BSMD2920-075-60V自恢复保险丝产品概述

一、产品基本定位与品牌背景

BSMD2920-075-60V是佰宏(BHFUSE) 推出的一款贴片式自恢复过流保护器件。自恢复保险丝的核心优势是故障排除后自动恢复导通,无需手动更换,能有效降低设备维护成本与故障停机时间。佰宏作为专注保险丝研发生产的厂商,该产品延续了品牌在低压过流防护领域的可靠性设计,适配多类电子设备的防护需求。

二、核心电气参数深度解析

该产品参数经过精准设计,关键指标明确,便于电路匹配:

  1. 耐压与电流阈值:最大耐压Vmax=60V,覆盖12V/24V/48V等常规低压系统;最大耐受电流Imax=40A(峰值),可应对瞬间浪涌;保持电流Ihold=750mA(正常工作电流需低于此值,避免误动作);跳闸电流Itrip=1.5A(过流触发阈值,为Ihold的2倍,符合自恢复保险丝典型设计逻辑)。
  2. 阻值特性:初始态最小阻值Rmin=100mΩ,低阻值设计减少正常工作时的电压降与功率损耗,不影响电路性能;跳断后最大阻值R1max=1Ω,高阻态可有效限制故障电流,保护后级电路。
  3. 动作与功耗:动作时间300ms(过流到跳断的响应时间),既避免瞬间浪涌误触发,又能快速切断故障电流;最大耗散功率Pd=1.5W,确保设备正常工作时的热稳定性。
  4. 温度范围:工作温度覆盖-40℃~+85℃,宽温设计适应工业、车载等恶劣环境。

三、机械封装与尺寸规格

该产品采用2920贴片封装,尺寸紧凑:长度7.98mm、宽度5.44mm、高度1.3mm。贴片封装适配SMT自动化生产,贴装效率高;小尺寸设计适合手机、便携设备等小型化电子设备的空间布局,不占用额外安装空间。

四、典型应用场景

结合参数特性,BSMD2920-075-60V适用于以下场景:

  1. 消费电子:手机、笔记本电脑的电池保护电路、USB接口过流防护(适配USB2.0/3.0的电流范围);
  2. 工业控制:PLC模块、传感器节点、小型电机驱动的过流保护(宽温特性满足工业环境需求);
  3. 汽车电子:车载仪表盘、USB充电器、小功率辅助设备的过流防护(12V/24V系统耐压足够,宽温适配车载环境);
  4. 通信设备:路由器、交换机的端口保护(低阻值不影响信号传输质量)。

五、关键性能优势

  1. 自恢复特性:故障排除后(如短路解除)自动恢复导通,无需更换器件,降低维护成本;
  2. 低损耗设计:初始态100mΩ低阻值,正常工作时功率损耗小,不影响电路效率;
  3. 宽温可靠性:-40℃~+85℃温度范围,覆盖多类应用场景的环境需求;
  4. 紧凑适配性:2920贴片封装,适配小型化设备与自动化生产;
  5. 明确动作阈值:Ihold与Itrip的比例设计合理,便于电路设计时精准匹配负载电流,避免误触发或动作延迟。

六、选型与使用注意事项

  1. 电流匹配:正常工作电流需≤750mA,过流电流需≥1.5A,确保动作可靠性;
  2. 电压匹配:电路工作电压需≤60V,避免耐压不足导致器件损坏;
  3. 热管理:安装位置需保证散热,避免局部过热(如远离大功率器件);
  4. 环境温度:工作环境需在-40℃~+85℃范围内,超出可能影响动作特性;
  5. 焊接规范:贴片焊接需遵循回流焊工艺(如峰值温度≤260℃,时间≤10秒),避免损伤器件内部结构。

该产品凭借稳定的过流保护性能、紧凑的封装设计与宽温适应性,成为多类电子设备过流防护的可靠选择。

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
