KCXD1002G100MF是永铭(Ymin)品牌推出的一款径向直插铝电解电容,针对中高压电路的滤波、耦合及储能需求设计,以紧凑尺寸实现稳定性能,广泛适配工业控制、家电、电源等领域的实际应用场景。
该电容的核心技术参数清晰明确,可直接匹配电路设计需求:
中高压稳定耐受
400V DC额定耐压覆盖多数开关电源、LED驱动等高压电路的母线电压需求,避免因耐压不足导致的电容损坏;同时,内部电解液配方优化,可有效抑制高压下的漏电流,提升长期稳定性。
紧凑尺寸适配小型化
8mm直径×10mm长度的电容体,在同耐压(400V)、同容值(10μF)级别中属于体积较小的型号,可显著节省PCB板空间,适配手持设备、小型家电等对尺寸敏感的产品设计。
引线可靠性强
径向引线采用优质镀锡铜,直径约0.6mm,长度约15mm(不含电容体),兼具强度与柔韧性:焊接时不易氧化,可通过常规波峰焊、手工焊实现可靠连接;引脚耐弯折,便于插件加工及后期调试。
宽温性能稳定
-40℃至+105℃的工作温度范围,可适应不同环境(如北方冬季户外设备、南方夏季工业现场),在极端温度下容值衰减缓慢,避免因温度变化导致电路性能波动。
开关电源滤波
作为电源输出端、高压母线的滤波电容,抑制电压纹波(典型纹波抑制比可满足多数电源设计要求),提升电源输出稳定性,适配PC电源、工业电源等。
LED驱动电源
用于高压LED驱动电路的滤波与储能,支持LED灯具(如路灯、隧道灯)的稳定点亮,避免因电压波动导致的LED闪烁或损坏。
家电控制板
适配空调、洗衣机、冰箱等家电的控制电路,用于电源滤波、耦合,保障MCU、继电器等核心器件的正常工作。
工业控制模块
PLC、变频器、伺服驱动器等工业设备的辅助电源电路,满足高压环境下的滤波需求,适配工业现场的复杂工况。
封装结构
圆柱形电容体,两端引出两根径向引脚,引脚间距约5mm(符合常规PCB插件标准,可兼容多数电路板设计)。
极性标识
电容体侧面印有负极标识(通常为白色或黑色条纹),需严格按照标识连接正负极——铝电解电容为极性电容,反向连接会导致漏电流急剧增大、发热甚至爆炸。
安装间隙
电容体与PCB板之间建议预留1~2mm间隙,避免安装过紧导致电容体变形,影响内部电解液及铝箔的性能。
极性确认
焊接前务必核对电容体的负极标识,正负极接反会直接损坏电容,甚至引发电路故障。
电压降额
实际工作电压不得超过额定400V DC;若电路存在尖峰电压(如开关电源的瞬态电压),建议降额20%以上使用(即实际工作电压≤320V DC),延长电容寿命。
焊接要求
焊接温度控制在260℃以下,焊接时间不超过3秒;避免使用过高温度或过长时间焊接,防止电解液汽化、电容体膨胀。
储存条件
未使用的电容应储存在温度-10℃~+40℃、相对湿度≤75%的环境中,避免阳光直射、腐蚀性气体(如硫化氢)接触,储存周期建议不超过1年。
KCXD1002G100MF凭借紧凑尺寸、稳定耐高压性能与宽温适应能力,成为中高压电路滤波应用的高性价比选择,适配多领域的实际需求,是永铭品牌的成熟电解电容产品之一。
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.
