FNR6020S331MT 产品概述
一、产品简介
FNR6020S331MT 是长江微电（cjiang）出品的一款磁胶屏蔽功率电感，标称电感值 330 µH，公差 ±20%。为 SMD 封装（6×6 mm）器件，适用于对体积和电磁兼容有一定要求的低功率滤波与储能场合。
二、主要参数
- 电感值：330 µH ±20%
- 额定电流：390 mA
- 饱和电流（Isat）：330 mA
- 直流电阻（DCR）：3.419 Ω
- 类型：磁胶屏蔽电感（屏蔽型、SMD）
- 封装尺寸：6 × 6 mm（具体高度与引脚定义请参照厂商数据表）
三、特性与优势
- 屏蔽结构：减少外泄磁场，利于 EMI 控制与多器件密集布局。
- 紧凑体积：6×6 mm SMD 适合表贴工艺，便于自动化装配。
- 大电感量：330 µH 适合低频滤波、延时与能量储存用途。
- 商用级别：±20% 公差，工控与消费类电路常用。
四、适用场景
- 低速 DC‑DC 开关电源的输入/输出滤波；
- 功率/信号线的低通滤波与尖峰抑制；
- 电源管理与噪声抑制场合，特别是对体积与屏蔽有要求的板级设计。
五、在电路中使用建议
- 注意 DCR 较大：3.419 Ω 在高电流下会带来较大 I^2R 损耗（例如 390 mA 时约 0.52 W），因此更适合低电流场合。
- 饱和与裕量：Isat 为 330 mA，建议实际工作电流控制在较低水平（如 ≤200–250 mA）以避免感值下降与过热。
- 布局与散热：尽量靠近电源管脚布置，保证良好焊盘热散、避免热量堆积。
- 选型核对：在设计前查看厂商完整数据表（温漂、频率特性、再流曲线与封装图纸），并根据实际频率与纹波电流做仿真或样机验证。
六、封装与采购提示
- 标注型号：FNR6020S331MT，品牌：cjiang（长江微电）。
- 采购时确认最小起订量、包装方式（卷带/托盘）与 RoHS 等合规性。
- 若需更低 DCR 或更高电流能力，可考虑同系列或其它产品线替代，并与供应商沟通样品测试。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
