BSMD1206-200-6V 产品概述
BSMD1206-200-6V 为佰宏（BHFUSE）推出的 1206 封装可复位聚合物自恢复保险丝（PPTC），专为 6V 级别电源保护和 2A 量级的过流防护设计。器件体积小、响应可靠，适合空间受限且要求重复保护的消费电子、通信和便携设备等场景。
一、主要参数
- 型号：BSMD1206-200-6V（封装：1206）
- 额定电压（Vmax）：6V
- 额定描述：6V 2A
- 保持电流（Ihold）：2A
- 跳闸电流（Itrip）：3.5A
- 最大电流（Imax）：100A（短时冲击能力）
- 初始态阻值（Rmin）：15mΩ
- 跳断后阻值（R1max）：80mΩ
- 功耗（Pd）：1W
- 动作时间：1.5s
- 工作温度：-40℃ ～ +85℃
- 外形尺寸：长度 3.6mm × 宽度 1.9mm × 高度 1.6mm
二、关键特性
- 小尺寸 SMT 1206，便于自动贴片与高密度 PCB 布局；
- 保持电流与描述一致，适合标称 2A 的连续工作场合；
- 在 3.5A 附近迅速跳闸（典型动作时间 1.5s），有效防止过流损伤下游电路；
- 跳断后内部阻值显著上升（≤80mΩ），限制故障电流，且可在故障消除后自动复位；
- 具备较高的短时冲击电流承受能力（Imax 100A），适应启动浪涌或短路瞬态。
三、典型应用
- USB/移动电源及外围保护（5–6V 总线）；
- 智能手机、平板、可穿戴设备的分支电路保护；
- 通信设备、物联网终端、摄像头供电防护；
- 工业低压控制与外设接口保护。
四、设计与使用建议
- 持续工作电流建议不超过 Ihold（2A），为提高可靠性建议设计余量（典型取 80% ≈ 1.6A）；
- 布局时在器件两端预留充分焊盘与散热铜箔，以利热量扩散并稳定动作特性；1206 型建议遵循厂方推荐焊盘尺寸与回流工艺；
- 对于频繁或长期高功率工况，需评估器件热升和 Pd 限制，避免连续近 Pd 工作导致漂移或误动作；
- 在调试阶段应做 Hold/Trip 测试与温度敏感性验证（高低温下的保留与跳闸行为）。
五、可靠性与测试
建议在产品验证阶段执行典型项目：电气参数一致性测试（Rth、Ihold、Itrip）、温度循环、冲击振动和焊接回流耐受性测试。PPTC 的反复复位能力与长期漂移需在目标使用条件下确认。
六、封装与订购提示
1206 表面贴装，兼容 SMT 自动化生产。下单与库存时请注明型号 BSMD1206-200-6V 与品牌 BHFUSE（佰宏），并确认包装形式（卷盘数量）以便生产线对接。
总结：BSMD1206-200-6V 以紧凑的 1206 封装、明确的 2A 等级与可靠的过流动作特性，为 6V 级小电流电路提供经济、可复位的保护方案，适合消费与工业类多种场景应用。若需详尽的 PCB 焊盘建议或作业曲线（I–t、I–R 曲线），可进一步提供测试条件以便输出匹配数据。

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.
