BSMD1206-075-16V 产品概述

一、产品简介

BSMD1206-075-16V 为 BHFUSE(佰宏)推出的表贴自恢复保险丝(PTC/resettable fuse),采用1206表贴封装(尺寸约3.6mm × 1.9mm × 1.0mm)。器件在过流或短路时能迅速增加阻值限制电流,过热或故障解除后自动恢复初态,适合对板载电源和外设端口的恒温式过流保护。

二、主要参数

  • 耐压(Vmax):16 V(直流额定)
  • 最大允许电流(Imax):100 A(瞬态短路承受能力)
  • 保持电流(Ihold):0.75 A(长期不致跳闸的最大工作电流)
  • 跳闸电流(Itrip):1.5 A(典型触发过流值)
  • 功率耗散(Pd):600 mW(稳态功耗指标)
  • 初始电阻(Rmin):90 mΩ(冷态低阻)
  • 跳断后电阻(R1max):500 mΩ(热态限制电流时的高阻)
  • 动作时间:200 ms(由零到跳闸的参考响应时间)
  • 工作温度范围:-40 ℃ ~ +85 ℃

三、典型应用场景

  • USB、摄像头、蓝牙模块等外设电源保护
  • 电池管理与便携设备的短路/过流保护
  • LED 驱动、小功率电机驱动与电源模块的输入端防护
  • 工业控制板和通信设备的点故障保护

四、选型与使用建议

  • 选型时保持电流 Ihold 应高于正常工作电流并留适当裕量(建议 ≥20%)。
  • 对于有大启动浪涌(inrush)的场合,应以峰值与持续时间评估是否会误跳,必要时并联限流/软启动电路。
  • 注意环境温度对触发特性的影响:高温会降低 Ihold,需考虑热漂移并进行景深测试。
  • 电路板布局建议将 PTC 置于电源入口靠近被保护负载处,减少寄生电阻与热影响。

五、封装与可靠性

1206 表贴封装便于自动贴装与回流焊接,适合集成于高密度 PCB。器件具有良好的循环自恢复能力,但不宜作为长期替代一次性熔断器的高能量开断装置。实际设计中请参考厂商完整数据手册和可靠性评估(如寿命循环、冲击、焊接工艺规范)以保证系统安全性与稳定性。

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
