CS1E331M-CRF10 产品概述
一、产品简介
CS1E331M-CRF10 为 ST（先科）推出的一款贴片型铝电解电容，额定容量为 330µF，公差 ±20%，额定电压 25V。电容体尺寸为直径 8mm × 长度 10.5mm（D8×L10.5mm），适用于高密度贴片布局的电源滤波和去耦场合。设计用于表面贴装工艺，兼顾体积小、容量大与良好可靠性。
二、主要技术参数
- 容值：330µF
- 精度：±20%
- 额定电压：25V
- 尺寸：φ8mm × L10.5mm（SMD）
- 工作温度：-40℃ ～ +105℃
- 工作寿命：2000小时 @ 105℃
- 封装：SMD（贴片）
- 品牌：ST（先科）
注：具体等效串联电阻（ESR）、漏电流等电性能参数请参照厂方完整规格书或样品测试数据。
三、关键特性与优势
- 高容值/小体积：在仅 8×10.5mm 体积下实现 330µF 容量，适合空间受限但需大容量滤波的应用。
- 宽温度范围：-40℃ 至 +105℃，可满足一般工业和消费类电子的温度要求。
- 长寿命设计：2000小时 @105℃ 的寿命等级，适用于中长期稳定运行的电源线路。
- 贴片工艺友好：SMD 封装适合自动贴装与回流焊，提高生产效率与可靠性。
四、典型应用场景
- 开关电源输入/输出滤波与储能
- DC-DC 转换器及稳压模块的去耦和缓冲
- 工业控制、通讯设备和消费电子的主/辅助电源
- 对体积与重量敏感的便携设备电源方案
五、封装与装配建议
- 推荐采用标准 SMD 自动贴装和回流焊工艺，装配后应避免机械应力集中在电容体上。
- 回流焊曲线请参考厂方建议，避免多次高温循环影响寿命。
- 在设计 PCB 时，注意露铜面积、焊盘尺寸与散热路径，以平衡焊接可靠性与热应力。推荐在电容周围留有适当的间距，便于热量释放与清洗。
六、可靠性与选型注意事项
- 该系列在高温高压下仍会随时间衰减电容容量，建议按实际使用温度与期望寿命预留裕量。
- 对低 ESR、高脉冲寿命有严格要求的场合，应确认具体 ESR 与脉冲失真指标，必要时做实际样片评估。
- 选型时考虑电压裕量（通常建议额定电压高于实际工作电压）及环境应力（振动、冲击、湿热）。
七、采购与识别
- 型号：CS1E331M-CRF10，品牌 ST（先科），封装 SMD 8×10.5mm。
- 订购时请核实批次与完整规格书，必要时索取样片进行电气与热循环验证。
- 如需替代或配套产品，可提供同系列不同电压/容量选项以便统一平台设计。
如需我为您提供该型号的完整规格书（含 ESR、漏电流、寿命曲线与回流焊曲线）或进行与现有电路的匹配评估，可告知应用工况与电路参数，我将协助选型与布局建议。

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.
