TCC0402X7R474K100AT是国内知名电子元器件品牌三环(CCTC) 推出的通用型多层陶瓷电容(MLCC),专为低压、小型化电子设备设计,兼具高可靠性与成本效益,广泛应用于消费电子、物联网、小型家电等领域。
该型号MLCC采用0402英制贴片封装(对应公制尺寸约1.0mm×0.5mm),介质类型为X7R,核心参数明确:容值470nF(标识“474”,即47×10⁴pF)、精度±10%(标识“K”)、额定电压10V。产品符合RoHS无铅环保标准,可直接用于主流电子设备批量生产。
容值稳定在470nF,±10%的精度范围(K档)满足绝大多数通用电路需求,无需额外高精度匹配,降低设计复杂度。批量产品参数离散度≤5%,一致性优于行业平均水平。
采用X7R陶瓷介质,温度系数定义为:-55℃~+125℃范围内,容值变化不超过±15%,可适应宽温环境(如车载辅助电路、户外小型设备),避免极端温度下性能波动。
额定电压10V,适用于低压直流电路(3.3V、5V供电系统),电压降额后可长期稳定工作,无击穿风险。
0402封装尺寸紧凑,可显著缩小PCB面积,适配智能手机、智能手环、无线耳机等便携式设备的高密度布局需求,有效降低整机体积。
三环采用成熟的多层陶瓷叠层工艺,电极与介质层均匀分布,确保:
产品电极采用无铅锡膏,符合欧盟RoHS、中国GB/T 26572等环保标准,无有害物质残留,可出口全球市场。
三环作为国内MLCC龙头企业,该型号通过多项权威认证:
该产品凭借小型化、高可靠性与成本优势,成为低压通用电路的主流选型之一,可满足多数中低端电子设备的性能需求。

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.
