TDK NTCG064BF473FTBX 热敏电阻(NTC)产品概述

TDK NTCG064BF473FTBX是一款采用0201贴片封装的负温度系数热敏电阻(NTC),具备高精度、宽温范围、小尺寸等核心特性,广泛适用于各类需要温度监测与补偿的电子设备中,尤其适合对空间和精度要求严格的场景。

一、核心基本参数

该产品的基础参数明确且稳定,可支撑多场景温度应用:

  • 阻值与精度:标称阻值47kΩ(代码473,即47×10³Ω),电阻精度达±1%,有效降低温度测量的基础误差;
  • 工作温度范围:-40℃至+125℃,覆盖消费电子、汽车电子及工业控制的典型环境温度区间;
  • B值精度:B值(温度系数关键参数)精度为±1%,确保不同温度下阻值变化规律的一致性。

二、B值特性与温度相关性

B值是NTC热敏电阻的核心特性,反映电阻随温度变化的灵敏度。TDK NTCG064BF473FTBX在不同温度区间的B值如下:

温度区间(T1/T2) B值(K) 25℃/50℃ 4050 25℃/75℃ 4098 25℃/85℃ 4114 25℃/100℃ 4137

从数据可见,B值随温度升高略有上升,整体变化平稳,说明产品在宽温范围内的温度响应一致性良好,可满足高精度测温需求(如电池管理系统的温度补偿)。

三、电气与功率性能

产品电气性能兼顾精度与可靠性:

  • 额定功率:100mW,适配多数低压电路的功率需求;
  • 最大稳态电流:25℃环境下为140μA(由P=I²R推导:I=√(0.1W/47000Ω)≈140μA),明确安全工作电流范围;
  • 耗散系数:1mW/℃,即每升高1℃自身消耗1mW功率。该参数极小,自身发热对环境温度测量的干扰可忽略,适合高精度测温(如可穿戴设备的体温监测)。

四、机械封装与尺寸

采用0201贴片封装,具体尺寸为:

  • 长度:0.6mm;
  • 宽度:0.3mm;
  • 高度:0.3mm。

小尺寸设计可轻松集成于高密度PCB,适配便携式电子设备(如智能手机、智能手环)、小型化工业传感器等对空间要求严格的场景;贴片封装便于自动化贴装,提升生产效率。

五、典型应用场景

结合参数特性,该产品的典型应用包括:

  1. 消费电子:智能手机/平板的电池温度监测(防止过充过放)、充电器/电源适配器的温度保护;
  2. 汽车电子:车载空调温度控制、电动车BMS的温度监测、车灯/传感器的温度补偿;
  3. 可穿戴设备:智能手环/手表的环境温度/体温监测(小封装适配人体佩戴);
  4. 工业控制:小型仪器仪表的温度测量、电机/变频器的温度保护、工业传感器的温度补偿;
  5. 医疗电子:小型医疗设备(如体温计、血糖仪)的温度校准(宽温与高精度适配医疗场景)。

六、产品优势与特点

相较于普通NTC热敏电阻,该产品具备以下核心优势:

  • 高精度:电阻±1%、B值±1%精度,减少测温误差,提升系统可靠性;
  • 宽温适应性:-40℃至+125℃覆盖极端环境(如汽车低温启动、工业高温工况);
  • 小尺寸高集成:0201封装适配高密度设计,满足小型化设备需求;
  • 稳定响应:不同温度区间B值变化平稳,确保测温一致性;
  • 低干扰:1mW/℃耗散系数,自身发热对测量影响可忽略;
  • TDK品质:知名品牌保障,可靠性与一致性经过严格验证,适合批量应用。

综上,TDK NTCG064BF473FTBX是一款性能均衡、适配多场景的高精度NTC热敏电阻,可满足消费电子、汽车、工业等领域对温度监测与补偿的需求。

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
