RLM102-141N 产品概述

一、产品概述

RLM102-141N 是 RUILON(瑞隆源)推出的一款表面贴装(SMD)浪涌/瞬态抑制元件,型号标识为 RLM102-141N。器件封装为 SMD,基板占位尺寸 5 × 2.8 mm,器件主体直径 φD = 2.7 mm,适合紧凑型电路板的浪涌保护布置。其典型电气特性包括击穿电压 140 V、绝缘电阻 100 MΩ、静态电容约 1 pF,能够承受峰值浪涌电流 1 kA;工作环境温度范围为 -45 ℃ 至 +85 ℃。

二、主要参数

  • 型号:RLM102-141N
  • 品牌:RUILON(瑞隆源)
  • 封装:SMD,外形占位 5 × 2.8 mm,器件直径 φD = 2.7 mm
  • 击穿电压(Vbr):140 V
  • 绝缘电阻:100 MΩ(静态、常温下)
  • 电容:1 pF(典型值,适合高速/高频应用)
  • 浪涌电流能力:1 kA(峰值)
  • 工作温度范围:-45 ℃ ~ +85 ℃

三、性能特点

  • 低电容(约 1 pF):在需要维持信号完整性的高速数据链路或射频线路中影响最小,适合用于对带宽敏感的接口保护。
  • 明确的击穿阈值(140 V):可用于分流或钳位高于正常工作电压的瞬态脉冲,保护后端电路元件免受过压损伤。
  • 较高浪涌能量承受能力(1 kA):适合承受短时高幅值的浪涌冲击,提升系统的抗雷击/浪涌能力。
  • 高绝缘电阻(100 MΩ):在未触发状态下泄漏电流小,对低功耗、低漂移电路影响小。
  • 宽工作温度范围:适合户外或工业级温度场景。

四、典型应用场景

  • 通信接口防护:串行信号线、以太网接口、USB/数据线等需要低电容保护的线路。
  • 电源输入与稳压模块前端的浪涌保护,用于吸收瞬态高压脉冲。
  • 工业控制系统、仪器仪表的输入端防护,适用于存在雷电或切换瞬态干扰的环境。
  • 任何对信号完整性要求高且需要瞬态电压钳位保护的板级电路。

五、封装与安装建议

  • 封装为 SMD,建议按厂方提供的 PCB 封装尺寸和焊盘推荐图进行落位,保证焊点可靠性与热量分布均匀。器件主体直径 φD = 2.7 mm,应预留足够顶层及侧向空间以避免邻近元件干涉。
  • 焊接方式采用与 PCB 工艺匹配的回流焊流程;为保证器件性能与可靠性,建议参照厂方焊接/回流曲线,避免超出器件热应力限制。
  • 布局建议:将器件尽量靠近需保护的输入端或连接器端接地,以缩短高频环路并降低寄生阻抗;若用于对地放电,确保接地平面低阻连接以便快速分流能量。

六、选型与可靠性建议

  • 选型时需考虑系统最大工作电压与器件击穿电压之间的裕量,避免在正常工作条件下频繁接近或触发击穿,从而延长器件寿命。
  • 在高重复浪涌或极端环境下,评估器件在多次冲击后的性能退化,必要时选择更高浪涌能力或并联/级联保护方案。
  • 对于高可靠性项目,建议进行热循环、潮湿负载与浪涌试验验证,并关注长期泄漏电流的漂移情况(与绝缘电阻相关)。

七、注意事项与维护

  • 存储与搬运应防潮、防静电,避免机械冲击造成封装破损。
  • 在设计保护拓扑时,应匹配系统接地并评估能量分流路径,避免将浪涌能量传递到敏感子系统。
  • 详细焊接参数、耐压等级与浪涌脉冲波形的对应关系(例如 8/20 μs、10/1000 μs 等)请参阅厂家详尽数据手册以确保正确使用。

总结:RLM102-141N(RUILON)以其低电容、明确的击穿电压与较高的瞬态承受能力,适合用于需要兼顾信号完整性与浪涌防护的板级应用。选型与布局时请结合具体工作电压、浪涌能量及可靠性要求,并参考厂家完整 datasheet 和焊接指南以获得最佳性能与长期稳定性。

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.
