SRN6028C-150M 产品概述

一、主要特性

  • 品牌:BOURNS
  • 器件类型:功率电感(半屏蔽绕线型)
  • 电感值:15 μH ±20%
  • 测试频率:100 kHz
  • Q 值:15(在测试频率条件下)
  • 铁氧体磁芯、绕线结构(Wirewound)
  • 额定电流:1.8 A(建议在实际应用中按厂方规格或安全裕度进行评估)
  • 直流电阻(DCR):0.098 Ω
  • 封装/代码:2424,T/R(卷盘包装适用于贴片自动化装配)

二、典型电气参数(摘要)

  • 电感:15 μH,公差 ±20%,适用于对精度要求不苛刻的电源滤波或能量储存场景。
  • Q 因子:约 15(在 100 kHz 测试条件),表明在该频段具有中等损耗水平,适合中频开关电源和滤波应用。
  • DCR(0.098 Ω):表明有一定的铜损,设计时需将该电阻产生的功耗计入热设计与效率计算。
  • 额定电流(1.8 A):为额定工作电流参考值,实际允许的连续电流与绕组发热和磁芯饱和特性相关,应参照厂方完整数据或在目标工作点下验证。

三、性能与设计要点

  1. 半屏蔽结构:比开放式绕组对外磁通泄露更小,对邻近元件的干扰降低,但不及完全封闭屏蔽器件,适合对 EMI 有一定抑制需求的点对点电源布局。
  2. 磁饱和与直流偏置效应:铁氧体磁芯在存在直流偏置(DC 偏置电流)时电感值会显著降低,设计时应考虑工作电流(尤其是峰值电流)对电感的影响并留有裕量。
  3. 损耗与效率:DCR 导致的 I^2R 损耗在高电流或连续输出应用中不可忽视,Q 值在特定频率下对交流损耗有指示意义。若目标效率较高,可考虑电阻更小或更高饱和电流的器件。
  4. 温升与热管理:在接近额定电流工作时,电感会发热。需在 PCB 布局、器件间距与散热路径上做相应安排,避免长期过热导致性能退化。
  5. 包装与装配:T/R 卷带包装利于自动化贴装,2424 尺寸代码常用于表示元件外形等级,但实际外形尺寸与高度应以官方规格书为准。

四、典型应用场景

  • DC–DC 降压/升压转换器中的电感储能元件(点对点电源)
  • 输入/输出滤波(对开关噪声的抑制)
  • LED 驱动与便携式设备电源管理
  • 汽车电子次级电源、通信设备的电源模块(需验证在汽车温度/震动条件下可靠性)
  • 工业电源与功率管理模块(在额定电流范围内用于能量转移和滤波)

五、布局与焊接注意事项

  • 布局:电感应尽量靠近相关开关器件或整流器件放置,减少环路面积以降低辐射与共模噪声。输入电容与电感排布应优化以减小寄生电感/电阻引起的振铃。
  • 焊接:遵循制造商的推荐回流焊工艺文件(Pb-free 回流曲线等),避免超过建议的峰值温度和时间以防绕线绝缘或磁芯损伤。
  • 清洗:若使用清洗剂,确认对绕线绝缘、磁芯涂层无化学侵蚀。
  • 机械应力:贴片电感对机械冲击与弯曲敏感,板上固定与过孔设计要避免在器件位置产生刚性应力集中。

六、选型与验证建议

  • 验证电感在实际工作点的电感值随 DC 偏置的变化曲线(Isat/Idc 特性)与温度特性。
  • 在目标频率与工作电流下测量实际损耗与温升,评估效率与长期可靠性。
  • 若系统对 EMI 有更严格要求,评估是否需要完全屏蔽式电感或加入额外的共模/差模滤波措施。
  • 考虑电感容差 ±20% 对回路工作点(如开关频率、峰值电流、输出纹波)的影响,必要时在设计中留有余量或选择更精密的电感品种。
  • 最终选型以 BOURNS 官方规格书和样品测试为准,批量采购建议索取并核对最新的可靠性与合格证书。

总结:SRN6028C-150M 为一款适用于中功率点对点电源与滤波场合的半屏蔽绕线电感,具有 15 μH 电感、1.8 A 额定电流与中等 Q 值的特性。选型时应重点关注 DC 偏置、电流热耗与布局 EMI 管理,并依据厂方完整数据与实测结果完成最终设计确认。

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.

Replenishment inquiry Typical RFQ workflow
