SF-1206HI600M-2 是 BOURNS 提供的一款 1206 封装板载熔断器(FUSE BOARD MOUNT),额定电流 6A,额定电压 24VDC。该器件面向需要紧凑封装与可靠过流保护的电子设备,工作温度范围宽(-55 ℃ 至 +150 ℃),分断能力可达 80A,适用于多种直流供电系统的短路保护与过流保护设计。
以上参数适合作为器件在电路中选型与可靠性评估的基础,设计时应结合具体的时-电特性(time-current curve)、I^2t 能量和温度系数进一步确认。
SF-1206HI600M-2 采用常见的 1206 表贴封装,便于与标准 SMT 工艺兼容,适合高密度 PCB 布局。封装紧凑,有利于节省板上空间;金属端接设计利于焊接与电气连接稳定性。典型 1206 尺寸便于自动贴装与回流焊处理,生产一致性好。
作为板载熔断器,其基本工作原理是在超过规定限流条件下迅速切断电路,防止更大范围的器件损伤或火灾隐患。80A 的分断能力表明器件能够承受并安全中断较大短路电流,尤其在直流供电(24VDC)环境下具有可靠的开断能力。实际保护性能应基于器件的时间-电流曲线(包括慢熔/快熔特性)和应用场景的短时浪涌特性进行评估。
该器件可在 -55 ℃ 至 +150 ℃ 的宽温度范围内工作,适应工业级甚至严苛环境。高温时的额定电流承载能力与低温差异较大,因此在高温环境中需注意降额设计与热管理。建议在 PCB 布局时考虑良好的散热路径与避免与高热源近距放置,以保证长期稳定运行。
SF-1206HI600M-2 以 1206 紧凑封装实现 6A/24VDC 的板载过流保护,具备高达 80A 的分断能力和宽温范围,适用于工业、通信与各类直流供电系统。合理的电气与热设计、遵循厂商封装与焊接建议以及针对具体故障工况的时-电特性验证,是确保该熔断器在产品中长期稳定可靠工作的关键。欲获得完整技术细节(如时-电曲线、焊接曲线、机械尺寸图等),请参阅 BOURNS 官方数据手册或联系厂商技术支持。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
