TCC0805X7R152K251DT 贴片多层陶瓷电容(MLCC)产品概述

一、产品基本属性与型号解析

TCC0805X7R152K251DT是三环电子(CCTC) 推出的一款通用型表面贴装多层陶瓷电容(MLCC),专为中高压、宽温环境下的电子电路设计。其型号可直观解析核心参数:

  • TCC:三环电子品牌专属代码;
  • 0805:英制封装尺寸(0.08英寸×0.05英寸,对应公制2.0mm×1.25mm);
  • X7R:温度系数标识(-55℃~+125℃工作范围,容值变化±15%);
  • 152:容值代码(15×10² pF = 1.5nF);
  • K:容值精度(±10%);
  • 251:额定电压(25×10¹ V = 250V DC);
  • DT:生产工艺或批次辅助标识(不影响核心性能)。

二、核心性能参数详解

1. 容值与精度

标称容值为1.5nF(1500pF),精度±10%,无需额外校准即可适配常规滤波、耦合场景,满足90%以上通用电路的偏差要求。

2. 额定电压与降额要求

额定电压为250V直流(DC),交流(AC)应用需按1.414倍降额(最大交流电压≤177V),可覆盖中高压小功率电路(如开关电源输出端、工业控制电源滤波)。

3. 温度特性(X7R系数)

X7R是陶瓷电容中平衡容值稳定性与容值密度的典型方案:

  • 工作温度范围:-55℃~+125℃(适配车载、户外设备等宽温场景);
  • 容值变化:全温区内容值偏差≤±15%,远优于Y5V(±20%~-82%),且容值密度高于NPO(零温度系数但容值偏小),适合兼顾稳定性与空间的设计。

4. 损耗与ESR

MLCC本身损耗极低,该型号在1kHz测试频率下,损耗角正切值(tanδ)典型值≤2%,等效串联电阻(ESR)≤100mΩ,可有效降低电路功率损耗,提升滤波效率。

三、封装与工艺特性

采用0805表面贴装封装,具备以下优势:

  • 尺寸小巧:公制2.0mm×1.25mm×1.0mm(典型厚度),适配高密度PCB设计(如消费电子主板、工业控制板);
  • 可焊性优异:电极采用银钯合金(Ag-Pd),兼容回流焊、波峰焊工艺,焊接后焊点可靠性高;
  • 无引线设计:减少寄生电感,适合10MHz以下高频信号耦合(如音频、射频低端电路)。

四、典型应用场景

该电容因平衡性能与成本,广泛应用于:

  1. 电源电路:开关电源输出滤波、线性电源去耦、电压调节器辅助滤波;
  2. 工业控制:PLC输入输出电路、变频器控制板滤波、传感器信号调理;
  3. 消费电子:电视、机顶盒、智能家居设备的电源与音频信号耦合;
  4. 车载电子:车载中控、行车记录仪的宽温环境电路(适配-40℃~+85℃车载温度)。

五、可靠性与环境适应性

三环电子对该型号进行了严格可靠性测试,符合国际标准:

  • 温度循环:-55℃~+125℃循环1000次,容值变化≤±5%;
  • 耐湿性:通过IEC 60068-2-66湿热测试,存储与工作中不易受潮;
  • 振动与冲击:满足MIL-STD-202振动(10g~2000Hz)与冲击(100g/11ms)要求,适合无人机、手持终端等运动设备;
  • 寿命:额定条件下MTBF(平均无故障时间)≥10^6小时,商用级产品可靠性稳定。

六、品牌与品质保障

CCTC(三环电子)是国内MLCC领域主流供应商,产品具备:

  • 质量管理体系:ISO 9001、IATF 16949(车载级认证);
  • 环保认证:RoHS 2.0、REACH(无铅、无有害物质);
  • 供货保障:批量生产能力稳定,可追溯性强,适合OEM/ODM客户批量采购。

该型号是中高压通用MLCC的高性价比选择,可满足多数工业、消费电子场景的核心需求。

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
