CA55-D035K476TE150是湘怡中元电子(湘江品牌)推出的高性能钽电解电容器,属于CA55系列核心产品线。型号命名遵循行业通用规则:
该型号聚焦宽温、低漏电流、紧凑封装三大核心优势,适配多类对可靠性要求苛刻的场景。
标称容值47μF,精度±10%,满足大多数滤波、储能电路的容值需求——无需额外并联冗余电容即可保证电路稳定性,尤其适合对容值一致性要求较高的精密电路。
额定直流电压35V,工作电压建议不超过31.5V(额定值的90%),避免过压失效。其电压耐受能力适配中低压电源系统(如12V、24V电源的二次滤波)。
钽电容天然具备低漏电流优势,该型号漏电流通常≤0.01CV μA(C为容值、V为电压),即≤16.45μA——适合精密模拟电路、医疗设备电源等对漏电流敏感的场景,可有效减少电路功耗与信号干扰。
相比铝电解电容,钽电容的等效串联电阻(ESR)更低(典型值≤100mΩ),频率特性更优:在10kHz~100kHz频段仍能保持稳定的滤波效果,适配中高频信号处理(如通信设备射频模块)。
该型号支持**-55℃~+125℃宽温工作范围**,覆盖工业、汽车等领域的极端温度场景:
采用CASE-D-7343标准封装,属于径向引线封装(部分规格为贴片式,需查阅 datasheet 确认),物理尺寸紧凑(参考尺寸约7.3mm×4.3mm×2.5mm),适合高密度PCB布局;封装材料符合无铅RoHS标准,支持回流焊(峰值温度260℃)、波峰焊等常规焊接工艺,兼容性良好。
需注意:钽电容为极性器件,焊接时需严格匹配正负极,避免反向电压导致失效。
基于宽温、低漏电流、紧凑封装等特性,该型号广泛应用于:
湘怡中元(湘江)是国内钽电容领域龙头企业,具备20余年研发生产经验,CA55系列经过严格可靠性测试(温度循环、湿热老化、振动冲击),符合国军标GJB或行业标准,产品一致性好,可替代进口同类型号(如AVX、Kemet对应规格),性价比优势明显。
综上,CA55-D035K476TE150是一款兼顾性能与可靠性的钽电容,适合对温宽、漏电流、体积有严格要求的中高端电子设备。
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.
