14D470K 是 RUILON(瑞隆源)品牌的一款插件式压敏电阻,封装为 D17×8mm,针距 P=7.5mm,适用于低电压直流/交流系统的浪涌抑制。该器件标称压敏电压范围为 43V~53V,在规定浪涌条件下的钳位电压约为 93V,能够在瞬态冲击时吸收较大能量,保护下游电路免受过电压损害。
选择时应关注:最大脉冲电流与能量是否满足最恶劣工况;工作电压需高于系统正常电压;静态电容对信号/控制线影响是否可接受。若需更高能量或更低钳位电压,可选能量等级更高或压敏电压更低的型号;若希望更小体积或更低电容,可考虑表贴型或小尺寸器件,同时注意额定电流与能量匹配。
总结:14D470K(RUILON)以其 15J 的能量吸收、1kA 的瞬态承受能力和插件式 D17×8mm 封装,适合用于低压电源与输入端的浪涌防护。在设计中应结合具体工作电压、冲击能量与安装条件合理选型与布局,以达到稳定可靠的防护效果。

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.
