ASMD0805-010-30V自恢复保险丝产品概述

一、产品定位与核心身份

ASMD0805-010-30V是JDTfuse(集电通) 推出的一款贴片式自恢复过流保护器件,核心价值在于故障时自动切断电流、故障解除后自主恢复导通,无需手动更换,有效简化电路维护流程。该器件采用0805标准贴片封装,适配小型化、高密度电子电路设计,针对30V以内低压、100mA级小电流场景优化性能,是消费电子、可穿戴设备等领域的可靠防护方案。

二、关键性能参数深度解析

产品参数围绕“过流响应”“功耗控制”“环境适应”三大核心维度设计,具体解读如下:

1. 过流保护触发逻辑

  • 保持电流(100mA):常态下可稳定承载的最大工作电流,电流≤100mA时器件保持低阻态,不影响电路正常功能;
  • 跳闸电流(300mA):触发动作的阈值电流,当电流持续超过300mA时,器件会在1.5s内快速动作,切断故障电流;
  • 最大峰值电流(100A):可耐受的瞬时冲击电流上限,避免电路突发浪涌导致误触发或器件损坏。

2. 电阻与功耗特性

  • 初始态阻值(最小750mΩ):常态下的低电阻设计,可显著降低器件自身功耗(额定500mW),避免对电路信号传输、电池续航造成干扰;
  • 跳断后阻值(最大6Ω):故障时切换至高阻态,有效抑制故障电流扩散,保障后端电路安全。

3. 环境与电气极限

  • 工作温度范围(-40℃~+85℃):覆盖低温(如北方户外)、高温(如设备内部散热)场景,满足工业、车载等宽温需求;
  • 最大耐受电压(30V):适配低压直流电路(如电池供电设备),电压超过30V时器件可稳定工作。

三、封装特性与适用电路场景

ASMD0805-010-30V采用0805贴片封装(尺寸约2.0mm×1.2mm),具备三大封装优势:

1. 小型化适配

体积紧凑,可集成于手机、智能手环等便携设备的高密度PCB板中,不占用额外空间;

2. 生产兼容性

支持SMT自动贴装,生产效率高,降低人工成本,适合批量制造;

3. 散热效率

贴片结构利于热量快速散发,配合低初始阻值,减少器件自身发热积累,延长使用寿命。

结合参数特性,该器件适用于以下场景:

  • 30V以内低压直流电路的过流保护;
  • 小电流(≤100mA)负载的持续工作防护;
  • 对维护便捷性要求高的终端产品(如消费电子、智能家居)。

四、品牌可靠性与应用优势

JDTfuse(集电通)作为专业过流保护厂商,ASMD0805-010-30V延续了其高可靠性特点:

1. 反复使用性

自恢复特性支持多次故障-恢复循环,无需像一次性保险丝那样更换,降低售后维护成本;

2. 快速响应

最大动作时间1.5s,可在故障初期切断电流,减少后端器件(如IC、传感器)损坏概率;

3. 宽温稳定性

-40℃至+85℃的工作范围,确保在极端环境下性能稳定,避免因温度变化导致误触发;

4. 低功耗设计

500mW额定功耗,常态下几乎不影响电路整体功耗,适合电池供电的便携设备。

五、典型应用领域梳理

该器件的参数与封装特性,使其在多个领域得到广泛应用:

1. 消费电子

手机、平板、TWS耳机的电池保护电路,防止过充、过放导致的过流;

2. 可穿戴设备

智能手环、手表的传感器与控制模块防护,应对突发电流波动;

3. 智能家居

智能门锁、温湿度传感器的低压控制电路保护,提升设备可靠性;

4. 工业低压控制

小型PLC、传感器节点的过流防护,适配户外、车间等宽温环境。

总结

ASMD0805-010-30V凭借自恢复特性、低功耗、小型化封装及宽温适应性,成为低压小电流电路过流保护的高性价比选择,可有效提升终端产品的可靠性与维护便捷性,满足消费电子、可穿戴等领域的多样化需求。

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.
