BSMD1206-010-60V 自恢复保险丝产品概述

一、产品简介

BSMD1206-010-60V 是佰宏(BHFUSE)出品的一款贴片自恢复保险丝,封装为 1206(长 3.6mm × 宽 1.9mm × 高 1.2mm)。该器件为聚合物正温度系数(PPTC)自恢复保护元件,提供过流自限与故障后自动恢复的保护功能,适用于短路、浪涌及过载保护场合。典型应用包括便携设备电源保护、USB/接口保护、通信与工业电源线保护等。

二、主要性能指标

  • 型号:BSMD1206-010-60V
  • 品牌:BHFUSE(佰宏)
  • 封装:1206(SMD) 长 3.6mm × 宽 1.9mm × 高 1.2mm
  • 额定耐压(Vmax):60 V
  • 初始态阻值(Rmin):1.6 Ω
  • 跳闸后阻值(R1 max):15 Ω
  • 保持电流(Ihold):100 mA(最大连续允许电流)
  • 跳闸电流(Itrip):250 mA(在规定条件下开始明显限流)
  • 最大冲击电流(Imax):40 A(短时浪涌承受能力)
  • 功耗(Pd):600 mW(额定功耗)
  • 工作温度范围:-40 ℃ ~ +85 ℃
  • 动作时间:1 s(典型或指定测试条件下动作响应时间)

三、工作原理与典型特性

PPTC 自恢复保险丝在正常工作时处于低阻态(本型号初始态约 1.6 Ω),当电路电流超过设定的跳闸电流时,元件内部温度上升使得阻值陡增(跳闸后阻值可达典型的 15 Ω 级),从而限制通过电流,保护下游电路免受损害。故障清除并冷却后,阻值恢复到初始低值,实现自动复位。Imax 表示器件能承受的短时浪涌峰值,适用于瞬时短路或启动浪涌。

四、典型应用场景

  • USB、串口、接口与外设供电保护(5 V、12 V 环境,可用于更高电压至 60 V)
  • 消费类与便携式设备的电源输入保护
  • 工业与通信设备的线路保护(48 V 系统可用)
  • 模块化电源、适配器和电池管理的过流防护

五、选型建议与使用注意

  • 选型原则:保持电流 Ihold 应高于电路最大持续工作电流,跳闸电流 Itrip 应接近或略高于故障开始的电流。通常将器件 Ihold 设为正常工作电流的 1.1–1.3 倍,Itrip 在短时过载情形下能及时动作。
  • 电压要求:确保器件耐压 Vmax ≥ 系统最大工作电压(本型号为 60 V)。
  • 热环境影响:周围温度升高会降低 Ihold 与 Itrip,请按工作温度范围评估实际电流容许值并做必要的降额。
  • 布局建议:靠近被保护源端布置,减少跳闸时的能量传递;保证良好散热路径以利复位。
  • 焊接与工艺:按厂家推荐的回流温度曲线进行焊接,避免超温或长时间高温烘烤导致性能退化。避免机械应力与弯折。

六、包装与可靠性

该产品为标准 SMD 封装,适用于自动贴装与回流焊流程。存储时应防潮并避免长时间暴露在高温高湿环境中,建议按照行业常规保质期与防潮包装管理。对于关键应用,建议进行环境应力筛选与长寿命测试验证。

总结:BSMD1206-010-60V 提供便捷的自恢复过流保护,适合 60 V 以下多种应用场景。选型时需综合考虑工作电流、环境温度与浪涌特性,以保证保护效果与系统可靠性。若需更详细的 IV 特性曲线、回流焊曲线或可靠性数据,建议联系供应商获取完整数据手册。

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
