SMD2920B260TF/24 是台湾 Brightking(君耀)出品的一款表面贴装型自恢复保险丝(PPTC)。该器件以小尺寸封装和可靠的过流保护能力为特点,适合对短路或过载条件下要求自动限流并在故障清除后自动恢复的电子系统。其工作电压上限为 24V,面对消费类和工业低压电源保护具有良好适配性。
2920 封装尺寸紧凑(约 7.98 × 5.44 × 1.6 mm),适合双面贴装和自动化 SMT 生产。封装提供良好的焊接可靠性与热稳定性,器件表面标识便于生产追溯。作为聚合物正温度系数(PPTC)元件,其阻值随温升迅速上升以限制电流,且在故障解除后会冷却恢复至初始低阻状态。
在需要更高保持电流或更低初始阻值的场合,可参考同类封装或更大尺寸的 PPTC;若需更快动作或精确熔断特性,应考虑传统一次性熔断器或电子限流方案。采购时建议比对 Ihold/Itrip、阻值、尺寸与环境规格,确保与系统兼容。
如需进一步的数据(如详细 I–t 曲线、阻值随温度曲线或推荐焊盘尺寸),建议向 Brightking 官方或授权代理索取完整数据手册以便做最终设计确认。

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.
