ASMD2920-300-30V 产品概述
一、产品简介
ASMD2920-300-30V 是集电通（JDTfuse）推出的一款小型过流保护元件，采用 2920 封装（尺寸：7.98mm × 5.44mm × 1.2mm），面向要求体积小、响应稳定、性价比高的电子设备。产品具备 UL 认证，适合消费电子、通讯设备及工业控制等多种场景的线路保护设计。
二、主要电气参数
- 额定耐压（Vmax）：30 V
- 最大通过电流（Imax）：40 A
- 保持电流（Ihold）：3 A
- 跳闸电流（Itrip）：6 A
- 功耗（Pd）：1.5 W
- 初始态阻值（Rmin）：12 mΩ
- 跳断后阻值（R1max）：48 mΩ
- 动作时间（典型）：20 s
三、环境与机械特性
- 工作温度范围：-40 ℃ 至 +85 ℃
- 封装：2920，外形紧凑，便于自动贴片/手工焊接与布局优化
- 高可靠性设计，适应多次过流-恢复循环（视工况而定）
四、产品特点与优势
- UL 认证保证品质与可靠性，方便整机取得安规合规性
- 阻值低（12 mΩ 起）可降低正常工作损耗，满足高电流传输需求
- 清晰的保持电流与跳闸电流设定（3A / 6A）便于工程师在电路保护策略中选型与配套设计
- 成本效益高，适合大批量量产与替换件应用
五、典型应用场景
- 消费类电源管理（充电器、移动电源）
- 通信设备与基站模块的线路保护
- 工业自动化与控制器件的短路/过流保护
- 汽车电子辅助电路（须配合整机热与机械耐受验证）
六、选型建议
在选用时建议关注系统工作电流波动与启动电流（瞬态），确保 Ihold 与 Itrip 在目标工况下满足保护与不误动作的平衡；同时考虑工作环境温度对动作时间与触发点的影响。若需高温或更快动作，应与厂商确认实测曲线及寿命数据。

Send RFQ
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.
