0402B103K160NT 产品概述

一、产品简介

0402B103K160NT 是风华(FH)系列的一款片式多层陶瓷电容器,标称容量为 10nF(0.01µF),初始容差 ±10%(K),额定直流工作电压 16V,采用 X7R 温度特性陶瓷介质,封装规格为 0402(公制 1005,约 1.0mm × 0.5mm)。该器件面向高密度贴片电路,适用于一般去耦、旁路与滤波场合。

二、主要特性

  • 容值:10nF(0.01µF);初始容差 ±10%(K)
  • 额定电压:16V DC
  • 介质材料:X7R(-55°C 至 +125°C,温度范围内电容量变化属 X7R 特性)
  • 封装:0402(适配高密度 SMT 贴装)
  • 工艺:适用于常见无铅回流焊工艺,常见提供卷盘(Tape & Reel)包装,便于自动贴装

三、电气性能与设计注意事项

  • X7R 介质具有中等介电常数与温度稳定性,温度变化下电容量会有一定波动(X7R 规范下在工作温区内容值变化范围较宽),不适合需要高稳定性的时基或阻容精密电路。
  • DC 偏置效应:高介电常数陶瓷在施加直流电压时容量会下降,设计时应考虑实测在工作电压下的有效容量,尤其在接近额定电压时降额明显。
  • 频率与温度依赖:高频下等效电容可能有所变化;对高频旁路要求强的场合需关注等效串联电感(ESL)与等效串联电阻(ESR)。
  • 耐压与安全裕度:推荐在设计时保留适当裕度(例如工作电压低于额定电压),以提高长期稳定性与可靠性。

四、典型应用场景

  • MCU、SoC、PMIC 等供电轨的去耦与旁路(尤其 3.3V、5V 以及其他低电压电源)
  • EMI 滤波、电源输入去耦、旁路网络
  • 高频信号链路的局部解耦与退耦(在容值、频带允许范围内)
  • 消费电子、通信设备、可穿戴与物联网终端等对体积与高度有限制的产品

五、封装与工艺兼容性

  • 0402 小型封装适合高密度布板与微型化产品;但同时对贴装、回流与后焊工艺要求高,建议采用合适的锡膏印刷量与回流曲线(兼容主流无铅回流温度)。
  • 机械防护:0402 尺寸较小,对元件受力敏感,避免在元件上施加过大弯曲或机械应力(如边缘焊盘过窄或 PCB 弯曲)。
  • 焊盘设计建议参照厂商推荐的 land pattern,以保证可焊性与可靠性。

六、选型建议与可靠性

  • 若电路对容值稳定性要求高(时基、精密滤波等),建议优先考虑 C0G/NP0 或提高容值留裕;若为一般去耦、旁路,X7R 在体积与容值比上更具优势。
  • 考虑 DC 偏置与温度影响,必要时在原理图或 PCB 上留充足余量或并联不同类型电容以优化频率响应。
  • 风华作为国内知名被动元器件厂商,具备批量生产与质量控制能力,常见有相关可靠性测试与出货检验,具体可靠性数据建议参考风华官方数据手册。

七、总结

0402B103K160NT 提供在极小体积下较大容值的通用型解决方案,适合针对空间受限且需常规去耦、滤波的电子产品。在使用时应关注 X7R 的温度特性与 DC 偏置效应,合理留裕和优化布局可充分发挥其体积与成本优势。欲获取详细电气参数、温度/偏置曲线与封装尺寸建议,请参考风华官方规格书或向供应商索取样片与测量报告。

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
