TMPC0503H-3R3MG-D是台庆电子(TAI-TECH)针对中大功率电源系统优化设计的贴片式功率电感,凭借高饱和电流、低直流损耗、紧凑封装等核心优势,广泛适配消费电子、车载、通信等领域的电源电路需求。
该电感隶属于台庆电子(TAI-TECH)功率电感产品线,型号中“TMPC”为品牌编码,“0503”对应封装尺寸逻辑,“3R3”表示电感值3.3μH,“MG-D”为工艺与版本标识,属于绕线式功率电感范畴。
采用2220贴片封装(英制尺寸,对应公制约5.6mm×5.0mm×3.0mm,具体以官方 datasheet 为准),符合表面贴装(SMT)工艺要求,适配自动化生产线,同时兼顾体积紧凑与功率密度。
8A饱和电流远高于额定工作电流,可有效应对电路瞬态冲击(如电源启动瞬间、负载突变)——避免电感饱和导致的电感值骤降、输出电压波动,显著提升电源系统稳定性。
32mΩ的DCR大幅降低铜损(公式:(P=I^2×R)):在4.3A额定电流下,铜损仅约0.59W,减少散热需求的同时,将电源转换效率提升2%~3%(对比同电感值、高DCR产品)。
±20%的电感精度覆盖多数功率电路设计裕量,无需额外校准,且批量生产一致性优异,降低电路调试难度。
2220封装体积小巧,在有限PCB空间内实现4.3A/3.3μH的功率密度,适配便携式设备(如笔记本)、高密度电源模块等对空间敏感的场景。
该电感的性能特点使其适配多领域中大功率电源电路:
采用绕线+环氧树脂封装:绕线结构保证电感性能,环氧树脂固定绕线并提升抗振动能力;引脚设计适配标准回流焊,焊接良率≥99%。
封装材料具备低吸湿性,存储于湿度≤60%环境下,引脚氧化风险低,使用寿命≥50000小时。
TMPC0503H-3R3MG-D凭借平衡的性能与可靠性,成为中大功率电源电路的高性价比选择,可覆盖多领域终端产品的电源设计需求。

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.
