FN18N181J500PSG是PSA信昌电陶推出的一款0603封装贴片多层陶瓷电容(MLCC),属于C0G(NP0)材质系列,专为中低压精密电子电路设计,兼具小型化、高稳定性与低损耗特性。
型号编码拆解:
标称容值180pF,精度等级为J档(±5%),无需额外匹配调整即可满足常规精密电路对容值一致性的要求,尤其适合对容值漂移敏感的高频/振荡电路。
直流额定电压50V,可稳定工作在0~50V电压范围,覆盖多数中低压电子系统(如消费电子、工业控制)的供电需求,无需降额使用(常规降额系数1.2倍时,实际耐压可达60V)。
采用C0G(NP0)陶瓷材质,温度系数≤±30ppm/℃(工作温度范围-55℃~125℃),是目前陶瓷电容中温度稳定性最高的材质之一——容值随温度、电压变化极小,几乎无老化效应。
0603英制封装(公制1.6mm×0.8mm×0.8mm),引脚间距0.5mm,体积仅为传统插件电容的1/10,适配高密度PCB布局与轻薄化产品设计。
对比X7R(±15%容值漂移)、Y5V(±82%容值漂移)等材质,C0G的容值漂移可忽略,能在极端温度(如车载-40℃85℃、工业-55℃125℃)下保持电路性能一致性,避免信号失真。
高频损耗极低(DF≤0.15%@1kHz),Q值(品质因数)可达1000+(1MHz下),适合射频(RF)、振荡、滤波等高频电路,减少信号衰减与干扰。
PSA信昌电陶采用成熟的多层陶瓷叠层工艺,产品经过高温老化(125℃×1000h)、湿度循环(85℃/85%RH×500h)、振动测试(10~2000Hz) 等严格验证,平均寿命超10万小时,符合汽车电子(小信号场景)与工业级应用要求。
符合RoHS2.0、REACH等国际环保标准,无铅无卤,适配全球市场准入需求,避免环保合规风险。
WiFi 6、蓝牙5.0、LoRa等无线通信模块中的滤波、耦合电容,利用低损耗特性减少信号干扰与传输损耗,提升通信稳定性。
示波器、信号发生器、频谱分析仪等的振荡回路、滤波网络,C0G的高稳定性确保测量精度不受温度影响,避免仪器误差。
智能手机、平板电脑、智能手表的射频前端、天线匹配电路,0603封装适配轻薄化设计,满足便携设备的高密度布局需求。
PLC、传感器接口、电机驱动的滤波电容,宽温性能与高可靠性减少工业环境(振动、温湿度变化)下的故障风险,提升系统稳定性。
车载信息娱乐系统、胎压监测模块的小信号处理电路,满足车载温度(-40℃~85℃)与振动要求,保障汽车电子系统的长期稳定运行。
PSA信昌电陶是国内MLCC领域的龙头企业之一,拥有20余年陶瓷电容研发与生产经验,产品覆盖C0G、X7R、Y5V等全系列材质,产能与品质稳定。
FN18N181J500PSG通过以下认证与测试:
公制:1.6mm(长)×0.8mm(宽)×0.8mm(厚);
引脚焊盘:0.3mm×0.5mm(典型值),符合IPC-A-610标准。
兼容回流焊(温度曲线:预热150180℃,峰值240260℃)、波峰焊工艺,贴装精度可达±0.1mm,适配自动化SMT生产线。
常规包装为卷带(Tape & Reel),每盘3000~5000pcs,适合批量自动贴装,减少人工成本与元件损耗。
综上,FN18N181J500PSG凭借C0G材质的高稳定性、低损耗特性,以及0603封装的小型化优势,成为精密电子、射频通信、工业控制等领域的理想电容选择,可有效提升电路性能与产品可靠性。
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.
