2R090TB-8 — RUILON(瑞隆源)90V 10kA 双端气体放电管产品概述

一、产品概述

2R090TB-8 是 RUILON(瑞隆源)推出的一款轴向引线封装的双端气体放电管(GDT),用于对瞬态过电压和雷击、开关冲击引起的大电流脉冲提供快速放电保护。器件设计紧凑,外形直径φ8mm、总高度6mm,适合安装在线路板或直插式保护模块中。工作温度范围宽(-40℃ ~ +90℃),可在苛刻环境下长期稳定工作。

二、主要参数

  • 极数:2(双电极)
  • 直流击穿电压(Vdc):90V( ±20%)
  • 冲击击穿电压(Vimp):600V
  • 脉冲放电电流:10kA(峰值)
  • 极间电容:1.5pF(典型)
  • 工作温度:-40℃ ~ +90℃
  • 封装:轴向引线,便于插装和焊接
  • 外形尺寸:直径φ8mm,高度6mm

三、产品特点

  • 高浪涌耐受能力:单次脉冲放电电流高达10kA,可有效吸收雷电和开关冲击能量。
  • 低触发电容:1.5pF 的极间电容使其适用于对信号完整性要求高的通信线路和数据接口,不会显著增加线路串扰或衰减。
  • 明确的触发与保持特性:90V 直流击穿电压(±20%)配合600V 冲击击穿电压,能在高压瞬变时迅速导通、在正常工作电压下保持绝缘。
  • 宽温度适用:适合工业级工作环境,可靠性高。
  • 轴向引线结构:便于通过波峰/手工焊接安装与更换,适合模块化设计。

四、典型应用场景

  • 电信与数据线路防护:受益于低电容特性,适用于电话线、DSL、以太网等接口的第一级浪涌保护。
  • 电源与信号端口保护:用于工控电源输入、门控信号线及监控系统的过压防护。
  • 配合其他防护元件:可作为浪涌保护装置(SPD)中的主放电元件,与气体放电器、压敏电阻(MOV)或TVS二极管协同工作,实现更宽频谱的过电压防护。
  • 通信基站、配电箱、安防设备等需抗雷击和冲击的场合。

五、安装与使用注意

  • 在布置保护网络时建议将 GDT 放置在线路的第一防线,尽量靠近外来入线端,减小引线电感以提升放电效率。
  • 轴向引线型应避免在焊接时的高温持续过长,遵循厂商推荐的回流/手工焊接温度曲线以保证密封与性能。
  • 触发电压有±20%公差,设计时需考虑最小与最大值对系统保护等级的影响。
  • 气体放电管属于一次性承受极大能量的器件,遭遇多次高能冲击后其放电特性可能变化,应在维护策略中预留检测和更换周期。
  • 避免在高湿或强腐蚀性气体环境中长期裸露,应结合封装或外壳防护措施。

六、可靠性与包装

产品符合一般工业级可靠性要求,适配宽温工况与高浪涌测试。轴向引线封装便于批量加工与检测。为确保长期稳定性,建议按厂方提供的存储条件保存,避免潮湿与剧烈振动影响器件密封结构。

总结:2R090TB-8 以其高冲击耐受能力、低极间电容和紧凑轴向封装,适合用于对信号完整性与抗雷击能力有双重需求的线缆与接口保护场合,是工业与通信类防护设计中的可靠选择。若需更详细的电气特性曲线、冲击波形耐受能力数据或封装图纸,可联系 RUILON 厂家技术支持获取完整数据手册。

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
