C1812N102J202T是禾伸堂(IHHEC)推出的高压高稳定型多层陶瓷贴片电容(MLCC),采用1812封装,针对宽温、高压、高精度场景设计,凭借C0G介质的温度稳定性与2kV额定电压的耐受能力,成为工业控制、射频通信、精密仪器等领域的核心被动元件之一。
该型号属于禾伸堂高压C0G系列MLCC,型号命名清晰对应关键参数:
产品定位为高压小容值、宽温高精度的通用型MLCC,适用于对容值稳定性、电压耐受要求严格的电路设计。
容值为1nF(1000pF),精度等级**±5%(J档)**——该精度可满足大多数工业级电路的容值匹配需求,无需额外校准即可实现稳定的滤波、耦合或匹配功能。
额定电压为2kV直流(DC),是核心高压特性:
采用C0G(NP0)陶瓷介质,温度系数≤±30ppm/℃,是MLCC中温度稳定性最优的介质类型:
1812封装为表面贴装式(SMD),公制尺寸:
兼容常规SMT回流焊工艺(符合IPC/J-STD-020标准),适合高密度PCB布局,支持小型化设备设计。
焊盘采用镍-锡(Ni-Sn)镀层,符合RoHS/REACH无铅环保要求,焊接附着力强;电极层为银-钯(Ag-Pd)合金,减少介质氧化与电极迁移风险。
区别于X7R、Y5V等温度敏感型介质,C0G具有:
禾伸堂采用多层共烧工艺(MLCC),介质层厚度均匀(≤10μm),电极层间距精准,确保2kV高压下的绝缘可靠性;同时通过激光微调优化容值精度,减少批量偏差。
开关电源、逆变器的高压侧滤波:滤除2kV DC电路中的高频噪声,避免干扰后级;
基站、雷达、卫星通信的射频匹配电路:利用低损耗、高Q值特性实现信号阻抗匹配;
示波器、信号发生器的前端电路:稳定容值确保信号采集精度,避免温度误差;
变频器、伺服系统的辅助高压电路:宽温(-40℃~85℃)环境下稳定工作,满足工业现场要求;
高压电源模块、诊断设备的高压控制电路:高可靠性与环保特性符合医疗安全标准。

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.
