NTC 1.5D-15 产品概述

一、产品简介

NTC 1.5D-15 是RUILON(瑞隆源)推出的一款片式敏感电阻(负温度系数热敏电阻),为插件(Through‑hole)封装,脚间距(P)为7.5mm。标称阻值为1.5Ω(25℃),在25℃环境下最大稳态电流为8A。器件工作温度范围宽,可在-55℃至+200℃间可靠工作,适用于需要大电流启动抑制或温度敏感保护的场合。

二、主要规格参数

  • 品牌:RUILON(瑞隆源)
  • 型号示例:NTC 1.5D-15
  • 标称阻值(25℃):1.5Ω
  • 最大稳态电流(25℃):8A
  • 工作温度范围:-55℃ ~ +200℃
  • 封装形式:插件(片式/盘形),引脚间距 P = 7.5mm
  • 用途分类:NTC 热敏电阻 / 启动限流 / 温度感应/保护元件

(注:具体型号其它参数如B值、自恢复电流脉冲承受能力、动态热阻等,请参见厂方详细数据手册或询价时索取完整规格书。)

三、核心特性与优势

  • 高电流能力:25℃下最大稳态电流可达8A,适用于中大电流场合的浪涌限制与软启动应用。
  • 宽温度适应性:-55℃至+200℃的工作温度范围,保证在极端环境下仍能稳定工作,适合工业与高温环境。
  • 插件封装,便于手工或自动化插件安装,脚距7.5mm 兼容常见板孔布局,机械强度好,便于更换维护。
  • 阻值低、响应快:1.5Ω 初始阻值在通电瞬间能有效限制浪涌电流,通电后自热使阻值迅速下降,减小功耗损耗。

四、典型应用场景

  • 开关电源和逆变器的浪涌电流限制(软启动)
  • 电机驱动与压缩机启动时的电流抑制
  • 电池充电与保护电路,防止充电初期的冲击电流
  • 大功率 LED 驱动、照明电源的启动保护
  • 工业控制设备、家电产品、电动工具等需承受启动冲击的场合
  • 温度检测与过温保护(作为温度敏感元件配合测量电阻变化)

五、热与电性能注意事项

  • 自热效应:NTC 在通电后会因自身功耗升温,阻值随温度下降(负温度系数),稳态电流与阻值会发生显著变化。设计时应考虑器件从冷态到稳态的阻值变化曲线,以确保启动期与稳态期均在安全工作区。
  • 温度升高影响允许电流:在高环境温度或受限散热条件下,器件允许的稳态电流会下降,需留有裕量或采取散热措施(如加装散热片、改善通风)。
  • 瞬态脉冲承受:虽具有浪涌抑制能力,但对极短时间、大幅超载的脉冲仍有承受极限,必要时与保险丝或浪涌抑制器件配合使用。

六、安装、焊接与使用建议

  • 焊接工艺:采用合适的焊接工艺以减少对元件的热损伤。尽量缩短加热时间并采用预热工艺,避免长时间高温直接作用于器件引脚和体部。具体焊接温度/时间参考供应商的推荐。
  • 机械应力:插件时避免对引脚施加过大弯曲或扭曲力,防止引脚疲劳断裂或内部连接松动。
  • 布局建议:保持器件与热敏元件及发热体之间适当距离,必要时提供独立散热路径;避免与温度敏感的其它器件紧邻。
  • 存储与搬运:避免潮湿、强腐蚀气体环境存放,存放温湿度应符合电子元件常规要求。

七、可靠性与测试

  • 常规测试包括:直流阻值测量(25℃)、高温/低温循环试验、热冲击、稳态电流承受试验、浪涌脉冲试验及绝缘/耐压测试(如有必要)。
  • 建议在样机阶段进行系统级测试,验证在实际工作电压、电流、环境温度下的稳态与瞬态性能,确保长期可靠性。

八、选型建议与采购信息

  • 选型时优先确认:标称阻值(25℃)、最大稳态电流、工作环境温度、封装形式(插件脚距),以及是否需要更低或更高阻值/电流规格的型号。
  • 若系统含高环境温度或连续大电流工作,应选择额定电流有裕度的型号或配合散热方案。
  • 采购与技术细节请联系RUILON(瑞隆源)或其授权经销商获取完整数据手册、样品及批量供货信息。

九、安全与维护要点

  • 使用时须遵照额定参数,过载或长期超温会导致性能退化或失效。
  • 建议与适配保护元件(如慢断型保险丝、热保护开关)配合使用,提升系统安全性。
  • 定期检查焊点和外观,无异常时方可继续使用;发生外观破损、过热变色或阻值异常应及时更换。

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
