AVR-M1005C080MTABB 产品概述

一、主要参数与型号说明

AVR-M1005C080MTABB 为 TDK 出品的微型压敏电阻(Varistor),封装 0402(公制 1005),适用于微型化电子设备的瞬态过压保护。主要电气参数:压敏电压(Vr)= 8V,钳位电压(Vc)≈ 15V,工作电压(DC)= 5.5V,峰值浪涌电流(Ipk)= 3A,吸收能量 ≈ 20 mJ,静态电容 = 100 pF @1 kHz。

二、性能与特点

  • 小体积:0402 超小封装,便于高密度 PCB 布局与空间受限的便携设备。
  • 钳位能力:在短时脉冲下可将电压钳位至约 15V,保护下游器件免受高电压冲击。
  • 快速响应:压敏材料对瞬态电压有集中过渡性导通,适合抑制瞬态浪涌与静电放电引起的短脉冲。
  • 电容特性:约 100 pF 的静态电容在高频信号线上会产生影响,需在高速差分或射频路径中谨慎使用。

三、典型应用场景

  • 5V 电源 rails(单板、模块供电)上的浪涌保护(工作电压 5.5V,适配 5V 系统)。
  • 连接器输入(USB、电源插孔)附近作为第一道防护,吸收外部短时脉冲。
  • 低功耗 IoT、传感器前端及便携式终端的局部防护组件(非主防护用于高能冲击)。

四、设计与使用要点

  • 布局:靠近被保护端口或元件放置,走短回流路径并直接连接到地或电源线两端。睡面焊盘宜最短引线以降低感抗。
  • 与信号完整性:100 pF 容量可能对高速数据线(USB2.0/高速 SPI 等)造成阻抗偏移与带宽下降,若保护数据线需验证时序与误码率。
  • 功率与耐受:能量吸收仅 20 mJ、峰值 3A,适合静电和短脉冲防护,不可用于持续或大能量浪涌场合(如直击雷或长期过压)。
  • 焊接与可靠性:兼容常规回流焊工艺;使用时考虑热循环及机械应力对 0402 小封装的影响,建议按厂商推荐的 PCB 焊盘及焊接参数。

五、选型建议与注意事项

  • 若工作电压长期接近 5.5V,应留有裕量或选用更高工作电压型号以确保可靠性。
  • 对于需要更高浪涌能量吸收的场合,考虑体积更大或并联/级联解决方案。
  • 在高速接口上优先评估电容影响,必要时选用专用低容抗静电二极管(ESD 二极管)或在 varistor 与信号线间增加串联阻抗配合使用。

总结:AVR-M1005C080MTABB 适合用于 5V 体系中对瞬态过压与静电的局部保护需求,体积小、响应快,但能量吸收与电容特性需在设计阶段综合评估,确保满足可靠性与信号完整性要求。

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
