YWLD2012-1R0K 产品概述
一、产品简介
YWLD2012-1R0K 是益嘉源（YJYCOIN）推出的一款贴片功率电感，封装为 0805（2012 公制）。标称电感值 1.0 μH，公差 ±10%，额定直流电流 1.1 A，直流电阻（DCR）为 169 mΩ，品质因数 Q = 14（测量点 7.9 MHz），自谐振频率（SRF）208 MHz。该件型面向开关电源滤波、功率去耦与高频抑制场景，兼顾体积与性能。
二、主要特点
- 小型 0805 封装，适合集成度高、空间受限的 PCB 设计。
- 1 μH 电感值满足常见降压/升压转换器和滤波回路需要。
- 相对较高的 DCR（169 mΩ）说明在高电流或高效率要求场合需关注损耗与温升。
- Q 值与 SRF 指示该件在数 MHz 至几十 MHz 频段具有良好工作特性，但在接近或超过 SRF 时电感值显著下降。
三、电气特性说明
- 额定电流 1.1 A：为避免饱和与过高温升，建议在实际设计中考虑一定裕量（典型建议 70%~80% 额定电流以下长期工作，具体以散热条件与温升要求为准）。
- DCR 169 mΩ：会带来一定的铜耗，适用于中低功率转换或作为 EMI 滤波元件；对效率敏感的电源需评估损耗影响。
- SRF 208 MHz：在高频射频应用中应避开靠近 SRF 的工作频段，作为功率滤波器在 1~20 MHz 常见开关频率范围内表现稳定。
- [email protected]：表明在该频点损耗适中，适合用作共模/差模滤波中的有源元件。
四、典型应用
- DC-DC 降压/升压转换器的输出电感或输入滤波。
- 电源线 EMI 滤波与去耦。
- 便携设备、消费电子、物联网节点等对体积有严格限制的电源模块。
- 高频抑制与谐波滤波场景（注意避开 SRF 附近）。
五、选型与布局建议
- 电流裕量：若系统连续通过接近额定电流时，应选更低 DCR 或更大电流等级的器件，或采取并联方案。
- 热管理：0805 体积小，散热能力有限，布板时保证周边有散热铜箔并减少邻近热源。
- PCB 布局：贴近噪声源或开关管放置以最小化环路面积；输入/输出电容尽量靠近电感和开关器件焊盘。
- 高频注意：若工作频率接近 10 MHz 以上，需校核电感在工作点的有效值（考虑直流偏置导致的电感下降）。
六、检验与存储
- 焊接：遵循厂家回流焊温度曲线，常用无铅回流峰值温度≤260°C。
- 检测：出货前建议检查直流电阻与标称电感值、外观及焊盘完整性。
- 存储：避免潮湿与强振动，长期存放建议按工业元器件库房标准管理。
如需更详细的温升曲线、直流偏置特性或建议的回流曲线，请提供更具体的应用条件或索取厂家完整数据手册。

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.
