CCTC0402X7R104J500AT 贴片多层陶瓷电容(MLCC)产品概述

一、产品核心身份与定位

CCTC0402X7R104J500AT是三环电子(CCTC)推出的通用型贴片多层陶瓷电容,针对消费电子、通信、工业控制等领域的常规电路需求设计。该产品兼顾小型化、温度稳定性与成本效益,是电子设备中电源滤波、信号耦合、去耦等场景的常用选型,属于中低压(50V)、中精度(±5%)的基础被动元件。

二、关键参数详细解析

从型号可直接对应核心参数,各参数意义如下:

  • 封装尺寸:0402(英制代码,对应公制1005,实际尺寸1.0mm×0.5mm),适合高密度PCB布局,满足便携设备小型化需求;
  • 容值:104(即10×10⁴ pF=100nF),为电源滤波、耦合的常用容值范围,覆盖多数低/中功率电路;
  • 精度等级:J(±5%),行业常规精度,可满足大多数电路的匹配与性能要求,无需高精度场景的额外成本;
  • 额定电压:50V(直流额定),适用于中低压直流电路;交流电路需按额定电压的1/2~1/3降额(如AC25V以下),避免介质击穿;
  • 温度系数:X7R,对应温度范围-55℃~+125℃,容值变化≤±15%,是温度稳定性较好的陶瓷介质类型,优于Y5V等低稳定介质。

三、材料与结构特性

该产品采用多层陶瓷叠层结构,核心材料与结构设计如下:

  • 介质层:X7R钛酸钡基陶瓷,兼具容值密度与温度稳定性——既避免NPO(高稳定但低容)的容量局限,也优于Y5V(高容但温漂大)的稳定性;
  • 内电极:镍基贱金属电极(BM),符合环保要求且成本可控,替代传统贵金属电极(如银钯);
  • 外电极:三层结构(镍层+锡铅/纯锡层),无铅版本满足RoHS指令,焊接兼容性好,可适配回流焊、波峰焊等工艺。

该结构经三环电子常规可靠性测试(如高温寿命、湿度循环),可满足多数民用/工业场景的使用寿命要求。

四、典型应用场景

因参数均衡,该产品广泛应用于以下领域:

  1. 消费电子:手机、平板、智能穿戴的电源滤波、音频耦合电路;
  2. 通信设备:路由器、交换机、基站射频前端的信号去耦与耦合;
  3. 工业控制:PLC(可编程逻辑控制器)、传感器模块的电源稳定与信号滤波;
  4. 小型家电:智能插座、遥控器等低功耗设备的辅助电路。

注:若应用于汽车电子等严苛场景,需确认是否符合AEC-Q200认证(本产品未明确标注,需向厂商核实)。

五、性能优势与使用注意事项

5.1 核心优势

  • 小型化适配:0402封装可大幅节省PCB空间,适合便携设备与高密度设计;
  • 温度稳定性:X7R介质在-55℃~+125℃范围内容值变化≤±15%,满足户外或工业宽温环境;
  • 成本效益:常规参数与成熟工艺,批量采购成本可控,适合大规模应用;
  • 可靠性:三环品牌的MLCC经过基础可靠性验证,可支撑常规电子设备的5~10年使用寿命。

5.2 使用注意事项

  • 电压降额:交流电路必须降额使用(如额定50V对应AC≤25V),否则易导致介质击穿;
  • 焊接工艺:回流焊峰值温度需控制在230℃~250℃,焊接时间≤60秒,防止介质开裂;
  • 机械应力:0402封装较小,焊接后避免过度弯折PCB,防止电容本体开裂;
  • 吸潮防护:未开封产品需存储于干燥环境(温度25±5℃,湿度≤60%),开封后建议6个月内用完,避免吸潮导致焊接爆板。

六、包装与存储规范

  • 包装形式:采用8mm或12mm卷带(Tape & Reel)包装,每盘常规数量10000个,适合自动化贴装;
  • 存储要求:未开封产品存储期1年,开封后需尽快使用(建议6个月内);存储环境需远离高温、高湿与腐蚀性气体,避免影响焊接性能。

该产品是电子设计中“均衡型MLCC”的典型代表,可满足多数常规电路的核心需求,是工程师选型时的高性价比选项。

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
