0402B101K500CT 片式陶瓷电容产品概述

一、产品基本信息

0402B101K500CT是华新科(Walsin) 推出的一款片式多层陶瓷电容(MLCC),型号各段含义清晰:

  • 「0402」:英制封装尺寸,对应公制规格为1.0mm×0.5mm(长×宽);
  • 「101」:容值编码,代表10×10¹=100pF;
  • 「K」:精度等级,对应±10%;
  • 「500」:额定直流电压,为50V;
  • 「CT」:华新科针对该产品的特定后缀标识,用于区分生产工艺或批次细节。

该产品定位为常规中温稳定型MLCC,适配多数电子设备的基础滤波、耦合需求。

二、核心电气性能参数

2.1 容值与精度

标称容值100pF,精度±10%,满足90%以上常规电路的容值误差要求(如电源滤波、信号耦合),无需高精度校准即可稳定工作。

2.2 额定电压

额定直流电压50V,实际使用需遵循80%~90%降额原则(即工作电压≤45V),可避免介质老化加速,延长产品寿命。

2.3 温度特性(X7R)

温度系数为X7R,是MLCC中经典的中温稳定介质:

  • 工作温度范围:-55℃~+125℃;
  • 容值漂移:全温度范围内≤±15%(典型值),远优于Y5V等低成本介质,适合宽温环境应用。

2.4 损耗特性

典型损耗角正切(tanδ)≤2%(测试条件:1kHz、25℃),信号传输过程中能量损耗低,适配音频、射频辅助滤波等场景。

三、物理与封装特性

3.1 封装尺寸

0402封装体积小巧(长1.0mm×宽0.5mm×厚≈0.5mm),可大幅节省PCB布局空间,适配智能穿戴、小型通信模块等高密度设计。

3.2 结构与工艺

采用多层陶瓷介质叠层结构:

  • 内电极:镍基材料,成本与性能平衡;
  • 外电极:无铅锡镀层(符合RoHS指令),环保且焊接兼容性好;
  • 优势:无引线寄生效应,高频性能优异;多层结构提升容值密度,小体积实现100pF容值。

3.3 焊接兼容性

支持回流焊、波峰焊等常规表面贴装工艺,焊接温度曲线需符合华新科推荐(峰值温度230℃~245℃,回流时间≤60秒),避免热冲击导致性能下降。

四、主要应用场景

结合参数特性,该产品适用于以下场景:

  1. 消费电子:手机、平板、智能手表的电源滤波、音频信号耦合;
  2. 工业控制:小型PLC、传感器模块的去耦与干扰滤波;
  3. 通信设备:路由器、无线AP的电源模块滤波;
  4. 汽车电子(辅助电路):车载显示屏、胎压传感器的低温环境信号处理;
  5. 小型家电:智能音箱、电动牙刷的控制电路滤波。

五、可靠性与环境适应性

5.1 温湿度耐受

工作温度-55℃~+125℃,湿度≤95%(非凝露),可适应工业现场、户外设备等宽温湿度变化。

5.2 寿命与稳定性

额定条件下寿命达数万小时,长期使用中容值、损耗变化极小,符合IEC 60384-1国际标准。

5.3 抗机械应力

片式封装抗振动性能优异(振动频率10Hz2000Hz,加速度10g20g),可承受运输、安装中的机械冲击。

六、选型与使用注意事项

  1. 电压降额:工作电压≤45V(额定电压90%),避免过压击穿;
  2. 温度限制:禁止长期超+125℃工作,防止容值漂移;
  3. 焊接工艺:严格遵循华新科回流焊曲线,避免局部过热;
  4. 直流偏置影响:X7R在直流偏置下容值下降≤10%,设计需预留余量;
  5. 存储条件:未开封产品存于-20℃~+40℃、湿度≤60%环境,开封后12个月内使用。

该产品凭借稳定的X7R特性、小体积封装与高可靠性,成为电子设备基础电路的主流选型之一。

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
