FM21N101J501PXG为PSA(信昌电陶)推出的C0G类多层片式陶瓷电容(MLCC),核心参数基于工业级设计,具体规格如下:
该产品针对中高压、宽温、高频场景优化,核心特性包括:
宽温下的容值稳定性
C0G温度系数使产品在极端温度环境(如工业高温区、户外设备)中容值漂移极小,避免因温度变化导致电路性能波动(如滤波截止频率偏移、信号耦合效率下降)。
低损耗与高频适配性
介质损耗角正切值(tanδ)≤0.15%(1kHz,25℃),在射频、微波电路中信号衰减小,适合信号耦合、阻抗匹配等高频应用。
中高压耐受能力
500V WVdc额定电压无需串联多个低耐压电容,简化电路设计,同时通过PSA的高温寿命测试(125℃/500V 1000h),确保长期高压下的可靠性。
小型化与焊接兼容性
0805封装体积小,适配高密度PCB设计(如便携式设备、通信基站模块);端电极采用“银-镍-锡”三层结构,增强焊接附着力,兼容回流焊(峰值温度≤245℃)、手工焊工艺。
该产品广泛应用于需要中高压、稳定容值、宽温可靠的领域:
PSA针对该产品执行严苛的可靠性测试,符合国际/国内标准:
FM21N101J501PXG凭借稳定的温度特性、中高压耐受能力及小型化设计,成为工业、通信等领域中高压滤波、信号耦合场景的高性价比选择。

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.
