CSA0805X7R105K500MT 贴片电容产品概述
一、产品核心身份与型号解析
CSA0805X7R105K500MT是HRE芯声推出的通用型贴片陶瓷电容，型号各段明确对应核心特性：
- 「0805」：英制封装（公制2012，即2.0mm×1.25mm）；
- 「X7R」：温度系数标识，代表工作温度与容值稳定性；
- 「105K」：容值编码（10×10⁵pF=1μF），K=±10%精度；
- 「500」：额定直流电压50V；
- 「MT」：编带包装标准规格。
该型号直接匹配用户需求参数，是芯声通用电容系列的主力型号。
二、关键电气性能参数
参数项 具体指标 说明 标称容值 1μF（105K） 实际范围：0.9μF~1.1μF（±10%精度） 额定直流电压（Vdc） 50V 交流电压下需降额（峰值≤35V，即70%额定值） 温度系数 X7R 工作温度：-55℃~+125℃；容值变化≤±15%（远优于Y5V介质） 损耗角正切（tanδ） ≤2%（1kHz，25℃） 低损耗适合信号传输与滤波 绝缘电阻（IR） ≥10⁹Ω（25℃，50V DC） 高绝缘减少漏电流，提升电路稳定性三、封装与物理特性
采用0805（2012）表面贴装封装，细节如下：
- 物理尺寸：长2.0±0.2mm，宽1.25±0.15mm，厚0.8±0.1mm（典型值）；
- 包装方式：1000个/180mm×300mm标准卷盘，编带方向统一，适配自动化贴装；
- 焊接兼容性：支持回流焊（峰值≤260℃，3秒内）、波峰焊（≤240℃），符合IPC标准。
四、温度特性与稳定性
X7R是陶瓷电容中温度稳定性较好的介质，优势明显：
- 极端温度容值波动小：-55℃时下降≤15%，+125℃时上升≤15%（Y5V波动达±80%）；
- 长期可靠性：通过125℃/1000小时高温寿命测试，容值变化≤±5%，损耗变化≤±20%，满足工业级需求。
五、品牌与可靠性保障
HRE芯声是国内专业被动元器件厂商，该型号通过多项认证：
- 环保认证：RoHS 2.0、REACH（无铅无卤）；
- 可靠性测试：温度循环（-55℃+125℃，500次）、湿度负荷（85℃/85%RH，1000小时）、振动测试（102000Hz，1.5g）；
- 量产一致性：自动化生产，批次参数波动≤±3%，适合大规模量产。
六、典型应用场景
因性能均衡、成本适中，广泛用于：
- 电源滤波：开关电源、DC-DC转换器的输入/输出滤波，抑制纹波；
- 信号耦合：音频、射频前端的信号耦合，减少损耗；
- 芯片去耦：MCU、FPGA的电源去耦，稳定供电；
- 工业控制：PLC、传感器模块，适配工业温度波动；
- 消费电子：机顶盒、路由器的电源与信号电路。
七、选型与使用注意事项
- 电压降额：实际工作电压≤35V（避免浪涌损坏）；
- 温度匹配：工作环境需在-55℃~+125℃内，超温换NP0介质；
- 精度升级：需±5%精度可选同系列105J型号；
- 焊接规范：回流焊峰值≤260℃（3秒内），避免多次焊接；
- 存储条件：开封前存于-40℃~+60℃、湿度<60%环境，开封后1个月内用完。
该型号凭借稳定性能、标准封装与可靠品牌，是1μF/50V电容的高性价比选择。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
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.
