产品名称: AO4882
类型: 双 N-通道 MOSFET
封装结构: SO-8
品牌: AOS
AO4882 是一款高效能的双 N-通道场效应管 (MOSFET),设计用于各种电源管理和开关应用。凭借其出色的电气特性,AO4882 能够在多种环境下提供高效能,确保系统的稳定性和可靠性。
导通电阻 (RDS(on)): 在 25°C 时,最大导通电阻为 19 毫欧,额定电流为 8A 和 Vgs 为 10V 时表现优异。低导通电阻的特性令其在开关一分钟时损失低,有助于减少发热,提高整体系统效率。
连续漏极电流 (Id): AO4882 可承受高达 8A 的连续漏极电流,使其在许多高电流驱动应用中表现良好,可以有效驱动负载而不出现过载问题。
漏源电压 (Vdss): 该器件具有最高 40V 的漏源承受能力,使其适合于常见的低压电源和驱动系统中。过流过压能力的结合确保了器件的安全性和长久性。
工作温度范围: AO4882 具有宽广的工作温度范围,从 -55°C 到 150°C。此特性使其适合高温、低温等极端环境,适合用于汽车、工业控制等要求高可靠性的场合。
输入电容 (Ciss): 在 20V 的条件下,输入电容最大值为 415pF。较低的输入电容意味着在驱动和开关时可能的延迟较短,提高了响应速度。
栅极电荷 (Qg): 在 Vgs 为 10V 时,栅极电荷最大值为 12nC。这意味着在开关过程中,低的栅极电荷有助于降低驱动功耗,提高整体的效率。
栅极阈值电压 (Vgs(th)): AO4882 具有最大阈值电压为 2.4V(@ 250µA),能在较低的栅极电压下可靠导通,便于逻辑电平的驱动控制。
AO4882 的设计使其广泛适用于各类电子设备,特别是在以下应用中表现突出:
DC-DC 转换器: 在电源管理和电能传输的过程中,AO4882 的低导通电阻和高效能使其成为理想选择,能够实现高转换效率,在功率转换时减少能量损失。
电机驱动: 适用于各种电机控制系统,AO4882 可以用作开关元件,在控制电机启停和调速方面提供高处理能力和高稳定性。
负载开关: 能够快速有效地连接和断开负载,AO4882 可应用于智能家居、工业设备等多种场合,实现高效的负载管理。
汽车电子: 由于其良好的高温耐受能力和高可靠性,AO4882 可用于汽车的电源切换和电机驱动,确保电子系统的稳定运行。
AO4882 是一款技术先进、性能卓越的双 N-通道 MOSFET,适用于多种应用场景。凭借其低导通电阻、优秀的热性能和广泛的工作温度范围,AO4882 为设计师和工程师在创建高效、可靠的电子设备时提供了理想解决方案。无论是在电源管理、电机驱动还是负载开关应用中,AO4882 都能够显著提升系统的性能,降低能耗,确保设备的长期稳定运行。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
