BSMD1206-050-16V 是佰宏(BHFUSE)推出的一款 1206 封装自恢复过流保护元件(聚合物正温度系数 PTC / 可恢复保险丝),专为表面贴装电路的短路与过流保护设计。该器件体积小、响应迅速、能在过流时快速限流并在故障清除后自动恢复,适用于各类便携式电子、电源管理与工业控制板的过流保护需求。
BSMD1206-050-16V 利用聚合物基体在温度上升时电阻急剧增大的特性:当通过器件的电流超过其保持电流并接近跳闸电流时,器件温度上升导致电阻显著增加,从而限制电流并保护下游电路。故障排除并降温后,聚合物恢复原始低阻态,从而实现自动复位,免去更换保险丝的麻烦。
该产品采用 1206 标准 SMD 封装(3.6 × 1.9 × 1.0 mm),便于高速贴装与回流焊工艺集成。低剖面设计利于在窄小空间中部署。引脚焊盘应按照制造商或行业推荐的 1206 焊盘布局设计,以保证焊接可靠性与热量分布均匀。
结论:BSMD1206-050-16V 适合对体积、自动恢复与快速动作有要求的表面贴装过流保护场景。合理的选型、PCB 布局与热管理能充分发挥其在便携与工业电子设备中的保护作用。如需更详细的电气曲线、回流焊工艺数据或可靠性测试报告,建议联系佰宏(BHFUSE)获取完整数据手册。

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.
