该产品为HRE芯声推出的高压高频多层陶瓷电容器(MLCC),核心定位是满足对容值稳定性、耐高压性能要求较高的工业与射频应用。
标称容值1nF(102),精度等级为J级,即容值偏差控制在**±5%** 以内,满足大多数工业控制、射频电路的精度需求。
额定电压1000V DC,是该产品的核心优势之一——针对高压场景优化了陶瓷材料与电极结构,可稳定工作在高电压环境下,无需额外并联高压组件。
采用C0G(NP0)陶瓷材料,温度系数为**±30ppm/℃,容值随温度变化极小:在-55℃至125℃的宽温域内,容值变化不超过±0.3%**,完全适配极端环境下的精密电路。
采用高精度多层陶瓷叠层工艺,通过控制每层陶瓷与电极的厚度一致性,减少寄生参数(等效串联电阻ESR、等效串联电感ESL),提升高频响应速度。
针对1000V额定电压,选用高介电强度的C0G陶瓷材料,同时优化电极间距与端电极结构,避免高压下的击穿风险,同时保持1206封装的小型化优势。
端电极采用无铅锡基合金,符合RoHS 2.0与REACH环保标准,可用于医疗、消费电子等对环保要求严格的领域。
如工业开关电源、医疗设备(X光机、核磁共振)高压电源的纹波抑制回路,1000V额定电压可直接适配高压输出端,无需降额过度。
通信基站射频前端的耦合电容、谐振回路电容,C0G的低损耗与高稳定性确保信号无失真传输;卫星通信设备的微波组件也可选用。
变频器、PLC的高压信号耦合与滤波,宽温域(-55℃~125℃)适应工厂车间的极端温度变化,高可靠性减少设备故障。
卫星、无人机的辅助电源滤波与信号耦合,C0G的容值稳定性可应对太空环境的温度波动,提升系统可靠性。
高压MLCC建议降额50%以上使用(实际工作电压≤500V DC),避免过压导致陶瓷击穿;若为脉冲电压,需进一步降额至30%以内。
陶瓷电容易碎,安装时避免挤压、弯曲PCB;焊接后不要施加机械力(如插拔连接器),防止电容开裂。
常温(15~35℃)、干燥(相对湿度≤60%)环境储存,避免受潮影响端电极焊接性能;开封后建议1个月内使用完毕。
该产品凭借高压、高稳定、小型化的特点,可广泛适配工业、医疗、通信等领域的高压高频电路,是替代进口高压MLCC的高性价比选择。

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.
