TCC0805COG181J500BT是三环电子(CCTC)推出的0805封装高频稳定型贴片陶瓷电容,属于NPO(C0G)介质系列。该产品针对对容值温度稳定性、信号损耗要求较高的电子电路设计,兼顾体积小型化与电气性能可靠性,是消费电子、射频通信、工业控制等领域的通用型基础元件。
容值标称值为180pF(型号中“181”表示18×10¹=180pF),精度等级为**±5%(J档)**,批量生产中参数一致性符合IEC 60384-8等国际标准,可满足多数电路对容值偏差的要求,无需额外冗余设计。
直流额定电压为50V,可覆盖中低压电路(如12V、24V电源滤波、信号耦合)的电压需求;工作温度范围通常为**-55℃~125℃**(C0G介质典型值),宽温环境下容值漂移极小,适合极端温度场景。
采用C0G(NPO)陶瓷介质,温度系数≤±30ppm/℃(远低于X7R等介质),容值随温度、电压变化可忽略;介质损耗角正切(DF)典型值≤0.15%,高频信号传输时能量损耗低,尤其适合射频电路应用。
封装为0805英制规格(对应公制2012,尺寸2.0mm×1.2mm),符合SMT贴片生产标准,可兼容多数PCB板的贴装布局,尤其适合便携设备的高密度设计。
产品厚度为0.6mm,属于常规贴片电容厚度,焊接时不易出现立碑、虚焊等问题,适配回流焊、波峰焊等工艺,生产效率高。
NPO介质无极性,安装方向无限制;端电极采用镍-锡镀层(无铅,符合RoHS 2.0标准),焊接兼容性好,可与常见焊料(Sn-Ag-Cu)匹配,长期可靠性有保障。
适用于蓝牙、WiFi、4G/5G射频前端电路(如滤波器、振荡器、信号耦合),C0G的低损耗与温度稳定性可保证信号传输质量,避免频率漂移影响通信稳定性。
在音频处理、传感器信号调理、运算放大器滤波等电路中,容值稳定特性可减少温度变化对信号精度的影响,提升电路线性度,尤其适合对信号失真要求高的场景。
工作温度范围宽,可靠性高,可用于工业PLC、电机驱动、汽车仪表盘等环境(-40℃~85℃),满足工业级产品的稳定性要求,降低维护成本。
0805封装体积小,适合智能手机、平板电脑、智能穿戴设备的电源滤波、射频模块,提升产品集成度,同时保证性能稳定。
三环电子(CCTC)是国内陶瓷电容领域的主流厂商,产品通过ISO 9001质量管理体系认证,符合RoHS、REACH等环保法规;TCC0805COG系列经高温存储(125℃/1000h)、温度循环(-55℃~125℃/1000次)等可靠性测试,失效率低,批量应用时一致性好,可降低电路调试成本。
该产品以“高频稳定+小体积+高可靠性”为核心优势,是电子设计中替代进口同规格产品的高性价比选择。

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.
