FN18N272J500PBG 贴片多层陶瓷电容（MLCC）产品概述
FN18N272J500PBG是PSA信昌电陶推出的一款高频低损耗型贴片多层陶瓷电容（MLCC），以优异的温度稳定性、低损耗特性和小型化封装，成为精密电子电路中的核心被动元件之一。
一、产品核心身份与应用定位
该型号属于C0G材质（IEC标准NP0） MLCC，专为对容值稳定性、高频性能要求严苛的电路设计——区别于X7R、Y5V等温度特性较差的材质，可在宽温范围内保持容值恒定，是振荡电路、射频匹配网络等场景的首选。
二、关键电气性能参数解析
参数项 具体指标 说明 标称容值 2.7nF（272pF） EIA代码"272"对应27×10²pF=2.7nF 容值精度 ±5%（代码J） 满足精密电路的一致性要求 额定电压 50V DC 适用于低压直流电路，无过压风险 温度系数 C0G（0±30ppm/℃） 温度范围-55℃~125℃，容值变化≤±0.5% 损耗角正切（DF） ≤0.15%（1kHz/25℃） 高频下信号损耗极小，适合射频应用 直流偏置效应 无（C0G材质特性） 容值不随直流电压加载而漂移三、封装与物理特性说明
- 封装规格：英制0603（公制1608），即长0.06英寸（1.524mm）、宽0.03英寸（0.762mm），是小型化电子设备的常用封装；
- 尺寸参数：典型值L=1.6±0.15mm，W=0.8±0.15mm，T=0.8±0.1mm（厚度因生产批次略有差异）；
- 电极与焊接：两端采用银钯（Ag-Pd）合金电极，兼容回流焊、波峰焊工艺，焊接可靠性高；
- 封装材料：陶瓷基体+环氧树脂保护层，耐机械应力与环境腐蚀。
四、核心性能优势
- 超宽温度稳定性：C0G材质的容值随温度变化可忽略，对比X7R材质（±15%变化），可确保振荡电路频率精度、射频电路匹配性能稳定；
- 低损耗高频特性：DF≤0.15%，在1GHz以上频段仍保持低损耗，减少信号衰减，提升射频链路效率；
- 无直流偏置效应：不同于高介电常数材质（如X7R），C0G容值不受直流电压影响，避免电路性能漂移；
- 高可靠性：额定电压50V远低于材质耐压极限，长期工作寿命长；宽温范围（-55~125℃）满足工业级环境要求。
五、典型应用场景
- 高频振荡电路：晶体振荡器、压控振荡器（VCO）的谐振网络，保证频率精度；
- 射频（RF）模块：蓝牙、WiFi、5G通信模块中的耦合电容、匹配网络、滤波电路；
- 精密模拟电路：运算放大器反馈网络、高精度滤波电路，提升信号质量；
- 工业控制设备：PLC、传感器接口电路，适应宽温环境；
- 消费电子：智能手机、智能穿戴的射频前端、音频电路，适配高密度PCB设计。
六、品牌与质量背书
PSA信昌电陶是国内MLCC领域的资深厂商，拥有完整的研发、生产体系，该型号通过：
- 环保认证：RoHS 2.0、REACH，符合欧盟环保要求；
- 可靠性认证：部分批次满足AEC-Q200（汽车电子标准），可用于汽车级场景（需确认具体规格）；
- 工艺优势：采用高精度叠层工艺，容值一致性达±2%（高于标称精度），批次间差异极小。
该型号凭借稳定的性能与小型化设计，广泛应用于消费电子、工业控制、射频通信等领域，是替代进口同类产品的高性价比选择。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
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.
