HL(富海微)推出的HL 4882是一款双N沟道增强型MOSFET,采用SOP-8贴片封装,针对中低压(≤40V)、中小功率(≤8A连续电流)场景优化设计,兼具低导通损耗、快开关速度与高可靠性,是便携式设备、小型电源等领域的实用选择。
HL 4882属于双管集成型MOSFET,将2个独立N沟道MOSFET整合至SOP-8封装内,无需额外拼接双管即可实现对称/互补功能,显著减少PCB占用面积,适合空间受限的紧凑设计场景。其电压、电流参数覆盖5V-36V主流系统(Vdss=40V留有余量),连续漏极电流8A满足多数小功率负载需求,属于中低压MOSFET中的“高性价比实用款”。
HL 4882的参数设计聚焦导通损耗控制与开关性能平衡,关键参数优势明显:
导通电阻(RDS(on))仅17mΩ(典型值,Vgs=10V下),相比同类双管MOSFET(多数≥20mΩ)降低约15%,可减少电流通过时的热损耗。结合2.9W的最大耗散功率(Pd),即使长期工作在5-6A负载下,也无需额外散热片即可稳定运行。
栅极电荷量(Qg)仅12nC(Vgs=10V、Vds=40V下),输入电容(Ciss=633pF)、反向传输电容(Crss=58pF)处于同类产品中上游水平,开关切换延迟短,适合100kHz以下的高频应用(如小型开关电源、负载开关)。
SOP-8封装内集成2个独立N沟道MOSFET,引脚布局对称,可实现“双路同步整流”“负载开关组”等功能,相比单独使用2个TO-252封装MOSFET,PCB面积减少约60%。
HL 4882采用标准SOP-8贴片封装,尺寸紧凑(约5.2mm×6.4mm),兼容自动贴装工艺,焊接可靠性高。封装内部采用优化的芯片布局,减少热阻,确保150℃高温下仍能稳定工作;引脚间距符合工业标准,避免短路风险。
HL 4882的参数匹配性使其适用于以下场景:
HL 4882的核心优势可概括为“三高一省”:
作为富海微针对中低压市场的主力MOSFET产品,HL 4882在导通损耗、开关速度与集成度上实现平衡,是替代传统单管MOSFET的理想选择。

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.
