TCC0805X7R301K500DT 贴片多层陶瓷电容(MLCC)产品概述

TCC0805X7R301K500DT是三环电子(CCTC)推出的通用型贴片多层陶瓷电容(MLCC),采用0805标准封装,专为中低压电路的滤波、耦合、旁路等场景设计,兼具容量稳定性与高可靠性,广泛适配消费电子、工业控制等领域。

一、产品基本信息与型号解析

该产品为0805封装MLCC,型号各段含义清晰:

  • TCC:三环电子(CCTC)品牌代码;
  • 0805:英制封装尺寸(0.08英寸×0.05英寸,公制2.0mm×1.25mm);
  • X7R:陶瓷介质类型,代表温度特性;
  • 301:容值标识(前两位“30”为有效数,第三位“1”为倍率10¹,即30×10¹=300pF);
  • K:容值精度(±10%);
  • 500:直流额定电压(50V);
  • DT:标准带式编带包装代码(适配自动化贴装)。

二、核心性能参数深度解析

1. 容值与精度

容值为300pF,精度±10%(K档),满足大多数通用电路对容量偏差的要求(无需高精度场景下可降低成本)。容值采用“三位数法”标识,是电子行业通用标准,便于快速识别。

2. 额定电压与降额要求

直流额定电压为50V,是核心电压规格:

  • 直流工作电压建议不超过40V(80%降额),避免长期过压导致介质老化;
  • 交流应用需进一步降额(通常≤35V,70%降额),因陶瓷电容交流阻抗随频率变化,需结合实际电路频率调整。

3. 温度特性(X7R介质)

X7R为钛酸钡基陶瓷介质,温度特性表现为:

  • 工作温度范围:-55℃~+125℃;
  • 温度范围内容值变化:ΔC/C ≤±15%(比Y5V稳定,比C0G略差但容量密度更高);
  • 适合环境温度波动较大的场景(如工业控制、车载电子),避免容值漂移影响电路性能。

三、材料与封装工艺特性

1. 介质与电极材料

  • 介质:X7R陶瓷,介电常数(εr)约1000~2000,可在小封装内实现300pF容量,兼顾体积与性能;
  • 电极:采用镍基内电极+无铅外电极,耐焊接热性能优异,符合RoHS环保要求。

2. 封装与贴装兼容性

  • 0805封装:尺寸公差符合IPC-J-STD-001标准(长度2.0±0.1mm,宽度1.25±0.1mm,厚度0.8±0.05mm),适配绝大多数自动化贴装设备;
  • 包装方式:DT代码对应12mm宽带式编带,每盘4000个,便于SMT生产线高效上料。

四、典型应用场景

该产品因容量、电压与温度特性平衡,广泛应用于:

  1. 电源滤波:DC-DC转换器输出端滤波、线性电源稳压后滤波,消除中高频噪声;
  2. 信号耦合:音频电路(如手机听筒/麦克风耦合)、射频低端电路(10MHz以下)信号耦合;
  3. IC旁路电容:微控制器(MCU)、运算放大器(OPAMP)等IC电源引脚旁路,抑制电源噪声;
  4. 工业控制电路:PLC输入输出模块、传感器信号调理电路,适应宽温环境;
  5. 消费电子:电视、机顶盒、智能家居设备的电源与信号处理模块。

五、可靠性与质量认证

三环电子对该产品进行了严格可靠性测试,核心指标如下:

  • 焊接热冲击:260℃回流焊3次,容值变化≤±5%,无开裂;
  • 温度循环:-55℃~+125℃循环1000次,容值变化≤±10%;
  • 湿度测试:85℃/85%RH环境下1000h,容值变化≤±10%,绝缘电阻≥10^9Ω;
  • 质量认证:通过ISO9001质量管理体系认证,部分批次符合ISO/TS16949汽车级标准(需确认具体批次)。

六、选型与使用注意事项

  1. 电压降额:严格遵循80%直流降额(≤40V),交流降额70%(≤35V),避免过压损坏;
  2. 贴装工艺:回流焊温度曲线需满足:预热150180℃(60120s)、回流峰值240260℃(1030s)、冷却速率≤6℃/s;
  3. 存储条件:未开封产品存储于常温干燥环境(湿度≤60%),保质期2年;开封后1个月内使用完毕,避免吸潮;
  4. 静电防护:MLCC为静电敏感元件(ESD等级≤2kV),操作时需佩戴防静电手环,使用接地工作台。

该产品以高性价比、稳定性能成为通用电路的优选MLCC,可满足多数中低压电子设备的设计需求。

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
