SMD2920B185TF 为 Brightking(台湾君耀)出品的贴片式自恢复保险丝(PPTC),适用于电路中过流保护与短路防护。该器件在正常工作时阻值较低,发生过流并跳闸后恢复高阻态以限制电流,故在需要重复保护且不易更换熔断器的场景中具有明显优势。
主要参数一览(典型/最大值)
总结:SMD2920B185TF 以其自恢复特性、低初始阻值及适配 SMT 的封装,适合各类需要重复过流保护的电源输入及局部电路保护需求。设计时应根据 Ihold/Itrip 规格进行电流裕度评估,并在目标温度与冲击条件下完成验证测试,确保长期可靠运行。

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.
