KNTC0603/100KF3950 产品概述

一、产品简介

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。

二、主要技术参数

  • 阻值(25℃):100 kΩ ±1%
  • B 值(25℃/50℃):3950 K ±1%
  • 功率额定:100 mW
  • 最大稳态电流(25℃):100 μA(建议测量电流远低于此值以降低自加热误差)
  • 耗散系数(热耗散):1 mW/℃
  • 热时间常数:5 s(自由空气,典型值)
  • 工作温度范围:-40℃ ~ +125℃
  • 尺寸(封装 0603):长 1.6 mm × 宽 0.8 mm × 高 0.8 mm
  • 封装:0603 SMD,品牌:KUU

三、温度–阻值关系与计算示例

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。

四、特点与优势

  • 高阻值(100 kΩ)适合高阻输入、低功耗测量场景;
  • 精度高:阻值与 B 值均为 ±1%,利于温度测量与补偿的可重复性;
  • 小型化 0603 封装,易于高密度 PCB 布局与自动贴片生产;
  • 响应快(热时间常数 5 s),适合一般环境温度监测;
  • 可靠的工作温度范围满足工业级应用需求。

五、典型应用

  • 便携式与可穿戴设备温度检测;
  • 电池组与电源管理温度补偿;
  • PCB 上温度监测与热保护;
  • 温度敏感的传感器补偿电路与桥式测量网络;
  • 物联网节点、家电及医疗类电子装置。

六、安装与使用建议

  • 建议采用标准 0603 回流焊工艺,遵循 PCB 制造商与焊料供应商的回流曲线;
  • 测量时尽量使用低测量电流(例如 1–10 μA),以减小自加热引起的温升误差;
  • 耗散系数约 1 mW/℃,若电路中功耗较高,应评估自热造成的温度偏差;
  • 避免在焊接或组装过程中对器件施加过大机械应力或弯曲 PCB;
  • 在需要高精度温度测量的场合,可在电路中加入校准系数或二点校准补偿。

七、可靠性与选型提示

  • 本件适用于对尺寸、功耗和精度有综合需求的设计;若需要更快速响应或更大功率承受能力,请选择更大封装或专用温度传感器;
  • 在选型时注意测量链路的输入阻抗与最大稳态电流限制,确保实际工作点不会引入过大自加热;
  • 如需批量采购或特殊封装、出货形式(盘带/卷盘)信息,请联系 KUU 或授权分销商获取最新资料与样品。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
