FTW2012FE4R7KT是长江微电(cjiang)推出的0805封装功率电感,核心参数清晰适配小功率应用需求:
这些参数是电路设计选型的核心依据,直接界定了产品的适用场景。
4.7uH的电感值搭配±10%精度,既避免了过高精度的成本冗余,又能有效控制电路性能波动(如DC-DC转换效率、纹波抑制)。对于不需要超精密电感的便携设备、小型通信模块等场景,该精度已足够支撑稳定工作。
360mΩ的直流电阻处于同封装电感的较低水平,能减少电流通过时的功耗(P=I²R),降低电路发热。这对空间紧凑、散热有限的便携设备(如智能手表、蓝牙耳机)尤为重要,可提升续航与可靠性。
0805封装体积小巧,兼容现代电子设备的轻薄化趋势;表面贴装工艺适配自动化生产,提升组装效率,降低制造成本。
FTW2012FE4R7KT的参数特性使其在以下场景表现突出:
0805封装符合行业标准,兼容常规PCB设计与自动化贴装设备,无需额外定制工艺,降低设计门槛。
采用长江微电自研的优质磁芯材料(如铁氧体/合金磁芯),确保电感值在不同温度、电流下的稳定性;绕组采用高导电率铜线,进一步降低DCR。
产品通过RoHS、REACH环保认证,无有害物质残留;工作温度覆盖-40℃~+85℃(部分批次支持+105℃),适配消费级到工业级场景。
长江微电是国内功率电感领域的成熟厂商,拥有多年研发与生产经验。FTW2012FE4R7KT经过严格可靠性测试(温度循环、振动测试),品质稳定可靠,供应能力充足,适合批量生产需求。
综上,FTW2012FE4R7KT是一款针对小型化、低功耗设备设计的高性价比功率电感,凭借稳定精度、低DCR、小体积等特点,能为各类DC-DC转换、滤波电路提供可靠支撑,是便携设备、通信模块等场景的理想选型。
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.
