RLM102-301M是RUILON(瑞隆源)推出的一款表面贴装(SMD)压敏电阻,专为电子电路过压防护设计,可有效抑制浪涌电流、尖峰电压对敏感元器件的损害,兼具小体积、高可靠性与宽温适应性,适用于多领域电子设备的防护场景。
该产品属于氧化锌压敏电阻范畴,核心作用是在电路遭遇异常过压时(如雷击感应、电源瞬变、静电放电等),快速由高阻态转为低阻态,将过压钳位至安全范围,同时泄放浪涌能量,保护后端IC、半导体器件、传感器等核心元件不被损坏。其定位覆盖消费电子、工业控制、通信设备等领域的通用过压防护需求,尤其适合对尺寸敏感的小型化设备。
标称击穿电压(V₁mA)为300V,精度±20%,实际工作范围为240V~360V(1mA测试电流下),满足多数低压电路的过压防护阈值要求,避免因电压波动误触发或防护不足。
最大浪涌电流(8/20μs标准波形)为1kA,可承受单次或多次(额定次数内)浪涌冲击,有效应对常见电源浪涌、雷击感应等场景。
常态电容仅1pF,属于低电容型压敏电阻,对高频信号传输影响极小,适合射频电路、高速数据接口等对电容敏感的应用场景,避免信号衰减或失真。
常态绝缘电阻≥100MΩ(25℃、100V DC测试),保证电路正常工作时无漏电,不影响设备功耗与稳定性。
采用SMD封装,尺寸为φ2.7mm(直径)×5mm(长度),属于小型化表面贴装规格,适配标准SMT贴装工艺,可直接集成于PCB板,无需额外插件空间,显著节省设备内部布局面积,适合手机、智能穿戴、小型工业模块等紧凑设计产品。
工作温度范围为**-45℃~+85℃**,覆盖工业级与消费电子典型温宽:
RUILON(瑞隆源)是国内专注过压保护器件的专业厂商,RLM102-301M经过多项可靠性测试:
该产品通过平衡防护性能、尺寸与成本,成为通用电子设备过压防护的高性价比选择,可满足多数中端应用场景的防护需求。

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.
