TMPC1205HP-3R3MG-D 产品概述
一、产品概述
TMPC1205HP-3R3MG-D 为 TAI-TECH（台庆）推出的一款高电流贴片功率电感，额定电感值为 3.3 µH（公差 ±20%），直流电阻（DCR）仅 6.8 mΩ，额定电流 15 A，饱和电流（Isat）可达 32 A。该器件采用 SMD 封装，适合高密度板级电源设计，用于开关电源滤波、储能与瞬态电流支撑等关键电源环节。
二、主要参数
- 品牌：TAI-TECH（台庆）
- 型号：TMPC1205HP-3R3MG-D
- 电感值：3.3 µH ±20%
- 额定电流：15 A（连续工作电流）
- 饱和电流（Isat）：32 A（磁芯进入饱和前的参考电流）
- 直流电阻（DCR）：6.8 mΩ
- 封装形式：SMD（贴片）
三、性能特点
- 低直流电阻：6.8 mΩ 有效降低铜损和功耗，提高整体转换效率。
- 高电流承载能力：15 A 额定电流结合 32 A 的饱和电流裕量，能应对较大的瞬态电流和冲击负载。
- 稳定的电感特性：在常见工作点下保持良好滤波与储能效果，适配多种开关频率范围。
- SMD 封装：利于自动化贴装与回流焊工艺，便于高密度布板和可靠性要求高的产品设计。
四、典型应用场景
- DC-DC 降压（Buck）转换器输出滤波或储能电感
- 高电流电源模块与电源管理单元（PMU）
- 服务器、通信设备与电信基站电源滤波
- 汽车电子供电系统（符合电源抗扰与冲击要求的设计）
- LED 驱动、电池管理与便携式大电流负载电源
五、设计与布局建议
- 布局靠近开关器件与电感输入/输出端，尽量缩短高频回路环路面积以减少 EMI。
- 采用多过孔（vias）并联增强散热，从而提高电感的持续载流能力和热稳定性。
- 在额定电流附近工作时建议留有安全裕量（通常 20%~30% 的电流余量），以避免长期温升和磁芯接近饱和。
- 与电容、MOSFET 等元件配合时，注意环路阻抗匹配与滤波效率优化，必要时做电路仿真或测试验证。
六、注意事项与可靠性
- 焊接工艺应采用推荐的回流曲线，避免超温或长时间高温导致封装与磁芯特性变化。
- 存储与搬运时建议防潮包装与避免机械冲击。
- 在高温或高湿环境下使用时，应考虑温升对直流电阻与电感值的影响，必要时进行温度循环和老化测试验证。
- 选型时需根据实际工作频率、纹波电流与允许温升综合评估，确保电感在目标工况下既不过热也不过饱和。
TMPC1205HP-3R3MG-D 以其低 DCR、高电流承载能力与贴片封装优势，适合对效率和空间有较高要求的中高功率电源设计，是降低损耗、提升系统稳定性的可靠选择。若需样品、详细封装尺寸或频率特性曲线，请联系供应商或查阅产品数据手册。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
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.
