ASMD1206-025 产品概述
一、产品简介
ASMD1206-025 是集电通（JDTfuse）推出的一款 1206 封装自恢复保险丝（PTC resettable fuse），专为过流保护和短路保护设计。器件通过 UL 认证，品质稳定、性价比高，适合消费电子、移动设备、外围接口及板级电源保护等场景。
二、主要参数
- 额定耐压（Vmax）：16 V
- 最大短时承受电流（Imax）：100 A（短时浪涌能力，非持续导通电流）
- 保持电流（Ihold）：250 mA
- 跳闸电流（Itrip）：500 mA
- 功耗（Pd）：600 mW
- 初始态阻值（Rmin）：350 mΩ
- 跳断后阻值（R1max）：2.7 Ω
- 动作时间：80 ms（在规定过流条件下）
- 工作温度：-40 ℃ ~ +85 ℃
- 外形尺寸：3.6 mm × 1.9 mm × 1.0 mm（1206 封装）
- 认证：UL 认证
三、产品特性
- 响应迅速：在过流条件下 80 ms 内动作，能有效限制故障电流，保护后级电路与器件。
- 自恢复性：故障消除后可自动冷却恢复导通，减少更换维护成本。
- 体积小、易贴装：1206 标准封装，兼容常见 SMT 贴片工艺，便于自动化生产。
- 可靠耐用：工作温度范围宽，适应多数消费与工业类应用环境；UL 认证提升可靠性与安全性可追溯性。
- 经济实用：在保证保护性能的前提下，提供较高性价比，适合大批量设计。
四、典型应用
- USB、HDMI 等接口过流保护
- 电池组与充电保护电路（限流与短路防护）
- 主板、子板电源线上板级保护
- 消费类电子与便携设备的端口保护
- 电源适配器与小功率稳压模块的输入侧保护
五、选型与使用建议
- 额定选择：Ihold 应大于正常工作电流并留有裕量（一般 25%~50%），以避免误动作；Itrip 则需高于短时浪涌电流但低于故障极限。
- 浪涌能力：标称 Imax 为短时承受能力，若电路存在频繁大幅浪涌或长时冲击，应评估是否需要更大规格或并联/串联保护方案。
- 布局与散热：建议靠近被保护电源入口安装，避免与高温元件紧密堆叠；保持焊盘良好接触以利散热与可靠焊接。
- 重复动作：自恢复保险丝多次跳闸后阻值可能逐步上升，长期频繁故障应排查根本原因并更换器件。
- 焊接兼容性：采用推荐的 SMT 回流工艺，避免超出元件耐受温度范围，参照厂家详细焊接规范。
六、包装与认证
- 封装：1206 SMT，适合高速贴片生产线。
- 认证：通过 UL 认证，便于应用于需认证的整机产品。
- 品牌：JDTfuse（集电通），在板级保护元件领域具有稳定制造能力与供应链支持。
总结：ASMD1206-025 以其小巧的 1206 封装、250 mA 的保持电流与 500 mA 的跳闸电流，结合 UL 认证和较高的短时浪涌承受能力，适用于多种板级过流保护场景。选型时请根据实际工作电流与浪涌特性留足裕量，并遵循布局与焊接建议以获得最佳可靠性。

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.
