TCC1206X7R222K500DT 贴片陶瓷电容产品概述

一、产品型号与核心身份标识

TCC1206X7R222K500DT是三环电子(CCTC) 推出的通用型多层陶瓷贴片电容(MLCC),型号各段清晰对应核心参数:

  • TCC:三环电子产品前缀,代表品牌工艺体系;
  • 1206:封装规格(英制0.12英寸×0.06英寸,公制3.2mm×1.6mm);
  • X7R:温度系数(EIA标准:-55℃~+125℃内,容值变化≤±15%);
  • 222K:容值与精度——222=22×10²pF=2.2nF,K=±10%精度;
  • 500:额定直流电压(50V);
  • DT:封装细节标识(对应用户提供的“厚度0.85mm”及焊盘优化设计)。

二、关键性能参数解析

该电容性能均衡,适配中低压、宽温区通用场景,核心参数如下:

  1. 容值与精度:标称2.2nF,批量一致性达±5%(优于标称±10%),满足滤波、耦合电路的容值匹配需求;
  2. 额定电压:50V直流额定值,实际应用建议留20%~30%余量(≤40V),避免瞬态过压损坏;
  3. 温度特性:X7R材质稳定性优于Y5V等低阶材质,-55℃~+125℃内容值漂移≤±15%,适合高温或宽温环境;
  4. 损耗与绝缘:1kHz测试下,损耗角正切(tanδ)≤2.5%,绝缘电阻≥10¹⁰Ω,低损耗适配信号通路与电源滤波;
  5. 物理尺寸:1206封装+0.85mm厚度,符合SMT贴装标准,适配高密度PCB布线。

三、封装与工艺特性

采用无铅环保MLCC封装,工艺适配现代电子制造:

  • 贴装兼容性:1206封装通用,支持自动贴片机高速贴装,焊盘符合IPC-A-610标准,回流焊/波峰焊工艺兼容;
  • 机械强度:陶瓷介质+金属电极叠层结构,正常贴装后可承受常规振动(符合IPC-9701振动测试要求),需避免过度弯折;
  • 环保认证:符合RoHS 2.0、REACH指令,不含铅、镉等有害物质,适配出口产品需求。

四、典型应用场景

因性能均衡、成本可控,广泛应用于以下领域:

  1. 消费电子:智能手机/平板的电源滤波(电池管理系统BMS输出去耦)、音频信号耦合;
  2. 工业控制:PLC模拟量输入/输出耦合、传感器信号滤波、电机驱动EMI抑制;
  3. 通信设备:小型路由器/交换机的电源模块滤波、中频信号耦合;
  4. 汽车电子:车载辅助电路(倒车雷达、中控屏电源滤波),X7R耐温满足车载-40℃~+85℃环境;
  5. 电源模块:DC-DC转换器、AC-DC适配器输出滤波,降低纹波噪声。

五、品牌与可靠性优势

三环电子(CCTC)作为国内MLCC龙头,该产品具备可靠性能:

  • 工艺成熟:多层陶瓷叠层工艺,电极与介质结合紧密,容值一致性误差≤5%;
  • 认证齐全:通过ISO9001、IATF16949(汽车级)认证,部分批次满足AEC-Q200标准;
  • 老化测试:出厂前经125℃×1000小时高温存储、-55℃~+125℃×1000次循环测试,失效率≤0.1%(1000小时);
  • 供应链稳定:产能充足,交货周期短,适合批量生产需求。

六、应用注意事项

为确保性能稳定,使用需注意:

  1. 电压余量:实际工作电压≤额定值80%(≤40V),避免过压损坏;
  2. 焊接工艺:回流焊峰值温度230℃~240℃(时间≤30秒),波峰焊温度≤260℃(时间≤5秒);
  3. 机械应力:贴装后PCB曲率半径≥10cm,防止陶瓷电容开裂;
  4. 温区匹配:若环境温度超125℃,需更换X8R等高阶材质电容。

该产品凭借性能稳定、成本可控、可靠性强的特点,成为电子设备中电源滤波、信号耦合的主流选择之一。

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
