1812L035/60MR 产品概述
概述
1812L035/60MR 是美国力特（Littelfuse）推出的一款正温度系数热敏电阻（PTC），其设计旨在提供高效的过流保护，适用于多种电子应用。该产品采用集成的表面贴装型设计，结合高性能的动态响应能力，为电气设备提供可靠的保护。同时，其紧凑的1812（4532公制）封装使其在各种空间受限的应用场景中得到广泛应用。
主要参数
- 类型: 聚合物
- 最大电压: 60V
- 最大电流: 10A
- 保持电流（Ih）: 350mA
- 跳断电流（It）: 700mA
- 跳断时间: 150ms
- 初始电阻（Ri）: 400 mΩ（最小值）
- 跳断后电阻（R1）: 1.7Ω（最大值）
- 工作温度范围: -40°C 至 85°C
- 封装: 1812（4532公制），凹陷
- 尺寸: 4.55mm x 3.24mm x 1.80mm（长 x 宽 x 厚）
设计与应用
1812L035/60MR 采用聚合物材料，具有良好的温度特性和稳定性。当电流超过设定的跳断电流（700mA）时，PTC 会在大约 150ms 内迅速响应，切断电路，从而防止过流引发的过热和其他潜在的安全隐患。其持久的保持电流（350mA）使其在大多数正常工作条件下保持闭合状态，而不会误操作。
该元件的初始电阻为 400 mΩ，确保在正常工作情况下的低电压降。而跳断后电阻的上限为 1.7Ω，这一设计有助于确保在保护状态下仍能保证一定的电流分流能力，为后续电路恢复提供便利。
1812L035/60MR 的工作温度范围从 -40°C 至 85°C，使其能够在各种恶劣环境下稳定运行。这一特性尤其适用于工业、汽车和消费电子等领域的可靠性要求。
应用场景
该PTC热敏电阻适用于各种电气设备和电路，包括但不限于：
- 电池保护: 在电池管理系统中，1812L035/60MR 可用作防止电池过充、电流过大引起的损坏。
- 温控设备: 在电加热器及其它温控设备中可作为过流保护器件，确保设备在安全操作范围内运行。
- 家电产品: 在冰箱、空调等家用电器中，保障电路安全，降低火灾风险。
- 汽车电子: 在车辆电气系统中，防止由于突发电流过大对敏感设备造成损害。
总结
1812L035/60MR 代表了现代电路保护的先进技术，其优越的性能和可靠的响应能力使其成为各种应用的理想选择。其高达 60V 的电压承受能力与 10A 的电流最大值相结合，确保了其在大多数电气环境下的兼容性和适用性。随着电子设备对安全性和有效性的日益重视，Littelfuse 的这一产品将在多个领域中发挥越来越重要的作用。

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.
