BSMD0603L-150 产品概述
一、产品简介
BSMD0603L-150 是佰宏（BHFUSE）推出的一款表面贴装自恢复保险元件（PTC resettable fuse），封装为0603（长1.9mm、宽1mm、高0.8mm）。该器件针对低压、小空间电路的过流保护需求设计，具有低初始阻值和可重复动作特性，适合便携设备与接口保护。
二、主要参数
- 品牌：BHFUSE（佰宏）
- 封装：0603（尺寸：1.9mm × 1.0mm × 0.8mm）
- 额定电压 Vmax：6V
- 保持电流 Ihold：1.5A（长期不触发）
- 跳闸电流 Itrip：3A（典型动作电流）
- 最大通过电流 Imax：50A（瞬态冲击能力）
- 初始态阻值 Rmin：5mΩ
- 跳断后阻值 R1max：55mΩ
- 动作时间：500ms
- 最大耗散功率 Pd：1W
- 工作温度范围：-40℃ ~ +85℃
三、性能与特性
- 低阻抗：初始仅约5mΩ，减少常态功耗与发热，有利于高效率电源与信号链路。
- 可复位：误触发后冷却恢复，免更换，提升维护便利性。
- 快速响应：典型动作时间约500ms，可在短时过流情况下保护下游负载。
- 抗浪涌：能承受高达数十安培的瞬态冲击（标称50A），适用于有启动电流或短时浪涌的负载。
- 低压应用优化：6V 额定适用于USB、锂电池、便携式模块及小功率电源轨。
四、典型应用
- USB、Type-C 界面过流保护（单口或下游设备）
- 手机、穿戴、蓝牙音箱等便携终端的输出保护
- 摄像头模组、传感器接口和充电电路的短路防护
- 工业低压控制电路和通信设备的局部保护
五、使用建议
- 选型时以最大工作电流不超过 Ihold 为原则；长期工作电流建议保留裕量（≤80% Ihold）。
- 对于频繁高温或高功率损耗场景，注意热量积累与周边器件的热耦合，尽量远离大热源。
- 采用标准回流焊工艺，避免超过推荐温度和时间曲线以保证可靠性。
- 在6V电压限制内使用，超过该电压可能影响动作特性与安全性。
六、封装与可靠性
0603 小型封装适合高密度 PCB 布局，推荐在 PCB 布线处留出散热通道与测试点。器件工作温度范围宽，适应工业级环境；对于关键应用，建议按实际使用环境做热仿真与老化验证。
总结：BSMD0603L-150 以其小体积、低阻抗、可复位与良好瞬态承受力，适合6V以内、空间受限且要求过流保护的各类电子产品。

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.
