BSMD0603-075-8V 产品概述

一、产品简介

BSMD0603-075-8V 为佰宏(BHFUSE)生产的一款0603封装自恢复保险元件(SMD自恢复熔断器),尺寸为0.06×0.03英寸(1.5×0.8 mm),适用于空间受限的便携式和板级保护应用。该器件符合RoHS,无铅且无卤,具有低剖面与低电阻的特点,并可兼容高温回流焊工艺。

二、主要电气参数

  • 额定耐压(Vmax):8 V
  • 最大持续电流(Imax):40 A(短时或浪涌能力)
  • 保持电流(Ihold):0.75 A(750 mA)
  • 跳闸电流(Itrip):1.5 A
  • 动作时间:约 8 s(在指定过流条件下,实际时间随过流倍率及环境温度变化)
  • 功耗(Pd):500 mW(额定功耗/热容限)
  • 初始态电阻(Rmin):60 mΩ
  • 跳断后最大电阻(R1max):450 mΩ
  • 工作温度范围:-40 ℃ 至 +85 ℃

三、结构与特性

  • 尺寸小、低剖面,适合高密度贴片设计。
  • 响应迅速,对异常或故障电流能快速限制电流,保护下游元件。
  • 低闭合电阻有助于降低功耗和发热,改善电源效率。
  • 与高温焊料兼容,适合无铅回流焊工艺,便于标准SMT生产流程。
  • RoHS 合规、无卤、环保。

四、典型应用场景

  • 笔记本、台式机主板与外设电源保护。
  • 手机及平板的充电口、USB 接口、摄像头模组或电源管理子系统保护。
  • 便携式设备的电源总线、数据接口、模块供电保护。
  • 任何需要在有限空间内实现过流保护的板级应用。

五、设计与使用建议

  • 建议将器件放置于电源入口或敏感模块的近端,优先保护下游电路。
  • 在接近 Ihold 工作电流时应考虑降额留有余量,避免长期接近保持电流导致热累积与误动作。
  • 动作时间随过流倍数与环境温度变化,若需要更快保护应选择Itrip更低或响应更快的型号。
  • 多次触发后器件闭合阻值可能上升(R1max 指定),如需长期可靠性,评估实际使用中重复触发次数对系统影响。
  • 与PCB焊盘设计配合,按0603贴片工艺推荐的焊盘尺寸和锡膏量,保证可靠焊接与热性能。

六、可靠性与注意事项

  • 工作环境温度、周围器件散热条件会影响器件的热稳定性与动作特性,应在目标工况下作热验证。
  • 虽有短时高浪涌承受能力(Imax),但不宜将其作为替代传统熔断器或限流器的长期解决方案。
  • 存储与运输避免机械压迫和强烈振动,标准SMT防潮措施建议符合一般无源器件规范。

七、订购信息与封装

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
