0402B333K160CT 多层陶瓷电容器产品概述

一、产品基本信息

0402B333K160CT是华新科(Walsin)推出的多层陶瓷电容器(MLCC),型号命名直接对应核心参数:

  • 前缀“0402”:英制封装尺寸(长0.04英寸×宽0.02英寸),公制标识为1005(1.0mm×0.5mm);
  • “B”:产品系列标识(华新科X7R介质MLCC专用系列);
  • “333”:容值编码(33×10³ pF=33nF);
  • “K”:容值精度(±10%);
  • “160”:额定直流电压(16V);
  • 后缀“CT”:温度特性与封装细节补充(匹配X7R介质的宽温要求)。

该产品属于低中压小封装MLCC,兼顾容值密度与温度稳定性,是电子设备中电源滤波、信号耦合的常用元件。

二、核心技术参数详解

参数项 规格值 备注 标称容值 33nF(333pF) 1000pF=1nF,编码规则33×10³pF 容值精度 ±10%(K档) 符合EIA标准电容精度等级 额定直流电压(VDC) 16V 适用于≤16V直流的低中压电路 温度系数 X7R 温度范围-55℃~+125℃,容变±15% 封装尺寸 0402(英制)/1005(公制) 长1.0mm×宽0.5mm×厚~0.5mm(典型) 介质类型 多层陶瓷 无极性设计,表面贴装(SMT) 环保认证 RoHS、REACH 无铅无卤,符合欧盟环保要求

关键参数中,X7R温度系数是核心优势:相比Y5V(温变±20%)更稳定,相比NPO(COG,温变±0.05%)容值密度更高,适配多数实用场景。

三、封装与贴装特性

0402封装是电子设备高密度贴装的主流小封装,具有以下特点:

  1. 尺寸紧凑:1.0mm×0.5mm的占地面积仅0.5mm²,可大幅提升PCB布局密度,适配智能手机、智能穿戴等小型化设备;
  2. 贴装兼容性:焊盘设计符合IPC标准,兼容富士、西门子等主流SMT贴片机,焊接良率≥99.5%;
  3. 耐热性:支持无铅回流焊(峰值温度260℃,持续时间≤30秒),兼容波峰焊(需专用夹具);
  4. 机械强度:陶瓷介质与电极层的层压结构,可承受常规振动(10~2000Hz,加速度≤1.5g)与跌落冲击(符合IEC 60068-2-32标准)。

四、X7R介质材料的应用优势

X7R是MLCC中高性价比的介质材料,0402B333K160CT采用该材料的核心优势:

  • 宽温范围稳定:在-55℃~+125℃的工业级温度范围内,容值变化≤±15%,满足户外设备、车载低功耗模块等宽温需求;
  • 容值密度高:相同封装下,X7R的容值是NPO的5~10倍,33nF在0402封装中属于中等偏上容值,适配电源滤波的高频需求;
  • 损耗适中:介电损耗角正切(tanδ)≤0.01(1kHz下),适合信号耦合、去耦等应用,不会引入明显信号衰减;
  • 成本可控:相比NPO材料,X7R制造成本更低,适合大规模量产的消费电子、工业设备。

五、典型应用场景

0402B333K160CT因小封装、宽温稳定、16V电压适配性,广泛应用于以下领域:

  1. 消费电子:智能手机/平板的电源管理单元(PMU)滤波、音频电路耦合、射频前端辅助去耦;
  2. 工业控制:小型PLC、温度/压力传感器模块的电源去耦、信号滤波;
  3. 车载电子(低功耗):车载小屏显示、胎压监测模块(TPMS)、辅助控制单元(ACU)的电源稳压;
  4. 通信设备:小型路由器、Wi-Fi/蓝牙模块的电源滤波、信号耦合;
  5. 物联网设备:低功耗MCU(如STM32L系列)周边电路、传感器节点的去耦电容。

六、品牌与可靠性保障

华新科(Walsin)是全球前五大MLCC制造商之一,0402B333K160CT通过严格测试与认证:

  • 认证资质:ISO9001质量管理体系、IATF16949汽车电子认证、RoHS/REACH环保认证;

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
