FV32X472K202EGG是信昌电陶(PSA) 推出的工业级高压多层陶瓷贴片电容(MLCC),针对高电压、宽温域场景设计,核心参数精准匹配电源滤波、EMI抑制等高压电路需求。具体参数如下:
编码中“FV32”为PSA高压MLCC系列标识(对应1210封装),“EGG”为端电极与包装代码(无铅端电极+卷带包装)。
额定2000V DC满足多数工业高压电路需求,内部多层陶瓷叠层结构分散电场应力,避免击穿风险;短时间过压(≤2.2kV)耐受能力优于同容值电解电容,适配电路瞬态尖峰场景。
X7R温度系数使产品在-55℃至+125℃范围内,容值波动控制在±15%以内,无需额外温度补偿,适配户外设备、高温工业环境(如变频器、光伏逆变器)。
1210封装尺寸紧凑(厚度约1.0mm±0.1mm),兼容回流焊、波峰焊工艺,焊接面积充足(端电极宽0.3mm),降低虚焊风险,适合大规模自动化组装。
无极性设计简化布线,高频阻抗低(1MHz下阻抗≤10Ω),适合高压电路EMI滤波、纹波抑制,性能远优于铝电解电容(高频特性差)。
公制规格:3.20mm(长)×2.50mm(宽)×1.0mm(厚),公差±0.2mm/±0.1mm,满足PCB高密度布局,同时保证机械强度。
内部采用高介电常数陶瓷介质与镍电极交替叠层,流延工艺成型,既提高容值密度(1210封装实现4.7nF高压容值),又降低介质损耗(tanδ≤0.02@1kHz)。
端电极采用“镍底层→铜中间层→锡银表层”三层结构,符合RoHS 2.0与REACH标准,焊接兼容性好,避免铅污染。

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.
