FN18X224K500PBG是PSA信昌电陶推出的通用型贴片多层陶瓷电容(MLCC),采用0603(英制)小型化封装,核心参数适配中低压通用电路需求,广泛覆盖消费电子、工业控制等领域,兼具小型化、宽温稳定性与高可靠性特点,是电子设备中滤波、耦合、去耦等场景的常用组件。
该型号电容的关键参数围绕“容值精度、耐压能力、温度稳定性”三个核心维度设计,具体如下:
容值标称220nF(对应容值代码“224”,即22×10⁴pF=220000pF=220nF),精度为**±10%**。该精度属于通用级,可满足大多数不需要极高容值稳定性的电路需求(如滤波、耦合、去耦等),避免因精度过高带来的成本冗余,同时覆盖常见电路对容值偏差的容忍范围。
直流额定电压为50V,是该电容的核心耐压指标——在额定工作温度范围内,可长期承受≤50V的直流电压;对于交流信号,其峰值电压需控制在50V以内(因陶瓷电容交流耐压与直流额定电压正相关,X7R介质的交流耐压通常不超过直流额定电压的85%),适配12V、24V、36V等低压电源系统。
采用X7R型陶瓷介质,符合EIA标准:
封装规格为0603(英制),对应公制尺寸1.6mm×0.8mm×0.8mm(长×宽×高),是电子设备小型化的主流封装之一:
PSA针对该型号采用成熟的MLCC生产工艺,确保长期稳定性:
结合参数特性,该电容适用于以下场景:
PSA信昌电陶是国内专业的MLCC研发生产企业,该型号具备以下优势:
综上,FN18X224K500PBG凭借小型化封装、宽温稳定性与高可靠性,成为中低压通用电路的优选MLCC组件,可覆盖多领域电子设备的核心电路需求。

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.
