CS1E221M-CRF10 贴片型铝电解电容产品概述

一、核心参数总览

CS1E221M-CRF10是一款专为低压通用电路设计的贴片型铝电解电容,核心参数覆盖电容选型的关键维度,具体如下:

参数项 规格详情 标称容值 220μF 容值精度 ±20% 额定直流电压 25V(VR) 纹波电流能力 183mA @ 120Hz(20℃环境) 封装类型 SMD贴片式 电容体尺寸 直径8mm × 长度10.5mm(D8×L10.5) 工作温度范围 -40℃ ~ +105℃ 额定寿命 2000小时 @ 105℃(额定电压下) 品牌 ROQANG(容强)

二、关键性能指标解析

1. 容值与精度适配

220μF属于中低容量区间,满足大多数通用电路的滤波、耦合需求;±20%的精度是铝电解电容的常规商用级标准,无需高精度校准的场景(如电源滤波、音频耦合)下性价比突出,同时避免因精度要求过高导致的成本上升。

2. 额定电压的安全余量

25V DC额定电压,适配5V、12V等低压电源系统(一般选型需额定电压高于工作电压1.2~1.5倍),留有充足的安全余量,可有效避免电路过压时的电容击穿风险,提升系统稳定性。

3. 纹波电流的实际价值

183mA@120Hz的纹波电流能力是核心性能亮点:
120Hz是市电整流后的主要纹波频率(全波整流后为100Hz,设计中加入20Hz裕量),该参数可满足小功率电源(如手机充电器、小型LED驱动)的滤波需求,有效抑制输出纹波,减少电路噪声对敏感元件的干扰。

三、封装与物理特性

采用SMD贴片封装,电容体尺寸仅D8×L10.5mm,属于小型化贴片铝电解电容,优势显著:

  • 适配高密度PCB设计:如智能手机、平板电脑的电源模块,可与其他贴片元件紧凑布局;
  • 满足小型设备空间限制:智能手环、蓝牙耳机的充电管理模块,或小型智能家电(如加湿器、智能插座)的内部电路;
  • 支持自动化生产:贴片封装便于SMT贴装,提升生产效率,降低人工成本。

四、工作环境与寿命可靠性

1. 宽温范围覆盖全场景

-40℃~+105℃的工作温度,覆盖了绝大多数应用环境:

  • 低温场景:户外电子设备(如智能电表、监控摄像头)冬季低温下正常工作;
  • 高温场景:小型家电内部电路发热(如加湿器)、车载电子(如车载充电器)的低温区应用,无需额外散热设计。

2. 寿命满足长期使用需求

2000小时@105℃的额定寿命(额定电压下),遵循阿伦尼乌斯定律:温度每降低10℃,寿命约延长2倍。例如:

  • 60℃环境下,寿命可达约16000小时;
  • 25℃常温下,寿命可达数年,满足消费电子、工业控制等场景的长期稳定需求。

五、典型应用场景

结合性能参数,CS1E221M-CRF10主要适配以下场景:

  1. 消费电子:智能手机/平板电源滤波、蓝牙耳机充电模块、小型家电(加湿器、智能插座)电源系统;
  2. 工业控制:小型PLC输入输出滤波、传感器模块(温度/压力)电源稳定、小型电机驱动滤波;
  3. 通信设备:小型路由器/交换机电源模块、无线AP辅助电源滤波。

六、品牌与品质保障

该电容由ROQANG(容强)品牌生产,容强专注铝电解电容研发生产多年,产品覆盖通用型、高频低阻型、长寿命型等系列,广泛应用于消费电子、工业、通信领域。

CS1E221M-CRF10遵循IEC 60384等行业标准,出厂前经过电性能测试(容值、ESR、漏电流)和环境测试(温度循环、湿度老化),确保品质稳定可靠,可替代同类进口品牌的通用型贴片铝电解电容。

总结:CS1E221M-CRF10凭借小型化封装、宽温适应性、稳定的纹波电流能力,成为低压通用电路滤波、耦合的高性价比选择,适配多种小型电子设备的需求。

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.

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
