PWCWAQ2012F-470KTT（47µH ±10% 0805 绕线片式贴片电感）产品概述
一、产品概述
PWCWAQ2012F-470KTT 是谱罗德（PROD）推出的一款0805封装绕线片式贴片电感，标称电感值47µH，公差±10%，额定直流电流160mA，直流电阻（DCR）4.42Ω，自谐振频率（SRF）约10MHz。体积小、适合贴片生产，适用于低频滤波与小电流电源/信号滤波场合。
二、主要性能与电气特性
- 电感值：47µH ±10%（常温、低偏置条件测量）
- 额定电流：160mA（厂方额定值，指在规定温升或电感降容限内的持续电流）
- 直流电阻（DCR）：4.42Ω（较高，使用时需关注功耗与发热）
- 自谐振频率（SRF）：约10MHz（高于SRF时电感性能下降，呈电容性）
- 类型：绕线片式（wire-wound chip），0805/2012公制封装，贴片回流兼容
三、应用场景
适合用于：
- 小电流电源线低频滤波（如传感器、模拟前端、RTC模块电源滤波）
- 信号线EMI抑制与防噪音处理（音频、低速串行总线滤波）
- 小型LC滤波器、电源去耦与噪声整形电路
不建议用于大电流开关稳压器主电感或高频高电流场合，因DCR与额定电流受限。
四、选型与注意事项
- DCR 4.42Ω 会在160mA时产生约0.11W的功耗（P = I^2·R），长期使用应评估器件温升和环境散热条件。
- SRF = 10MHz 表明该电感在高于约1–2MHz范围内电感值会显著下降，若目标工作频率接近或超过SRF，应改用高SRF或更低电感值器件。
- 额定电流为热与电性能的综合指标，若电路有脉冲大电流或较高温度，需适当降额使用以避免磁饱和或温升过大。
- 对空间和布局敏感的应用，0805封装提供良好贴装性，但实际外形尺寸请参照厂方数据手册。
五、PCB与工艺建议
- 器件尽量靠近噪声源或滤波目标放置，以减小环路面积。
- 保持走线宽度与过孔足以承载最大电流，避免走线过细导致局部过热。
- 回流焊兼容常见无铅工艺，但应遵循厂家推荐的温度曲线以避免磁性材料性能退化。
- 储存与贴片前避免潮湿，贴装后建议按实际工况进行温升验证。
六、测试与验证
建议在目标工作频率与温度下验证：
- 使用阻抗分析仪在典型频段复测电感值与Q值，确认SRF位置；
- 用精密欧姆表测DCR；
- 在最大工作电流下测量温升与电感降容，检查是否满足系统要求。
七、采购与替代
品牌：PROD（谱罗德），型号：PWCWAQ2012F-470KTT，封装0805（2012）。若需替代，可寻找相同性能的0805绕线片式47µH器件，但注意比较DCR、SRF与额定电流三项关键参数以确保替换兼容。
如需我提供数据手册要点解读、样品评估建议或替代料比对，请告知应用场景与工作频率/电流条件。

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.
