CGA0201X5R104K250ET是HRE芯声电子推出的一款常规型贴片多层陶瓷电容(MLCC),主要面向消费电子、小型家电及工业低功耗模块等场景,以紧凑封装、稳定性能和高性价比为核心特点,满足电路中滤波、耦合、去耦等基础需求。
该型号属于HRE芯声的X5R系列MLCC,采用英制0201封装(对应公制尺寸约0.5mm×0.25mm),是目前小型化电子设备中应用最广泛的封装规格之一。型号命名逻辑清晰:
标称容值为100nF(104),容值精度**±10%(K档)**,满足大多数常规电路对容值偏差的要求(如电源滤波、小信号耦合等场景无需更高精度)。实际应用中,容值随电压、温度的波动在额定参数范围内可控(25V下容值变化≤±5%,X5R温度范围内变化≤±15%)。
采用英制0201贴片封装,尺寸仅为0.508mm(长)×0.254mm(宽)×0.254mm(厚,典型值),相比0402封装体积缩小约75%,能显著节省PCB空间,适配手机、智能手环等超小型电子设备的高密度布局。
通过多层陶瓷介质与内电极交替叠层烧结而成,相比单层陶瓷电容,相同体积下容值提升数十倍,同时具有高频特性好、稳定性高的特点。内电极采用银钯合金(Ag-Pd),兼容主流回流焊工艺,焊接温度窗口宽(220℃-260℃),不易出现虚焊、立碑或桥接问题。
端电极采用三层结构(镍层+锡层+镍层),表面镀锡工艺适配无铅焊接要求,符合RoHS环保标准;同时增强了焊接附着力与抗腐蚀能力,延长产品使用寿命(典型寿命≥10⁶小时)。
CGA0201X5R104K250ET因体积小、容值适中、成本可控,广泛应用于以下场景:
X5R温度系数确保在-55℃至+85℃范围内容值波动≤±15%,25V额定电压满足大多数低压电路需求(如3.3V、5V系统),无需额外降额过多,简化电路设计。
作为常规容量规格(100nF),该型号产量大、成本低,适合批量采购;0201封装适配自动化贴装线,生产效率高,降低终端产品制造成本。
符合RoHS、REACH等环保标准,无铅焊接兼容;经过HRE芯声的可靠性测试(如高温存储、温度循环、焊接冲击等),平均无故障时间(MTBF)≥10⁶小时,满足工业级与消费级产品的可靠性要求。
总结:CGA0201X5R104K250ET是一款性能均衡、封装紧凑、性价比高的常规MLCC,适合大多数低压、小型化电子设备的基础电容需求,是消费电子、智能家居等领域的主流选型之一。

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.
