CL31Y225KCHVPNE 为 SAMSUNG(三星)出品的一款贴片多层陶瓷电容(MLCC),标称容量 2.2 μF,精度 ±10%,额定电压 100 V,介质为 X7S,封装 1206(英制),适用于对体积、耐压和温度性能有中等稳定性要求的电源滤波与能量缓冲场合。
X7S 介质相较于 C0G/NP0 有更高的体积效率(单位体积容值更大),但属于非线性陶瓷,存在温度随动、老化和直流偏压时电容量下降等特性,需要在设计中予以考虑。
建议对关键设计进行以下验证:实装后在工作电压下测量有效容值(DC-bias 下)、等效串联电阻(ESR/tanδ)、漏电流/绝缘电阻及高低温循环测试。对可靠性要求高的应用,向供应商索取完整的数据手册、可靠性测试记录与焊接工艺参数。
总结:CL31Y225KCHVPNE 在体积与额定电压之间提供较高的容值密度,适用于对中高压滤波和去耦有需求的产品,但在使用时需重点考虑 X7S 的 DC-bias、温漂与老化特性,合理预留裕量并按厂方工艺指导进行 PCB 布局与回流焊接。若需更严格的温度稳定性或更小的偏压衰减,建议评估其它介质或更高额定电压的备选件,并参考原厂完整数据表以完成最终验证。

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.
