CS0805-R47J-S 产品概述
一、产品简介
CS0805-R47J-S 为奇力新（chilisin）出品的贴片电感，封装规格为 0805（常用表面贴装尺寸），标称电感值 470 nH，公差 ±5%。该器件设计用于抑制高频干扰与滤波用途，兼顾小型化与射频性能，适合空间受限的电子产品使用。
二、主要特性
- 电感值：470 nH，±5% 精度，适用于精密滤波设计。
- 额定直流电流：250 mA，适合低功耗或信号线级别应用。
- 直流电阻（DCR）：1.76 Ω，较高的 DCR 提示器件在直流通过时会产生显著压降和功耗。
- 品质因数（Q）：33 @ 50 MHz，表明在中高频段具有较好的选择性和能量存储效率。
- 自谐振频率（SRF）：100 MHz，上限频率特性适合几十 MHz 范围内的滤波与阻抗匹配。
三、电气与热工注意事项
- 在额定电流 250 mA 下，直流压降约为 0.44 V（0.25 A × 1.76 Ω），功耗约 0.11 W（I^2R），长期工作时需评估局部温升对电感稳定性的影响。
- 由于 DCR 相对较大，不建议用于需要低串联电阻的电源传输路径；更适合信号滤波、EMI 抑制或旁路网络。
- 在靠近自谐频率工作时，请考虑电感实际呈现电容化行为，避免在 SRF 附近作为纯感性元件使用。
四、典型应用场景
- 高频信号线或射频前端的抗干扰滤波；
- EMI / RFI 抑制网络，用于通讯设备、消费电子和工业控制器；
- 复杂多层板中需要小体积滤波器或阻尼元件的场合。
五、PCB 布局与装配建议
- 采用标准 0805 焊盘设计，焊盘与元件焊接面保持良好对齐，焊膏用量以保证可靠焊接为主；
- 尽量缩短与受保护信号线的走线长度，减少寄生电感与电阻；
- 回流焊加工兼容，但应遵循材料的焊接温度上限与热循环规范，避免过度机械应力导致裂纹或接触不良；
- 对于敏感射频路径，建议在布局阶段进行仿真验证元件在频域内的影响。
六、可靠性与测试
- 建议在设计验证阶段做温度循环、湿热、和震动测试以评估在目标环境下的长期稳定性；
- 对关键应用进行实际频率范围内的 S 参数或阻抗测试，确认 Q 值与 SRF 在实际电路中的表现。
七、采购与封装信息
- 品牌：chilisin（奇力新）；型号：CS0805-R47J-S；封装：0805（表面贴装）。
- 选型时请确认所需的电流承载能力与允许压降，若应用需更低 DCR 或更高电流，请咨询替代型号或同系列产品。
该器件以其小型化与中高频良好 Q 值，适用于对空间与频率响应有要求的滤波与 EMI 抑制场合；选择时请综合考虑 DCR 带来的功耗与热管理需求。

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.
