FV55X472K202EFG是PSA信昌电陶推出的工业级高压多层陶瓷贴片电容(MLCC),针对高压、宽温环境下的稳定应用需求设计,核心参数清晰明确:
宽温容量稳定性
X7R温度系数确保产品在极端温度下性能一致:-55℃低温环境中容量衰减≤15%,125℃高温下容量变化≤±15%,满足北方户外工业设备、高温车间自动化装置的可靠性需求。
高压耐受能力
额定电压2000V DC,可长期稳定工作在额定工况,同时具备1.5倍额定电压的短时过压裕量(符合IEC 60384-14标准),降低高压应用中的击穿风险。
小型化适配性
2220封装体积仅为传统插件高压电容的1/5左右,可显著缩小设备体积,适配新能源充电桩、医疗成像设备等高密度集成场景,同时支持自动化贴装,提升生产效率。
低损耗与可靠性
介质损耗(DF值)典型值≤1%,减少能量损耗;端电极镍层厚度≥2μm、锡层厚度≥5μm,焊接润湿性≥90%,且镍层可阻挡锡向陶瓷介质扩散,避免介质劣化,延长使用寿命。
机械强度优化
2220封装符合IPC J-STD-001标准,可承受工业环境中的震动(10~2000Hz,加速度2g)和冲击(峰值加速度100g,持续1ms),满足PLC、伺服驱动器等设备的抗振需求。
介质材料升级
采用钛酸钡基陶瓷介质,经高温烧结工艺制成,介质均匀性好,减少局部电场集中;抗湿性符合JESD22-A101标准(85℃/85%RH环境下1000h后性能衰减≤5%)。
端电极可靠性设计
镍锡双层镀层解决了纯锡镀层易硫化的问题,同时提升焊接强度,避免高温回流焊时的“立碑”“虚焊”等缺陷。
工业开关电源
用于光伏逆变器、变频器的高压直流母线滤波,稳定电压波动,抑制EMI干扰,提升电源效率。
医疗设备辅助电路
如CT、X光机的高压控制模块,提供稳定的高压耦合,满足医疗设备对可靠性、安全性的严格要求。
新能源充电桩
快充模块中的高压储能、电压分压环节,适配400V~1000V快充场景的高压工作环境。
工业自动化设备
PLC、伺服驱动器的高压接口电路,实现高压信号耦合与滤波,确保设备在工业现场的稳定运行。
通信基站高压模块
基站电源系统的高压配电环节,抑制电磁干扰,提升电源系统的抗干扰能力。

Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
