SF-1206S050-2 为 BOURNS 出品的贴片慢断(慢熔)保险丝,封装为业界通用的1206(尺寸约 3.2 mm × 1.6 mm)。该器件额定电流 0.5 A、额定电压 63 V,工作温度范围 -20 ℃ 至 +105 ℃,采用陶瓷基体封装,适配卷盘(T/R)自动贴装。设计用于在允许短时浪涌电流的同时,在持续过流或短路情况下可靠断开电路,常用于对启动浪涌敏感的电源与电子系统。
SF-1206S050-2 的陶瓷结构与较高的分断能力使其在发生短路时能可靠切断故障电流并限制能量传递(I²t = 0.03),降低对下游电路的热冲击风险。器件适用于要求可重复装配与自动化生产的工业环境。实际应用中建议根据产品安全规范与系统需求选择合适的保护等级与冗余策略。
型号:SF-1206S050-2,品牌:BOURNS,封装:1206,包装:卷盘(T/R)。在批量采购时请确认生产批次与质量文件(如样品测试报告、可靠性数据)以满足项目验收与供应链一致性要求。

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.
