TDK NTCG104LH223HT1 NTC热敏电阻产品概述

TDK NTCG104LH223HT1是一款针对小型化、高精度温度传感需求设计的负温度系数(NTC)热敏电阻,采用0402封装,具备稳定的温度-阻值特性与宽工作温度范围,适用于消费电子、汽车电子、工业控制等多领域的温度监测场景。

一、核心电气参数

该热敏电阻的核心电气指标直接决定了其适用场景,关键参数如下:

  • 标称阻值:22kΩ(25℃环境下,精度±3%),属于中阻值NTC范畴,可平衡信号强度与功耗;
  • 额定功率:100mW(25℃),满足低功耗电路的温度监测需求,避免过热;
  • 最大稳态电流:210μA(25℃),结合22kΩ阻值计算,电流与功率参数匹配,防止过流损坏;
  • 耗散系数:1mW/℃,表示每升高1℃需消耗1mW功率,反映热响应效率,可用于温度补偿设计。

二、温度特性与B值参数

NTC热敏电阻的核心特性是阻值随温度升高而降低,B值(温度系数)是描述其温度-阻值关系的关键指标。TDK NTCG104LH223HT1的B值特性如下:

  • 以25℃为基准温度,不同温度区间的B值(精度±3%):
    • 25℃/50℃:4485K;
    • 25℃/75℃:4533K;
    • 25℃/85℃:4550K;
    • 25℃/100℃:4573K;
  • 工作温度范围:-40℃至+125℃,覆盖低温环境(如寒冷地区设备)到高温场景(如汽车发动机舱、工业设备);
  • 阻值随温度变化的线性度良好,B值精度稳定,确保温度监测的准确性。

三、封装与物理尺寸

该产品采用0402封装(公制尺寸1mm×0.5mm×0.5mm),是小型化电子设备的主流封装形式,具备以下优势:

  • 体积小巧:长度1mm、宽度0.5mm、高度0.5mm,可集成到可穿戴设备、智能手机、小型传感器模块等紧凑空间;
  • 贴片式设计:兼容自动化贴装工艺,适合大规模量产,降低生产制造成本;
  • 封装可靠性:TDK的封装工艺确保产品在宽温度范围和振动环境下稳定,减少虚焊、脱落风险。

四、典型应用场景

TDK NTCG104LH223HT1凭借小尺寸、宽温域、高精度的特性,广泛应用于以下领域:

  1. 消费电子:智能手机、平板电脑的电池温度监测(防止过充过放)、CPU/GPU温度控制(避免过热降频);
  2. 汽车电子:车载空调温度调节、电池管理系统(BMS)温度传感、发动机舱关键部件温度监测;
  3. 工业控制:小型工业传感器、自动化设备的环境温度监测、电机绕组温度保护;
  4. 可穿戴设备:智能手表、手环的体温监测、环境温度记录;
  5. 家电产品:冰箱、空调的温度控制模块、热水器温度传感。

五、可靠性与环境适应性

该产品的可靠性设计满足多场景需求:

  • 宽温域可靠性:-40℃至+125℃的工作范围,适应极端气候条件下的设备运行;
  • 精度稳定性:阻值±3%、B值±3%的精度,长期使用中特性漂移小;
  • 抗振动性:0402封装的贴片结构,结合TDK工艺,可承受汽车、工业等振动环境;
  • 低功耗:100mW额定功率,适合电池供电的便携设备,延长续航时间。

总结而言,TDK NTCG104LH223HT1是一款高性价比的小型化NTC热敏电阻,兼顾精度、尺寸、温域与可靠性,可满足从消费电子到汽车电子等多领域的温度传感需求,是小型化设备温度监测的理想选择。

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
