DFP252012TF-4R7M是台庆电子(TAI-TECH)推出的贴片式功率电感,专为中小功率电子设备的电源管理、信号滤波场景设计。产品型号中:
标称电感值4.7μH,精度±20%(实际范围3.76μH~5.64μH)。该精度覆盖常规功率电路的设计余量,无需额外补偿电路,降低系统设计难度。
230mΩ(毫欧),直接影响功耗(P=I²×DCR)。以1.5A额定电流计算,功耗约0.52W,在小尺寸电感中属于合理范围,有效控制发热。
贴片式(SMD)封装,兼容常规回流焊工艺;工作温度范围-40℃~+125℃,适应工业及消费电子环境。
DFP252012TF-4R7M的小尺寸、中等电流能力,适配以下场景:
2.5×2.0×1.2mm封装比常规功率电感体积缩小约30%,适配高密度PCB设计,降低设备整体尺寸。
台庆自动化生产工艺保证参数一致性,批量应用时减少电路调试工作量。
1.5A额定电流+230mΩ DCR,兼顾电流能力与功耗控制,避免发热导致的性能衰减。
贴片封装兼容常规SMT生产线,无需特殊焊接设备,降低制造成本。
该产品以小尺寸、稳定性能适配中小功率场景,是便携式设备、汽车电子等领域的实用选择。

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.
