FN21X471K500PXG是PSA信昌电陶推出的一款通用型贴片多层陶瓷电容(MLCC),针对中低压电路的滤波、耦合、去耦等基础需求设计,具备容值稳定、适用温度范围宽、贴装兼容性强等特点,是消费电子、工业控制等领域的常规选型元件。
该型号属于PSA信昌电陶的标准MLCC产品线,采用0805封装,介质类型为X7R,是一款平衡容值稳定性与成本的通用电容。其设计目标是满足大多数电子设备中对中容值(pF级)、中低压(≤50V)、宽温度范围的电路需求——既避免了高精度介质(如COG)的成本冗余,也优于高容变介质(如Y5V)的性能表现,属于市场主流的“性价比均衡型”MLCC。
0805封装是MLCC的主流小尺寸封装之一,适合高密度PCB布局。该型号的物理特性还包括:
X7R介质的核心优势在于宽温度范围下的容值可控性:
PSA信昌电陶是国内MLCC领域的成熟制造商,具备稳定的产能与品质管控体系:
FN21X471K500PXG的参数特性使其适用于以下场景:
该型号作为PSA信昌电陶的成熟产品,在市场上具备广泛的应用基础,适合对成本敏感且需要宽温度稳定性的电子设备选型。

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.
