BSMD1210-200-6V(BHFUSE 佰宏,封装 1210)是一款表面贴装型自恢复保险丝,适用于 6V 及以下的电路保护。关键参数如下:耐压 Vmax = 6V;最大瞬时电流 Imax = 100A;保持电流 Ihold = 2A;跳闸电流 Itrip = 4A;功耗 Pd = 800mW;初始阻值 Rmin = 15mΩ;跳断后阻值 R1max = 70mΩ;动作时间(至跳闸)约 1s(典型条件);工作温度范围 -40℃ ~ +85℃;外形尺寸 3.5mm × 2.8mm × 1.4mm。
该器件为 PTC 型自恢复保险丝,常态下阻值低(Rmin≈15mΩ),在电路正常工作时仅产生很小的压降和发热。当通过的电流超过跳闸电流 Itrip(典型 4A),在约 1s 的时间内元件阻值迅速上升(跳断后阻值可达 R1max≤70mΩ),从而限制电流并保护下游器件。故障解除后,元件随温度恢复,阻值回落,器件自动复位,无需更换。
型号:BSMD1210-200-6V;品牌:BHFUSE(佰宏);封装规格:1210(SMD)。适用于自动贴片与回流焊工艺,尺寸小巧,便于高密度板级保护设计。
本产品适合需要自动复位、频繁短路保护且对体积有要求的应用场合。在实际选型时,请结合系统最大工作温度、允许压降及瞬态电流特性进行验证测试。若需更详细的热阻、I–t 曲线及回流焊工艺参数,建议向供应商索取完整数据手册。

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.
