LQW15AN7N5G00D 产品概述
一、概述
LQW15AN7N5G00D 为 muRata（村田）生产的 0402 封装非屏蔽片式电感，标称电感值 7.5 nH，公差 ±2%，直流电阻（DCR）约 130 mΩ，额定直流电流 570 mA。体积小、精度高，适合对体积与一致性有较高要求的高频、电源旁路及 EMI 抑制场合。
二、主要参数
- 品牌：muRata（村田）
- 型号：LQW15AN7N5G00D
- 电感值：7.5 nH ±2%
- 直流电阻：≈130 mΩ
- 额定电流：570 mA（连续）
- 类型：非屏蔽（开放型）片式电感
- 封装：0402（小型 SMD）
三、性能特性与计算参考
- 低 DCR 有助于降低 I²R 损耗：在额定电流 0.57 A 时，理论功率损耗约 P = I²·R ≈ 0.57²×0.13 ≈ 0.042 W（≈42 mW），自热较小但仍应留有热裕度。
- 高频阻抗参考（X_L = 2πfL）：
- 100 MHz：X_L ≈ 4.7 Ω
- 900 MHz：X_L ≈ 42 Ω
- 2.4 GHz：X_L ≈ 113 Ω
由此可见在射频到微波频段表现良好，适用于高频滤波/阻断应用。
- 非屏蔽结构在体积和成本上有优势，但磁场泄露相对较大，布局需注意避免对周边电路干扰。
四、典型应用
- 高频滤波与阻断（RF 前端、天线匹配、射频旁路）
- EMI 抑制与共模/差模滤波器（与电容搭配）
- 低功率 DC-DC 旁路与输入滤波（适用于电流不超过额定值的供电路径）
- 手持设备、无线模块、射频小器件和混合信号板级滤波场合
五、PCB 布局与使用建议
- 使用厂家推荐的焊盘尺寸与间距以降低装配风险；焊盘应保证焊膏量均匀，避免 tombstone。
- 对非屏蔽电感，应远离高灵敏模拟输入、天线等以减少耦合；若作为滤波器件，靠近被滤信号端放置以减小寄生走线。
- 维持走线短、宽（必要时加铜）以减小额外串联电阻和寄生电感。
- 回流焊时遵循村田推荐曲线（一般峰值温度≤260°C），避免过度热循环。
六、可靠性与注意事项
- 避免超过额定电流和过高温度环境以防电阻升高或磁性能退化。
- 非屏蔽器件对磁场和金属遮蔽较敏感，装配时注意方向与邻近器件间距。
- 建议在方案验证阶段测量实际电感随频率/电流的变化（自谐频、Q 值、温升），以确认在目标工作频段内满足指标。

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.
