CGA0402X5R474K500GT是国内电子元器件品牌HRE芯声推出的一款0402封装多层陶瓷电容器(MLCC),核心面向小型化、中等电压需求的电子设备设计。其型号命名遵循行业通用规则,各部分含义清晰:
该产品的关键参数针对中等复杂度电路需求优化,具体价值如下:
容值为470nF(0.47μF),精度±10%(K级),既避免容值过小导致滤波效果不足,也通过±10%精度控制降低电路匹配难度——可直接用于电源滤波、信号耦合等基础电路,无需额外匹配补偿。
额定直流电压为50V,适用于中等电压场景(如12V/24V系统二次滤波、小型电源模块储能)。按行业1.5倍降额规则,实际可覆盖33V以下工作电压,适配多数消费电子、工业设备的电压范围,同时避免过压击穿风险。
0402(1005)封装体积仅为1.0mm×0.5mm×0.5mm(典型值),是小型化设备的核心适配方案:可显著减少PCB占用面积(比0603封装节省60%以上空间),适合智能手机、可穿戴设备、小型通信模块等对空间敏感的应用。
X5R是该产品的核心材料特性,其定义为:工作温度范围-55℃~+85℃,容值变化±15%,在MLCC材料中属于“平衡型”特性,相比其他常见温度系数有明显优势:
HRE芯声针对该产品采用成熟的MLCC生产工艺,确保长期可靠性:
该产品因体积小、容值适中、温变稳定,广泛应用于以下领域:
HRE芯声作为国内专注MLCC研发生产的厂商,拥有10余年行业经验,产品线覆盖02011206封装、1pF100μF容值,产品通过ISO9001质量体系认证,部分规格符合IATF16949汽车电子标准。针对该产品,HRE提供:
该产品以“小体积+实用容值+宽温稳定”为核心优势,是消费电子、工业控制等领域小型化电路设计的高性价比选择。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
