TCC0402X7R331K500AT 贴片多层陶瓷电容(MLCC)产品概述

TCC0402X7R331K500AT是三环电子(CCTC) 推出的一款小型化贴片多层陶瓷电容(MLCC),针对电子设备的高密度贴装与宽温稳定需求设计,兼具中等容值、中低压耐受能力,适用于多类消费电子、物联网及工业控制场景。

一、产品型号解析与基本属性

该型号命名遵循行业通用规则,各部分含义清晰可辨:

  • TCC:三环电子MLCC核心产品系列标识;
  • 0402:封装尺寸(英制),对应公制尺寸为1.0mm×0.5mm(长×宽),适配主流小型化贴装工艺;
  • X7R:温度系数类别,代表工作温度范围**-55℃~+125℃**,容值变化≤±15%;
  • 331:容值编码,即33×10¹=330pF(皮法);
  • K:容值精度等级,对应**±10%**;
  • 500:额定直流电压,即50V;
  • AT:产品后缀,代表常规无极性MLCC,无特殊封装或功能扩展。

二、核心电气性能参数

TCC0402X7R331K500AT的电气性能满足中低压电路的滤波、耦合及旁路需求,关键参数如下:

  1. 容值与精度:标称330pF,精度±10%,覆盖常规电路对中等容值的核心需求;
  2. 额定电压:直流50V,适配3.3V/5V/12V系统的辅助滤波,留有安全余量;
  3. 损耗特性:1kHz频率下,损耗角正切(tanδ)典型值≤2.5%,减少电路功率损耗;
  4. 绝缘电阻:25℃环境下,50V直流测试时≥10¹⁰Ω,保证电路绝缘可靠性;
  5. 频率特性:100kHz~10MHz范围内容值稳定,适合高频滤波应用。

三、封装与物理特性

0402封装是该产品的核心优势,适配高密度PCB设计:

  • 尺寸参数:长1.0±0.2mm,宽0.5±0.2mm,厚度(典型值)0.5mm,满足小型化设备的空间限制;
  • 端电极结构:镍(Ni)+锡(Sn)镀层,兼容回流焊、波峰焊等贴装工艺,焊接可靠性高;
  • 介质与电极:X7R型钛酸钡基陶瓷介质,多层镍电极堆叠,实现高容值与小型化的平衡;
  • 环保合规:符合RoHS 2.0、REACH标准,无铅无卤,适配出口及绿色制造需求。

四、X7R温度特性的应用价值

X7R是MLCC中应用最广泛的温度系数之一,相比其他类别优势明显:

  • 温度稳定性:-55℃+125℃宽温范围内,容值变化≤±15%,优于Y5V(±20%-82%)等高容值温系;
  • 容值覆盖:支持10pF~10μF区间,330pF属于中等容值,适配滤波、耦合等核心功能;
  • 成本平衡:相比NPO(高精度、低容值),X7R在容值与成本间实现最优平衡,适合量产。

五、典型应用场景

TCC0402X7R331K500AT的小型化、稳定性能适配多类设备:

  1. 消费电子:智能手机射频滤波、智能手表电源旁路、音频电路耦合;
  2. 物联网设备:温湿度传感器节点信号滤波、运动传感器数据传输稳定;
  3. 工业控制:小型PLC辅助滤波、电机驱动模块旁路,适配工业宽温环境;
  4. 汽车电子:车载超声波传感器电路、12V/24V系统辅助滤波。

六、品牌与可靠性保障

三环电子作为国内MLCC龙头,该产品可靠性经过严格验证:

  • 可靠性测试:通过回流焊(峰值260℃)、高低温存储(-55℃+125℃)、湿度老化(85℃/85%RH)测试,满足510年使用寿命;
  • 量产稳定性:自动化生产工艺,容值一致性好,适配大规模SMT贴装,减少不良率;
  • 技术支持:提供选型指导、焊接工艺建议,帮助客户优化电路设计。

综上,TCC0402X7R331K500AT是一款性价比突出的小型化MLCC,兼具稳定性能、宽温适应性与环保合规性,是消费电子、物联网及工业控制领域的理想选择。

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
