BF091M气体放电管(GDT)产品概述

BF091M是槟城(Bencent)品牌推出的一款小型化表面贴装(SMD)气体放电管,属于过电压保护核心器件,主要用于电子设备的浪涌防护,可有效抑制雷击、电源瞬态过压、静电放电等干扰,保障电路稳定运行。

一、产品基本属性与品牌背景

BF091M由国内专业防护器件厂商槟城(Bencent)研发生产,定位于中低电压、高浪涌耐受的通用型气体放电管,适用于通信、消费电子、工业控制等多领域的接口与电源防护场景。作为气体放电管(GDT)的典型代表,其通过内部气体电离实现过压导通,快速泄放浪涌能量后恢复高阻态,不影响电路正常工作。

二、核心电气性能参数

BF091M的电气参数针对防护需求做了精准设计,关键指标如下:

  • 直流击穿电压(Vdc):90V±20%,实际击穿电压范围为72V~108V,满足低电压电路的过压触发需求;
  • 脉冲放电电流:5kA(8/20μs波形),可承受强浪涌冲击(如近距离雷击、电源尖峰),保护后端敏感器件;
  • 极间电容:0.8pF(典型值),低电容特性确保不干扰高频信号传输(如射频、高速USB接口);
  • 冲击击穿电压(Vimp):600V,指器件在1.2/50μs冲击电压下的击穿阈值,进一步提升过压防护可靠性;
  • 极数:2极(双端)设计,可直接并联于被保护电路两端,安装简单。

三、封装与物理尺寸

BF091M采用小型化SMD封装,物理尺寸为4.2mm(长)×5mm(宽)×5mm(高),体积紧凑,适配高密度PCB布局(如智能手机、小型路由器等便携设备)。表面贴装工艺兼容自动化生产,可通过回流焊实现高效组装,降低人工成本。

四、典型应用场景

结合参数特性,BF091M适用于以下场景:

  1. 通信设备:基站射频接口、光纤收发器、路由器LAN/WAN口的浪涌防护;
  2. 消费电子:智能手机/平板的充电接口、耳机孔、USB Type-C接口的静电与浪涌防护;
  3. 工业控制:PLC输入输出模块、传感器接口、工业以太网的过压保护;
  4. 汽车电子:车载通信总线(CAN/LIN)、车载充电器接口的浪涌防护(适配宽温环境)。

五、产品优势特点

BF091M的核心优势体现在以下几点:

  • 高浪涌耐受:5kA脉冲电流覆盖多数实际浪涌场景,无需额外并联多个器件;
  • 低电容干扰:0.8pF极间电容不影响高频信号完整性,适合射频、高速数字电路;
  • 小型化设计:紧凑尺寸适配轻薄化设备,满足当代电子设备的 miniaturization 需求;
  • 宽温适应性:工作温度范围为-40℃~+90℃,可在低温(如北方户外)、高温(如车载环境)下稳定工作;
  • 高可靠性:冲击击穿电压与直流击穿电压的配合,确保过压触发精准,无漏保风险。

六、使用注意事项

  1. 安装时需确保器件与PCB焊盘接触良好,避免虚焊影响浪涌泄放;
  2. 若应用场景浪涌能量超出5kA,可并联多个BF091M提升防护能力;
  3. 存储时需避免高温、高湿环境,防止器件性能老化。

BF091M凭借平衡的防护性能与小型化设计,成为多领域电子设备过压保护的高性价比选择,可有效降低浪涌干扰导致的设备故障风险。

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
