TCC0402X7R102J500AT 贴片多层陶瓷电容(MLCC)产品概述

一、产品基本属性与核心参数

TCC0402X7R102J500AT是三环电子(CCTC) 推出的一款小型化贴片多层陶瓷电容(MLCC),型号各部分对应核心属性如下:

  • 前缀TCC:三环电子品牌标识;
  • 0402:英制封装尺寸(对应公制1005);
  • X7R:EIA标准温度系数介质;
  • 102:容值代码(10×10²pF=1nF);
  • J:精度代码(±5%);
  • 500:直流额定电压(50V);
  • AT:系列标识(无铅环保型)。

核心参数表:

参数项 规格值 标称容值 1nF(102pF) 精度 ±5%(J级) 额定电压(DC) 50V 温度系数 X7R(-55℃~+125℃,容变±15%) 封装 0402(1005公制) 环保认证 RoHS 2.0、无铅(Pb-free)

二、封装与物理特性

该产品采用0402贴片封装,适配自动化SMT生产线,物理尺寸符合行业标准:

  • 公制尺寸:长1.0±0.1mm × 宽0.5±0.1mm;
  • 典型厚度:0.5±0.05mm(依生产批次略有差异);
  • 电极设计:两端镀锡/镍电极,焊盘尺寸与0402封装匹配,焊接附着力强,可通过回流焊、波峰焊工艺安装。

封装优势:体积小、重量轻,适合便携设备、高密度电路板的集成需求。

三、电气性能详解

3.1 容值与精度

标称容值1nF,精度±5%,满足多数电路的滤波、耦合、旁路等功能需求,无需额外校准即可稳定工作。

3.2 电压特性

直流额定电压50V,可承受短期1.5倍额定电压(75V)过压,避免电路瞬态电压冲击损坏;交流工作电压需根据频率降额(如1kHz时交流额定电压约10V)。

3.3 绝缘性能

  • 25℃时绝缘电阻(IR)典型值≥10⁹Ω;
  • 125℃高温下IR≥10⁸Ω,无明显漏电,保证电路信号完整性。

3.4 损耗与频率特性

  • 损耗角正切(DF):1kHz、25℃条件下≤2%,高频损耗低,适合信号传输场景;
  • 谐振频率:典型值约100MHz,谐振点以下表现为纯电容特性,可用于高频滤波(如射频模块)。

四、X7R介质的温度适应性

X7R是钛酸钡基陶瓷介质,核心特点为宽温稳定+中等容值:

  • 温度范围:-55℃至+125℃,覆盖多数电子设备的工作环境(如工业控制、汽车周边设备);
  • 容值变化:相对于25℃,容值漂移控制在±15%以内,优于Y5V(±20%以上)等高容值介质,避免极端温度下电路性能波动。

注:X7R介质的容值温度系数曲线平缓,无明显“拐点”,适合对温度稳定性有要求但无需高精度(如±1%)的场景。

五、典型应用场景

该产品因小体积、宽温特性,广泛应用于:

  1. 消费电子:智能手机、蓝牙耳机、智能手环的电源滤波(LDO输出去耦)、音频信号耦合;
  2. 小型工业设备:传感器节点、小型PLC的信号处理电路滤波;
  3. 通信模块:WiFi、蓝牙模块的射频滤波、电源去耦;
  4. 车载周边:非汽车级要求的车载充电器、后视镜控制电路(需确认AEC-Q200认证,该型号暂未标注)。

六、品牌与可靠性保障

三环电子(CCTC)是国内MLCC领域的主流厂商,该产品具备以下可靠性优势:

  • 环保合规:符合欧盟RoHS 2.0标准,无铅设计,避免重金属污染;
  • 可靠性测试:经过高温存储(125℃/1000h)、温度循环(-55℃~+125℃/1000次)、湿度试验(85℃/85%RH/1000h)等验证,故障率低于行业平均水平;
  • 质量控制:自动化生产+全参数检测(容值、电压、绝缘电阻),每批次合格率≥99.9%。

七、选型注意事项

  1. 需确认电路工作电压是否低于50V DC(交流需降额);
  2. 若对温度稳定性要求极高(如±1%),需选择COG/NPO介质;
  3. 汽车级应用需确认产品是否通过AEC-Q200认证(该型号未标注)。

综上,TCC0402X7R102J500AT是一款性价比高、适配性强的小型MLCC,适合多数中低端电子设备的通用滤波/耦合需求。

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
