1/298.15)] ≈ 35.8 kΩ。
该公式便于在电路中进行温度换算或仿真。

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.
