14D181K 产品概述
一、产品简介
RUILON（瑞隆源）14D181K 为径向引线型金属氧化物压敏电阻（MOV），面向直流/交流中低压浪涌抑制场景。典型压敏电压（V1mA）198V，钳位电压300V，工作电压：直流150V、交流115V；峰值浪涌电流可达4.5kA，单次能量吸收能力约57J。器件静态电容约1.03nF（1kHz），静态功耗600mW，适合电源输入侧、设备内部直流总线及保护并联方案。
二、主要电气参数
- 压敏电压（V1mA）：198V
- 钳位电压（Ipk对应）：300V
- 工作电压（DC）：150V
- 工作电压（AC rms）：115V
- 峰值浪涌电流（Ipk）：4.5kA
- 能量吸收（典型）：57J
- 静态电容：1.03nF @ 1kHz
- 最大静态功率耗散：600mW
三、器件特性与优势
- 高能量吸收能力与大电流冲击耐受，适合应对雷击和开关过电压瞬变；
- 钳位电压相对稳定，能有效限制被保护侧电压峰值；
- 较低静态电容，适用于对电容敏感的信号/通信附近电源；
- 径向引线封装便于手工焊接与自动插件，适合批量生产与维修替换。
四、典型应用场景
- 工业电源输入端浪涌保护（SMPS前端、整流桥后直流母线）；
- 通信设备、电信电源和基站辅助保护；
- 家电、电动工具与照明驱动电路的过压防护；
- UPS、逆变器及光伏逆变器的输入旁路保护。
五、选型与使用注意
- 确认系统工作电压与器件工作电压匹配（DC≤150V，AC rms≤115V）；
- 考虑浪涌能量和冲击波形（能量57J与Ipk 4.5kA为典型值，实际可靠性受浪涌次数和温度影响）；
- 当并联使用多个MOV时，应注意均流与热管理；
- 对静态电容敏感的应用需评估1.03nF带来的影响，必要时选用低电容方案。
六、安装与可靠性建议
- 保持良好通风与散热条件，避免长期在高温高湿环境下工作；
- 焊接时遵循厂商推荐的回流/波峰温度曲线并避免过长高温暴露；
- 建议在PCB布局中为MOV留足爬电距离和绝缘间隙，远离敏感模拟电路；
- 对关键应用建议配置熔断器或热断路保护，防止MOV击穿后导致的次生故障。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
