CGA0402X7R471K500GT是HRE芯声推出的通用型贴片多层陶瓷电容(MLCC),聚焦中低压电路的滤波、耦合与去耦场景。其命名规则清晰传递核心参数:
产品定位为高密度电路的成本优化型电容,适配消费电子、工业控制等多领域,平衡小型化与性能稳定性。
标称470pF(471),精度±10%(K档)——满足80%以上通用电路的容值需求(如电源滤波、信号耦合),无需为高精度场景支付额外成本,同时避免容值偏差对电路功能的影响。
50V直流额定电压——适用于5V/12V电源电路、10V以下信号处理模块,覆盖消费电子(手机、平板)与工业控制(PLC)的主流电压范围;交流场合需注意峰值电压降额(Vp=√2×Vrms≤50V)。
对比Y5V(容值变化±20%以上)、C0G(高精度但成本高),X7R的核心优势是宽温稳定性:
公制1005封装(1.0mm×0.5mm)是目前消费电子的主流小型化封装,支持PCB板高密度布局(如智能手机主板可集成数千颗),同时适配自动化贴装设备,提升生产效率。
采用叠层印刷工艺:将陶瓷介质(钛酸钡基)与镍内电极交替叠层,烧结后形成一体化结构——无引线设计降低ESR(等效串联电阻)与ESL(等效串联电感),适合高频信号传输(1GHz以下)。
X7R特性确保-55℃~+125℃范围内容值波动小,避免极端温度下电路功能失效(如冬季户外设备、夏季车载显示屏)。
典型ESR值≤5mΩ(1kHz),ESL≤0.5nH——适合1GHz以下高频电路,减少信号反射与损耗,提升射频性能。
对比C0G高精度电容(成本高30%以上),X7R在保证基础稳定性的前提下,降低终端产品的被动元件成本,适合中低端至中端市场。
MLCC为静电敏感元件(ESD等级2kV~4kV),生产/存储需:
综上,CGA0402X7R471K500GT是一款高性价比通用MLCC,凭借小型化、宽温稳定、低损耗等特性,成为消费电子与工业控制领域的主流选型之一。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
