FV55X154K102EHG是PSA信昌电陶推出的高压贴片多层陶瓷电容(MLCC),针对中高压电子电路的滤波、储能及电磁干扰(EMI)抑制需求设计,具备1kV额定电压、150nF容值、X7R温度系数等核心特性,采用2220封装适配自动化贴装工艺,广泛应用于工业电源、新能源、医疗设备等领域。
该产品属于高压专用MLCC,区别于普通低压MLCC,采用多层叠层陶瓷介质结构,通过优化介质配方与端电极设计,兼顾高压耐量与容值密度。制造商PSA信昌电陶是国内专注陶瓷电容研发的高新技术企业,产品覆盖消费电子、工业、新能源等多领域,具备成熟的量产与质量控制体系。
标称容值为150nF(对应代码“154”,即15×10⁴pF),精度为**±10%**,满足多数滤波电路的容值偏差要求,无需额外并联电容补偿。
直流额定电压为1kV,可承受短期过压(如电路瞬态尖峰电压),为高压电路提供充足安全余量(如市电整流后310V直流母线,余量达3倍以上)。
采用X7R陶瓷介质,工作温度范围为**-55℃~+125℃**,在此范围内容值变化不超过±15%,温度稳定性优于Y5V等低成本材质,适合环境温度波动较大的工业场景。
X7R介质兼具较高容值密度与宽温可靠性,平衡了“大容值需求”与“高压耐量”的矛盾,避免C0G(超稳但容值小)或Y5V(容值大但温漂大)的局限性。
采用2220英制贴片封装,对应公制尺寸约为:
端电极采用镍-锡(Ni-Sn)合金镀层,适配回流焊、波峰焊等标准贴片工艺,端电极附着力符合IEC 60384-1国际标准,焊接后无脱落、开裂风险。封装尺寸紧凑,在保证1kV耐量与150nF容值的前提下,比同容值低压电容节省约30%PCB空间,适合高密度电路设计。
PSA信昌电陶对该产品进行多项可靠性测试,确保长期稳定工作:
同时符合RoHS 2.0、REACH等环保法规,可用于出口产品。
FV55X154K102EHG以可靠的高压性能、宽温适应性与紧凑封装,成为工业电源、新能源等领域中高压电路的优选无源元件,可满足不同场景的性能与可靠性要求。

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.
