BSMD1206-300-6V 自恢复保险丝产品概述
一、产品简介
BSMD1206-300-6V 为佰宏（BHFUSE）推出的一款1206 封装表面贴装自恢复聚合物保险丝（PTC），适用于低压电路过流保护。器件尺寸为 3.6mm × 1.9mm × 1.6mm（长×宽×高），设计紧凑，便于自动贴片与波峰/回流焊工艺，适合消费电子、通信与便携设备的小型电源保护需求。
二、关键参数
- 封装：1206（SMD）
- 额定电压（Vmax）：6V
- 保持电流（Ihold）：3A（常态工作时不应超过）
- 跳闸电流（Itrip）：6A（在该电流附近发生显著升阻以限制电流）
- 最大电流（Imax）：100A（短时冲击能力，非连续工作电流）
- 初始态阻值（Rmin）：10mΩ
- 跳断后阻值（R1max）：50mΩ
- 功耗（Pd）：1W（参考热耗散上限）
- 动作时间：4s（达到保护动作所需参考时间）
- 工作温度范围：-40℃～+85℃
三、性能特点
- 小体积、高度集成，方便在有限空间内实现过流保护。
- 自恢复特性：故障消除后能自动恢复导通，无需更换元件，降低维护成本。
- 初始阻值低，导通损耗小，适合对压降敏感的低压应用。
- 可承受短时大电流冲击（标称最大瞬时100A），对启动浪涌或短路冲击具有一定耐受性（建议按实际应用验证）。
四、典型应用场景
- 移动电源、便携式充电器、移动设备电源管理模块；
- USB/Type-C 供电保护、车载低压模块（12V 辅助电路受限于额定电压）；
- LED 灯具驱动电路、显示器电源保护；
- 通信设备、路由器、电源模块的输入/输出保护。
五、选型与使用建议
- 严格按额定电压（≤6V）和保持电流（≤3A）使用；若电路有长期高电流需求，应选择额定更高的型号。
- 动作时间为参考值，实际触发受环境温度、散热条件与电流波形影响，建议在目标应用中做完整热—电仿真与寿命测试。
- 对于频繁过载或持续高温环境，应评估器件老化与恢复能力，必要时采用冗余或更高等级保护。
- 排板与散热：保证焊盘和相邻铜箔有足够散热路径，避免局部过热影响动作特性与寿命。
六、可靠性与包装信息
BHFUSE 品牌制造，适用于常见的工业与消费级工作温度（-40℃～+85℃）。自恢复部件反复动作会逐步改变阻值与触发行程，长期重复触发可能降低保护性能，实际可靠性需依据使用频次与工作环境验证。产品为1206 标准 SMD 包装，支持自动化贴装与回流焊。
如需样品评估、电气热模型或推荐的 PCB 封装尺寸与回流温度曲线，可提供进一步技术支持与数据表以便工程验证。

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.
