TCC0402COG1R0B500AT 贴片陶瓷电容(MLCC)产品概述

一、产品基本属性

TCC0402COG1R0B500AT是三环电子(CCTC) 推出的一款高精度多层陶瓷贴片电容(MLCC),核心参数清晰匹配工业与消费电子的精密需求:

  • 封装规格:0402英制(公制1005),尺寸为1.0mm×0.5mm×0.5mm(典型厚度),适配高密度贴装;
  • 容值精度:1pF(料号“1R0”表示1×10⁰ pF),C0G类电容默认精度可达±0.1pF,批次离散性≤±0.05pF;
  • 额定电压:50V直流(料号“B500”对应电压等级,交流电路需降额使用);
  • 温度系数:C0G(IEC标准分类,美军标NP0等效),温度范围-55℃~+125℃,容值变化率≤±30ppm/℃;
  • 品牌标识:三环电子(CCTC)旗下“TCC”系列高精度电容,符合无铅环保要求。

二、核心性能优势

1. 超宽温域的容值稳定性

C0G温度系数是该产品的核心竞争力——在-55℃至+125℃范围内,1pF电容的容值波动≤3fF(即±0.03%),远优于X7R(±15%)、Y5V(±20%)等电容,可避免温度变化对精密电路(如晶振、射频)的干扰。

2. 低损耗与高频适配性

  • 损耗因子(DF)≤0.15%(1kHz测试),等效串联电阻(ESR)在100MHz时仅约1Ω;
  • 支持2.4GHz、5GHz等主流射频频段,可减少信号传输衰减,提升射频电路的接收灵敏度(典型提升0.5~1dB)。

3. 小型化与贴装兼容性

0402封装体积紧凑,适配富士、西门子等自动化贴片机,贴装精度可达±0.05mm;兼容无铅回流焊工艺(峰值温度240~250℃,持续时间≤30s),符合RoHS 2.0、REACH环保标准。

4. 批量一致性与可靠性

三环采用全自动化叠层工艺,批次间容值、电压参数一致性好;绝缘电阻≥10⁹Ω(25℃/50V测试),可保障长期稳定运行。

三、典型应用场景

1. 晶振负载电容

用于石英晶振电路(如通信基站、工业PLC),容值稳定可确保振荡频率偏差≤±10ppm,满足时钟精度要求。

2. 射频(RF)前端电路

适配手机、WiFi模块的耦合、滤波环节,低损耗特性减少信号衰减,提升2.4GHz频段的信号覆盖范围。

3. 精密模拟仪器

在医疗监护仪(心电、血氧采集)、示波器中用于信号耦合,避免容值波动干扰微弱信号,保障测量精度(如心电信号精度±0.1mV)。

4. 小型化消费电子

智能手机射频天线匹配、智能手表传感器滤波,0402封装缩小电路尺寸,50V电压满足中低压电源滤波需求。

四、可靠性与品质管控

1. 权威认证

通过ISO 9001质量管理体系、RoHS 2.0(无铅无镉)、REACH(SVHC合规)认证,符合欧盟、美国市场准入要求。

2. 环境可靠性测试

  • 高温寿命:125℃/50V下1000小时,容值变化≤±1%,绝缘电阻≥10⁹Ω;
  • 湿热测试:85℃/85%RH下1000小时,容值变化≤±1.5%;
  • 机械可靠性:振动(10~2000Hz,2g)、冲击(100g峰值)后无开路短路,容值变化≤±2%。

3. 批次管控

每批次抽样比例≥5%,检测容值、DF、ESR、电压等参数,合格率≥99.9%。

五、选型与使用注意事项

  1. 电压降额:直流电路实际电压≤40V(80%降额),交流峰值电压≤35V(70%降额);
  2. 贴装工艺:回流焊温度曲线需匹配三环规范,避免高温损坏内部结构;
  3. 选型区分:若需储能(电源滤波)选X7R/X5R,若需高压(≥100V)选对应高压系列,本产品优先用于精密、高频场景。

该产品凭借高精度、高稳定性与小型化优势,成为通信、医疗、消费电子等领域的优选电容之一。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
