BOURNS SRN8040-2R2Y 功率电感产品概述
一、核心参数总览
BOURNS SRN8040-2R2Y是一款针对大电流功率电路设计的表面贴装（SMD）电感，核心参数明确，可直接支撑电路选型：
参数项 规格值 标称电感值 2.2μH 电感精度 ±30% 额定电流（温升） 6.3A 饱和电流（Isat） 7.4A 直流电阻（DCR） 13mΩ（典型值） 封装尺寸 SMD，8.2×7.9mm（长×宽） 品牌 BOURNS（伯恩斯）二、关键性能指标深度解析
1. 电感与精度：适配宽频率功率需求
该电感标称2.2μH，精度±30%（实际值范围1.54μH~2.86μH），符合商用级功率电感的常规精度标准。此电感值可有效匹配几十kHz至几MHz频段的开关电源（如DC-DC转换器），兼顾能量储能与纹波抑制功能——既不会因电感过大导致响应延迟，也不会因过小影响滤波效果。
2. 电流特性：连续工作与过载耐受平衡
- 额定电流（6.3A）：指电感连续工作时，温度升高不超过行业标准（通常40℃~50℃）的最大电流，反映长期可靠工作能力；
- 饱和电流（7.4A）：指电感值下降≤10%时的最大电流，体现瞬间过载耐受能力。该产品饱和电流高于额定电流，可应对电路负载突变、瞬间浪涌等场景，避免电感饱和导致的电源效率骤降。
3. 低DCR：降低损耗提升转换效率
直流电阻仅13mΩ，属于同体积功率电感的低损耗水平。在6.3A额定电流下，导通损耗仅约(6.3^2×0.013≈0.51W)，可显著减少发热，降低散热设计压力，提升电源整体转换效率（尤其适合对效率敏感的便携式设备）。
三、封装与物理特性：紧凑型设计适配高密度应用
SRN8040-2R2Y采用表面贴装（SMD）封装，尺寸8.2×7.9mm（长×宽），属于小体积功率电感范畴：
- 生产兼容性：SMD封装适配自动化生产线，可降低组装成本；
- 空间适配性：小尺寸可节省电路板面积，适合笔记本电脑、车载模块等对体积敏感的紧凑型设计。
四、典型应用场景
结合参数特性，该电感的核心应用场景包括：
- 消费电子电源：笔记本电脑、平板电脑的CPU供电DC-DC转换器；
- 车载电子：车载充电机（OBC）、12V转5V/3.3V的车载DC-DC模块；
- 工业控制：小型PLC、工业电源模块的滤波/储能电路；
- 通信设备：路由器、交换机的电源纹波抑制电路。
五、品牌与选型优势
BOURNS作为全球知名元器件制造商，其产品以高可靠性、一致性著称，SRN8040-2R2Y的选型优势具体体现为：
- 可靠性：符合商用级与工业级标准，可应对-40℃~+125℃的宽温度范围；
- 性能平衡：在小体积下实现“大电流+低损耗+高过载”的三重平衡；
- 兼容性：参数匹配Buck、Boost等主流开关电源拓扑，适配多种PCB设计。
该产品凭借清晰的参数、可靠的性能与紧凑的封装，成为功率电路设计中功率电感选型的优质选项。

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.
