SM4532-101MT是顺翔诺(SXN)推出的一款非屏蔽贴片功率电感,核心面向中小功率电子设备的电源管理、滤波及EMI抑制场景。其核心参数清晰明确:
100uH属于中低频段常用电感值,适配DC-DC转换、电源滤波等电路(如5V转3.3V的降压模块);±20%的精度兼顾成本与性能,适合消费电子、IoT设备等对精度要求不苛刻的场景,无需因校准增加额外成本。
450mA是该电感的“临界工作电流”——当直流电流超过此值时,磁芯会饱和,电感值骤降(通常下降≥30%),导致纹波增大、效率降低。实际应用中需确保负载电流≤450mA,避免性能失效。
1.52Ω的DCR是绕组的直流损耗指标,直接影响电路效率。以450mA工作电流计算,损耗功率约为0.31W(I²R=0.45²×1.52),属于同规格产品的常规水平,兼顾成本控制与损耗控制。
采用SMD 4.5×4mm贴片封装,具备以下优势:
该电感主要覆盖三类场景:
顺翔诺对该产品完成常规可靠性测试(温度循环、振动测试),工作温度范围为**-40℃~+85℃**,满足大部分场景的环境要求。需注意:
该产品以“小体积、高性价比、适配常规场景”为核心优势,是中小功率电子设备电源设计的常用选择。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
