CSA0805X7R473K500KT 产品概述

一、产品简介

CSA0805X7R473K500KT 是 HRE(芯声)品牌的一款贴片多层陶瓷电容(MLCC)。器件采用 0805 封装,容值 47nF,公差 ±10%,额定电压 50V,温度特性为 X7R。该型号在体积、容量与可靠性之间取得平衡,适合通用去耦、旁路与滤波场合。

二、主要参数

  • 容值:47nF(473)
  • 公差:±10%(K)
  • 额定电压:50V
  • 温度系数:X7R(-55°C 至 +125°C,容值允差约 ±15%)
  • 封装:0805(2012公制)
  • 包装形式:常见为卷带(tape & reel)

三、性能特点

X7R 介质在宽温区间内保持较稳定的电容特性,适用于中低精度电路。0805 尺寸兼顾贴装可靠性与 PCB 布局密度,焊接工艺成熟。50V 额定电压使其能用于多数模拟与数字电源线路,47nF 的容量常见于去耦、旁路、RC 时间常数及耦合电路。器件具有良好的机械强度与可重复回流焊适应性。

四、典型应用

  • PCB 电源去耦与旁路
  • 电源滤波、降噪电路
  • RC 滤波与时间常数电路
  • 模拟输入耦合与旁路
  • 消费电子、通信设备、工控与汽车电子(视具体认证)

五、选型与使用注意

选型时应关注电压依赖性与温度特性:X7R 在高偏压下会有一定容值下降(DC bias effect),若电路对容量敏感可考虑提高额定电压或换用介质差异更小的型号;焊接需遵循厂商回流曲线,避免温度冲击造成陶瓷裂纹;布局上去耦电容应尽量靠近电源引脚并缩短回流路径,以降低寄生电感。存储与使用时注意防潮、防机械应力。

六、可靠性与供应

HRE(芯声)提供 RoHS 合规产品,并可依据需求提供出货溯源与可靠性测试报告(如温湿热、热冲击及振动测试)。0805 封装适合自动贴装与大批量生产,供应渠道稳定,适用于样机验证到量产导入的各个阶段。

如需进一步的电气特性曲线(温度/频率依赖、DC bias 曲线)、封装图或回流焊工艺建议,可提供具体用途以便给出更精确的建议。

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
