CGA0402C0G330J500GT是芯声电子(HRE) 推出的Class 1类高频低损耗多层陶瓷电容器(MLCC),专为小型化、高稳定性电子电路设计,核心参数明确:
该产品定位于对容值稳定性、高频损耗要求严苛的领域,替代Class 2电容的参数漂移问题,同时兼顾高密度贴装需求。
封装物理尺寸为长1.00±0.10mm × 宽0.50±0.10mm × 厚0.50±0.10mm,符合EIA-481标准,适配主流SMT贴片机(最小贴装精度±0.05mm),适合手机主板、TWS耳机等高密度PCB布局。
Class 1类C0G陶瓷特性赋予该产品高频场景核心优势:
C0G陶瓷温度系数为**±30ppm/℃(-55℃~125℃)**,容值随温度变化极小(相对于25℃,偏差≤±0.03%),远优于Class 2电容(如X7R偏差±15%)。宽温环境下(汽车电子、工业控制)仍能保持电路参数稳定,避免温度波动导致的信号失真。
该产品因小型化、高稳定、低损耗,广泛应用于:
HRE通过多重测试确保产品可靠性:
该产品平衡小型化、稳定性与成本,是替代进口同规格电容的高性价比选择,覆盖消费电子到工业级多场景需求。

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.
