BSMD1206-110-6V 自恢复保险丝（BHFUSE 佰宏）
一、产品简介
BSMD1206-110-6V 是佰宏（BHFUSE）推出的一款 1206 封装自恢复保险丝（PTC/自恢复熔断器），用于对过流、短路等异常情况提供自动保护。器件在异常电流解除后可自动恢复导通，适合对重复性短路或暂态过流有保护需求的电子产品。
二、主要参数
- 跳断后阻值 (R1max)：250 mΩ
- 初始态阻值 (Rmin)：40 mΩ
- 耐压 (Vmax)：6 V
- 跳闸电流 (Itrip)：2.2 A
- 最大电流 (Imax)：100 A（瞬时承受能力）
- 保持电流 (Ihold)：1.1 A
- 动作时间：300 ms
- 最大消耗功率 (Pd)：800 mW
- 工作温度：-40 ℃ ~ +85 ℃
- 封装：1206
三、产品特性
- 低初始电阻（约 40 mΩ），对正常工作时的压降和发热影响较小。
- 明确的保持电流与跳闸电流区分，便于电路保护门槛设计。
- 跳闸后阻值显著上升（≤250 mΩ），可有效限制故障电流。
- 能承受高达百安级的瞬态冲击，适合瞬态短路保护场景。
- 宽工作温度范围，适用于多种环境条件下的可靠保护。
四、典型应用场景
- 手机、平板等便携设备的充电与数据口过流保护。
- USB、Type-C、AUX 等接口电源保护。
- 电源模块、充电器、电源管理板的输入保护。
- 家用电子、工业控制等对重复性短路有自恢复需求的场合。
五、使用建议
- 选型时应保证正常工作电流远低于 Ihold（1.1 A），以避免持续发热或误动作；在有短时浪涌的场合，注意与 Imax 的瞬态承受能力匹配。
- Pd（800 mW）表示器件在环境条件下的热容限，长时间接近该功率会引起温升，建议在PCB布局和散热设计中留有裕量。
- 1206 封装需按厂家推荐的贴片焊接工艺进行回流焊，避免过高温度或长时间焊接导致性能劣化。
- PCB 布局建议：器件两端焊盘对称，走线短而宽，尽可能靠近保护目标端口放置以缩短故障回路长度。
六、可靠性与采购注意
- 工作温度范围 -40 ~ +85 ℃，在极端环境下使用请进行实际温升评估与老化测试。
- 常见包装方式为盘带（Tape & Reel），量产时建议向供应商确认包装与批次信息。
- 选购时注意与系统最大工作电压、持续电流以及可能的浪涌电流一并校核，必要时采用更高等级或并联/串联的保护方案。
BSMD1206-110-6V 提供了在有限空间内可靠且可自动恢复的过流保护选项，适合多数消费与工业电子设备的接口与电源保护需求。需要更详细的热特性曲线、回流焊工艺或样片测试数据，请联系佰宏或授权分销商获取器件数据手册与试样。

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.
