BSMD1206-110-16V 产品概述
一、概述
BSMD1206-110-16V 是佰宏（BHFUSE）出品的一款 1206 封装自恢复保险丝（PTC），适用于对过流保护、小型化和自动恢复有要求的电子设备。器件在过载或短路时迅速增阻限流，故障消除后自动恢复低阻状态，免去更换熔断器的麻烦，提升维护便捷性。
二、主要参数
- 封装：1206（SMD）
- 尺寸：长 3.6 mm × 宽 1.9 mm × 高 1.4 mm
- 初始阻值 Rmin：40 mΩ
- 跳断后阻值 R1max：250 mΩ
- 额定耐压 Vmax：16 V
- 跳闸电流 Itrip：2.2 A（典型动作）
- 保持电流 Ihold：1.1 A
- 最大浪涌电流 Imax：100 A（短时冲击）
- 动作时间：约 300 ms（在规定过流条件下）
- 功耗 Pd：800 mW
- 工作温度：-40 ℃ 至 +85 ℃
- 品牌：BHFUSE（佰宏）
三、产品特性
该型号特点为体积小、响应快、恢复可靠。初始阻值低，能够在正常工作下将压降与发热降到最低；在过流时阻值上升显著以限流保护电路。支持较高的瞬态冲击电流（Imax），适合有开机浪涌或短时冲击的场景。
四、典型应用
- 手机配件、便携式设备的电源保护
- USB、电池管理与充电器线路保护（16 V 以内）
- 工业控制、智能家居的局部过流保护
- 需要自动恢复功能的消费电子产品
五、选型建议
- 常态工作电流应低于 Ihold，推荐选择实际工作电流 ≤ 80% Ihold 以避免误动作。
- 若电路存在长时微过流或温升敏感场景，应考虑余量或更高规格型号。
- 注意 Vmax 为最大适用电压，系统工作电压应低于该值。
六、PCB封装与焊接建议
采用标准 1206 焊盘设计，保证焊盘尺寸与焊膏覆盖均匀以利热传导。遵循元件制造商或 IPC/JEDEC 的回流焊温度曲线，避免超过器件允许的峰值温度。贴装时注意不要对元件施加过大机械应力。
七、使用注意事项与可靠性
- 长期靠近热源或在高温环境下，Ihold / Itrip 特性会有变化，应在设计时考虑温漂与老化裕度。
- 若需通过认证或在严苛环境（如高湿、腐蚀）中应用，建议参照厂方可靠性测试报告并做系统级验证。
- 对于关键保护场合，可与其他保护元件（熔断器、限流电路）配合使用，形成多重保护策略。
该器件以体积优势与自动恢复特性为主要卖点，适用于对板级过流保护有自动恢复需求且工作电压 ≤16V 的各类电子产品。

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.
