CGA1206X5R475K500NT是HRE芯声电子推出的通用型多层陶瓷电容(MLCC),型号命名遵循行业标准规则:
HRE芯声作为国内专注MLCC研发的厂商,该产品针对中低压电路的滤波、耦合需求设计,兼具稳定性与成本优势,广泛适配消费电子、工业控制等领域。
容值标称4.7μF(编码475),精度±10%(K档),在常规工作环境下容量漂移可控,满足大多数电路对滤波/耦合容量的基础要求。
直流额定电压50V,交流电压需按行业降额规则使用(通常≤10Vrms),可覆盖中等电压等级的电源、信号电路。
X5R温度系数定义为:工作温度范围-55℃~+85℃,容量变化率±15%(25℃为基准)。对比Y5V(容量变化±20%)等低阶系数,X5R的温度稳定性更优,避免温度波动导致电路性能漂移。
采用1206表面贴装封装(SMT),是行业通用标准封装,适配绝大多数自动化贴装产线,贴装效率与兼容性突出。
符合RoHS 2.0、REACH指令,无铅无卤,满足全球电子设备的环保准入标准。
智能手机、平板电脑、智能穿戴设备的电源滤波(如电池管理电路)、信号耦合(如音频电路),适配小体积、中等容量需求。
PLC可编程控制器、变频器、传感器模块的直流滤波,X5R的温度稳定性可适应工业环境(-20℃~+60℃)的温度波动。
路由器、交换机、光模块的电源模块滤波,50V额定电压满足通信设备中等电压供电需求。
电动牙刷、智能音箱、智能家居控制器的控制电路滤波,低成本与稳定性能兼顾批量应用。
经加速寿命测试(125℃、1.5倍额定电压),连续工作≥1000小时无失效,满足常规应用的长期可靠性要求。
贴装后抗振动(频率10~2000Hz,加速度1.5g)、抗冲击(峰值加速度1000g),符合IPC-J-STD-001焊接标准与IEC 60068-2-6振动测试要求。
通过湿负荷测试(40℃、95%RH,50V直流加载),绝缘电阻保持≥10⁸Ω·μF,可适应潮湿环境(如南方地区电子设备)。
HRE芯声作为国内厂商,在同等X5R性能下,价格比进口品牌低15%~20%,适合中低端批量应用。
对比Y5V等低阶陶瓷电容,X5R的温度漂移更小,避免电路在温度变化时出现滤波不足或信号失真。
HRE具备年产能50亿只MLCC的生产能力,可满足客户长期稳定供货需求,减少供应链风险。
4.7μF容量、50V电压覆盖多领域电路的滤波/耦合需求,可替代同参数进口型号,降低选型复杂度。
综上,CGA1206X5R475K500NT是一款高性价比、通用型MLCC,适配多场景需求,适合追求成本与性能平衡的电子设备设计。
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.
