KNTC0603/10KF3950 产品概述
一、产品简介
KNTC0603/10KF3950 是 KUU 品牌的高精度贴片负温度系数(NTC)热敏电阻，标准0603封装（1.6mm × 0.8mm × 0.8mm）。标称阻值为 10 kΩ（25℃），电阻精度 ±1%，B 值（25℃/50℃）3950 K，B 值精度 ±1%。器件专为精密温度测量与温度补偿设计，尺寸小、响应快且易于表面贴装生产线使用。
二、主要电气与热参数
- 阻值（25℃）：10 kΩ（±1%）
- B 值（25℃/50℃）：3950 K（±1%）
- 额定功率：100 mW
- 热耗散系数：1 mW/℃（典型）
- 热时间常数：5 s
- 最大稳态电流（25℃）：310 μA（为限制自加热误差而给出的推荐稳态工作电流）
- 工作温度范围：-40℃ ~ +125℃
注：虽然器件额定耗散可达 100 mW，但为保证测温精度并避免自加热引起的读数偏差，通常建议稳态工作电流不超过 310 μA（对应电压约 3.1 V，耗散功率约 0.96 mW）。
三、温度-电阻关系与计算
NTC 的阻值随温度按 B 值关系变化，常用公式： R(T) = R25 * exp[B * (1/(T+273.15) - 1/(25+273.15))] 其中 R25 为 25℃ 时阻值，B 为标称 B 值，T 为摄氏温度。该公式便于在测温电路中实现线性化与标定。
四、典型应用场景
- 便携式设备温度监测（电池、充电管理）
- 家电与消费电子温度保护与控制
- 温度补偿电路（传感器、振荡器等）
- 工业控制与环境监测（要求小体积、高精度场合）
五、封装与装配建议
- 采用标准 SMD 回流焊工艺，适配无铅回流曲线（请参考焊料与 PCB 工艺规范）。
- 为获得最快响应与最低误差，温敏点应靠近被测对象并确保良好热耦合；若需隔热以减少 PCB 热干扰，可适当减少周围铜箔。
- 避免在测温区域产生强散热源或大电流迹线通过器件附近，以减小自加热与温漂影响。
KNTC0603/10KF3950 以其高精度（±1% 阻值与 B 值）、小尺寸与快速热响应，适合对温度测量精度与体积有严格要求的现代电子产品。

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.
