KM1V221M0812是容强电子(ROQANG)推出的一款中低压径向引线直插铝电解电容,针对体积紧凑、纹波抑制稳定的电子设备设计,核心平衡了电气性能、可靠性与成本控制,适用于工业控制、消费电子、车载及通信等多领域。
该电容以“小体积适配紧凑空间+中低压场景稳定工作”为核心目标,针对中小功率电源系统的滤波、耦合需求优化参数:既避免过高性能冗余导致成本上升,又通过宽温区、高温寿命验证确保工业级可靠性,是替代传统大体积电容的高性价比选择。
标称容值220μF(标识“221”对应22×10¹μF),精度±20%,满足一般滤波、耦合电路的容值需求——对于开关电源输出滤波,容值偏差在±20%范围内不会影响输出电压稳定性,无需额外校准,降低系统设计复杂度。
额定电压35V,比常见的12V、24V直流电源系统高出11V~23V,预留充足电压裕量:可有效应对电源波动、瞬态过压等情况,避免电容因过压击穿损坏,提升系统抗干扰能力。
高频纹波电流参数为270mA@120kHz,120kHz是开关电源(如反激式电源)的典型工作频率,直接决定电容的纹波抑制能力:对于输出电流1A2A的中小功率电源,输出滤波电容的纹波电流需求通常在200mA300mA,270mA的耐受值刚好匹配,可有效降低输出纹波电压,提升电源品质。
工作寿命标称2000hrs@105℃,符合铝电解电容行业标准测试条件(高温连续工作验证)。实际应用中,若设备工作温度为85℃(工业设备常见环境),寿命可延长至约8000hrs(铝电解电容寿命随温度每降低10℃翻倍),满足多数工业设备5年以上使用寿命要求。
采用径向引线直插封装,引脚间距3.5mm,符合PCB标准插件焊盘设计,焊接工艺兼容性强(手工焊、波峰焊均可),无需特殊治具即可批量生产。
电容体直径8mm,长度12mm(不含引脚),属于小体积铝电解电容范畴:相比同容值同电压的10mm直径电容,体积缩小约36%,可适配空间紧凑的设备(如小型车载充电器、路由器电源模块)。
引脚采用镀锡铜材质,抗氧化性强,焊接时不易出现虚焊、假焊;引脚长度经优化,便于PCB插入与固定,降低组装难度。
工作温度覆盖**-40℃~+105℃**,满足极端环境需求:
产品通过以下标准验证:
KM1V221M0812的参数特性适配多场景:
KM1V221M0812直插铝电解电容凭借小体积、宽温区、中低压裕量及匹配的纹波电流能力,成为工业与消费电子领域的高性价比选择,可有效满足中小功率电源系统的滤波需求,同时降低系统设计与成本压力。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
