RLM102-301M 压敏电阻产品概述

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。

一、产品定位与核心用途

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。

二、关键技术参数解析

1. 击穿电压与精度

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。

2. 浪涌电流能力

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。

3. 电容特性

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。

4. 绝缘电阻

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。

三、封装与尺寸特性

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。

四、环境适应性

工作温度范围为**-45℃~+85℃**,覆盖工业级与消费电子典型温宽:

  • 低温端:-45℃下电性能稳定,满足户外设备、低温存储设备防护需求;
  • 高温端:+85℃下绝缘电阻与击穿电压无明显衰减,适应设备长时间运行温升环境。

五、品牌与可靠性保障

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:

  • 浪涌循环测试:多次1kA浪涌冲击后性能无明显下降;
  • 温循测试:-45℃~+85℃循环1000次后参数符合规格;
  • 符合IEC 61051-1等国际标准,适合批量生产与长期稳定应用。

六、典型应用场景

  1. 消费电子:手机、平板、智能手表的电源输入端口、充电电路防护;
  2. 工业控制:PLC模块、传感器节点、伺服驱动器的信号/电源接口防护;
  3. 通信设备:路由器、交换机、光纤收发器的RJ45接口、电源模块防护;
  4. 准车载电子:车载充电器、仪表盘辅助电路的过压防护(适配部分非严苛车载场景)。

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。

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
