CGA0201C0G470J500ET是HRE芯声推出的一款高性能商用级贴片多层陶瓷电容(MLCC),针对高频精密电路设计,兼顾小体积与高稳定性,广泛适配消费电子、工业控制及射频通信等领域。以下从核心参数、性能特性、封装规格等维度展开详细概述:
该型号为HRE芯声的标准MLCC产品,型号命名遵循行业通用规则,各段标识对应明确:
基础参数清晰:容值47pF±5%、额定电压50V、C0G温度系数、0201贴片封装,是中低压精密电路的常规高性价比选型。
C0G温度稳定性优势
C0G是陶瓷电容中温度特性最优的类别之一,温度系数为0±30ppm/℃,在-55℃至+125℃宽温范围内,容值变化率≤±0.3%,远优于X7R(±15%)等通用型电容。适合对容值一致性要求高的精密模拟电路、射频匹配电路。
低损耗与高频适配性
典型损耗角正切(DF)≤0.15%(1kHz/25℃),高频下(如2.4GHz)仍保持低ESR(等效串联电阻)与低ESL(等效串联电感),可有效减少信号衰减,适配蓝牙、WiFi等无线模块的滤波/耦合需求。
额定电压与绝缘可靠性
50V额定直流电压满足中低压电路需求,结合MLCC多层陶瓷结构的高绝缘性,绝缘电阻≥10¹⁰Ω(25℃/50V),可长期稳定工作于一般消费电子及工业环境。
该电容因小体积、高稳定性,主要适配以下场景:
HRE芯声是国内专注于高性能陶瓷电容研发的厂商,该型号通过多项可靠性测试:
综上,CGA0201C0G470J500ET是一款兼顾小体积与高稳定性的C0G型MLCC,适合对容值精度、温度特性要求较高的中低压电路,是消费电子、射频通信领域的可靠选型。

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.
