BSMD1206-030-30V 产品概述
一、产品简介
BSMD1206-030-30V 是佰宏（BHFUSE）出品的一款表面贴装自恢复保险丝（PTC resettable fuse），采用1206封装，专为保护小型电子设备的过流与短路故障而设计。该器件在超过设定电流时自动进入高阻态限流，故障解除后可自动恢复，适合批量化贴片生产和自动化回流焊工艺。
二、主要性能参数
- 耐压（Vmax）：30 V
- 最大电流（Imax）：40 A
- 保持电流（Ihold）：300 mA
- 跳闸电流（Itrip）：650 mA
- 消耗功率（Pd）：600 mW
- 初始态阻值（Rmin）：250 mΩ
- 跳断后阻值（R1max）：1.7 Ω
- 动作时间：100 ms
- 工作温度：-40 ℃ ~ +85 ℃
- 封装尺寸：1206（长 3.6 mm × 宽 1.9 mm × 高 1.0 mm）
三、产品特点
- 响应快速：典型动作时间约 100 ms，可及时保护敏感电路免受瞬态过流损伤。
- 可恢复性：在过流原因消除后自动恢复原低阻状态，减少维护和更换成本。
- 小体积高可靠：1206 小封装适配高密度PCB布局，支持回流焊工艺，便于SMT生产线使用。
- 宽温区适用：工作温度范围广，适用于车载、工业与消费电子等多种环境。
四、典型应用场景
- 手机与便携设备的充电与电源保护模块；
- 工业控制板、传感器接口的过流保护；
- 汽车电子中对低电压总线或外围模块的短路保护（需考虑整车环境及认证要求）；
- USB、电源适配器及电池管理系统的输入输出保护。
五、封装与安装注意
- 标准1206贴片尺寸（3.6 × 1.9 × 1.0 mm），建议按厂家推荐的焊盘设计和回流曲线进行贴装；
- 避免在器件两端施加过大的机械应力，回流焊后建议做外观和电气测试确认；
- 对于高电流路径，请保证周边铜箔及散热设计以控制温升。
六、选型与使用建议
- 根据系统正常工作电流选择保持电流（Ihold）应略高于最大持续工作电流，以避免误动作；
- 对于可能出现的短时冲击电流，比较跳闸电流（Itrip）与系统峰值，确保误触发率低；
- 若系统允许较大的压降或低阻值要求，请留意初始阻值（Rmin 250 mΩ），并在布线中优化阻抗。
七、可靠性与环境适应
- 器件设计用于-40 ℃ 至 +85 ℃工作环境，适合大多数民用与工业应用；
- 出厂通常经过温循环、耐焊接和老化测试，建议在最终应用中做合规性的电气寿命验证。
八、总结
BSMD1206-030-30V 以其小型封装、快速响应与自恢复特性，适合对电流保护有持续运营需求且空间受限的电子产品。选型时重点关注保持电流与跳闸电流匹配、器件热管理和焊接工艺，以确保长期稳定可靠的保护性能。若需样品验证或更详细的电流-温度曲线和封装图纸，可联系佰宏获取完整数据手册。

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.
