BSMD1812-075-33V(BHFUSE 佰宏)是一款面向中低电压电源保护的自恢复过流保护元件(聚合物PTC/PTC型自恢复保险),采用1812贴片封装(尺寸约4.73mm × 3.41mm × 1.1mm)。器件在正常工作时具有低阻抗并允许持续通过一定电流;当电流超过设定跳闸电流时,器件迅速升温、阻值显著上升以限制电流,从而保护电路并在故障消失后自动恢复。
总结:BSMD1812-075-33V 是一款体积小、响应快、自恢复的过流保护元件,适合33V及以下电源线的保护应用。合理的选型与良好的热设计能最大化其保护效果并延长使用寿命。若需更详细的电气/热曲线或推荐电路,请联系供应商获取完整数据手册与应用笔记。

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.
