07D471K 是 RUILON(瑞隆源)推出的一款插件式金属氧化物压敏电阻(MOV),专为工业级浪涌保护设计。该器件在典型的工业供电和直流系统中,能够在瞬时大能量浪涌发生时提供可靠的钳位保护,保护下游元器件不被过压损坏。07D471K 在能量吸收、峰值冲击能力和低电容特性之间取得平衡,适合电源输入端、直流链路保护以及敏感电子设备的浪涌抑制。
07D471K 设计用于承受工业级脉冲能量,其 8/20 μs 能量吸收 19.7 J 和 1.2 kA 峰值浪涌电流,使其能够在典型雷击或开关瞬变事件中吸收大量能量并将电压限制在安全范围(钳位电压 775 V)以内。压敏电压范围(423–517 V)反映了器件在不同测试电流下的阈值分布,实际选型时应参考具体应用的触发电平和允许工作电压。较低的静态电容(90 pF)保证在高速信号或测控线路中对信号影响最小。
工作电压指标:DC 385 V 和 AC 300 V 表示器件在这些持续电压下可以长期工作而不发生失效,适用于 300 VAC 工业电源侧或 385 V 直流总线(例如部分电力电子、光伏或储能系统的直流侧)作为主要浪涌防护件。
07D471K 为插件(Through-hole)封装,两个引脚间距为 5 mm,适合常规 PCB 布局与手工焊接或波峰焊加工。插件形式使其在维修和更换时便捷,适合需要现场更换保护件的应用场景。外形尺寸与引脚排列需参考厂方完整机械图纸以确保散热与保持距离符合电气安全要求。
品牌:RUILON(瑞隆源),型号:07D471K,封装:插件 P=5 mm。订购时请确认完整型号与批次,以确保压敏电压范围和能量等级满足系统要求。对于不同的电压或能量等级,可参考厂方其它系列或联系供应商获取更合适的替代型号和技术支持。
总结:07D471K 以其 775 V 钳位、19.7 J 能量吸收、1.2 kA 峰值浪涌电流和较低电容特性,为工业与直流系统提供了可靠的瞬态过压保护方案,尤其适合需要插件安装与现场维护的应用。

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.
