FNR4026S2R2MT是长江微电(cjiang)推出的一款磁胶屏蔽SMD功率电感,针对中小功率电源转换场景设计,兼具小体积、低损耗与电磁兼容特性,可满足消费电子、车载、工业等多领域的应用需求。
该电感属于功率电感范畴,型号命名清晰对应核心特性:
作为长江微电的成熟产品线成员,其工艺一致性与可靠性经过批量验证,适合量产化电子设备应用。
电感值为2.2μH,精度±20%,满足一般DC-DC转换、滤波等电路的电感值设计需求(无需超高精度场景时可降低成本)。实际应用中,该精度可覆盖多数中小功率电源的纹波控制要求。
DCR为52mΩ,内阻较低,可减少电流通过时的功率损耗(P=I²R),提升电源转换效率。例如,当工作电流为2A时,损耗仅为0.208W,适合对功耗敏感的移动设备、车载电源等场景。
采用磁胶屏蔽结构,相比非屏蔽电感可显著降低电磁辐射(EMI),符合电磁兼容(EMC)标准,避免对周边敏感电路(如射频模块)造成干扰,适用于对EMI要求严格的车载、通信设备。
SMD(表面贴装)封装,尺寸紧凑(4×4mm级别),可直接通过SMT工艺贴装于PCB,适合自动化生产,节省PCB布局空间,适配小型化电子设备(如手机、智能穿戴)。
长江微电(cjiang)是国内专注于电感研发生产的企业,其产品通过以下可靠性测试验证:
FNR4026S2R2MT的磁胶屏蔽工艺成熟,批量供货一致性好,可作为中小功率电源设计的优选电感之一。
该产品平衡了性能、体积与成本,适合对EMI、功耗有要求的中小功率电源场景,是电子设备电源设计的实用选择。

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.
