CGA0402X7R102J500GT(品牌:HRE / 芯声)为贴片多层陶瓷电容器(MLCC),容值 1nF,精度 ±5%(J),额定电压 50V,介质材料 X7R,封装规格 0402(约 1.0 mm × 0.5 mm)。该型号属于通用型中介电常数陶瓷电容,体积小、可靠性高,适合大批量表面贴装生产。
0402 封装体积极小,适用于高密度 PCB 布局,适合移动设备与消费类电子的去耦、滤波等用途。小尺寸带来的机械应力敏感性较高,焊接、回流工艺与 PCB 布局需按厂商推荐的焊盘尺寸和回流曲线执行,以避免芯片应力导致裂纹或失效。
在干燥、常温环境下储存,避免受潮与机械冲击;长期库存建议做烘烤处理以消除吸湿。使用过程中注意避免 PCB 弯曲或强力擦拭,以降低裂纹风险。符合常见的可靠性测试(如温度循环、湿热、机械冲击)要求,但具体可靠性数据应以厂商数据手册为准。
若电路对温漂与电压依赖敏感,优先考虑 NP0/C0G 虑件;若需要更高容值或更小体积,可在 X5R/X7R 系列中比较不同封装与额定电压组合以平衡 DC bias 与体积需求。CGA0402X7R102J500GT 以其小尺寸和 50V 的电压等级,适合中高电压但要求体积受限的去耦与滤波场合。
如需进一步的电气曲线(温度依赖、DC bias 曲线、等效串联电阻 ESR/ESL)、机械尺寸图或回流建议,请提供样品需求或索取厂方 Datasheet,以便获得完整可靠的数据支持。

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.
