CGA1206C0G330J102MT是HRE(芯声)品牌推出的超稳定型高压多层陶瓷电容(MLCC),针对中高压精密电子电路设计,兼具容值稳定性、高耐压性与小体积特点,广泛适用于通信、医疗、工业控制等领域。
该产品属于HRE芯声C0G系列高压MLCC,型号命名可对应核心参数:
产品采用无铅工艺制造,符合RoHS环保标准,可兼容主流电子设备的焊接与组装流程。
1206表面贴装封装
采用无引脚SMD结构,适配回流焊、波峰焊工艺,焊接可靠性高;封装尺寸紧凑,可在高密度PCB上实现密集贴装,降低设备体积。
多层陶瓷叠层工艺
采用镍电极(Ni)与C0G陶瓷介质交替叠层,通过高温烧结形成一体化结构,电极层数与介质厚度精准控制,保证容值一致性与耐压性。
端电极优化设计
端电极采用三层结构(镍底层+铜中间层+锡顶层),兼容无铅焊接,抗热冲击能力强(可通过260℃回流焊10次循环测试),减少焊接开裂风险。
高频通信领域
用于基站射频模块、卫星通信设备的信号耦合、滤波与匹配网络,C0G的低损耗特性可保证高频信号传输质量,1kV耐压满足射频功放的电源滤波需求。
医疗电子设备
如高频理疗仪、医用测试仪器(示波器探头、信号发生器),其超稳定容值可确保医疗信号的精准度,避免因容值漂移导致的测量误差。
工业控制与高压电源
应用于PLC模块的高压滤波、传感器信号耦合,以及开关电源的尖峰抑制电路,1kV额定电压可直接匹配中高压电源系统,无需额外降压设计。
航空航天辅助电路
因宽温范围(-55℃~+125℃)与高可靠性,可用于航空机载设备的信号处理电路,满足极端环境下的稳定工作需求。
容值超稳定:C0G介质的温度系数≤±30ppm/℃,在全工作温度范围内,容值变化不超过0.l%,远优于X7R等中温稳定介质,适合精密电子系统。
高耐压小体积:1kV额定电压搭配1206封装,在中高压电路中实现“小体积大耐压”,解决传统高压电容体积过大的痛点。
低损耗高频适配:介质损耗DF≤0.15%,可支持100MHz以上高频信号传输,满足射频、微波等领域的低损耗需求。
可靠性高寿命长:无铅工艺与优化叠层结构,可通过1000小时高温高湿(85℃/85%RH)测试,典型MTBF(平均无故障时间)超过10⁶小时,适合长周期使用场景。
电压降额:直流应用建议将工作电压控制在额定电压的80%以下(≤800V),延长使用寿命;交流应用需按有效值降额(如交流500V有效值可直接使用,需参考 datasheet确认交流耐压值)。
焊接工艺:回流焊峰值温度需控制在230℃~245℃,焊接时间不超过10秒,避免热应力导致陶瓷开裂;波峰焊需采用惰性气体保护,减少氧化。
静电防护:虽C0G电容抗静电能力强于电解电容,但1kV高压型号仍需注意ESD防护(建议接地操作),避免静电击穿内部电极。
环境适配:避免在强磁场、强辐射环境下长期使用,若应用于车载场景,需确认振动/冲击测试是否符合相关标准(如MIL-STD-883)。
CGA1206C0G330J102MT凭借其稳定的性能与高压适配性,成为中高压精密电子电路的理想选型,可有效提升设备的可靠性与信号质量。
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.
