FM43N103J631EEG是PSA信昌电陶推出的一款中高压C0G温度系数多层陶瓷电容器(MLCC),凭借稳定的电气性能、高压耐受能力与紧凑封装,广泛适用于工业控制、电源滤波等对容值精度要求较高的场景。
这款电容属于PSA信昌电陶的高压MLCC产品线,型号中“FM43”为品牌系列标识,“N103J631EEG”对应具体参数与封装规格。PSA(信昌电陶)作为国内专业陶瓷元件制造商,专注于MLCC、高压陶瓷电容的研发与生产,产品覆盖消费电子、工业、新能源等领域,以“高可靠性、宽温度适应性”为核心优势,通过多项行业认证(如RoHS、AEC-Q200部分型号)。
标称容值为10nF(10³pF),精度等级为**±5%**(型号中“J”代表该精度),满足大多数需要中等精度的电路需求,无需额外校准即可稳定工作。
额定直流电压为630V(型号中“631”为厂商标注习惯),属于中高压MLCC范畴,可承受较高工作电压,避免过压击穿风险,适配中高压电路的电压波动场景。
采用C0G(NP0)温度系数,容值随温度变化极小(典型变化率≤±30ppm/℃),在-55℃~+125℃宽温范围内保持容值稳定,远优于X7R、Y5V等温度系数系列,是对容值稳定性要求高的电路首选。
采用1812表面贴装(SMD)封装(英制尺寸,对应公制约4.5mm×3.2mm),适配自动化贴装生产线,安装效率高,适合高密度PCB布局。
参考PSA标准规格,典型尺寸为:长4.5±0.2mm、宽3.2±0.2mm、厚度1.0±0.1mm,体积紧凑,可有效节省PCB空间。
采用镍电极(Ni)+ 无铅端接(符合RoHS指令),焊接兼容性好,支持回流焊、波峰焊等工艺,长期使用中不易出现端接脱落问题。
C0G系列的核心优势在于“零温度漂移”,容值随温度变化可忽略,即使在极端温度下(如工业现场的低温或高温环境),也能保证电路性能稳定。
高频损耗低(DF≤0.15%@1kHz),谐振频率高,适合射频电路、高频滤波等应用,信号失真小,不影响高频信号传输质量。
产品经过高温老化、湿度循环、机械振动等多项可靠性测试,满足工业级标准,使用寿命可达10万小时以上,可应对复杂工作环境的长期考验。
FM43N103J631EEG凭借高压耐受、稳定容值、紧凑封装等特性,成为中高压电路中C0G系列MLCC的优质选择,适用于多领域对可靠性与稳定性要求较高的场景。
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.
