0402B104K100NT 产品概述

一、产品简介

0402B104K100NT 为风华(FH)系列贴片多层陶瓷电容(MLCC),标称容量 100nF(104),容差 ±10%(K),额定电压 10V,介质材料为 X7R,封装为 0402(约 1.0 mm × 0.5 mm)。该器件以体积极小、工作温度范围宽、适合表面贴装回流焊工艺为主要特点,常用于移动终端、消费电子、微型电源滤波与去耦场景。

二、主要性能与参数

  • 容值:100nF(0.1μF),精度 ±10%
  • 额定电压:10V DC
  • 介质:X7R(温度系数,工作温度范围通常为 −55°C 至 +125°C)
  • 封装:0402(约 1.0 mm × 0.5 mm)SMD
  • 品牌:风华(FH)
  • 温特性:X7R 属于 II 类陶瓷介质,温度范围内电容量变化可控,适合一般去耦与旁路用途
  • 电气特性:低 ESR/ESL,适合高频去耦;需注意直流偏压(DC bias)效应,工作电压下电容值会随电压上升出现一定下降

三、产品特点(优势)

  1. 体积小、比容高:0402 封装在体积受限的 PCB 上可提供较高的电容密度,适合便携式设备与高密度板设计。
  2. 良好温度稳定性:X7R 介质在 −55°C 至 +125°C 范围内具有可接受的电容变化,适用于一般工业与消费类温度环境。
  3. 适配自动化贴装:0402 封装兼容常见的贴片机与回流焊工艺,工艺可靠且良率高。
  4. 低等效串联阻抗:在高频去耦场合表现优异,能有效抑制电源噪声与瞬态尖峰。
  5. 品牌与质量保障:风华作为知名元件厂商,产品出厂前经过外观与电气参数检验,可靠性良好。

四、典型应用场景

  • 电源旁路与去耦:微处理器、模拟电路、功率管理芯片的近端去耦。
  • 高频滤波:与电感结合构成 EMI 抑制或电源滤波网络。
  • 移动与便携设备:智能手机、平板、穿戴设备等对小尺寸、高密度电容的需求场景。
  • 工业与通信终端:用于 PCB 上的分流、耦合与电源稳定场合。
    (注:对温漂与高精度电容要求高的信号路径,应选用 C0G/NP0 等一类介质。)

五、设计与使用建议

  • PCB 布局:将电容尽量靠近被去耦器件的电源引脚放置,缩短引线/走线长度以降低 ESL 与寄生电阻。
  • 并联使用:在需要更低 ESR/ESL 或更大瞬态电流供应时,可将多只相同或不同容值的 MLCC 并联使用,以获得宽频带的滤波效果。
  • 考虑直流偏压效应:X7R 在工作电压下电容量会下降,特别是较小封装在较高偏压时更明显;电路设计时应留有裕量,必要可选择额定电压更高或更大尺寸的器件。
  • 焊接工艺:适用于无铅回流焊,建议遵循厂商推荐回流曲线(峰值温度通常 ≤ 260°C);避免多次超温循环导致应力积累。
  • 机械应力防护:0402 为超小尺寸封装,对焊接冷却收缩或机械弯曲敏感,布板、夹具与波峰/回流工艺应尽量减少板弯与热应力。

六、可靠性与注意事项

  • 寿命与老化:X7R 的介电常数随时间有微小老化,长期稳定性优于 Z5U 类但不及 C0G,重要模拟前端与计量路径应谨慎选型。
  • 温度与频率特性:在极端温度或高频条件下电容性能会发生变化,必要时需通过仿真或样机测试验证。
  • 储存与搬运:超小封装在搬运与贴装过程中易受损,建议保持干燥包装并按 ESD、防潮工艺执行。

七、采购与选型建议

  • 型号:0402B104K100NT(风华)—— 下单时请核对完整料号及包装方式(卷盘数量、端接类型等)。
  • 若需更严格的温度稳定性或极低电容变化,应考虑 C0G/NP0 系列;若需更高工作电压或更低 DC bias 效应,可选更大封装或更高额定电压型号。
  • 在高速或射频路径上使用时,请一并关注等效串联电感(ESL)与自谐频率,以保证滤波效果达标。

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.
