FNR3012S1R0NT 产品概述
一、产品简介
FNR3012S1R0NT 是长江微电（cjiang）推出的一款功率型磁胶屏蔽贴片电感，标称电感量 1.0 μH，公差 ±30%，额定电流 2.7 A，饱和电流（Isat）2.8 A，直流电阻（DCR）52 mΩ。封装为 SMD，外形尺寸约 3.0 × 3.0 mm，适合空间受限且需中高电流的开关电源和功率滤波应用。
二、主要性能与特点
- 高电流承载：额定电流 2.7 A，饱和电流 2.8 A，可满足中高电流场合的瞬态与稳态需求。
- 低 DCR：52 mΩ 的直流电阻有利于降低导通损耗，提高整体转换效率。
- 屏蔽结构：磁胶屏蔽设计减小磁通外泄，便于在密集布板环境中应用，降低对周边电路的干扰。
- 紧凑封装：3×3 mm SMD 结构，利于高密度贴装与自动化生产。
- 宽容差选项：±30% 公差适用于对精度要求不严格但更注重成本与电流能力的电源设计。
三、典型应用场景
- 手机、平板等便携终端的 DC-DC 降压转换器（钳位、同步整流等）。
- LED 驱动与背光电源。
- 工控、通信设备的电源滤波与电磁兼容（EMC）处理。
- 电池供电系统与电源管理模块（PMIC）中的储能与滤波元件。
四、使用与选型建议
- 电流余量：虽然 Isat 为 2.8 A，但建议长期工作电流留有裕量（≤ 额定电流 2.7 A）以避免磁芯饱和和过热。
- 损耗评估：设计时应综合考虑 DCR 带来的 I²R 损耗，必要时评估温升与散热条件。
- 布局优化：尽量缩短与开关管、二极管或电感输入/输出之间的回流路径，设置合适的地平面，避免敏感信号线靠近电感端口以减少噪声耦合。
- 焊接工艺：按制造商建议的回流曲线进行焊接，避免过高峰值温度和多次回流引起性能退化。
- 验证测试：在目标应用的典型工作点下验证电感的温升、效率和可能的 EMI 行为，确保满足系统要求。
五、采购与资料
- 品牌：cjiang（长江微电）。型号：FNR3012S1R0NT。封装：SMD，3×3 mm。
- 建议在样片评估阶段索取完整数据手册，确认拓扑下的电流-磁饱和曲线、频率响应和可靠性测试数据，以便完成最终选型与量产验证。
总结：FNR3012S1R0NT 以其紧凑尺寸、较高电流能力和屏蔽结构，适合在空间受限而又需较好功率处理能力的开关电源和滤波场合使用。选型时请关注工作电流余量、DCR 带来的功耗以及具体工艺资料以保证长期可靠性。

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.
