CGA0402X7R104K350GT是芯声(HRE)针对低压小型化电路设计的多层陶瓷电容器(MLCC),主打滤波、耦合、去耦场景,兼顾容值密度与温度稳定性。核心参数如下:
X7R介质是陶瓷电容中“容值-温度”平衡的主流选择:相比Y5V(-30℃~+85℃,容变±20%)温度范围更广,相比NPO(容变±0.05%但容值<10nF)更适配高容值需求。该产品在-55℃至+125℃内,容值波动≤±15%,满足户外设备、工业高温环境的基本稳定要求。
1kHz测试下,损耗角正切值(tanδ)≤1%;10MHz以内仍保持低阻抗特性,适合射频前端耦合、电源线路高频滤波(如5G终端的PA模块去耦)。
0402封装仅1.0mm×0.5mm,比0603封装体积缩小60%,可显著降低PCB布局面积,适配智能手机、智能穿戴等小型化终端。
25℃下,额定电压(35V)时漏电流≤35nA(公式:0.01CV,C=100nF,V=35V),有效减少电池设备的静态耗电。
HRE针对0402小封装的工艺优化,提升可靠性与一致性:
该产品因“小体积+均衡性能”,广泛覆盖以下领域:
HRE通过全流程可靠性测试,符合行业标准:
该产品是低压小型化电路的高性价比选择,平衡了性能、体积与成本,适配多数消费电子及工业场景的基础需求。

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.
