KM1V471M1016 直插铝电解电容产品概述
一、产品基本定位与应用场景
KM1V471M1016是一款通用型径向直插铝电解电容，由容强（ROQANG）品牌出品，专为电子电路中的滤波、耦合、旁路等核心功能设计，覆盖多领域实用场景：
- 工业控制：小型PLC、伺服驱动器的电源滤波；
- 消费电子：LED驱动电源、小家电控制板的电压稳定；
- 通信设备：路由器、交换机的低纹波滤波；
- 电源模块：12V/24V开关电源的输出滤波。
其参数适配中低功率电路，既满足常规性能需求，又通过宽温与稳定寿命适应不同环境下的长期工作。
二、核心电气参数详解
该电容关键性能参数明确，可直接匹配电路设计：
- 容值与精度：标称470μF，精度±20%——符合铝电解电容工业级常规精度，无需高精度场景下平衡成本与性能；
- 额定电压：直流35V——电路实际工作电压（含纹波峰值）需低于此值，建议留10%-20%余量（如≤31.5V）以保障可靠性；
- 纹波电流能力：460mA@120kHz——120kHz是开关电源典型频率，此参数表示电容在该频率下可承受的最大纹波电流，若负载纹波过高，需并联多只电容；
- 温度与寿命：工作范围-40℃~+105℃，额定寿命2000hrs@105℃——在105℃下连续工作2000小时后，容值变化、损耗角仍符合标准；实际温度降低时寿命指数级延长（如60℃时可达约10000hrs）。
三、机械结构与封装特性
采用径向引线直插封装，机械尺寸紧凑适配PCB设计：
- 电容体尺寸：直径D10mm，长度L16mm（不含引脚），体积小巧，适合空间受限的PCB布局；
- 引脚间距：5mm——符合常规插件PCB的钻孔规范，无需特殊设计；
- 封装类型：径向引线（引脚从电容体两端引出），安装时需注意极性（铝电解电容极性明确，需对应PCB正负极焊盘）。
四、可靠性与环境适应性
该电容可靠性设计针对多场景优化：
- 宽温适应性：-40℃~+105℃覆盖户外低温、工业高温等极端环境，满足恶劣工况需求；
- 纹波耐受能力：460mA@120kHz可有效抑制开关电源电压波动，减少电磁干扰；
- 寿命稳定性：经过品牌内部老化测试验证，2000hrs@105℃的额定寿命满足中短期应用（长期高可靠场景可升级同品牌长寿命系列）。
五、品牌与选型参考
容强（ROQANG）作为国内铝电解电容专业品牌，产品以“高性价比+稳定性能”为核心，KM1V471M1016是其通用系列典型型号。选型需注意：
- 电压匹配：电路实际电压（含纹波峰值）≤35V，避免过压损坏；
- 纹波匹配：若纹波电流超460mA@120kHz，需并联2-3只电容；
- 尺寸匹配：PCB预留10mm×16mm电容体空间，引脚间距5mm；
- 环境匹配：105℃高温下工作时间≤2000hrs，否则需升级长寿命型号。
该电容综合性能适配多数通用电路需求，是工业与消费电子领域的经济实用选择。

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.
