2R400TB-8 轴向引线压敏电阻产品概述
一、产品定位与核心功能
2R400TB-8是瑞隆源（RUILON）推出的一款双向轴向引线压敏电阻，核心作用是针对电子电路中的过电压浪涌（如雷击、开关瞬态、电网波动）进行快速防护，避免敏感元器件因过压击穿、烧毁。该产品以「高浪涌容量+低极间电容」为核心特点，适配多场景的过压保护需求，平衡了防护性能与应用灵活性。
二、关键性能参数深度解析
1. 电压与击穿特性
- 直流击穿电压（Vdc）：标称400V，精度±20%，实际击穿范围为320V~480V，满足多数电子电路的过压阈值需求（如交流电源端的浪涌防护）；
- 冲击击穿电压（Vimp）：850V（对应8/20μs标准浪涌波形），反映产品在突发浪涌下的实际响应能力，确保瞬态过压快速导通泄放；
- 极间电容：仅1.5pF，远低于普通压敏电阻（通常5pF以上），在高频电路（如通信接口、射频模块）中使用时，不会对信号传输造成明显衰减或干扰，实现「信号+电源」复合防护。
2. 浪涌防护能力
- 脉冲放电电流：10kA（8/20μs波形），属于中高容量压敏电阻，可有效应对：
- 户外设备的感应雷/直击雷浪涌；
- 大功率开关（如电机、继电器）切换产生的瞬态浪涌；
- 电网电压突变（如市电波动、浪涌冲击）。
3. 环境与安装适应性
- 工作温度：-40℃~+90℃，覆盖工业级、户外设备的高低温环境（如北方冬季、南方夏季的户外终端）；
- 封装与脚距：轴向引线封装，引脚间距4.4mm，符合常规PCB插件布局规范，焊接便捷，抗氧化性强。
三、封装与可靠性设计
2R400TB-8采用陶瓷基压敏材料，具备稳定的压敏特性，多次浪涌冲击后性能衰减小（符合IEC 61643标准）；轴向引线为镀锡铜线，焊接可靠性高，长期使用不易氧化。瑞隆源出厂前对产品进行「浪涌循环测试、高低温循环测试、引脚拉力测试」等可靠性验证，确保批量一致性与长期稳定性。
四、典型应用场景
- 电源系统防护：开关电源、UPS电源、充电桩的交流输入端，应对电网浪涌与雷击；
- 通信设备防护：路由器、交换机、光纤收发器的信号/电源接口，低电容不影响高频信号传输；
- 工业控制设备：PLC、传感器、变频器的电源端防护，适应-40℃~+90℃的工业环境；
- 家电与消费电子：空调、洗衣机、智能电视的防雷与开关浪涌防护，提升产品耐用性。
五、产品核心优势
- 防护性能均衡：10kA浪涌容量覆盖多数场景，低电容适配高频电路；
- 环境适应性强：宽温范围满足户外/工业复杂环境；
- 安装便捷：轴向引线+标准脚距，兼容常规PCB设计；
- 成本可控：性能稳定，适合中低端防护场景的批量应用。
2R400TB-8凭借高性价比与均衡性能，成为电子设备过压防护的常用选型之一，可有效降低浪涌对电路的损坏风险。

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.
