BSMD1206C-1300T 产品概述

一、产品简介

BSMD1206C-1300T 是佰宏(BHFUSE)出品的一款1206尺寸贴片式快速熔断保险丝,专为小型电路的短路与过流保护设计。该产品体积小、响应快、分断能力强,适合在受限空间内为电子模块提供可靠的保护。

二、主要技术参数

  • 型号:BSMD1206C-1300T
  • 品牌:BHFUSE(佰宏)
  • 类型:贴片式保险丝(SMD)
  • 封装:1206(长度 3.2 mm × 宽度 1.6 mm)
  • 额定电流:3 A
  • 额定电压(DC/AC):72 V
  • 分断能力(Breaking Capacity):50 A
  • 熔断 I2t:1.52 A²s(数据用于计算瞬态能量吸收)
  • 工作温度范围:-55 ℃ ~ +150 ℃

三、产品特性与优势

  • 小型化封装:1206 标准封装,适配常见贴片生产工艺,便于自动化贴装与回流焊接。
  • 高分断能力:50 A 的分断能力可应对较大短路电流,减少事故扩展风险。
  • 宽温工作:-55 ℃ 至 +150 ℃ 的温度范围,适合严苛温度环境下的长期工作需求。
  • 快速保护:较低的熔断 I2t(1.52 A²s)意味着对短时大电流脉冲能量敏感,能够在过流发生初期切断电路保护后级元件。
  • 稳定可靠:3 A 额定电流适用于板载电源保护及分路保护,兼顾保护性能与功耗控制。

四、典型应用场景

  • 通信设备与网络设备的电源保护与端口保护;
  • 工业控制模块及自动化设备的分路保护;
  • 消费电子、便携设备以及外设接口的过流保护;
  • 车载电子(在符合具体认证及工况评估前提下)和仪器仪表中的局部保护。

五、封装与安装建议

  • 尺寸:长度 3.2 mm,宽度 1.6 mm(1206),请根据 PCB 布局留出合适焊盘尺寸与过孔布线间距。
  • 焊接:适配回流焊工艺,焊接温度曲线与实际工艺参数应参照厂商推荐的回流曲线以避免过热导致性能变化。
  • 贴装:建议使用自动贴片机及卷盘供料方式,安装时避免机械冲击与弯折应力。

六、选型与使用注意事项

  • 额定电流选择:按正常工作电流留有余量(常见做法为 20%~50% 余量),并综合考虑环境温度与散热条件进行电流降额。
  • 启动电流与浪涌:若电路存在大幅度启动浪涌或重复脉冲,需评估熔断 I2t 与熔断时间曲线,必要时选择具有更高脉冲耐受能力或配合限流元件使用。
  • 环境与可靠性:长时间高温环境会降低保险丝的额定承载能力,建议在高温工况下做温升评估并进行电流降额。
  • 具体参数与认证:如需 UL、AEC-Q 等认证或更详细的机械与电气特性(熔断时间-电流曲线、阻抗、温升等),请以厂商正式 Datasheet 为准并咨询佰宏技术支持。

七、采购与售后

  • 通常以卷带(Tape & Reel)形式供货,满足 SMT 生产需求;具体包装、最小订购量与交期请联系供应商或佰宏代理商确认。
  • 在设计定型前建议样品验证,包括实际板级热特性、浪涌试验与长期老化测试,确保与系统可靠性要求匹配。

如需产品 Datasheet、熔断时间-电流曲线及更详细的应用资料,可提供联系信息以便获取佰宏官方技术文档与样品评估支持。

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
