BSMD3425-260-60V 自恢复保险丝 产品概述
一、产品简介
BSMD3425-260-60V 是 BHFUSE（佰宏）推出的一款表面贴装自恢复保险丝（PPTC），用于电路过流保护。该器件在正常工作时阻值低、功耗小；遇到过流或短路时快速增温升阻限制电流，故障消除后可自动冷却恢复导通，适合反复保护应用。
二、主要技术参数
- 耐压（Vmax）：60 V
- 最大电流（Imax）：20 A
- 保持电流（Ihold）：2.6 A（常温条件下，器件在此电流下不会发生动作）
- 跳闸电流（Itrip）：5.2 A（典型动作电流）
- 消耗功率（Pd）：2.5 W
- 初始态阻值（Rmin）：20 mΩ
- 跳断后阻值（R1max）：120 mΩ
- 动作时间：8 s（从过流到明显限流的典型时间）
- 工作温度范围：-40 ℃ ~ +85 ℃
- 外形尺寸：长 9 mm × 宽 6.7 mm × 高 2 mm
- 封装：3425（BSMD3425 系列外形）
三、产品特点
- 可复位：过流后无需更换，故障解除自动恢复，维护成本低；
- 低初始电阻：Rmin 仅 20 mΩ，适合对压降敏感的供电线保护；
- 快速限流：Itrip 5.2 A 且动作时间短，能有效保护下游元件与电缆；
- 宽温区稳定性：-40 ℃ 至 +85 ℃ 的工作范围，适合多种工业与消费环境；
- 体积小巧：3425 封装便于 SMD 贴装与自动化生产。
四、典型应用
- 手机、平板及便携式设备 USB、充电口过流保护；
- 电源适配器、DC-DC 模块输入/输出保护；
- 汽车电子非关键回路保护（需注意车规环境验证）；
- 工业控制、家电及通信设备的短路/过载防护。
五、PCB 与选型建议
- 布局时保证器件周围散热空间，避免紧邻大功率发热元件；
- 对于高电流路径建议使用宽铜箔并加厚，尽量减小走线电阻；
- 若工作电流接近 Ihold，应选用留有裕量的型号以避免误动作；
- 在高温环境或长时间大电流工况下，应验证热耦合与动作时间是否满足要求。
六、可靠性与注意事项
- 遵循推荐的回流焊工艺温度曲线，避免超过元件最大温度；
- 长期在高温或频繁过流循环下，器件特性（Ihold/Itrip）可能随时间漂移，应做寿命验证；
- 不建议用作短时间保险丝替代高断电能力的场合，关键安全回路请配合冗余保护方案。
七、包装与订购
型号：BSMD3425-260-60V；品牌：BHFUSE（佰宏）；封装：3425 SMD。订购时请注明工作温度与批次，以便获取完整的出厂测试数据与曲线图。若需样品或技术支持，可联系供应商获取详细 I-T、I-V 和热特性曲线。

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.
