CSA0402C0G3R0C500GT是HRE芯声(HRE) 推出的高精度高频贴片电容,专为对容值精度、温度稳定性要求严苛的电子电路设计。核心参数明确:
该型号聚焦“小体积+高精度+宽温稳定”三大核心,适配各类小型化、高性能电子设备。
采用0402贴片封装(SMD),无引线设计,尺寸仅1.0mm(长)×0.5mm(宽)×0.5mm(高,典型值),重量约0.002g,可显著降低电路布局空间,满足智能手机、智能穿戴等便携设备的小型化需求。
封装材料兼容标准回流焊工艺:峰值温度260℃±5℃(焊接时间≤10秒),波峰焊温度245℃±5℃(时间≤5秒),无焊接兼容性问题;同时符合RoHS 2.0、REACH环保标准,不含铅、镉等有害物质,适配全球市场准入要求。
C0G温度系数为**±30ppm/℃**(IEC 60384-1标准),是陶瓷电容中温度稳定性最优的类别之一。在-55℃至+125℃的宽温范围内,容值变化率仅±0.15%(即3pF容值变化≤0.0045pF),远超X7R(±15%)、Y5V(±82%)等介质电容。
这一特性使产品可稳定工作于车载电子(-40℃+85℃)、工业控制(-25℃+85℃)等严苛环境,避免因温度变化导致的电路性能漂移。
基于“高精度、宽温稳定、小体积”的特点,该电容广泛适配以下场景:
HRE芯声对该产品实施全流程品质管控:
产品提供1年质保,支持定制化参数(如不同封装、电压等级)。
该型号以“小体积实现高精度宽温稳定”为核心优势,是高频、精密电子领域的实用型选择。

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.
