FNTC0402X103F3380FB 产品概述
一、产品简介
FNTC0402X103F3380FB 是长江微电（cjiang）推出的一款高精度贴片热敏电阻（NTC），标称阻值 10kΩ，封装为 0402（1.0mm × 0.5mm × 0.5mm）。该元件适用于空间受限的消费类、工业和便携式电子温度检测与补偿场合。
二、主要电气与热参数
- 阻值：10kΩ（25℃ 标称）
- 电阻精度：±1%
- B 值(25℃/50℃)：3380K，B 值(25℃/85℃)：3435K，B 值精度：±1%
- 功率额定：100mW；耗散系数：1mW/℃；最大稳态电流（25℃）：310μA
- 热时间常数：3s；工作温度范围：-40℃ ~ +125℃
三、性能特性与应用要点
- 高精度：±1% 阻值与 ±1% B 值允许在温度测量与补偿中实现较小的系统误差。
- 小型化：0402 小封装适合 PCB 密集布线、移动设备与 IoT 终端。
- 自热限制：额定功率与耗散系数意味着在设计测量电路时应限制通过器件的电流（25℃ 最大稳态电流 310μA），以避免自热引入测量偏差。
- 响应速度：热时间常数 3s 表明在多数慢变温环境下响应充分，但用于快速温变检测时需考虑延迟。
四、使用与布局建议
- 测量电路常用恒流源或上拉/下拉分压方式，推荐计算自热影响并选取合适的检测电流（远低于 310μA 为宜）。
- 布局时保证热源与器件之间的隔离或使用热桥以获得真实环境温度；若用于板上温度控制器，应靠近测温点布置。
- 采用标准 0402 回流焊工艺，注意温度曲线与焊接次数限制，避免热冲击导致参数漂移。
五、典型应用
温度测量（环境温度、传感点）、电池管理温度补偿、RTC/晶振温度校准、功率器件温度监控与温度补偿网络等。
FNTC0402X103F3380FB 以其高精度、微型封装与良好的温度特性，适合在受限空间内实现可靠的温度感测与补偿解决方案。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
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.
