一、产品核心身份与封装规格

CGA2B3X7S1A474KT000N是TDK推出的通用型贴片多层陶瓷电容(MLCC),采用行业标准0402封装(英制标识,对应公制1005尺寸:长1.0±0.2mm、宽0.5±0.2mm、厚度0.5±0.1mm),适配高密度PCB设计,可显著节省电路板空间,满足小型化电子设备的集成需求。

产品端电极采用镍(Ni)底层+锡(Sn)表层无铅镀层结构,兼容回流焊、波峰焊等主流贴片工艺,焊接附着力强、可靠性高,且符合全球环保法规对无铅化的要求。

二、关键电气性能参数详解

该型号针对低电压、小容值场景优化,核心参数精准可靠:

  1. 容值与精度:标称容值470nF(EIA代码474,即47×10⁴pF),精度等级±10%(EIA代码K),满足大多数通用电路的容值偏差需求;
  2. 额定电压:额定工作电压10V(EIA代码A),可在10V直流电压下长期稳定运行,适配低功耗、低电压电路;
  3. 损耗特性:1kHz、25℃环境下,损耗角正切(tanδ)≤2.5%,能量损耗低,适合信号耦合、电源滤波等对损耗敏感的场景;
  4. 绝缘性能:25℃、额定电压下,绝缘电阻(IR)≥10¹⁰Ω,漏电流极小,可有效避免对电路的干扰。

三、温度特性与可靠性表现

产品采用X7S温度系数陶瓷介质,具备出色的宽温稳定性:

  1. 温度范围:工作温度覆盖-55℃至+125℃,满足户外IoT、车载低功耗模块等宽温环境需求;
  2. 容值温度变化:全工作温度范围内,容值变化≤±15%,温度稳定性优于普通陶瓷电容,确保电路性能在温度波动下保持一致;
  3. 可靠性验证:通过TDK严格测试,包括:
    • 高温负载寿命(HTOL):+125℃、额定电压下1000小时测试,容值变化≤±10%,绝缘电阻≥初始值50%;
    • 湿度负载寿命(HALT):85℃/85%RH、额定电压下1000小时测试,性能无明显衰减;
    • 机械可靠性:通过振动(10~2000Hz,1.5g加速度)、冲击(1500g峰值,0.5ms持续)测试,适配移动设备振动环境。

四、典型应用场景

凭借小封装、宽温特性与稳定性能,该型号广泛应用于:

  1. 便携式消费电子:智能手机、智能手表、蓝牙耳机的电源旁路、信号耦合电容;
  2. 物联网(IoT)设备:低功耗传感器节点、智能家居终端的滤波与去耦;
  3. 通信模块:蓝牙、Wi-Fi、LoRa等无线模块的射频滤波,降低信号干扰;
  4. 工业控制:小型PLC、传感器接口的去耦电容,确保信号传输稳定;
  5. 车载低功耗组件:车载信息娱乐系统的辅助电路(如按键背光、低功耗传感器)。

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
