BSMD1206-050-30V 产品概述
一、产品简介
BSMD1206-050-30V 为 BHFUSE（佰宏）系列的自恢复型过流保护器件，1206 封装，设计用于在异常过流或短路情况下迅速限流并在故障消除后自动恢复。器件面向电源接口、便携设备与消费电子的电路保护，额定电压 30V，保持电流 500mA，适合对小电流持续工作且要求抗浪涌能力的场景。
二、关键参数
- 尺寸：1206（长度 3.6mm × 宽度 1.9mm × 高度 1.0mm）
- 额定电压 Vmax：30V
- 保持电流 Ihold：500mA
- 跳闸电流 Itrip：1A
- 最大瞬态电流 Imax：40A
- 初始态电阻 Rmin：150mΩ
- 跳断后最大阻值 R1max：850mΩ
- 动作时间：100ms
- 工作温度范围：-40℃ ～ +85℃
- 功率耗散 Pd：800mW
- 品牌：BHFUSE（佰宏）
三、性能特点
- 初始阻值低（≈150mΩ），对正常工作电路压降影响小。
- 快速动作（典型 100ms）能在短时间内限制过流，保护下游器件免受损害。
- 高脉冲承受能力（最高可达 40A），适用于瞬时浪涌或充电器插拔等冲击场景。
- 工作温度范围宽，适应多数工业与消费级应用环境。
- 自恢复特性无需更换，便于维护与长期运行。
四、典型应用
- USB/数据线接口过流保护
- 手机和平板充电保护电路
- 电池管理与电源模块保护
- 家用及办公电子产品输入保护
- 工控与通信设备的小电流保护点
五、选型与使用建议
- 根据电路最大持续工作电流选择 Ihold；若电路常态电流接近 500mA，应选用留有裕度的型号。
- 设计时考虑环境温度对 Ihold/Itrip 的影响，高温会降低保持电流能力，必要时进行温度系数校核。
- 布局上避免将热源靠近器件，保证散热条件以维持稳定特性。
- 推荐按制造商给出的 PCB 焊盘与回流工艺参数处理，避免应力导致可靠性下降。
- 在安全规范和认证方面，请参考佰宏正式数据手册并确认是否满足 IEC/UL 等要求。
六、可靠性与测试
建议在样机阶段进行实际电流-时间特性测试（I-t 曲线）、温度敏感性测试与多次浪涌循环测试，验证在目标应用下的动作一致性与恢复能力。为长期可靠性，还应做焊接热循环和机械振动测试。

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.
