Ymin永铭LKMC1101C331MF直插铝电解电容产品概述

一、产品核心定位

LKMC1101C331MF是永铭(Ymin)推出的通用型直插铝电解电容,针对中小功率低压电路的滤波、耦合、去耦核心需求设计,兼顾体积紧凑性、高频性能与长寿命可靠性,适配消费电子、小家电、小型电源等多类场景,是替代传统低寿命电容的高性价比选择。

二、关键参数深度解析

1. 容值与精度

容值为330μF(±20%),覆盖了大多数低压电路的滤波容量需求——既满足电源输出端的大电流纹波抑制,也适配信号耦合场景的容量匹配;±20%的精度符合工业级电容常规标准,能满足多数应用的误差要求,无需额外校准。

2. 额定电压与耐压

额定电压为16V,精准适配12V、5V等低压直流系统(如电池供电设备、LED驱动电源),留有足够安全余量(实际耐压通常高于额定值),避免过压损坏风险,适合低压电路的稳定运行。

3. 纹波电流与高频性能

纹波电流指标为550mA@100kHz,直接反映电容的高频纹波抑制能力——100kHz是开关电源的典型工作频率,550mA的纹波耐受能力可有效过滤开关电源输出端的高频杂波,提升电路输出纯净度与稳定性。

4. ESR与损耗

等效串联电阻(ESR)为210mΩ@100kHz,对于直径仅6.3mm的小体积电容来说,该数值处于中等偏优水平。低ESR意味着电容自身损耗小、发热低,能进一步延长工作寿命,同时提升滤波效率,减少电路热应力。

5. 工作寿命

寿命指标为9000hrs@105℃,远高于普通105℃电容的5000hrs标准,说明电容在高温环境下(如设备内部散热空间有限、环境温度较高的场景)仍能稳定工作,可靠性更有保障,降低设备维护成本。

三、封装与物理特性

1. 封装形式

采用径向引线直插封装,引脚从电容体两端垂直引出,适合传统插件焊接工艺,对PCB设计兼容性好,无需特殊贴装设备,降低生产门槛,适配中小批量生产需求。

2. 尺寸规格

  • 脚间距:2.5mm(标准直插间距,适配多数PCB焊盘设计,无需特殊调整)
  • 电容体直径:6.3mm(小直径设计,节省PCB空间)
  • 电容体长度:11mm(整体高度低,适合紧凑型设备内部布局,如小型电源模块、小家电控制板)

小体积大容量的设计是本产品核心优势之一,尤其适合空间受限的场景。

3. 引脚设计

直插引脚采用镀锡工艺,焊接牢固,抗振动性能优于贴片电容,适合对振动有一定要求的小家电(如搅拌机、吸尘器)或车载辅助电路,减少引脚虚焊风险。

四、典型应用场景

结合参数与封装特性,LKMC1101C331MF主要适配以下场景:

  1. 中小功率开关电源:如手机充电器、LED驱动电源的输出滤波,抑制高频纹波;
  2. 小家电控制板:电饭煲、加湿器、电热水壶的电源滤波/耦合,适配小体积设计;
  3. 低压直流系统:12V电池供电设备(如户外照明、小型储能)的去耦电路;
  4. 工业控制辅助电路:PLC、传感器模块的低压滤波,长寿命满足工业环境需求。

五、选型优势总结

  1. 小体积高容量:6.3mm直径实现330μF/16V,空间利用率远高于同类产品;
  2. 高频性能适配:550mA@100kHz纹波电流,精准匹配开关电源需求,提升输出稳定性;
  3. 长寿命可靠:9000hrs@105℃,高温环境下稳定性优于同类电容,降低设备故障率;
  4. 性价比突出:永铭作为国内知名电容品牌,性能稳定且成本可控,适合批量应用;
  5. 工艺成熟:采用优质电解液与阳极箔,ESR长期稳定,减少电容老化带来的性能衰减。

本产品凭借平衡的性能与成本优势,成为低压电路滤波/耦合场景的实用选择,能满足多数中小功率设备的可靠性需求。

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.
