SRP1770TA-220M 产品概述
一、产品简介
SRP1770TA-220M 为 BOURNS 出品的屏蔽绕线功率电感，电感量 22 µH，公差 ±20%。本器件为表面贴装（SMD）封装，外形尺寸约 16.9 × 17.6 mm，专为需要大电流、低损耗和优秀电磁兼容性的电源应用设计。该型号为非标准/定制类型，适用于对体积、热管理与电流能力有较高要求的系统。
二、主要电气参数
- 电感值：22 µH（±20%）
- 额定电流：12 A（连续工作推荐值）
- 饱和电流 Isat：18 A（典型饱和特性时限）
- 直流电阻 DCR：最大 26.5 mΩ
- 车规等级：符合 AEC‑Q200 要求
三、产品特点与优势
- 高电流承载能力：12 A 额定和 18 A 饱和电流，适合大电流直流-直流变换器与功率滤波。
- 低 DCR：26.5 mΩ 的低直流电阻可降低铜损，提升转换效率并减小发热。
- 屏蔽绕线结构：有效抑制外泄磁场与耦合干扰，利于系统 EMC 设计。
- SMD 封装：适配自动化贴装与回流焊工艺，便于批量生产与可靠连接。
- 车规级可靠性：遵循 AEC‑Q200，适合车载电子与严苛环境下使用。
四、典型应用场景
- 汽车电子电源模块（车载 ECU、信息娱乐、ADAS 电源）
- DC‑DC 降压/升压转换器的输出滤波与储能环节
- 电机驱动与电源管理模块
- LED 驱动与工业电源系统
五、使用与布局建议
- 连续工作电流建议不要长期接近额定值，应考虑一定的热/寿命余量并进行必要的散热设计。
- PCB 布局时在电感两端采用较宽铜带并增加过孔过厚铜层，提高散热与电流承载能力；避免电感紧邻高温元件。
- 关注磁饱和效应：当瞬时电流接近或超过 Isat，电感量会下降，应在电路设计中考虑峰值电流与过载保护。
- 在高频开关场合配合适当的滤波与旁路电容以保证稳定性与低噪声性能。
六、采购与技术支持
型号：SRP1770TA-220M，品牌：BOURNS。因为为非标准/定制件，建议在采购前向供应商确认规格书、样品可得性及焊接工艺要求；必要时联系厂商获取完整的机械图、温升曲线与可靠性测试报告。
如需更详尽的电气特性曲线、温升数据或应用参考电路，我可协助整理并给出 PCB 布局与热管理的具体建议。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
