UMK107B7474KAHTE 产品概述

一、产品简介

UMK107B7474KAHTE 是一款面向高密度电路板设计的多层陶瓷电容(MLCC),标称容值 470nF(0.47µF),容差 ±10%,额定电压 50V,介质温度特性 X7R,封装为 0603。由 TAIYO YUDEN(太阳诱电)生产,该型号在体积受限且需要中等至高电压耐受能力的应用中提供良好的去耦、滤波与耦合性能。

二、主要参数

  • 容值:470nF(0.47µF)
  • 容差:±10%
  • 额定电压:50V DC
  • 介质温度特性:X7R(通常在 −55°C 至 +125°C 范围内温度系数受控)
  • 封装:0603(约 1.6 mm × 0.8 mm)
  • 制造商:TAIYO YUDEN(太阳诱电)

三、特性与优点

  • 高容量密度:在 0603 小封装中实现 0.47µF,便于在空间受限的模块内布置更多元件或缩小外形尺寸。
  • 稳定的温度特性:X7R 介质在宽温区间内保持可接受的电容变化,适合一般功率旁路与滤波用途。
  • 50V 额定电压:比常见的 16V/25V 等级更适合中等电压系统或需要一定裕度的电源设计。
  • SMT 兼容:适用于主流回流焊工艺,便于自动化贴装与生产。

四、典型应用场景

  • 电源去耦与旁路:针对 MCU、电源管理芯片及功率模块附近的中等频率滤波与稳定。
  • DC-DC 转换器输入/输出滤波:在 50V 额定下可用于高于常规低压应用的中间母线或前端滤波。
  • 模拟电路的耦合/旁路:为放大器、ADC 等器件提供局部能量储备与噪声抑制。
  • 工业与汽车电子(视认证与可靠性等级而定):在耐温要求不超出 X7R 范围时可作为通用电容方案。

五、封装与机械信息

  • 封装尺寸:0603(约 1.6 mm × 0.8 mm)——适合高密度 PCB 布局。
  • 焊接与可靠性:兼容标准无铅回流焊(请参考厂商推荐的回流曲线以避免热应力导致裂纹或性能退化)。
  • 机械强度:小尺寸封装在波峰或回流焊操作及强振动环境下需要注意 PCB 支撑与焊点设计,避免大应力集中。

六、选型与设计注意事项

  • 电压偏置效应:X7R 型陶瓷电容在施加直流偏压时会出现电容下降(随材料与厚度不同而异),50V 额定下实际工作电容可能降低,设计时请参考厂商 DC bias 曲线并适当留裕量。
  • 温度与频率特性:X7R 在极端温度下电容有可观变化(但仍在工业可接受范围内);高频下等效串联电感(ESL)与 ESR 会影响滤波性能,必要时组合不同封装/不同电容值以优化响应。
  • 焊接工艺:遵循制造商的回流温度曲线与前处理建议,避免过高峰值温度和多次重工,以降低裂纹与失效风险。
  • 库存与储存:避免潮湿与剧烈温度变化,必要时施行干燥箱存放与烘烤预处理,尤其在受潮后进行回流会导致焊接缺陷。

七、可靠性与质量保证

此类器件通常通过行业标准的质量与可靠性测试,包括温度循环、高温高湿、加速寿命试验等。具体的寿命数据、故障率与认证项(如 AEC-Q100/200 等)请以 TAIYO YUDEN 官方数据手册为准。批量采购时建议索取样品做实际焊接与电气测试验证,确认在目标应用下的长期稳定性。

八、采购与包装信息

  • 标准包装:常见为卷盘(tape & reel)包装,适合自动贴片生产线。
  • 订购注意:确认包装单位(如 2k/4k/10k 卷盘)、最小起订量与可追溯的批号信息,以便质量追溯与生产一致性。
  • 替代与匹配:若需替代产品,应在容值、容差、额定电压、介质特性(X7R)和封装尺寸上尽量匹配,并关注 DC bias 与温度响应的差异。

总结:UMK107B7474KAHTE 在 0603 小型封装中以 0.47µF/50V/X7R 的组合,为对空间与电压有中等要求的电子系统提供了平衡的去耦与滤波解决方案。最终选型应结合电压偏置曲线、工作温度范围与焊接工艺验证,确保在目标应用中达到预期性能与可靠性。

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.
