RL4032A561K 产品概述
一、产品简介
RL4032A561K 是 RUILON（瑞隆源）推出的一款表面贴装型压敏电阻（MOV），采用4032塑料SMD封装，设计用于对电源与信号端口的浪涌、雷击和瞬态过压进行吸收和钳位保护。器件电气性能等同于引脚式型号，便于在SMT工艺中替代传统插件型浪涌保护元件。
二、主要参数（典型值）
- 压敏电压（V）：616 V
- 钳位电压（V）：930 V
- 工作电压（DC）：450 V
- 工作电压（AC）：350 V
- 峰值浪涌电流（8/20 μs）：2.5 kA
- 能量吸收能力（10/1000 μs）：69 J
- 静态电容：180 pF @ 1 kHz, 1 V
- 封装：4032（SMD）
- 标准与可焊性：RoHS 符合、AEC-Q101 认证、适用于无铅焊接
- 附件：提供 Pspice 仿真模型
三、典型应用场景
- 电信系统电源总线与直流母线保护
- LED 驱动电源与照明系统的过压/浪涌防护
- 工业电源接口、逆变器输入端的浪涌吸收
- 需要SMD化、可靠性要求高的汽车电子和通信设备（符合 AEC-Q101）
四、优势与设计要点
- SMD 4032 封装，便于自动化贴装与回流焊接，节省PCB空间；
- 高频静态电容值约180 pF，适配多数电源与照明驱动，但在高精度信号路径需考虑耦合影响；
- 高能量吸收（69 J）与2.5 kA 峰值能力，适合中强度雷击与开关瞬变工况；
- 钳位电压控制良好，可在过压时限制系统电压在安全范围；
- 提供 Pspice 模型，方便在系统级设计时进行瞬态仿真与验证。
五、布局与使用建议
- 将器件尽可能靠近被保护端（输入端/连接器），引线最短以降低感抗；
- 对于对静态电容敏感的模拟或通信线路，评估180 pF 的耦合影响，必要时采用低容或串联阻抗隔离；
- 推荐按制造商提供的回流焊工艺曲线进行无铅焊接，避免超温或长时间处于高温区；
- 储运及焊接前避免受潮与静电冲击，必要时按常规防静电措施处理。
六、订购信息与支持
订购型号：RL4032A561K（RUILON 瑞隆源）
可向供应商索取详细数据手册、典型脉冲测试曲线以及 Pspice 模型，以便在系统设计和可靠性验证阶段进行精确评估。
如需根据具体应用（如更高能量或更低电容要求）推荐替代型号或并联/串联使用建议，可提供应用环境参数后进行选型支持。

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.
