FNTC0805X104F4250FB是长江微电(CJ)推出的0805封装高精度NTC热敏电阻,核心参数为25℃标称阻值100kΩ、25/50℃B值4250K,主打宽温区、高一致性的温度检测与补偿应用。其典型落地场景覆盖多领域:
25℃标称阻值为100kΩ(104),电阻精度±1%——这一精度远高于普通NTC的±5%,能直接提升温度检测准确性,减少后续校准成本,适合对温度精度要求苛刻的场景(如医疗设备温度监测)。
覆盖**-40℃~+125℃**,适配从北方冬季户外(-40℃)到工业烤箱(125℃)的全场景需求,无需额外考虑温区适配问题。
热时间常数5s——表示温度变化到最终值的63.2%所需时间,属于较快响应速度,可满足实时过温报警(如电池过温10秒内触发保护)等场景。
在-40℃至125℃范围内,阻值与B值的波动被严格控制在精度范围内,长期工作无明显漂移。经测试,1000小时高温老化后,阻值变化率小于0.5%,适合24小时不间断运行的设备。
采用成熟的NTC陶瓷材料与环氧树脂封装工艺,能承受温度循环(-40℃~125℃循环500次)、湿度(85℃/85%RH环境1000小时)等应力,符合工业级可靠性要求。
封装类型为0805(英制尺寸,对应公制2012),具体尺寸:
长江微电(CJ)作为国内被动元器件头部厂商,FNTC0805X104F4250FB继承了品牌的高一致性与可靠性:
该产品凭借高精度、宽温区、小型化等优势,成为消费电子、汽车电子、工业控制等领域温度检测与补偿的优选方案。

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.
