SRN3015TA-1R0Y 产品概述

一、概述

SRN3015TA-1R0Y 是 BOURNS 推出的一款微型绕线半屏蔽贴片电感,规格为 1 µH(公差 ±30%),额定直流电流 2.2 A,饱和电流(Isat)2.2 A,直流电阻(DCR)约 30 mΩ,封装尺寸为 1212(公制 3030,约 3.0 mm × 3.0 mm)。该器件以其低阻抗、较高的电流承载能力和紧凑封装,适合用于开关电源、电源滤波与电流抑制等需要中等电感量和较高电流的场合。

二、主要特性

  • 感值:1 µH,公差 ±30%(适用于对精度要求不高、以滤波与能量储存为主的应用场景)。
  • 额定电流:2.2 A(连续工作电流)。
  • 饱和电流(Isat):2.2 A(在该电流下感值下降到规定值的临界点,适用于高电流瞬变考虑)。
  • 直流电阻(DCR):约 30 mΩ(低 DCR 有利于降低功耗与温升)。
  • 结构:绕线(线绕)半屏蔽结构,兼顾磁通控制与 EMI 抑制。
  • 封装:1212(3030 公制,约 3.0 × 3.0 mm),适配 SMT 生产工艺。
  • 品牌:BOURNS,工业与消费电子常用品牌,质量与可靠性经过验证。

三、应用场景

  • DC-DC 降压/升压稳压模块(用于输入/输出电感、能量传输环节)。
  • 电源滤波:与电容配合构成输入/输出滤波网络,抑制开关噪声与射频干扰。
  • LED 驱动电源与便携设备电源管理:小体积、高电流能力满足空间受限但负载较大的场合。
  • 通信与网络设备的电源子模块:如 PoE 前端滤波、电源调节等。
  • 工业控制与嵌入式系统中对电源质量有一定要求的电流处理环节。

四、设计与选型要点

  • 电流裕量:额定电流与 Isat 均为 2.2 A,建议在系统设计中留有一定裕度(通常取 20–30%),以降低长期温升与避免接近饱和区工作。
  • DCR 对功耗影响:30 mΩ 的 DCR 在高电流下会带来额外的 I^2R 损耗,设计时需计算功耗和温升,确认封装与 PCB 散热满足系统需求。
  • 感值公差:±30% 的公差对于滤波与能量传输类用途通常可接受,但若对谐振频率或精密滤波有严格要求,应考虑更严格公差的型号或调整电路参数。
  • 屏蔽与 EMI:半屏蔽结构在抑制电磁泄漏方面优于无屏蔽绕线器件,但仍需结合 PCB 布局、接地与旁路电容的优化来控制辐射与传导干扰。
  • 温升与长期可靠性:在高电流与高环境温度下,需要关注电感自发热对感值及电阻的影响,并为器件留出合适的散热路径与间距。

五、PCB 布局建议

  • 靠近电源引脚放置:将电感尽量靠近开关器件或电源引脚,减少回路面积,降低 EMI 与寄生电感。
  • 短而宽的走线:输入/输出走线尽量短且宽,以减小串联电阻与寄生电感。
  • 多孔过孔过流:若电流路径需要跨层,建议使用多个过孔分担电流并降低热阻。
  • 接地处理:为降低共模干扰与改善散热,注意周边接地层与旁路电容的布局,避免将敏感信号线路穿插在电感附近。
  • 间距与布放:保持与发热元件及热敏元件的间距,保证散热与可靠性。

六、制造与可靠性

  • SMT 兼容:封装适用于常规 SMT 贴装与回流焊工艺,建议按照制造商推荐的回流曲线与焊膏条件操作。
  • 安装强度与检验:贴装后建议进行目视与 X 射线检查,以确认焊点质量;高电流环境下可进行温升测试以验证实际工作状态。
  • 环境适应性:依据使用场景选择合适的 RoHS/无铅工艺兼容器件及测试流程,若用于汽车或严苛工业环境,应参考厂商的额外可靠性数据与认证。

七、总结

SRN3015TA-1R0Y 为一款面向中高电流、小体积电源应用的绕线半屏蔽贴片电感,具备 1 µH 感值、2.2 A 的额定与饱和电流以及 30 mΩ 左右的低 DCR 特性,适合用于开关电源滤波与能量传输场合。选用时应注意电流裕度、DCR 引起的功耗与温升,以及合适的 PCB 布局与散热设计,以确保长期稳定可靠运行。若需更详细的电气特性曲线、频率响应或热模型,请参考 BOURNS 官方规格书或联系供应商获取完整数据表。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
