BSMD1206C-2120T 产品概述

一、产品简介

BSMD1206C-2120T 是佰宏(BHFUSE)推出的一款高可靠性贴片式(SMD)慢断/快断保险丝,属于1206(3.2 × 1.6 mm)封装系列。该产品面向工业、通信、电源和汽车电子等需要过流保护的小型化电路,提供稳定的过流切断能力与宽温度适应性,便于在潮湿、振动和高温环境中长期使用。

二、主要技术参数

  • 型号:BSMD1206C-2120T
  • 品牌:BHFUSE(佰宏)
  • 封装:1206(贴片)
  • 尺寸:长度 3.2 mm,宽度 1.6 mm
  • 额定电流:12 A
  • 额定电压:32 V(DC)
  • 分断能力(Irm):150 A(典型短路分断能力)
  • 熔断 I2t:12.7 A^2s(典型值)
  • 工作温度范围:-55 ℃ ~ +150 ℃
  • 类型:贴片式保险丝(一次性熔断)

三、产品特点

  • 小体积、高密度:1206 封装尺寸,适配常见 SMD PCB 布局,节省板上空间。
  • 高分断能力:150 A 的分断能力可应对大电流短路事件,保证快速切断并保护后级电路。
  • 宽温范围:-55 ℃ 至 +150 ℃ 的工作温度范围,适合严苛环境及工业级应用。
  • 可控熔断性能:熔断 I2t 值控制良好,有助于在过流情况下实现可预测的断开行为,减少对系统的二次影响。
  • 可靠性高:针对贴片回流焊工艺优化,抗振动、耐热循环性能良好。

四、典型应用场景

  • 工业电源模块与配电板过流保护
  • 通信设备及基站电源保护
  • 汽车电子低压配电(需按照汽车级认证匹配使用)
  • 电池保护、充电器与稳压模块
  • 高密度消费电子、嵌入式系统的短路/过载保护

五、安装与使用建议

  • 焊接:推荐采用符合元件制造商回流曲线的回流焊工艺,避免过高峰值温度和过长热曝时间以防内部结构退化。
  • PCB 尺寸与焊盘:按 1206 标准封装布置焊盘,保证良好焊接过渡和散热;焊盘须有适当的丝印和阻焊,防止贴装偏移。
  • 熔断裕量:在选型时留有一定的电流裕量,避免在长期高负载下接近额定电流导致提前熔断。
  • 环境:若用于高湿或化学腐蚀环境,建议进行额外封装或采用防护涂层并参考厂商的环境适应性说明。
  • 验证:在最终系统中进行时间-电流特性验证,以确认熔断时间满足保护要求。

六、可靠性与测试

本型号在出厂前通常经过电气特性测试(额定电流/电压、分断能力、I2t)、温循环测试、振动与机械冲击测试以及焊接热可靠性测试。建议用户在样机阶段进行实际工况下的过载、短路和热老化试验,确保与系统匹配。

七、包装与采购建议

  • 包装:适配 SMD 自动贴装的卷带或盘装形式,便于生产线高速贴片机直接使用。
  • 订购:下单时请核对型号全称(BSMD1206C-2120T)、额定电流与封装,若为汽车级或特殊认证需求,请在采购时注明并索取相应认证文件与可靠性报告。
  • 储存:避免阳光直射、潮湿及极端温度,存放于干燥防静电环境中,长时间存储建议进行烘干处理后再回流焊接。

总结:BSMD1206C-2120T 以其1206小型化封装、12A额定电流及150A高分断能力,适合用于对体积与可靠性有较高要求的电路保护场景。选型与应用时请结合电路的实际时间-电流曲线和工作环境,对熔断裕量与焊接工艺进行校核。若需完整数据手册、时间-电流特性曲线或认证资料,请联系佰宏(BHFUSE)或其授权经销商索取。

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
