型号:CGA0402C0G271J500GT
品牌:HRE(芯声)
封装:0402(英制,对应公制1005,尺寸1.0mm×0.5mm)
型号各部分含义拆解:
C0G属于低损耗、宽温稳定型陶瓷电容,温度系数≤±30ppm/℃,在-55℃~125℃范围内,容值变化率≤±0.3%——这是其区别于X7R(±15%)、Y5V(±82%)等温度敏感型电容的关键,直接决定了高频电路的频率精度。
标称容值270pF,精度±5%(J档),批量生产一致性优于标称(实际偏差多控制在±3%以内),无需额外校准即可稳定匹配电路需求。
直流额定电压50V,符合RoHS2.0环保标准;通过高温负载寿命测试(125℃、50V直流下,1000小时容值变化≤±2%,损耗角正切≤0.001),长期工作可靠性达标。
0402小封装适配高密度PCB设计(如智能手机主板、智能穿戴模块),焊接兼容性好(回流焊温度范围220℃~260℃),支持自动化贴片生产,适合批量组装。
结合参数优势,该电容主要用于以下场景:
HRE(芯声)是国内专注MLCC研发的品牌,该型号采用自主陶瓷配方,一致性优于进口同类产品(如村田GRM1555C1H271JA02D),交期稳定(常规715天),性价比提升15%20%,适合中高端消费电子与工业级应用。
该电容以“小体积+高稳定+低损耗”为核心竞争力,覆盖无线通信、智能终端等主流场景,是替代进口的高性价比选择。

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.
