  • 电流 - 保持 (Ih): 最大值 300mA
  • 电流 - 跳断 (It): 600mA
  • 跳断时间: 100ms
  • 初始电阻 (Ri): 最小值 200mΩ
  • 跳断后电阻 (R1): 最大值 1.75Ω
  • 工作温度: -40°C ~ 85°C
  • 封装类型: 表面贴装型 (SMD)
  • 封装规格: 1812 (4532mm)
  • 尺寸: 0.179" x 0.128" (4.55mm x 3.24mm)
  • 厚度 (最大值): 0.035" (0.89mm)

3. 应用领域

MINISMDC030F-2 适用于各种需要电流保护的场合,尤其是在电源管理、消费电子、汽车电子等领域。其设计能够承受高达40A的电流负荷,并且在发生过流时,能够迅速断开电路,防止设备受损。此产品特别适合用于:

  • 电池供电设备
  • 信息技术产品(如服务器和路由器)
  • 电动车辆和混合动力汽车
  • 个人电子产品(如智能手机、平板电脑)

4. 工作原理

MINISMDC030F-2 的工作原理基于 PTC 材料的特性。当电流经过保险丝时,阻值较低,允许正常工作的电流通过。一旦电流超过设定的跳断电流(600mA),PTC 材料会迅速加热并使其电阻显著增加,从而有效切断电路。这一过程通常在 100ms 内完成。待故障条件解除后,保险丝会自动恢复到正常工作状态,从而提供持续的保护。

5. 性能优势

  • 自复位设计: MINISMDC030F-2 的自复位功能使其能够在电流恢复正常后自动复位,大大减少了维护成本和时间。
  • 高耐受电流: 其最大连续承载电流为 40A,为各种高功率应用提供可靠的保护。
  • 广泛的工作温度范围: 该产品在 -40°C 到 85°C 的环境温度下稳定工作,适用范围广泛。
  • 低初始电阻: 它的初始电阻为最小 200mΩ,提供良好的电流通过能力,降低了功耗和发热。

6. 封装与安装

MINISMDC030F-2 采用表面贴装型(SMD)封装,方便在自动化生产中进行安装。其1812(4532公制)封装尺寸使其适用于空间有限的应用场合,具有良好的散热性能和机械强度。

7. 可靠性与合规性

作为一款面向汽车和工业市场的电子元件,MINISMDC030F-2 在设计及制造过程中严格遵循国际标准,确保其质量和可靠性。它的高性能和稳定性使其在复杂环境中也能可靠工作。

8. 结论

MINISMDC030F-2 是一款出色的自复位保险丝,适合于多种高可靠性和高安全性要求的电气设备中。凭借其优越的电流保护性能及广泛的应用领域,MINISMDC030F-2 无疑是电源保护方案中不可或缺的重要元件。对于设计工程师和设备制造商来说,这是一个值得信赖的选择,助力于产品的安全与韧性。

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
