PSMD050 是 KUU 品牌的一款 0805 封装自恢复熔断保护元件,专为低电压直流系统提供过流保护而设计。其额定耐压为 6V,保持电流(Ihold)为 500mA,能在过流时自动断开并在故障解除后恢复导通状态,适用于便携设备、USB 电源、电池管理和其他低压电路的短路/过流防护。
注:Imax 所示为器件可承受的短时脉冲电流,不等同于连续导通电流水平;长时间超过 Ihold 的电流将使器件进入高阻状态以限制电流。
总结:PSMD050 以其小尺寸、自动恢复和适合 5V 级别系统的设计,为低电压、低功耗电路提供了简便可靠的过流保护方案。合理的电流选型与恰当的 PCB 热管理可显著提升其在实际应用中的稳定性与寿命。若有特殊环境或更严格保护需求,建议与供应商沟通以获取更适合的型号或定制方案。

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.
