KNSCHA(科尼盛)149EC920是一款针对低压高频场景优化的固态铝电解电容,以稳定的电气性能、紧凑封装及可靠高温寿命,成为消费电子、汽车电子、工业控制等领域电源滤波与储能的核心元件。
149EC920的参数精准匹配低压电源系统需求,核心指标如下:
149EC920的核心优势集中在高频适配、可靠性与体积优化三个维度: 首先,高频纹波抑制能力强:40mΩ的低ESR大幅降低电容高频发热,2.26A纹波电流可有效滤除开关电源(如DC-DC转换器)的100kHz左右高频纹波,提升电源纯净度,减少后级EMI干扰; 其次,固态电解质提升可靠性:采用导电聚合物固态电解质,避免传统液态电容的漏液、干涸、容值衰减快等问题,105℃下寿命是普通液态电容的2-3倍,适合高温环境; 第三,小体积适配紧凑型设计:6.3mm直径+7.7mm长度的封装,比同容值同电压液态电容体积缩小约30%,满足手机、平板等对尺寸敏感的产品需求。
149EC920的性能特点使其适配多场景低压高频应用:
149EC920采用SMD贴片封装,符合IPC标准引脚设计,支持回流焊工艺,适合自动化批量生产;电容体以耐高温环氧树脂封装,抵御湿度、灰尘侵蚀;引脚镀锡工艺,焊接可靠性高,无虚焊风险。
产品经过严格可靠性测试:105℃下2000小时寿命测试(容值衰减≤20%、ESR上升≤30%)、额定纹波电流老化测试、-55℃~125℃温度循环测试(500次),确保批量一致性。
KNSCHA(科尼盛)是国内电容制造高新技术企业,10余年专注铝电解电容研发,产品覆盖固态、液态、高分子系列,服务国内外知名品牌。
149EC20通过ISO9001、RoHS认证,部分批次满足IATF16949汽车级要求,可提供定制化服务(如特殊引脚长度、容值微调),灵活适配客户设计需求。
总结:KNSCHA 149EC920以低ESR、高纹波承载、小体积、长寿命为核心优势,是低压高频电源系统的理想滤波元件,可有效提升设备供电稳定性与可靠性,适配多领域设计需求。
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.
