TCC0805X7R684K500DT 贴片多层陶瓷电容(MLCC)产品概述

一、产品核心定位与基本属性

TCC0805X7R684K500DT是三环电子(CCTC) 推出的通用型贴片多层陶瓷电容(MLCC),专为低压直流/交流电路的滤波、耦合、旁路及储能场景设计。该产品采用0805(英制)/2012(公制)小型化贴片封装,兼顾高容量密度与宽温稳定性,适配消费电子、工业控制、通信等多领域的标准化电路需求,是替代传统铝电解电容、提升电路集成度的优选器件。

二、关键参数详解

(1)容值与精度

容值标称680nF(编码“684”,即68×10⁴pF),精度等级为**±10%(K档)**,满足民用及工业级电路对容值偏差的常规要求,无需额外复杂的匹配设计即可稳定工作。

(2)额定电压

直流额定电压为50V,覆盖绝大多数低压电子设备的电源轨(如12V、24V、48V系统);交流应用需遵循“交流峰值电压≤直流额定电压”的降额原则,确保长期可靠性。

(3)温度系数

介质材料采用X7R 温度特性,符合EIA标准:工作温度范围为**-55℃至+125℃**,在此区间内容值变化不超过±15%,相比Y5V等低成本介质,稳定性显著提升。

(4)封装尺寸

封装为0805(英制:0.08英寸×0.05英寸;公制:2.0mm×1.25mm),厚度约1.0mm(典型值),适配常规自动化贴片机作业精度,可直接集成于高密度PCB设计中。

三、封装与工艺特点

(1)小型化封装优势

0805封装是MLCC主流规格之一,体积小、重量轻,可有效降低整机尺寸与重量,尤其适合智能手机、可穿戴设备、小型通信模块等对空间敏感的产品。

(2)叠层工艺与介质特性

采用多层陶瓷叠层工艺,将高介电常数的X7R介质层(εr≈2000-3000)与镍基内电极交替叠压,经高温烧结成型——既保证680nF的大容量密度,又避免单层电容的体积劣势;X7R介质的高介电常数是实现大容量的核心,同时兼顾温度稳定性。

(3)端电极可靠性设计

外端电极采用三层结构(镍层+锡层+抗氧化层),焊接性符合IPC J-STD-002标准,适配回流焊、波峰焊等常规贴片工艺,且抗氧化性能优异,长期使用无脱焊、虚焊风险。

四、温度特性与稳定性

X7R介质的温度特性是该产品核心优势:

  • 低温区(-55℃):容值变化≤+15%;
  • 常温区(25℃):容值稳定在标称值±10%内;
  • 高温区(125℃):容值变化≤-15%;
    相比Y5V(容值变化可达+22%/-82%),X7R的容值波动小,可确保电路在宽温环境下的滤波、耦合效果一致,避免温度变化导致的信号失真或电源纹波增大。

五、典型应用场景

该产品因参数均衡,适配多领域场景:

  1. 消费电子:智能手机、平板电脑的电源滤波(如BMS的EMI滤波)、音频耦合;
  2. 工业控制:PLC的信号隔离耦合、传感器接口滤波;
  3. 通信设备:路由器、交换机的高频旁路电容、电源模块滤波;
  4. 医疗设备:小型监护仪的电源滤波(低干扰需求);
  5. 汽车电子:车载中控、仪表盘的低压电路滤波(商用级场景)。

六、品牌与可靠性保障

三环电子(CCTC)是国内MLCC主流供应商,产品符合RoHS 2.0、REACH 环保标准,无铅无卤;该产品经过多项可靠性测试:

  • 高温老化(125℃×1000h):容值变化≤±5%;
  • 温度循环(-55℃~125℃×500次):无开路、短路;
  • 湿度试验(85℃/85%RH×1000h):绝缘电阻≥10⁹Ω;
    长期供货稳定,可满足批量生产的一致性需求。

该产品以高性价比、宽温稳定及小型化优势,成为低压电路设计中替代传统电容的实用选择,适配多行业的标准化应用需求。

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
