FHD252012S-3R3MT是长江微电(cjiang)推出的小型化表面贴装(SMD)功率电感,定位于中电流密度、高密度布局的电源电路场景。型号命名中:
该电感的核心参数围绕“功率承载、效率与稳定性”设计,具体解析如下:
标称电感值3.3μH,精度±20%,覆盖DC-DC转换、滤波、储能等常见电源应用的电感需求。20%的偏差范围已满足大部分工业/消费电子的设计裕量(若需更高精度,需结合电路功能调整,如射频滤波需±10%以内)。
小阻值是该电感的核心优势:在1.8A连续电流下,损耗仅为1.8²×0.175≈0.57W,可有效控制电感自身发热,提升整体电路能效(尤其适合对电池续航敏感的便携式设备)。
采用无铅SMD封装,符合RoHS环保标准,焊接兼容性优异:
该电感的参数与封装特性,使其成为以下场景的优选:
长江微电(cjiang)是国内专注功率电感研发的厂商,该产品经过严格可靠性测试:
该电感凭借“小尺寸、高电流密度、低损耗”的特点,成为消费电子、小型电源领域的高性价比选型,可满足大部分中端电源电路的设计需求。

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.
