FV43N221J102ECG是信昌电陶(PSA) 推出的一款Class I型贴片多层陶瓷电容(MLCC),采用1812英制封装(对应公制尺寸约4.5mm×3.2mm),适配自动化表面贴装工艺,可直接集成于各类电子设备的PCB板中。该产品定位于高压、高稳定场景,兼顾小型化与性能可靠性,是工业级、通信级电路的常用核心元件。
该电容的关键参数清晰明确,可精准匹配特定应用需求:
C0G温度系数是该电容的核心优势:相比Class II型电容(如X7R、Y5V),其容值随温度变化的漂移量可忽略不计。例如,在-40℃至+85℃的常规工作温区,容值变化不足0.1%,可确保电路在极端环境(如工业高温、低温户外)下性能一致,避免信号失真或功能异常。
1kV直流额定电压设计,配合PSA成熟的陶瓷介质配方与多层叠层工艺,具备优异的绝缘电阻(≥10¹⁰Ω),可有效抑制漏电流。即使在高压脉冲场景下,也能保持稳定的电气性能,满足高压电源滤波、EMI抑制等需求。
Class I型电容的损耗角正切(tanδ)极低(≤0.001),在1GHz以上射频频段仍能保持低损耗。这一特性使其适合振荡电路、射频匹配网络等高频应用,减少信号能量损耗,提升通信设备的信号传输质量。
1812封装体积适中:既避免了0402等小封装的容量限制,又比2220等大封装更节省PCB空间;同时适配自动化贴装设备,支持批量生产中的高效作业,降低人工成本。
产品符合RoHS2.0、REACH等国际环保指令,不含铅、镉等有害物质;出厂前经过严格可靠性测试(温度循环、湿度-温度偏压、焊接热冲击等),可在长期使用中保持性能稳定,降低设备维护成本。
该电容的特性使其适用于多个对稳定性、耐压性要求较高的领域:
作为信昌电陶的成熟产品,FV43N221J102ECG遵循IEC 60384-1、JIS C 5101等国际标准,全程质量管控:
该产品凭借高稳定、高耐压、低损耗等特性,成为高压高频电路的优选元件,可有效提升设备的可靠性与性能表现。

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.
