CIA0603X7R104K500JT 为 HRE(芯声) 系列的小型多层陶瓷电容,标称容量 100nF (0.1µF)、精度 ±10% (K)、额定电压 50V,介质为 X7R,封装尺寸 0603(英寸)。该产品适配表面贴装工艺,面向大批量自动化贴片生产与通用电子设计需求。
X7R 属于 Class II 高介电常数材料,单位体积具有较高电容量,适合在有限空间内提供较大电容值。相比 Class I(如 C0G/NP0),X7R 的稳定性和损耗略差,但性价比高。X7R 在温度范围内的电容变化受限于规范(典型在 ±15% 以内),需要注意直流偏压对有效电容的压降现象(DC bias effect),在高电压或严格滤波要求场合建议预留裕度。
0603 小尺寸封装适合高密度贴片。建议使用符合 IPC 标准的回流焊工艺及推荐温度曲线,避免反复高温回流导致性能退化。焊盘设计应参考封装尺寸留有足够焊接面,防止机械应力导致裂纹。元件在设计布局时,应注意电源旁路靠近电源管脚布置以降低回路阻抗。
HRE 系列产品通过严格的来料检验与工艺控制,适用于大规模量产。X7R 电容在温度与电场作用下存在容量漂移与损耗特性,关键应用建议进行设计验证(如寿命测试、温度循环、湿热与耐焊接热冲击测试)。产品通常满足常见环保规范(如 RoHS);具体认证资料可与供应商确认。

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.
