FNR3012S330MT 磁胶屏蔽功率电感产品概述
一、产品基本定位
FNR3012S330MT是长江微电（cjiang）推出的表面贴装磁胶屏蔽功率电感，专为小型化、低功耗电子设备的电源管理及信号滤波场景设计。该产品采用SMD 3×3mm紧凑型封装，兼具高电感值密度与低电磁干扰（EMI）特性，是消费电子、IoT终端等领域的理想电感方案。
二、核心电气参数解析
1. 电感特性核心参数
- 电感值：33μH，精度±20%——满足大多数中低功率DC-DC转换器、滤波电路的电感量需求，±20%的精度覆盖批量生产一致性要求，无需额外校准；
- 额定电流（Irms）：500mA——指电感持续工作时温度上升不超过允许范围（通常≤40℃）的最大电流，适配小型电源模块的稳定输出；
- 饱和电流（Isat）：460mA——定义为电感值下降至初始值80%时的电流，是避免磁饱和的关键指标。该参数接近额定电流，可有效防止电感性能突变，提升电路可靠性。
2. 损耗与效率参数
- 直流电阻（DCR）：1.138Ω——DCR直接影响电感功耗（P=I²×DCR），低阻值可减少电源转换损耗，提升整体电路效率。
三、封装与物理特性
- 封装规格：SMD 3×3×1.2mm（行业常规3012封装）——超小型化设计，可节省30%以上PCB空间，适配智能穿戴、微型IoT节点等尺寸严苛的设备；
- 磁胶屏蔽结构：采用磁胶包裹线圈，漏磁比非屏蔽电感减少60%以上，有效抑制EMI干扰，避免对射频模块等敏感电路造成影响；
- 焊接兼容性：支持回流焊、波峰焊等自动化工艺，引脚符合IPC标准，焊接可靠性高，适合大规模量产。
四、典型应用场景
结合参数特性，FNR3012S330MT主要应用于：
- 小型电源管理：手机、平板的DC-DC降压转换器（5V转3.3V/1.8V）、升压电路（LED背光驱动）；
- 可穿戴设备：智能手环、手表的充电电路、低功耗传感器供电；
- IoT终端：智能门锁、温湿度传感器节点的电源滤波与稳压；
- LED驱动：小功率LED灯串（手机闪光灯、智能台灯辅助照明）的恒流驱动；
- 汽车电子辅助：车载胎压监测、氛围灯等小型传感器的电源模块（适配工业级温宽-40℃~+85℃）。
五、品牌与品质保障
长江微电（cjiang）作为国内电感制造资深厂商，该产品具备：
- 环保合规：符合RoHS 2.0、REACH标准，无铅无卤，适配绿色设计；
- 一致性可靠：批量生产中电感值、DCR波动≤5%，满足工业级稳定性要求；
- 全检测试：每批次经高低温循环、老化测试，确保极端环境下性能稳定。
该产品平衡了尺寸、性能与成本，是小型电子设备电源设计的高性价比选择。

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.
