TCC0402COG680J500AT是三环电子(CCTC) 推出的贴片多层陶瓷电容(MLCC),专为小型化、高可靠电子设备设计。其核心参数清晰明确,适配多数中低压精密电路需求:
项目 详情 型号全称 TCC0402COG680J500AT 品牌 三环电子(CCTC) 产品类型 多层陶瓷电容(MLCC) 封装规格 0402(英制,对应公制1005,尺寸1.0mm×0.5mm) 容值 68pF(代码“680”:68×10⁰) 精度 ±5%(EIA精度档“J”) 额定电压 50V(直流/交流兼容,最大工作电压50V) 温度系数 C0G(国际标准NP0,±30ppm/℃) 包装形式 标准编带包装(适配自动化贴装)该电容核心优势集中在温度稳定性、低损耗、精度控制三大维度,适配高要求场景:
C0G是MLCC中温度稳定性最优的材质之一,在**-55℃至+125℃** 工作范围内,容值变化量仅±0.3%以内,损耗角正切(tanδ)随温度波动极小。这一特性可避免极端环境下电路参数偏差,尤其适合户外设备、工业控制等场景。
1MHz测试条件下,损耗角正切典型值<0.05%,Q值(品质因数)远高于X7R、Y5V等温敏型电容。高Q值意味着谐振电路、射频滤波中能量损耗低,能提升信号传输效率,减少热积累。
±5%精度(J档)满足精密设备对参数一致性的要求,三环电子的叠层工艺可保证每颗电容偏差控制在标称范围内,批量生产时批次一致性优异,降低电路调试难度。
50V额定电压覆盖5V/12V/24V等主流电源系统,无需额外降额设计即可稳定工作,适配多数消费电子、通信设备的电压需求。
0402封装结合三环成熟工艺,兼顾小型化与可靠性:
封装尺寸仅1.0mm×0.5mm×0.5mm(典型高度),是当前小型化设备的主流选择,可有效减少电路板面积,适配智能手机、可穿戴设备等空间受限产品。
采用先进多层陶瓷叠层技术,电极材料选用高导电率金属,陶瓷介质层均匀性好;通过高温存储(125℃/1000h)、温度循环(-55℃~+125℃/1000次)、耐湿测试(85℃/85%RH/1000h) 等可靠性试验,失效率远低于行业标准。
标准编带包装适配SMT自动化贴装设备,贴装效率高;引脚可焊性符合IPC标准,回流焊后焊点可靠性强,减少生产不良率。
该电容因性能优势,广泛应用于以下领域:
三环电子(CCTC)是国内MLCC龙头企业,拥有20余年研发生产经验,产品覆盖全品类电容。TCC0402COG680J500AT符合:
产品提供完整检测报告与批次追溯,满足客户质量管控需求。
综上,TCC0402COG680J500AT凭借高稳定性、低损耗、小型化 等优势,是消费电子、通信、工业等领域的高性价比选择。
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.
