NTC 10D-20 产品概述

一、产品简介

NTC 10D-20(RUILON 瑞隆源)是一款通用型插件负温度系数热敏电阻,主要用于电源和电子设备的浪涌吸收、过流保护与吸弧灭弧。器件在常温(25℃)时标称阻值为10Ω,采用直插封装,脚距P=10mm,适合批量装配与维修替换。

二、主要技术参数

  • 标称阻值(25℃):10Ω
  • B值(25℃/50℃):2950K
  • 电阻公差:±20%
  • 最大稳态电流(25℃):6A
  • 使用温度范围:-55℃ ~ +200℃
  • 耗散系数(热常数):24 mW/℃(稳定态功耗使器件升高1℃所需功率)
  • 热时间常数:1.88 min(≈113 s)
  • 引脚间距:10 mm(插件)

电阻随温度变化可按标准指数关系近似计算: R(T) = R25 * exp[B*(1/(T+273.15) - 1/298.15)]

三、产品特点

  • 良好的浪涌抑制能力:初始冷阻可有效限制瞬态电流,随通电升温电阻迅速下降,降低功耗与发热。
  • 宽温度适应性:工作温度范围宽(-55℃~+200℃),适应工业级环境。
  • 快速热响应与稳定性:热时间常数约1.88分钟,耗散系数小,适合间歇与持续工作场景。
  • 结构可靠、易于安装:插件封装、10mm脚距,便于手工焊接或波峰焊时替换。
  • 成本效益高:适合大规模电源前端浪涌限制与保护应用。

四、典型应用场景

  • 开关电源和电源适配器的启动浪涌电流限制器(inrush current limiter)。
  • 各类直流电源、充电器、电机驱动器的过流缓冲与保护。
  • 电磁继电器和接触器的吸弧、灭弧保护元件。
  • 家电、LED驱动、电源模块的防浪涌元件。
  • 需要低功耗起始限制且允许电阻随温升下降的场合。

五、安装与使用注意事项

  • 额定最大稳态电流6A为25℃下限制值,实际电流容许度应考虑环境温度、自热升温及散热条件,必要时留有余量。
  • 耗散系数24 mW/℃表示器件在空气中散热性能,若封装或贴近散热不良,温升将增大,可能引起性能偏离或损坏。
  • 不建议将此型号用作高精度温度测量元件(电阻精度±20%)。
  • 虽然器件能耐高温(最高至200℃),但在波峰/回流焊时应避免长时间直接高温暴露,焊接工艺以短时快速焊接为宜。
  • 安装时应避免引脚弯折或机械应力,留有一定间隙以改善散热。
  • 对应电路中若存在多次大能量浪涌,建议配合熔断器或其它防护元件以确保可靠性。

六、选型与替代建议

  • 若需要更低初始电阻或承受更大稳态电流,可选择标称阻值更小或额定电流更高的NTC型号。
  • 若对温度精度要求高,应选用高精度温度传感器或具有更小公差的NTC/RTD。
  • 在高能量浪涌场合,可并联适当的水泥电阻或限流器件以分担能量。

七、包装与订购信息

  • 品牌:RUILON(瑞隆源)
  • 封装形式:插件,脚距P=10mm
  • 常见采购时注意标注:型号(NTC 10D-20)、阻值公差(±20%)、B值(2950K)、最大稳态电流(6A)及应用要求,以便获得合适批次与测试报告。

总结:NTC 10D-20 是一款面向电源浪涌抑制与过流保护的经济型热敏电阻,适合多种工业与家电应用场合。选型时请综合考虑环境温度、散热条件和浪涌能量,以保证长期稳定运行。

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
