HRE CGA0603C0G470J500JT是一款C0G介质多层陶瓷电容器(MLCC),型号各段含义清晰:
核心参数汇总:
参数项 数值/范围 标称容值 47pF 容值精度 ±5%(J级) 额定电压 50V DC 温度系数 C0G(-55℃~125℃容值变化≤0ppm/℃) 工作温度范围 -55℃~125℃ 封装尺寸 0603(1.6mm×0.8mm×0.8mm,典型) 介质类型 低损耗陶瓷(C0G类)C0G介质是MLCC中温度稳定性最优的类别之一,在-55℃至125℃宽温范围内,容值变化可忽略不计(≤±0ppm/℃)。这一特性使其能在温度波动场景下保持电性能一致,避免因容值漂移导致的电路性能下降。
C0G介质的损耗角正切(tanδ)典型值≤0.15%(1kHz下),高频Q值(品质因数)≥1000(1MHz下),信号传输损耗极低,适合高频信号的滤波、耦合与匹配,可有效减少信号衰减和相位失真。
与X7R、Y5V等介质不同,C0G介质的容值不受直流偏置电压影响(偏置下容值变化≤1%),在有直流分量的电路中仍能保持稳定,避免因偏置导致的容值下降。
0603封装体积小巧,可实现PCB高密度布局,适配便携式设备、小型化电子模块的设计需求;同时额定电压50V高于常规0603封装的35V/25V型号,覆盖更多中压应用场景。
采用表面贴装无引线设计,焊端为无铅锡镀层(符合RoHS 2.0、REACH标准),兼容回流焊、波峰焊工艺,焊接兼容性好;封装尺寸精度高,适合自动化贴装生产,生产效率稳定。
芯声(HRE)对该产品进行了严格测试:
不含铅、镉、汞等有害物质,符合全球绿色电子要求;电性能与国际主流品牌同类产品兼容,可直接替换,降低设计风险。
芯声(HRE)是国内专注陶瓷电容器研发的高新技术企业,拥有自主知识产权的材料配方与生产工艺,产品覆盖消费电子、工业、汽车等领域。该产品从原材料(高纯度陶瓷粉、银电极)到生产(流延、叠层、烧结)全程管控,每批次100%电性能测试(容值、损耗、耐压),确保一致性;同时提供技术支持与售后保障,可满足批量订单供货需求。
总结:HRE CGA0603C0G470J500JT是一款高性能、高可靠的C0G类MLCC,凭借超稳定温度特性、低损耗、无偏置效应等优势,广泛适配对电性能稳定性要求高的场景,是便携式设备、射频通信、精密仪器的理想选择。

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.
