BSMD1812-020-60V 产品概述
一、产品简介
BSMD1812-020-60V 是佰宏（BHFUSE）推出的一款表面贴装型自恢复保险丝（PTC resettable fuse），采用1812封装，专为电路板上的过流及短路保护设计。器件在过流时迅速增阻以限制电流，故障解除后可自动恢复，适合需要重复保护和维护成本低的应用场景。
二、主要参数
- 耐压（Vmax）：60 V
- 最大电流（Imax）：40 A（瞬态或浪涌能力）
- 保持电流（Ihold）：200 mA
- 跳闸电流（Itrip）：400 mA
- 消耗功率（Pd）：800 mW
- 初始态阻值（Rmin）：350 mΩ
- 跳断后阻值（R1max）：5 Ω
- 动作时间：40 ms
- 工作温度：-40 ℃ ~ +85 ℃
- 品牌：BHFUSE（佰宏）
- 封装：1812（SMD）
三、产品特点
- 响应速度快：典型动作时间为40 ms，能在短时间内限制异常电流，保护后端电路。
- 低初始电阻：初始态阻值仅350 mΩ，正常工作时对电路压降与发热影响小。
- 明显的断态阻抗：跳断后阻值最高可达5 Ω，能有效抑制持续故障电流。
- 自恢复能力：故障解除后元件自动恢复导通，避免了手动更换保险丝的麻烦。
- 宽温度范围：-40 ℃ 至 +85 ℃，适应性强，可在多种环境下可靠工作。
四、典型应用
- 板级电源及分配线路过流保护
- 充电器、适配器与电源模块保护
- 通信设备与网络设备的端口保护
- 工业控制与小型自动化设备的短路保护
- 便携设备及消费电子的电源入口保护
五、选型与使用建议
- 选型时应保证器件的保持电流（Ihold）大于电路的最大连续工作电流，以避免误动作。
- 跳闸电流（Itrip）应明显高于正常峰值电流，以防止正常瞬态浪涌导致误断。
- 耐压（60 V）适用于低至中压直流系统，超过该电压时请选用更高耐压产品或并联/串联保护策略。
- 注意最大电流（Imax）通常指瞬时/浪涌能力，长期过载应以Ihold与Pd为参考并留有裕量。
- PCB布线时考虑热散发与周围元件温升，必要时增大铜箔面积或避开高温区。
六、可靠性与注意事项
- 多次跳断与高温环境可能引起特性漂移，实际使用中建议进行寿命与循环测试验证。
- 回流焊工艺兼容性需参考厂商完整资料，避免超过推荐温度/时间造成性能异常。
- 对于安全关键或高可靠性系统，建议与其他保护器件（如快断熔丝、限流电路）配合使用。
七、采购信息
型号：BSMD1812-020-60V；品牌：BHFUSE（佰宏）；封装：1812（SMD）。具体库存、最小订购量与封装带形式请咨询供应商或查看佰宏官方数据手册以获取完整可靠的应用与焊接指导。

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.
