2016L300/16MR 产品概述
概述
2016L300/16MR 是由美国力特（Littelfuse）生产的一款聚合物 PTC 自恢复保险丝。该器件是一种表面贴装型保险丝，封装规格为 2016 (5041 公制)，具有凹陷设计。其主要功能是保护电路免受过流条件的损害，同时具备自恢复功能，这意味着一旦故障解除，保险丝会自动恢复到正常工作状态，从而避免了传统熔断保险丝需要更换的问题。
主要参数
- 工作温度范围：-40°C ~ 85°C
- 材料类型：聚合物
- 最大电压：16V
- 最大电流：40A
- 保持电流：3A
- 跳断电流（It）：5A
- 最大动作时间：10s
- 初始电阻值（Ri）：最小 15mΩ
- 跳断电阻值（R1）：最大 48mΩ
- 封装尺寸：0.200" x 0.160"（5.08mm x 4.07mm）
- 厚度：最大 0.045"（1.15mm）
功能与工作原理
聚合物 PTC（正温度系数）自恢复保险丝的工作原理基于聚合物材料的特性。当流经保险丝的电流超过设定的跳断电流时，聚合物的电阻会迅速上升，限制电流的继续流动，从而保护后续电路。在过流发生后，保险丝在超过最大动作时间（10秒）后，会重新恢复其正常状态，允许电流再次流动。因此，这种保险丝特别适合用于需要频繁切换和自恢复的应用场景。
应用场景
2016L300/16MR 广泛应用于各种电子设备中，包括：
- 消费电子产品：例如智能手机、平板电脑、笔记本电脑、电视等。
- 工业设备：如传感器、变频器、自动化设备等，尤其适合需要过流保护的电路。
- 汽车电子：用于保护汽车内的电子系统和配件，确保在电路异常状况下设备正常运行。
- 电源管理系统：如交换电源、充电站等，确保能有效管理和防止过流损耗。
设计与制造优势
力特在设计和制造该保险丝时，采用了高标准的生产工艺和材料，确保产品的可靠性和耐用性。其低初始电阻值（15mΩ）意味着在正常工作状态下能有效减少功耗与热量生成，而跳断后最大电阻（48mΩ）也展现出其在故障状态下的有效隔离能力。这些特性使得 2016L300/16MR 在各类应用中具备出色的性能。
结论
2016L300/16MR 自恢复保险丝凭借其出色的电气性能、广泛的应用范围和方便的安装方式，成为了许多电子设计师和工程师的优选。无论是用于保护高端电子产品，还是在工业和汽车应用中，2016L300/16MR 都能够提供可靠的过流保护，是稳健电路设计的重要组成部分。选择 2016L300/16MR，将为您的产品带来更高的安全性和可靠性。

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.
