ASMD1206-100-24V 产品概述

ASMD1206-100-24V 是 JDTfuse(集电通)推出的一款高性价比 SMD 自恢复保险器(PPTC 型态),封装为行业通用的 1206 尺寸,专为 24V 及以下电源系统提供过流保护而设计。该器件在保持线路正常工作阻抗较低的同时,能够在短时异常电流出现时迅速进入限流状态并在故障消除后自动恢复,适合对成本、体积与可靠性有综合要求的消费、工业及车载电子产品。

一、主要参数

  • 耐压 (Vmax):24 V
  • 最大电流 (Imax):100 A
  • 保持电流 (Ihold):1 A
  • 跳闸电流 (Itrip):1.8 A
  • 消耗功率 (Pd):600 mW
  • 初始态阻值 (Rmin):50 mΩ
  • 跳断后阻值 (R1max):270 mΩ
  • 动作时间:300 ms
  • 工作温度:-40 ℃ ~ +85 ℃
  • 尺寸(L×W×H):3.6 mm × 1.9 mm × 1.0 mm
  • 封装:1206
  • 品牌:JDTfuse(集电通)

二、产品特性

  • 小型化封装:1206 SMD,便于自动贴片与大规模生产,节省 PCB 空间。
  • 低初始电阻:典型初始态阻值仅 50 mΩ,保证正常工作时压降和发热最小。
  • 快速限流:在超过 1.8 A 的异常电流出现时于 300 ms 内跳闸,有效保护下游电路。
  • 可恢复性:跳闸后阻值上升至最多 270 mΩ,故障消除后自动降回初始态,无需更换。
  • 宽温度范围:-40 ℃ 至 +85 ℃,适应多种环境条件。
  • 高电流承受能力:瞬时可承受高达 100 A 的浪涌电流,适合有短时大电流需求的场合。
  • 成本效益高:品质稳定、性价比优越,适合批量应用。

三、典型应用场景

  • 车载电子(24V 较低功率分支保护)
  • 工业控制电源与传感器线路保护
  • 充电设备与电源适配器输出保护
  • 通信设备、安防与监控系统的供电防护
  • 电池管理系统(作为分支保护器件)

四、设计与使用建议

  • 布局建议:器件靠近电源输入端串联放置,确保在故障点前能先感测限流。保持四周通风,尽量避免与高温器件紧邻。
  • 温度影响:工作环境温度会影响保持电流与跳闸特性,建议在设计时留有余量并做温升评估。
  • 浪涌与重复跳闸:尽管能承受短时峰值电流,但频繁的重复跳闸会影响寿命,应配合软启动、电流限制电路或缓冲元件(如 NTC、电感)使用以延长可靠性。
  • 焊接工艺:遵循 SMT 1206 常规回流焊规范,建议参考材料供应商的回流曲线,以避免过热导致性能退化。
  • 测试验证:在目标应用电路中进行 I-V、热循环与老化验证,确认在实际工况下的可靠性与动作特性。

五、包装与存储

  • 包装形式:常见为卷带盘装,适用于贴片机直接上线。
  • 存储条件:建议干燥、常温、避免阳光直射与极端湿度;长期存储前遵循防潮包装要求以防焊接问题。

六、质量与售后

JDTfuse(集电通)提供量产级品质控制,产品适合量产替换与设计使用。建议在采购前索取样品进行电气与环境适配测试,并与供应商确认批次测试报告与保质期、技术支持和售后政策。

总结:ASMD1206-100-24V 以 1206 小封装、低阻抗、高浪涌承受能力和可恢复保护特性,为 24V 及以下系统提供经济、可靠的过流防护方案,适合对空间、成本与可靠性有综合考量的应用。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
