TCC0402X7R511K500AT 贴片多层陶瓷电容(MLCC)产品概述

一、产品基本信息

TCC0402X7R511K500AT是三环电子(CCTC) 推出的通用型贴片多层陶瓷电容(MLCC),型号各段含义明确:

  • TCC:三环电子品牌标识;
  • 0402:英制封装尺寸(对应公制1005,长1.0mm×宽0.5mm);
  • X7R:温度系数代码;
  • 511:容值标识(前两位有效数字51,第三位幂次1,即51×10¹=510pF);
  • K:容值精度(±10%);
  • 500:额定电压(50V);
  • AT:卷盘包装后缀(常见于贴片元件批量供应)。

该产品定位于通用电子电路的滤波、耦合、旁路等基础功能,适配高密度PCB设计需求。

二、核心性能参数详解

2.1 容值与精度

容值510pF(±10%)属于电子电路常用小容量范围,精度满足大多数非高精度场景(如电源滤波、信号耦合),无需特殊校准即可稳定工作。

2.2 额定电压

50V额定电压高于常见低压电路(5V/12V/24V)的工作电压,留有充足安全裕量,可避免电压波动导致的击穿风险,适合中等电压环境的稳定运行。

2.3 温度系数X7R

X7R是MLCC中温度稳定型材料,核心参数:

  • 工作温度范围:-55℃~+125℃;
  • 温度范围内容值变化:±15%以内;
  • 介电常数适中,兼具温度稳定性与容量密度,优于Y5V等低成本材料的温漂特性。

2.4 封装尺寸

0402封装(1005公制)体积小巧,可有效节省PCB空间,适配智能手机、智能穿戴等小型化设备的高密度布局。

三、产品主要特点

  1. 宽温稳定性能:X7R材料确保-55℃至+125℃范围内容值波动小,适合车载、工业控制等环境温度变化大的场景;
  2. 高可靠性设计:三环成熟的MLCC生产工艺,产品通过高温老化、湿度循环等测试,寿命长、故障率低;
  3. 小型化适配:0402封装支持紧凑PCB布局,满足便携设备的空间限制;
  4. 电压裕量充足:50V额定电压覆盖12V/24V等常见低压电路,避免过压损坏;
  5. 环保合规:符合RoHS、REACH标准,无铅无卤,适配全球市场需求。

四、典型应用场景

  1. 便携电子:智能手机射频信号耦合、智能手表电源滤波、蓝牙耳机噪声抑制;
  2. 小型家电:智能插座稳压、加湿器控制模块滤波、小型遥控器信号耦合;
  3. 工业控制:小型PLC传感器信号调理、工业传感器电源滤波(宽温需求);
  4. 车载电子:车载充电器辅助稳压、行车记录仪信号旁路(适配车载宽温);
  5. 通信设备:小型路由器WiFi模块射频耦合、IoT终端电源滤波。

五、选型与使用注意事项

  1. 容值匹配:适用于滤波、耦合等对精度要求不高的场景,若需高精度(如谐振电路)需换NPO材料;
  2. 电压限制:电路工作电压需低于50V,避免过压击穿;
  3. 温度适配:若环境温度超出-55℃~+125℃,需更换X5R(-40℃~+85℃)或NPO(更高精度);
  4. 焊接工艺:0402封装焊接温度建议230℃~260℃,时间≤3秒,避免虚焊/过热;
  5. 存储条件:未使用产品存放在湿度<60%的干燥环境,避免受潮影响性能。

六、品牌与可靠性说明

三环电子(CCTC)是国内老牌MLCC制造商,拥有30余年生产经验,产品线覆盖全系列封装。TCC0402X7R511K500AT通过ISO9001认证,且经过高温寿命测试(125℃下1000小时容值变化<±5%),确保场景稳定性。

TCC0402X7R511K500AT凭借稳定性能、小型化设计与高可靠性,成为通用电子电路的优选MLCC元件,广泛适配各类便携、小型化设备需求。

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
