TCC0402X5R334K160AT 贴片陶瓷电容(MLCC)产品概述

TCC0402X5R334K160AT是三环电子(CCTC) 推出的0402封装通用型多层陶瓷电容(MLCC),专为低电压、小型化电子设备设计,平衡了容值稳定性、封装密度与成本优势,是便携电子、消费电子等领域的常用基础元件。

一、核心身份与定位

该产品属于中温稳定型MLCC,针对需要在宽温度范围保持容值稳定,同时追求小型化的应用场景:

  • 品牌:三环电子(CCTC),国内MLCC主流厂商,产品覆盖消费、工业、汽车等领域;
  • 封装:0402(英制)/1005(公制,1.0mm×0.5mm),满足高密度PCB设计需求;
  • 定位:低电压(≤16V)通用电容,替代传统体积更大的电容,适配便携设备紧凑空间。

二、关键参数详细解读

2.1 容值与精度

  • 标称容值:330nF(对应电容标识“334”,即33×10⁴ pF=330nF);
  • 精度:±10%(标识“K”),满足大多数通用电路的滤波、耦合需求,无需高精度场合的额外成本。

2.2 额定电压与使用限制

  • 额定电压:16V DC,适用于电池供电(如3.7V锂电池、5V USB)等低电压电路;
  • 注意:实际工作电压建议不超过额定电压的80%(≤12.8V),避免长期过压导致容值漂移或失效。

2.3 温度系数(X5R)

X5R是MLCC常见的中温稳定介质,符合EIA标准:

  • 工作温度范围:-55℃ ~ +85℃;
  • 容值变化:±15%(相对于25℃基准值);
  • 对比优势:比Y5V(-30℃~+85℃,±20%)温度范围更广,比C0G(高精度)成本低30%以上,性价比突出。

2.4 封装尺寸

0402封装(公制1005)尺寸为1.0mm×0.5mm×0.5mm(典型值),相比0603封装体积缩小约60%,可在相同PCB面积内布局更多电容,提升电路密度。

三、制造工艺与可靠性特点

3.1 叠层陶瓷工艺

采用多层陶瓷介质叠层+镍基内电极结构,通过精密印刷、叠压、烧结工艺实现:

  • 容值一致性好:批量生产容值偏差控制在±10%以内;
  • 抗机械应力:叠层结构分散应力,减少焊接或振动导致的开裂风险。

3.2 端电极设计

端电极采用三层结构(镍/铜/纯锡),符合RoHS无铅标准:

  • 焊接兼容性:适配回流焊、波峰焊工艺,焊点附着力强(拉力测试≥2N);
  • 耐腐蚀性:纯锡镀层避免铅污染,长期使用不易氧化。

3.3 可靠性认证

  • 符合ISO9001质量管理体系、IATF16949汽车级认证(可选);
  • 经过高温存储(125℃×1000h)、温度循环(-55℃~+85℃×1000次)、湿度循环(85℃/85%RH×500h)等测试,容值漂移≤5%。

四、典型应用场景

该产品因小型化、中温稳定的特点,广泛用于以下领域:

  1. 便携电子设备:智能手机主板电源去耦、蓝牙耳机信号耦合、智能手环传感器滤波;
  2. 小型消费电子:无线充电盒、智能音箱、便携式充电宝的内部电路;
  3. 低电压工业控制:小型PLC输入输出模块、物联网传感器节点的电源滤波;
  4. 通信模块:Wi-Fi 6模块、蓝牙5.0模块的射频去耦电容。

五、产品优势总结

TCC0402X5R334K160AT的核心优势在于:

  • 小型化:0402封装适配高密度PCB,满足便携设备轻薄化需求;
  • 稳定性:X5R介质在-55℃~+85℃内容值波动小,适合户外或宽温环境;
  • 性价比:比C0G成本低,比Y5V稳定,平衡性能与成本;
  • 可靠性:三环品牌认证,批量一致性好,适合量产应用。

该产品是低电压、小型化电子设备的理想基础元件,可有效替代传统电容,提升电路设计灵活性与空间利用率。

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
