SRP7050TA-100M 产品概述
一、产品简介
SRP7050TA-100M 为 BOURNS 出品的车规级功率电感，规格为 10 µH ±20%，额定电流 4 A，饱和电流（Isat）7.5 A，直流电阻（DCR）约 60 mΩ。封装为 SMD，外形尺寸 6.6 × 7.3 mm，符合 AEC‑Q200 车规要求，适合要求稳定性和可靠性的汽车及工业电源应用。
二、主要特性
- 电感值：10 µH，公差 ±20%，适用于降压型 DC‑DC 以及点负载滤波回路。
- 电流能力：额定连续电流 4 A，饱和电流 7.5 A，保证在瞬态或启动时不过早进入磁饱和。
- 直流电阻：约 60 mΩ，需关注导通损耗与温升管理。
- 车规等级：通过 AEC‑Q200，适用汽车电子的温度与耐久性要求。
- 封装与装配：SMD 贴片封装，6.6×7.3 mm，兼容回流焊工艺，利于自动化生产。
三、应用场景
- 汽车电子电源模块（车载 DC‑DC、车载充电器、仪表与网关电源）
- 工业与嵌入式电源（点负载转换、LED 驱动、通信设备）
- 高电流开关稳压器与电源滤波场合，需在设计时考虑电流和温升裕度。
四、设计与使用注意事项
- 损耗与温升：DCR 为 60 mΩ，在额定电流下会产生 I^2·R 损耗（例如 4 A 时约 0.96 W），在实际应用中需评估热路径并留有余量，避免长期高温运行导致参数漂移。
- 饱和裕量：Isat=7.5 A 表示在该电流附近电感值会显著下降，设计开关电源时应保证工作峰值电流低于饱和区间或预留合适裕度。
- 频率特性：电感随频率与电流变化，应在目标开关频率及纹波条件下检验实际电感值与损耗。
- 封装布局：建议将电感尽量靠近开关器件或输出电容，缩小电流环路面积；为改善散热，可在电感下方或周围设计铜皮与过孔以导热至内层或底层散热区域。
五、可靠性与选型建议
- 车规等级确保在宽温范围与振动条件下的可靠性，但仍建议根据具体应用进行环境试验（热循环、湿热、振动）。
- 选型时参考系统的平均与峰值电流、允许温升与体积约束，若系统允许更低损耗可考虑更低 DCR 的替代型号或并联多只电感以分摊电流与降低热应力。
- 采购与生产：备注型号 SRP7050TA-100M，确认包装形式与出货条件以便与生产线对接。

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.
