FNTC0603X103F3380FB 是长江微电(cjiang)推出的一款高精度表面贴装型 NTC 温度敏感电阻(负温度系数热敏电阻),采用0603(1.6 × 0.8 × 0.8 mm)封装,阻值标称为 10 kΩ(25℃)。本器件针对体积受限的高密度 SMT 应用,提供 ±1% 阻值公差与 ±1% B 值精度,适合需要较高测温精度与快速热响应的电子设备。
热敏电阻阻值随温度 T(K)变化可以用 R(T) = R25 · exp[B · (1/T - 1/T25)] 近似计算(T25 = 298.15 K)。下面为基于标称值的近似结果,仅供设计参考:

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.
