14D151K 产品概述

一、产品简介

14D151K(品牌:RUILON/瑞隆源)是一款通用型金属氧化物压敏电阻(MOV),采用插件封装,间距P=7.5mm,适用于交流或直流电源端的过电压保护。该器件在遭遇雷击、电源浪涌或开关瞬变时能快速钳位电压,吸收冲击能量,保护后端电子设备免受瞬态过电压损坏。

二、主要技术参数

  • 压敏电压(Vr,典型):165V
  • 钳位电压(在指定浪涌下):250V
  • 工作电压(DC):125V
  • 工作电压(AC,有效值):95V
  • 峰值浪涌电流(8/20μs):6kA
  • 吸收能量:56J(按标准脉冲能量计)
  • 静态电容:3nF @1kHz
  • 静态功率(持续功耗):600mW
  • 封装形式:插件(引脚间距 P = 7.5mm)

三、产品特点与优势

  • 高浪涌能力:6kA 峰值浪涌电流与 56J 吸收能量,可应对典型雷电及开关浪涌事件。
  • 有效钳位:在浪涌作用下钳位电压约250V,降低后端设备承受的瞬态电压。
  • 通用工作电压:DC125V / AC95V 适合多数直流或低压交流供电系统。
  • 低静态功耗与合适电容值:600mW 的静态功率与 3nF 电容,在多数电源滤波场景下对信号影响可控。
  • 插件封装易于维修与替换,适合电源板、配电箱等场合的现场维护。

四、典型应用场景

  • 工业电源防雷与浪涌保护(配电柜、工业控制电源)。
  • 家用电器与消费电子(电视、电源适配器、充电设备)。
  • 通信设备电源保护(交换机、路由器、电源模块)。
  • 直流供电系统与逆变器的输入侧防护。

五、选型与使用建议

  • 持续工作电压不得超过标称工作电压(DC125V / AC95V),为保证长期可靠性,建议实际工作电压留有余量(例如不超过额定的80%范围)。
  • 压敏电阻用于吸收瞬态能量,不宜作为连续限流或稳压元件;频繁大能量冲击会导致性能退化,应配合熔断器或串联限流元件使用。
  • 在对高频信号敏感的电路中,需考虑3nF的寄生电容对信号完整性的影响,必要时选择更低电容或采取滤波/隔离措施。
  • 设计板上布局时,保持与敏感器件的安全距离和良好散热路径,避免局部过热影响寿命。

六、封装与机械特性

插件形式,典型引脚间距 P = 7.5mm,便于通过孔焊接或手工更换。具体外形尺寸、引脚直径与间距请参考厂家机械图纸以便布局和固定。

七、品质与采购注意

RUILON(瑞隆源)品牌提供的14D151K适用于广泛工业与民用场景。采购时请确认:产品批次、产品测试报告(浪涌试验、耐压试验)以及是否满足所需的行业认证。对关键应用建议索取样品并进行实际系统验证。

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
