CS1A102M-CRF10 产品概述

一、主要参数

CS1A102M-CRF10 为贴片型铝电解电容(品牌:ROQANG 容强),主要电气与尺寸参数如下:额定容量 1000µF,容量公差 ±20%,额定电压 10V,纹波电流 280mA(标注于 120Hz),电容体直径 D=8mm,长度 L=10.5mm,工作温度范围 -40℃~+105℃,在 105℃ 下寿命 2000 小时,封装形式 SMD,型号标识 D8×L10.5mm。

二、性能与特点

  • 高容量/小体积:1000µF 在直径 8mm、长度 10.5mm 的小封装中实现,适合空间受限的电源去耦和滤波场合。
  • 中等纹波能力:标称 280mA@120Hz,满足中低功率开关电源与整流滤波的纹波处理需求。
  • 宽温度与较短高温寿命:可工作至 105℃,适合商规/工业级产品,但在高温下寿命有明显限制(2000hrs@105℃)。

三、典型电气计算示例

仅考虑电容的容抗对交流纹波的影响(不含 ESR),在 120Hz 条件下,若以标称纹波电流 0.28A(RMS)计算:

  • 对应电压有效值 V_rms = I_rms / (2πfC) ≈ 0.28 / (2π·120·1000µF) ≈ 0.37V;
  • 若假设为正弦分量,则峰峰值约 V_pp ≈ 1.05V。
    实际电路中需加上 ESR 引起的压降(ΔV_ESR = I_rms × ESR),因此最终纹波电压由容抗与 ESR 共贡献,设计时应参考厂家给出的 ESR 或通过实际测量判定是否满足系统要求。

四、可靠性与寿命建议

  • 高温寿命:标称 2000hrs@105℃;按常用经验法则(温度每降 10℃ 寿命近似翻倍),在 85℃ 时寿命估算可达约 8000 小时(仅作估算,需实验验证)。
  • 降额使用:为延长寿命,建议在高温或连续高纹波工况下对额定电压进行降额(常见做法将工作电压控制在额定值的 60%~80% 范围内,即建议在 6~8V 区间使用),并保证良好散热。

五、应用场景与布局建议

  • 典型应用:SMPS 输出滤波、电池供电系统去耦、整流桥后滤波、DC-DC 转换器输入/输出补偿等。
  • PCB 布局:建议将电容尽量靠近被滤波器件(整流桥或稳压器)引脚放置,缩短回流路径和等效串联电感;铺设足够的焊盘尺寸并考虑热缓冲区以利回流焊;安装时注意极性标识并避免倒装,排气孔/安全阀应尽量朝向上方或无障碍方向。

六、注意事项与订购信息

  • 禁止反向电压及超额定电压使用,避免长时间在高温高纹波状态下工作。
  • 回流焊与返修请遵循厂商推荐的焊接曲线和温度限值,避免过高峰值温度和长时间暴露。
  • 订购时可按型号 CS1A102M-CRF10 向 ROQANG 查询包装形式(卷带数量)、ESR/等效串联电感的典型值以及完整的回流焊规范,以便系统级验证与可靠性评估。

以上为 CS1A102M-CRF10 的技术概述与应用建议,如需器件的 ESR、阻抗频率特性曲线或回流焊曲线等详细数据,可联系供应商获取完整数据手册并进行实际样片测试验证。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
