NTC 10D-13(RUILON 瑞隆源)产品概述

一、产品简介

NTC 10D-13 为片式(插件)负温度系数热敏电阻,标称阻值 10 Ω(25℃)。器件工作温度范围宽(-55℃~+200℃),适用于高温、振动和工业环境的温度检测与补偿场合。封装为插件型,脚间距 P = 7.5 mm,便于穿孔安装与后续焊接。

二、主要参数

  • 标称阻值:10 Ω(25℃)
  • B 值(25℃/50℃):2800 K
  • 最大稳态电流(25℃):4 A(极限值)
  • 工作温度:-55℃ ~ +200℃
  • 耗散系数(热耗散常数):15 mW/℃(0.015 W/℃)
  • 热时间常数:1.13 min(≈67.8 s)
  • 封装/脚距:插件,P = 7.5 mm
  • 品牌:RUILON(瑞隆源)

三、特性与优势

  • 宽温区工作能力,适合高温环境及苛刻工况;
  • B 值 2800 K,温度敏感度高,25→50℃ 阻值下降显著,利于温度检测与快速响应;
  • 插件封装、7.5 mm 脚距兼容通用 PCB 布局,便于替换与维修;
  • 热时间常数中等(≈68 s),稳定测量与抗瞬态干扰能力良好;
  • 耐高温、机械强度好,适合工业类传感和补偿场景。

四、电气与热学计算示例

  • 温度与阻值关系常用公式:R(T) = R25 · exp[B·(1/T - 1/T25)],T 单位为 K。
  • 例:25℃→50℃ 时,R50 ≈ 10 Ω · exp[2800·(1/323.15 - 1/298.15)] ≈ 4.86 Ω(约为 25℃ 时的一半)。
  • 自热计算:耗散系数 15 mW/℃ 意味着每升高 1℃ 大约需 15 mW 的功率输入;ΔT = P / 0.015。
    • 若希望自热引起温升 ≤ 5℃,允许功率 P ≤ 75 mW,对应连续电流 I ≤ sqrt(0.075/10) ≈ 86 mA。
    • 因此用于精密温度测量时,应将工作电流控制在几十毫安以下,以避免显著自热误差。
  • 最大稳态电流 4 A 为器件极限特性,短时或特殊场合可参考,但长期工作需综合热耗散与周边散热条件评估。

五、典型应用

  • 温度测量与温度传感器(工业控制、热保护);
  • 温度补偿与电路稳定(放大器、精密元件补偿);
  • 电池温度监控、马达/变压器温度检测;
  • 高温及宽温域电子设备的热管理方案中作为温度敏感元件。

六、安装与使用注意

  • 为降低自热误差,测量回路宜采用恒压低电流或脉冲测量方式;
  • 避免长期靠近热源或强对流环境中无保护安装,必要时采用散热或屏蔽措施;
  • 插件焊接时避免长时间高温直烙,按通用元件焊接规范进行预热与快速完成焊接;
  • 工作环境中应防止腐蚀性气体、强酸碱或长期潮湿,严禁机械过度弯折引脚。

七、选型与采购建议

选型时注意确认阻值公差、线性度及长期漂移等详细资料(上文未列出),如用于精密测量应向厂家索取完整数据手册和温漂曲线。对于需要高连续电流或作为限流元件的应用,应评估实际功耗与散热条件,必要时选择专用的大功率限流 NTC 或增加散热设计。购买时注明型号、封装脚距与温度等级,以保证替换与量产一致性。

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
