LS0603-100J-N 产品概述
一、概要
LS0603-100J-N 为奇力新（chilisin）出品的贴片电感，封装尺寸为 0603，标称电感值 10 μH，公差 ±5%，直流额定电流 300 mA。该器件结合较高的电感量与小型封装，适用于空间受限、需直流阻隔或低频滤波的便携与消费类电子产品。
二、主要电气参数
- 电感值：10 μH ±5%
- 额定电流：300 mA（直流）
- 直流电阻 DCR：4.8 Ω
- 品质因数 Q：19（测试点 7.9 MHz）
- 自谐振频率 SRF：40 MHz
- 封装：0603（贴片）
注：DCR 值相对较大，在额定电流下会产生明显的直流功耗（P = I^2·R，300 mA 对应约 0.432 W），应在设计中充分考虑热量与电压降。
三、特性与设计要点
- 高频特性：Q≈[email protected] 表示在中短波频段具有中等损耗特性；SRF≈40 MHz，器件在此频率附近或以上会出现电容化行为，故工作频率应优先安排在 SRF 以下以保持电感性响应。
- 功耗与温升：高 DCR 导致在较大直流偏置下功耗迅速上升，建议在系统功耗预算中计算电感产生的功率损耗并进行热仿真或实测验证。
- 封装与寄生：0603 小型化带来封装限制，应注意引线与 PCB 阻抗匹配、靠近走线的寄生电容可能会降低有效 SRF。
四、典型应用
- 低频滤波与共模/差模电感（单端或小电流场合）
- 电源去耦与输入滤波（低功率模块、传感器供电）
- EMI 低频抑制（与电容配合构成 π 型滤波）
- 射频链路前的低频阻隔（在 SRF 以下工作）
五、PCB 布局与焊接建议
- 布置：尽量靠近噪声源或被滤波端，短且粗的进出线可减小串联寄生与能量损耗。
- 地平面：若为电源线滤波，避免把电感直接跨接到大面积地上造成额外寄生环路；若为射频用途，注意与地的耦合。
- 焊接：遵循奇力新的焊接温度曲线（若无具体资料，使用通用 0603 贴片焊接工艺），避免长时间高温回流以免影响磁性材料性能。
六、可靠性与选型注意事项
- 电流留有裕量：由于 DCR 较高，尽量选择比实际工作电流更高的额定值或采用更大封装的电感以降低温升。
- 频率匹配：若应用频段接近或高于 10–40 MHz，应评估电感在目标频率处的实际阻抗曲线，必要时做样片测量。
- 替代方案：对需要更低 DCR 或更高电流能力的场合，考虑更大封装或不同材质（低损耗磁芯）的型号。
总结：LS0603-100J-N 在小体积下提供 10 μH 的电感量，适合低功率、低频滤波与 EMC 抑制场景，但其较高的 DCR 和有限的额定电流要求在系统设计时对功耗和热管理进行充分考量。如需更多电气频率特性曲线或封装资料，可向奇力新索取器件数据手册与测试报告。

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.
