0603B104K250NT 产品概述

一、产品简介

0603B104K250NT 是风华(FH)生产的一款多层陶瓷贴片电容(MLCC),标称电容值 100nF(104),公差 ±10%(K),额定电压 25V,介质类型为 X7R,封装尺寸为 0603(1.6 mm × 0.8 mm)。该系列为通用型中高介电常数陶瓷电容,具有体积小、可靠性高、寄生电感和等效串联电阻(ESR)低等优点,适合表面贴装自动化生产。

二、主要规格与物理参数

  • 容值:100 nF(0.1 μF)
  • 精度:±10%(K)
  • 额定电压:25 V DC
  • 介质:X7R(-55 °C ~ +125 °C,温度下电容量变化范围符合 X7R 规范)
  • 封装:0603(1.6 mm × 0.8 mm)
  • 封装形式:卷带供料(Tape & Reel),型号末尾 NT 通常表示卷带包装,便于贴片机上料
  • 外观:双端金属电极,适用于回流焊工艺

三、性能特点

  • 频率响应好:X7R 陶瓷材料在中高频范围具有良好电介质特性,适合去耦和滤波应用。
  • 体积小、容量密度高:0603 封装在有限PCB面积内能提供 100nF 容值,有利于高密度设计。
  • 低 ESR、低 ESL:有助于抑制电源噪声和瞬态干扰,提高电源稳定性。
  • 机械强度好:适合自动贴装与回流焊制造流程。
  • 宽温度范围:X7R 规范允许在 -55 °C 至 +125 °C 条件下工作,适应多数工业与消费类环境。

四、应用场景

  • 电源去耦/旁路:用于 MCU、FPGA、ASIC、电源模块等器件的本地去耦,减小电源纹波与瞬态电压尖峰。
  • 滤波与耦合:用于 EMI 滤波、信号链的耦合/旁路电容。
  • 降噪与稳定:开关电源输入/输出滤波,DC-DC 降压/升压模块的稳定与环路补偿(需注意 X7R 的非线性特性)。
  • 通信设备、消费电子、工控产品、便携式设备等场景的常规去耦与滤波元件(若用于汽车或航空等高可靠环境,请确认是否符合相应认证和等级要求)。

五、设计与使用建议

  • 电压偏置效应:X7R 型陶瓷电容在直流偏置下电容值会下降(尤其是较大介电常数和小体积组合时更明显)。在关键应用中应参考厂商电压-电容曲线,必要时进行裕量设计或选择更高额定电压器件。
  • 温度与老化:X7R 会随温度变化产生容值漂移,且存在老化(随时间呈对数规律下降)。在要求高稳定性的场合考虑使用 NP0/C0G 或其他稳定介质。
  • 焊接与回流:建议按照风华提供的回流焊温度曲线进行焊接,避免超温或长时间高温,以降低损坏风险。贴装前后注意防潮处理,遵循厂商的防潮包装与回流前回潮烘烤建议。
  • PCB 布局:去耦电容尽量靠近被去耦器件的电源引脚放置,尽可能减短走线,减小环路面积以获得最佳滤波效果。
  • 储存与搬运:避免机械挤压和强烈振动,运输与储存环境应干燥避潮,揭膜后应在厂商建议时间内回流焊接。

六、可靠性与质量控制

风华作为成熟的元器件供应商,对 MLCC 的制造与质量控制具有严格流程。产品在出厂前通常经过电容、电阻、外观等在线与离线检测;卷带包装适合 SMT 自动化生产。对于关键或高可靠性项目,建议索取并查看风华的具体数据手册、AEC-Q 或其他可靠性测试报告(如温度循环、湿热、机械冲击等)以确认符合项目需求。

七、订购信息与型号说明

  • 常用标识示例:0603B104K250NT
    • “0603” 表示封装尺寸
    • “104” 表示容值 100nF(10^4 pF)
    • “K” 表示 ±10% 公差
    • “250” 表示 25V 额定电压
    • “NT” 通常表示卷带包装方式
  • 订购时请注意核对完整料号、批次、包装单位及出厂测试报告,如需大量采购可与供应商确认交货期与库存。

如需进一步的电气特性曲线(频率响应、温度系数、电压偏置曲线、ESR/ESL 数据)、建议封装焊盘尺寸或详细可靠性数据,请提供是否需要数据手册或索取风华官方规格书,我可协助获取或解析具体参数。

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
