FNR3015S1R0MT — 1µH 磁胶屏蔽功率电感 产品概述

一、产品概述

FNR3015S1R0MT 是长江微电(cjiang)推出的一款小型表面贴装功率电感,标称电感值 1µH,精度 ±20%,封装尺寸 3.0 × 3.0mm(SMD)。采用磁胶屏蔽结构,适合高密度布板和自动化贴装生产,针对中低功率开关电源与点负载电源设计,兼顾较高的直流电流承载能力与良好的磁场抑制性能。

二、主要规格

  • 电感值:1µH ±20%
  • 额定电流(Ir):2.5A
  • 饱和电流(Isat):2.8A
  • 直流电阻(DCR):约 39mΩ
  • 类型:磁胶屏蔽电感(屏蔽型功率电感)
  • 封装:SMD,尺寸 3×3mm
  • 品牌/型号:cjiang(长江微电) / FNR3015S1R0MT

三、性能特点

  • 小体积高电流:3×3mm 小尺寸满足高密度布局要求,额定电流 2.5A,饱和电流 2.8A,适合中高电流点负载。
  • 低损耗:DCR 约 39mΩ,降低铜损,提高转换效率(在额定电流 2.5A 时,理论 I^2·R 损耗约 0.244W,可据此评估温升与散热需求)。
  • 良好屏蔽性:磁胶屏蔽结构减少磁通外泄,降低对周边敏感器件的干扰,利于 EMI 控制。
  • 贴片化封装:支持 Tap & Reel 卷带供料,便于 SMT 自动焊接与大批量生产。

四、典型应用

  • 同步整流降压(buck)/ 升压(boost)开关电源与点负载模块。
  • 手机、平板、电源管理、通信设备、LED 驱动及工业控制中要求中等电流的电源滤波与能量储存场合。
  • 对 EMI 有要求且空间受限的电路板设计。

五、PCB 布线建议与选型注意

  • 输入/输出电容应靠近电感焊盘布置,减小回流回路面积以降低 EMI。
  • 考虑 DC 偏置下电感量下降,实际电路中应留有余量;若对电感精度要求高,选择更低容差器件或补偿设计。
  • 依据 DCR 估算损耗并做好散热与热阻管理;长期超额电流会导致发热与性能退化,应按额定电流并做好裕量。
  • 频率、温度特性及退磁/耐压等详细参数请参照厂方完整 datasheet。

六、包装与可靠性提示

FNR3015S1R0MT 适合卷带自动贴片生产,建议在常见工业温度范围及推荐回流焊工艺条件下使用。出货前应关注批次一致性与焊接参数。对于关键应用(高温、长寿命或极限电流场合),建议进行样机评估与实际寿命试验。

如需完整电气特性曲线、频率响应、温度特性或贴片尺寸图纸,请索取长江微电官方规格书(datasheet)以获得准确信息。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
