SMD2920P075TF是RUILON(瑞隆源)推出的贴片式过流保护器件,采用2920封装,专为低压中小电流电路设计,具备自动恢复特性,无需手动更换即可重复使用,是传统一次性保险丝的高效替代方案。
该器件属于聚合物正温度系数(PPTC)自恢复保险丝,核心功能是:电路正常工作时保持低阻,不影响信号传输与功耗;当出现过流(短路、过载)时,快速进入高阻状态限流,保护后端敏感元件;故障排除后自动恢复低阻,无需人工干预。其设计兼顾小型化与高可靠性,适配SMT工艺,可覆盖多领域应用场景。
产品电气参数经严格校验,核心指标及实际意义如下:
采用2920贴片封装(英制尺寸),物理参数及封装优势:
结合参数特性,典型应用包括:
SMD2920P075TF凭借小型化、自动恢复、宽温适配等优势,可有效提升低压中小电流电路的过流防护可靠性,是多领域电路设计的实用选择。

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.
