RL0402E012M300K是瑞隆源(RUILON)针对小型化低电压电路推出的贴片压敏电阻(MOV),核心解决ESD、电源浪涌等过压问题,兼具小封装、低电容、精准保护的特点,适配消费电子、物联网等高密度设计场景。
该器件聚焦超小型终端+高频接口的过压防护,核心目标是:
主要应用于低电压电路的ESD防护、浪涌抑制场景,替代传统大封装压敏电阻,满足小型化设计需求。
基于用户提供的核心参数,结合压敏电阻技术逻辑解析:
指通过1mA直流电流时的器件电压,是保护启动阈值:
器件导通后限制的最高电压(注:若参数存在表述误差,需以原厂 datasheet 为准,正常逻辑下钳位电压应高于压敏电压)。若按用户参数,该值可将过压限制在25V以内,保护后端敏感器件(如MCU、传感器)。
低电容是核心优势:
长期安全工作的直流电压上限,确保电路常态电压不超12V时,器件无额外功耗。
封装尺寸为1.0mm×0.5mm(英制0402/公制1005),是贴片器件最小封装之一,大幅降低PCB占用面积,适配超小型终端的高密度布局。
无引脚SMD封装,支持自动化SMT贴装,生产效率高;焊接可靠性符合IPC-A-610标准,批量生产一致性好。
该器件是低电压电路过压保护的高性价比选择,可有效提升终端产品的可靠性与抗干扰能力。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
