1210L035YR 聚合物重置保险丝产品概述

产品简介

1210L035YR是由美国力特(Littelfuse)公司制造的一款高性能聚合物重置保险丝,广泛应用于保护电路免受过载和短路的风险。该产品以其优越的电气性能及可靠性,在电子元器件领域中得到了广泛认可。作为一种表面贴装型元器件(SMD),1210L035YR可以方便地集成到各种电子设备中,特别是在空间受限或需要高密度布局的应用场合。

基础参数

  • 类型: 聚合物
  • 电压 - 最大值: 6V
  • 电流 - 最大值: 100A
  • 电流 - 保持 (Ih)(最大值): 350mA
  • 电流 - 跳断 (It): 700mA
  • 跳断时间: 200ms
  • 电阻 - 初始 (Ri)(最小值): 320 mΩ
  • 电阻 - 跳断后 (R1)(最大值): 1.3 Ω
  • 工作温度: -40°C ~ 85°C
  • 安装类型: 表面贴装型
  • 封装/外壳: 1210(3225 公制),凹陷
  • 尺寸: 0.127" 长 x 0.102" 宽(3.22mm x 2.58mm)
  • 厚度(最大值): 0.033"(0.85mm)

工作原理

PTC(正温度系数)重置保险丝的工作原理基于聚合物材料在特定条件下电阻的急剧变化。当电流超过设定的跳断电流(It)时,保险丝的电阻会迅速增加,从而限制电流,保护负载设备不受过热或损坏的影响。1210L035YR在正常工作时保持较低的电阻(Ri),能够有效传导电流;而在跳断后,电阻会上升到较高值,显著降低电流流动,防止可能的设备故障。

应用场景

1210L035YR的优越性能使其适用于多种应用领域,包括但不限于:

  • 消费电子: 电视、音响、智能手机等设备的过载保护。
  • 工业设备: 电机驱动、传感器和控制器的保护,确保设备的稳定运行。
  • 通讯设备: 电源供应系统及信号线路的过流保护,保障系统的正常工作。
  • 汽车电子: 电气系统的保护,防止过流对电路及零部件的损害。

设计优点

  • 紧凑的封装设计: 1210L035YR的1210(3225公制)表面贴装封装允许高密度布线,适合空间有限的设计需求。
  • 高耐温性能: 工作温度范围广(-40°C ~ 85°C),确保产品在极端环境下也能稳定工作。
  • 快速响应时间: 本产品的跳断时间为200ms,能够迅速响应电流异常,及时保护负载。
  • 可重置特性: 一旦过载条件解除,保险丝会自动复位,用户无需更换,降低了维护成本。

注意事项

在使用1210L035YR重置保险丝时,应注意以下几点:

  1. 确保电源电压不超过最大额定电压6V。
  2. 考虑环境温度对于产品性能的影响,避免在超出工作温度范围的情况下使用。
  3. 设计电路时应确保电流始终控制在保持电流(Ih=350mA)以下,以确保保险丝正常工作。

结论

综上所述,1210L035YR是一款具有优良电气性能和出色可靠性的聚合物重置保险丝,适用于多种电子产品和系统,是确保设备安全运行的重要元器件。其快速响应、可重置的特性使其成为众多工程师和制造商的理想选择,为现代电子设备的安全提供了有力保障。无论是在消费电子产品、工业控制设备,还是汽车电子领域,1210L035YR都能发挥其重要作用,为设计和应用带来更高的安全性和可靠性。

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
