YNR4030-330M功率电感产品概述
一、产品基本属性
YNR4030-330M是益嘉源（YJYCOIN） 推出的一款表面贴装（SMD）功率电感，属于磁胶屏蔽型电感范畴。型号命名中，“4030”对应贴片封装尺寸（长×宽×高=4mm×4mm×3mm），“330M”明确核心参数：电感值33μH，精度±20%（行业中“M”为20%精度代码）。该产品专为小功率电源、驱动电路等场景设计，兼顾小型化与性能稳定性。
二、核心电气参数详解
- 电感值与精度：标称电感值33μH，精度±20%（实际范围26.4μH~39.6μH），满足大多数功率电路对电感值的基本需求，无需高精度校准即可稳定工作。
- 额定电流：持续工作额定电流840mA，是电感不出现磁饱和、电感值下降超10%（行业常规标准）的最大连续电流。若电路存在脉冲电流，需按峰值电流适当降额。
- 直流电阻（DCR）：典型值330mΩ，是绕组的直流电阻。低DCR意味着功率损耗小（840mA下损耗约0.23W），可有效降低电路发热，提升系统效率。
三、封装与物理特性
采用SMD 4×4×3mm 贴片封装，尺寸紧凑（与0805贴片电阻相当），适配自动化贴装生产线，兼容无铅回流焊工艺。产品重量约0.1g，可大幅节省PCB空间，适合便携式设备、小型模块的高密度设计。引脚采用标准焊盘，焊接后机械强度可靠，抗振动性能满足一般电子设备环境要求。
四、屏蔽特性与应用优势
作为磁胶屏蔽电感，相比非屏蔽电感具有显著EMI抑制能力：磁胶材料可屏蔽绕组电磁场，减少对周边敏感电路（如射频模块、传感器）的干扰，同时降低对外辐射，提升系统EMC。此外，磁胶屏蔽比传统铁氧体屏蔽成本更优，耐温范围宽（-40℃~+125℃，参考 datasheet），适合宽温环境。
五、典型应用场景
YNR4030-330M的参数与封装特性，使其广泛适用于：
- 小型开关电源：手机充电器、USB-C适配器、微型DC-DC转换器（5V转3.3V）；
- LED驱动电路：小功率LED灯串（台灯、夜灯）的恒流/恒压模块；
- 便携式设备：智能手环、蓝牙耳机、智能手表的电源管理模块；
- 通信模块：WiFi、蓝牙、LoRa模块的滤波与电源电感（EMI敏感场景）；
- 消费电子配件：无线充电器、移动电源的升压/降压电路。
六、选型与使用注意事项
- 电流降额：若存在脉冲电流，峰值电流需控制在额定电流的1.2~1.5倍内，避免磁饱和；
- 精度匹配：±20%精度适合功率电路（电感波动对输出影响小），谐振电路需换高精度型号；
- 散热设计：连续工作时可增加焊盘面积或散热铜箔，避免局部过热；
- 屏蔽需求：EMI敏感场景优先选此款，无严格要求可考虑非屏蔽电感（成本更低）。
该产品以“小尺寸、低损耗、强屏蔽”为核心特点，是小功率电子设备电源与驱动电路的高性价比选型。

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.
