TCC0204X7R154K250AT 贴片多层陶瓷电容(MLCC)产品概述

一、核心参数与型号解读

TCC0204X7R154K250AT是三环电子(CCTC)推出的常规商用级MLCC,核心参数清晰明确:

  • 容值:150nF(型号中“154”为标识,即15×10⁴pF);
  • 精度:±10%(标识“K”,满足多数常规电路需求);
  • 额定电压:25V(标识“250”,为安全工作电压上限);
  • 介质材料:X7R(陶瓷介质类型);
  • 封装:0402(英制尺寸,对应公制1.0mm×0.5mm×0.5mm);
  • 品牌:CCTC(三环电子,国内MLCC老牌厂商)。

型号拆解逻辑:TCC(三环品牌代码)+ 0402(封装尺寸)+ X7R(介质)+ 154(容值)+ K(精度)+ 250(额定电压)+ AT(商用级系列后缀)。

二、X7R介质的性能适配性

X7R是MLCC中平衡温度稳定性与容值密度的经典介质,核心特性直接决定产品适用场景:

  1. 温度范围:-55℃ ~ +125℃(覆盖多数消费电子、工业设备的工作温度);
  2. 容值稳定性:温度变化范围内容值偏差≤±15%(远优于Y5V等低价介质,满足信号耦合、滤波的基本精度需求);
  3. 容值密度:相同0402封装下,比COG(NPO)介质可实现更高容值(150nF为常规量产规格);
  4. 成本优势:相比高温介质(如X8R),性价比更高,适合商用级电路。

三、0402封装的尺寸与应用价值

0402是小尺寸贴装规格,尺寸仅1.0mm(长)×0.5mm(宽),核心价值在于支持高密度布局:

  • 便携设备适配:智能手机、智能手表等小型化设备的主板可通过该封装减少PCB占用面积(单颗电容仅占0.5mm²左右);
  • 轻量化设计:单颗重量约0.005g,对可穿戴设备的重量控制无压力;
  • 贴装兼容性:适配多数常规贴片机(如ASM、YAMAHA),支持批量自动化生产,良率稳定(行业平均良率≥99.5%)。

四、额定电压与可靠性设计

额定电压25V是产品安全工作的关键参数,实际使用需注意2点:

  1. 电压降额:建议工作电压不超过20V(额定值的80%),避免电应力导致的介质老化加速(长期超压可能引发短路);
  2. 可靠性标准:三环产品符合IEC 60384-14(MLCC通用标准),批量产品通过“高温负载测试”“湿度循环测试”,商用场景下平均寿命≥10万小时。

五、典型应用场景

该电容因参数适配性强,广泛覆盖以下领域:

  1. 消费电子:智能手机主板的CPU供电滤波、蓝牙/WiFi模块的射频耦合电容;
  2. 可穿戴设备:智能手表的传感器信号耦合、低功耗电路的旁路电容;
  3. 小型工业设备:PLC扩展模块的电源滤波、温度传感器节点的信号滤波;
  4. 车载辅助电路:车载小屏的电源电路(需注意:常规AT系列为商用,车规需求需选三环车规级系列)。

六、选型与使用注意事项

  1. 温度匹配:若应用环境温度超过125℃(如工业高温炉附近),需更换X8R介质产品;
  2. 焊接工艺:0402封装需控制回流焊温度(峰值230~245℃,时间≤30s),避免热应力导致电容开裂;
  3. 存储条件:未开封产品存储于2030℃、湿度40%60%环境,开封后建议1个月内用完(受潮会导致焊接虚焊);
  4. 精度升级:若需±5%精度,可选择同系列标识“J”的产品(如TCC0204X7R154J250AT)。

七、品牌与质量优势

三环电子(CCTC)是国内MLCC领域的老牌厂商(成立于1970年),产品优势明确:

  • 自主技术:拥有陶瓷粉体制备核心技术,容值一致性优于行业平均;
  • 环保合规:全系列符合RoHS 2.0、REACH、无卤素标准;
  • 供应链稳定:国内产能充足,交货周期(常规订单)≤7天,适合量产需求;
  • 技术支持:提供选型手册、应用案例及现场焊接指导,降低客户试产成本。

该产品凭借“小尺寸、稳定性能、高性价比”,成为消费电子、可穿戴设备等领域的常规选型之一,满足多数商用电路的滤波、耦合、旁路需求。

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
