37201600001 产品概述

一、产品简介

37201600001 为 Littelfuse(美国力特)圆柱头插件慢断(Slow Blow)保险丝,额定电流 0.16A,额定电压 250V,适用于需承受启动浪涌电流但又需在持续过流时保护电路的场合。外壳以聚酰胺66(Polyamide 66)制成,结构紧凑,适配常见插件式 PCB 安装方式。

二、主要参数

  • 类型:圆柱头插件保险丝(Slow Blow / 时间延迟型)
  • 额定电流:160mA(0.16A)
  • 额定电压:250V(可用于交流和额定范围内的直流系统,直流断开能力应参考数据表)
  • 工作温度:-40℃ ~ +85℃
  • 熔断 I2t(熔丝熔断能量):0.1792 A²s
  • 分断能力:35A(最大短路断开能力)
  • 外形尺寸:直径 φ8.5mm × 高度 8mm
  • 插件封装:引脚间距 P = 5.08mm(适配常见 2.54mm 双列或直插座布线)
  • 材料:Polyamide 66(阻燃、耐热)
  • 认证:CCC / CQC / KC / SEMKO / UL / VDE / cULus

三、结构与封装说明

本型号为径向插件(radial)圆柱形保险丝,圆柱头设计便于手工或自动化装配。聚酰胺外壳提供良好机械强度和电绝缘特性,引脚间距 5.08mm 适配市面通用 PCB 布局与保险丝座。慢断丝芯结构允许短时浪涌电流通过而不触发断开。

四、性能特性与适用性

  • 时间延迟特性:对短时启动电流或浪涌有容忍性,适合电机、变压器启动和电源滤波电容充放电场合。
  • 低 I2t 值(0.1792 A²s):表示熔断时释放给下游电路的能量较小,有助于保护后级敏感元件。
  • 分断能力 35A:能在较高短路电流条件下可靠断开,适配多数民用与工业电源环境。
  • 宽温工作范围:-40℃ 至 +85℃,适合多种环境温度条件。

五、典型应用场景

  • 开关电源输入保护与二次侧保护
  • 家电、消费电子中需要抗浪涌且保护过流的电路
  • 通讯设备、电源模块、变压器及电机驱动单元
  • PCB 插件式保险保护替换件与量产装配应用

六、选型与使用建议

  • 若电路存在持续性高温或密闭空间,需参照厂方温度-电流特性曲线对额定电流进行适当降额。
  • 在含有较高直流故障电流的系统中,确认 35A 分断能力是否满足实际短路条件。
  • 选择与本型号匹配的保险丝座或夹持件,确保良好焊接与机械固定,避免振动导致接触不良。
  • 对于关键敏感负载,结合 I2t 值评估保险丝的能量释放是否足以保护后级元器件。

七、认证与品质保障

37201600001 拥有多项国际与区域认证(UL、cULus、VDE、SEMKO、KC、CQC、CCC),并由 Littelfuse 品牌制造,质量与可靠性可满足商业与工业级应用要求。

八、存储与注意事项

存放于干燥、无腐蚀性气体环境,避免阳光直射与高温潮湿;在焊接时控制温度与时间,避免对保险丝外壳及内部丝芯造成热损伤。更换时请使用规格相同或经厂商推荐的替代品。

结论:37201600001 为一款面向通用电源与抗浪涌需求应用的可靠慢断插件保险丝,凭借体积小、认证齐全与良好能量特性,适合批量装配与现场维护替换使用。若需更详尽的时间-电流特性或在特殊环境下的降额曲线,请参考 Littelfuse 官方数据手册或联系当地代理商。

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
