RL302-141N 产品概述
一、产品简介
RL302-141N 是瑞隆源（RUILON）出品的一款玻璃放电管（Spark Gap, SPG），型号标注为 SPG_D3.1X4MM_TM，属于插件（Through‑Hole）封装。该器件采用玻璃封装充入惰性气体，利用气体击穿实现过电压放电保护，适用于通讯、信号及弱电电路的浪涌保护场景，兼顾高浪涌能量承受能力与低电容量对信号完整性的影响。
二、主要技术参数
- 击穿电压（触发电压）：140 V
- 绝缘电阻：≥100 MΩ
- 电容：≈1 pF（典型值，适合高速信号线）
- 浪涌放电电流：3 kA（单次或规定波形下）
- 物理尺寸：直径 φD = 3.1 mm，长度约 4 mm（标称）
- 工作温度范围：-45 ℃ ~ +125 ℃
- 封装形式：插件（通孔焊接）
三、产品特性
- 低电容：约 1 pF，适合用于需要保持信号带宽和低串扰的高速数据/通讯线保护。
- 高浪涌能量承受：可承受高达 3 kA 的短时浪涌电流，适合雷击和开关冲击等瞬态事件防护。
- 稳定触发：标称击穿电压 140 V，在此门槛附近可靠触发，提供有效的过压路径，保护下游设备。
- 宽温度范围：可在 -45 ℃ 至 +125 ℃ 环境下长期工作，适应工业级环境。
- 良好的绝缘性：静态下绝缘电阻≥100 MΩ，保证不致影响电路正常工作。
四、典型应用场景
- 通信基站、交换设备的线路浪涌保护（电话线、以太网线、同轴等）
- 电源输入与配电设备的过电压防护（配合限流元件使用）
- 工业控制、测量与监控设备的防雷/防浪涌设计
- 家电、楼宇对讲、宽带设备等对信号完整性要求高的场合
五、安装与使用注意事项
- 插件焊接时避免长时间高温，推荐温度/时长按照无铅焊接工艺规范执行，以免影响封装气体特性。
- 放电管用于瞬态过电压保护，不应用作持续限压元件；长期承受超过触发电压的直流或大电流会导致损坏。
- 推荐与合适的限流或熔断器、抑制器配合使用，以提高系统可靠性和安全性。
- 放电后若发生明显电性能退化（如触发电压异常、漏电增大），应更换器件。
- 存储与使用环境应避免潮湿、酸碱气体腐蚀及强烈机械振动。
六、采购与技术支持
瑞隆源（RUILON）提供该型号的批量供货与技术资料支持，采购时请确认批次标识与规格一致。若需更详细的浪涌波形测试数据、老化及可靠性报告，建议联系厂家或授权代理获取完整数据手册与测试报告。

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.
