NTC 5D-11 产品概述

一、产品简介

RUILON(瑞隆源)NTC 5D-11 为负温度系数热敏电阻(NTC),标称阻值 5Ω(25℃),设计用于交流/直流电源的涌流限制与过流保护。典型应用为开机浪涌抑制、吸弧/防打火、电源启动限流以及作为过流保护和浪涌吸收组件,广泛用于电源适配器、照明镇流器、电动机驱动、变压器和家电等场合。

二、主要参数

  • 阻值:5Ω(在 25℃ 下标称值)
  • 最大稳态电流(25℃):4A
  • 工作温度范围:-55℃ ~ +200℃
  • 引脚间距(封装):7.5mm(插件,P=7.5mm)
  • 品牌:RUILON(瑞隆源)
    该器件属于低功耗、通用型电源NTC,适合需要中等涌流抑制且空间受限的应用。

三、特性与优点

  • 负温度系数:随电流加大或温升,阻值迅速下降,从而降低功耗和压降。
  • 良好的热循环境稳定性:在 -55℃ 至 +200℃ 范围内保持机械与电气性能。
  • 插件式封装,7.5mm 引脚间距便于安装和更换,适合手工或波峰焊接组装。
  • 快速抑制开机电流尖峰,延长系统中其他元件(如保险丝、开关电源)的寿命。

四、应用场景

适用于电源开关启动限流、浪涌吸收、吸弧与防打火、灯具镇流、充电器、家电控制板、工业控制电源等需抑制瞬态大电流或保护电路免受启动浪涌冲击的场合。

五、选型与使用建议

  • 按最大稳态电流(4A)选择适配器件,并考虑连续工作时的自热和散热条件;若实际工作电流接近或超过标称值,应选用更高规格元件或并联使用并配合熔断保护。
  • 考虑环境温度与通风:高环境温度会降低限制效果并可能导致热老化,建议在良好散热条件下工作。
  • 对于频繁开关或重复冲击场合,评估热循环寿命与阻值漂移,必要时选用更耐冲击的型号。

六、安装与注意事项

  • 插件安装时避免过度弯曲引脚,焊接温度与时间应控制在推荐值内以防基体受损。
  • 存储时避免潮湿、强酸碱环境及机械冲击;长期储存前应进行绝缘和阻值检验。

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
