TCC0402COG331J500AT是三环集团(CCTC) 推出的高频稳定型MLCC,核心参数与封装匹配如下:
COG(NP0)温度系数为**±30ppm/℃**,在-55℃至125℃的宽温范围内,容值变化可忽略(实际测试变化率≤0.1%),解决了普通陶瓷电容温漂导致的性能波动问题。
介质损耗角正切值(DF)典型值≤0.15%,高频(1MHz)下阻抗特性稳定,适合100MHz以内的射频、振荡电路,避免信号失真或能量损耗。
0402封装体积仅1.0×0.5×0.5mm(典型),适配便携式设备的高密度布局;兼容常规SMT贴装工艺(贴装偏差允许±0.05mm),可实现自动化批量生产。
额定电压50V满足大部分低压电路需求,MLCC无极性结构抗干扰能力强,长期工作(1000小时@125℃)容值漂移≤0.5%,符合工业级可靠性要求。
作为晶振、压控振荡器(VCO)的负载电容,利用COG的温度稳定性保证振荡频率精准(如手机射频模块的时钟源),避免温漂导致的通信误码。
在RC定时电路(如MCU复位电路)、LC谐振电路(如射频滤波器)中,稳定容值确保定时精度(误差≤0.5%)和谐振频率稳定。
实际工作电压需低于额定电压50V,建议保留10%-20%裕量(如工作电压≤40V),避免过压导致电容击穿或老化加速。
若应用环境超出-55℃125℃(如高温航空场景),需更换其他温度系数电容;工业场景(-40℃85℃)本产品完全适配。
0402封装对贴装精度要求较高,需使用高精度贴片机(如富士NXT系列),避免桥连、立碑等缺陷;回流焊温度需符合三环推荐曲线(峰值245℃±5℃)。
本产品为±5%精度(J档),若应用需更高精度(如≤±1%),需选择F档(±1%)或更高级别,但成本会相应提升。
三环集团(CCTC)是国内MLCC行业龙头,TCC系列产品采用自主研发的介质材料,批量一致性好(容值离散度≤0.3%),产能稳定(月产能超10亿只),可满足中小批量至大规模生产需求;产品提供1年质保,支持样品测试与技术咨询。
该产品凭借稳定的温度特性、低损耗和小型化优势,成为消费电子、工业控制等领域高频电路的主流选型之一。

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.
