MINISMDC075F/24-2 产品概述
概念与简介
MINISMDC075F/24-2 是由美国力特（Littelfuse）推出的一款聚合物 PTC 可复位保险丝，专门设计用于提供过流保护。这款产品在电气和电子电路中具有卓越的性能，最大可以承受 24V 的电压和 40A 的电流。这种保险丝采用表面贴装型（SMD）封装，便于在各种电子设备中集成和使用。
基本特征
- 类型: 聚合物 PTC 可复位保险丝
- 最大电压: 24V
- 最大电流: 40A
- 保持电流 (Ih): 最大 750mA
- 跳断电流 (It): 1.5A
- 跳断时间: 300ms
- 初始电阻 (Ri): 最小 90 mOhms
- 跳断后电阻 (R1): 最大 290 mOhms
- 工作温度: -40°C 至 85°C
- 安装类型: 表面贴装型
- 封装/外壳: 1812 (4532 公制)，凹陷
- 尺寸: 0.181" 长 x 0.128" 宽（4.60mm x 3.24mm）
- 最大厚度: 0.057"（1.46mm）
工作原理
PTC 可复位保险丝是一种具自恢复能力的过流保护元件。其工作原理是基于聚合物的电阻随温度变化的特性。当电流通过该元件时，如果电流保持在 750mA 以下，元件将处于正常工作状态。但是，一旦电流超过 1.5A，内部材料会迅速升温并导致阻值大幅增加，从而切断电路，防止过流损害设备。经过一段时间的冷却后，保险丝会自动复位，恢复正常工作状态。
应用领域
由于其优秀的电性能和广泛的工作温度范围，MINISMDC075F/24-2 在多个领域找到了应用，包括：
汽车电子: 在现代汽车的电气系统中，过流保护极为重要。这种保险丝可以保护汽车的电路免受短路或过流情况的影响，确保汽车电气元件的安全运行。
消费电子: 在手机、平板、笔记本电脑等消费电子产品的充电电路和电池管理系统中，能有效防止过流导致的热损伤。
工业设备: 在工业自动化设备中，确保电气元件免受意外短路或过载的保护，增强设备的稳定性和安全性。
家庭电器: 在各种家用电器如冰箱、洗衣机等中，提供必要的过流保护，延长设备的使用寿命。
安装与使用
作为表面贴装元件，MINISMDC075F/24-2 便于快速且高效地进行自动化生产。在焊接过程中，建议遵循相关的焊接工艺和温度曲线，以保证元件的性能和可靠性。由于其小尺寸设计，该元件可轻松贴合于各种紧凑型电路板中。
总结
MINISMDC075F/24-2 是一款集高性能、可靠性和易于集成于一体的专业 PTC 可复位保险丝，适用于多种应用场合。随着电子产品对安全性要求的不断提高，选择合适的过流保护方案显得尤为关键。凭借其显著的特性和优势，MINISMDC075F/24-2 无疑是一个出色的过流保护解决方案。

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.
