FXC0630-R33M 产品概述
一、产品简介
FXC0630-R33M 是 cjiang（长江微电）推出的一款高电流一体成型（molded）SMD 电感，封装尺寸 7.3 × 6.6 × 2.8 mm，标称电感值 330 nH，公差 ±20%。额定持续电流为 20 A，饱和电流（Isat）32 A，直流电阻（DCR）仅 3.9 mΩ，适用于对体积、导电损耗和电流承载能力有较高要求的电源滤波与储能场合。器件为一体成型结构，机械强度和可回流焊接性良好，便于自动贴装生产。
二、主要性能亮点
- 高电流承载：20 A 额定电流，32 A 饱和电流，适合大电流开关电源与负载路径。
- 低功耗：3.9 mΩ 的低 DCR，有效降低铜损和温升。
- 紧凑封装：7.3×6.6×2.8 mm SMD 封装兼顾功率密度与布板空间。
- 一体成型：提高抗振动、耐焊接和长期可靠性，适合车规级或工业级应用（视具体认证）。
三、典型应用场景
- DC–DC 降压/升压转换器（同步整流电源）
- CPU/FPGA/ASIC 等负载侧电源滤波（点式电感）
- 高功率 LED 驱动、车载电源模块、通信设备电源轨
- USB PD / 快充电源、功率放大器输出滤波
四、典型电路与布局建议
- 将电感放置于开关器件与输出电容之间，尽量缩短开关回路环路面积以降低 EMI。
- 为减小温升，功率回路走宽铜厚，并在电感下方或附近增加铜层及过孔以利散热（根据 PCB 层数布置散热通路）。
- 回流焊工艺遵循普通无铅回流曲线，避免超温或长时间高温。
- 在高电流路径使用低阻抗焊盘与良好焊接，避免潮湿环境下的焊点腐蚀或应力集中。
五、选型与可靠性注意事项
- 直流偏置影响：在大直流电流下电感值会下降，Isat=32 A 为进入磁饱和并出现显著电感下降的参考值；实际使用中应在目标电流下验证电感保留率是否满足滤波需求。
- 热升与寿命：长期接近或超出额定电流会导致温度升高并影响寿命，建议预留一定余量并做温升测试。
- 测试条件：DCR 标准通常在 20°C 测量，实际应用温度上升会增加 DCR。
- 环境与可靠性：若应用于汽车或高可靠场景，需确认供应商可提供相应可靠性与温度循环试验数据。
六、结论
FXC0630-R33M 以其高电流能力、低 DCR 及紧凑的一体成型封装，适合要求高效率与高功率密度的电源应用。选型时请结合系统工作电流、直流偏置对电感值的影响及散热条件，必要时向厂商索取电感随直流电流的曲线与样品做实测验证，以确保长期稳定运行。

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.
