TMPC0402HP-3R3MG-Z02功率电感产品概述
一、产品定位与核心价值
TMPC0402HP-3R3MG-Z02是台庆（TAI-TECH）推出的小型化贴片功率电感，专为高密度、中等功率电子电路设计，核心优势在于体积紧凑与性能平衡——在4.5×4.1mm的小封装内，实现了3.3μH电感值、3A额定电流、4A饱和电流的稳定输出，同时低DCR（69mΩ）降低功耗与发热，适配多种便携式及工业级电源场景。
二、关键电气性能参数解析
2.1 电感值与精度
电感标称3.3μH，精度±20%，覆盖电源滤波、储能电路的常规需求（如DC-DC降压电路输出滤波）。精度范围满足多数民用/工业级应用误差要求，无需额外校准即可稳定工作。
2.2 电流能力（额定电流+饱和电流）
- 额定电流（3A）：额定温度下可持续工作的最大电流，此时电感值下降≤10%（行业常规），适配持续输出3A以下的电源模块；
- 饱和电流（4A）：磁芯未明显饱和时的峰值电流（电感值下降≤30%），可应对负载突变等瞬态峰值，避免磁饱和导致电感失效，提升电路可靠性。
2.3 直流电阻（DCR）
DCR仅69mΩ，属于同体积电感低阻水平。低DCR减少电流功耗（P=I²×R），降低发热，尤其适合对效率敏感的场景（如移动电源、笔记本电池管理）。
三、机械与封装特性
- 封装类型：SMD贴片封装，适配自动化贴装，提高生产效率；
- 尺寸规格：4.5×4.1mm（长×宽），厚度符合行业常规（约2mm），适配空间紧凑设备（如智能手机、智能手表电源模块）；
- 环保合规：符合RoHS、REACH指令，无铅无卤，适配全球市场。
四、典型应用场景
TMPC0402HP-3R3MG-Z02性能匹配多种中等功率电路，核心应用包括：
- DC-DC转换器：笔记本/平板电脑降压电路（5V→3.3V）；
- 移动电源：10000mAh及以下容量输出滤波电感；
- 车载电子：行车记录仪、车载充电器电源模块；
- 智能家居：智能音箱、开关电源管理电路；
- 工业控制：小型PLC、传感器模块电源滤波。
五、品牌与可靠性保障
台庆（TAI-TECH）作为专业电感制造商，产品经严格可靠性测试：
- 温度循环（-40℃~+125℃，1000次）；
- 振动测试（符合IEC 60068-2-6）；
- 湿度测试（85℃/85%RH，1000小时）； 批量供货稳定，一致性好，适合量产项目。
六、选型与使用注意事项
- 电流限制：持续电流≤3A，峰值电流≤4A（避免磁饱和）；
- 焊盘匹配：按官方 datasheet 设计焊盘，确保焊接可靠性；
- 散热设计：高电流工作时，需增加PCB铜箔面积辅助散热；
- 环境温度：建议工作温度≤+105℃（考虑额定电流下温升）。
该产品兼顾体积、性能与成本，是中等功率电路中功率电感选型的高性价比方案。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
