TCC0603X7R181K500CT 贴片多层陶瓷电容(MLCC)产品概述

一、产品核心身份与命名逻辑

TCC0603X7R181K500CT是三环电子(CCTC) 推出的一款贴片多层陶瓷电容(MLCC),型号命名严格遵循电子元器件行业标准,各段代码对应明确:

  • TCC:三环电子品牌专属前缀;
  • 0603:英制封装代码,对应公制尺寸1.6mm×0.8mm(长×宽),是小型化电子设备的主流贴片封装;
  • X7R:温度系数标识,代表工作温度范围-55℃~+125℃,容值变化控制在±15%以内;
  • 181:容值代码(行业通用规则:前两位为有效数字,第三位为10的幂次),即18×10¹=180pF;
  • K:精度等级,±10%;
  • 500:额定电压,50V(直流/交流峰值);
  • CT:三环内部封装/批次标识,保障产品一致性。

二、关键性能参数详解

该产品的核心参数覆盖低中压电路的主流需求,具体如下:

  1. 容值与精度:标称容值180pF,精度±10%,满足大多数信号匹配、滤波场景的误差要求(如射频电路的阻抗匹配、电源的高频去耦);
  2. 额定电压:50V额定电压,适用于直流12V/24V、交流峰值≤50V的电路(如消费电子电源、工业控制模块),避免过压风险;
  3. 温度特性:X7R介质的宽温稳定性是核心优势——在-55℃~+125℃范围内,容值波动≤±15%,优于Y5V等低阶介质,适合环境温度波动较大的应用(如车载、户外设备);
  4. 损耗与绝缘:典型损耗角正切(DF)<1%@1kHz,绝缘电阻>10⁹Ω,信号传输损耗低,抗漏电性能好,适合射频、高速信号线路。

三、封装与物理特性

采用0603贴片封装,是目前小型化电子设备的主流选择:

  • 物理尺寸:1.6mm(长)×0.8mm(宽)×0.8mm(厚,典型值),体积仅约1.02mm³,可显著节省PCB空间(比同容值电解电容体积小80%以上);
  • 结构特点:多层陶瓷介质叠层+银/镍电极印刷,容值密度高,无极性,焊接兼容性强;
  • 焊接工艺:支持回流焊(峰值温度≤235℃)、波峰焊(需适配夹具),符合SMT自动化生产要求,适合大规模量产。

四、典型应用场景

该产品的参数特性使其适用于多个领域的低中压电路:

  1. 消费电子:手机、平板的射频(RF)电路匹配(天线、滤波器),电源模块滤波(LDO输出、DC-DC输入);
  2. 工业控制:PLC模块、传感器节点的信号耦合、去耦,小型电机驱动电路的EMI滤波;
  3. 汽车电子:车载音响、胎压监测、辅助驾驶传感器的低中压电路(符合汽车级温度范围);
  4. 通信设备:路由器、交换机的高速信号线路匹配,电源滤波网络(如POE供电模块)。

五、品牌与可靠性优势

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

  • 认证保障:通过ISO9001质量管理体系、AEC-Q200(汽车级)认证(部分批次),满足工业、汽车领域的可靠性要求;
  • 一致性:生产过程采用自动化叠层、印刷工艺,批次间容值、温度特性偏差≤1%,适合量产应用;
  • 抗老化:X7R介质化学稳定性好,长期使用后容值变化<1%/1000小时,寿命符合行业标准(≥10万小时)。

六、选型与使用注意事项

为保障产品性能与可靠性,使用时需注意以下几点:

  1. 电压匹配:工作电压(直流/交流峰值)不得超过50V,避免介质击穿;
  2. 温度范围:使用环境温度需控制在-55℃~+125℃内,超出范围会导致容值波动或性能下降;
  3. 焊接工艺:回流焊峰值温度不超过235℃,避免机械应力(如PCB弯曲)导致电容开裂;
  4. 容值适配:若需更高精度(±5%),可选择同系列J档产品;若需更大容值,可切换0805封装的X7R系列。

该产品凭借小型化、宽温稳定、高可靠性等特点,成为消费电子、工业控制等领域的高性价比选择。

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
