0157010.DR 产品概述 — Littelfuse 贴片式陶瓷快熔保险丝(含座)

一、产品简介

0157010.DR 为 Littelfuse(美国力特)出品的贴片式快熔保险丝组件,属于 Very Fast Acting(极快熔断)类别。器件为陶瓷本体并带保险丝座(SMD clip),封装尺寸为 6.5 × 3.7 × 3.9 mm,适用于要求快速切断故障电流的电路保护场合。器件以盘带(T/R)形式供货,便于自动化贴片生产与装配。

二、主要电气与机械参数

  • 类型:贴片式保险丝(含保险丝座)
  • 额定电流:10 A
  • 额定电压(AC):125 V(额定电压:125 V)
  • 熔断特性:Very Fast Acting(极快熔断)
  • 熔断能量(I2t):26.46 A^2·s(典型值)
  • 最大分断能力:50 A
  • 工作温度范围:-55 ℃ ~ +125 ℃
  • 尺寸(L×W×H):6.5 × 3.7 × 3.9 mm
  • 本体材料:陶瓷(高温与冲击耐受性良好)
  • 封装:SMD,盘带(T/R)

三、关键特性与优势

  • 快速动作:Very Fast Acting 特性可在短时间内切断突发过流,保护下游元器件免受瞬态过电流损害。
  • 陶瓷本体:对高温、热冲击和机械冲击有较好耐受性,适合苛刻环境。
  • 紧凑封装:6.5×3.7×3.9 mm 的 SMD 形式节省 PCB 面积,兼容自动贴装流程。
  • 含座设计:带保险丝座便于更换与维护,提高现场可服务性(视系统设计而定)。
  • 可靠的分断能力:50 A 的分断能力能有效切断常见短路电流,提升保护可靠性。

四、典型应用场景

  • 开关电源与适配器的过流保护
  • 工业控制模块与测试设备的回路保护
  • 通信设备与机箱内部电源防护
  • 电池管理与充电系统(需结合实际浪涌/启动电流评估)
    (注:由于为快熔型,不适合需要承受大启动电流或浪涌充许的应用,选型时请根据实际浪涌/闭塞特性评估是否需使用慢熔型或延时型保险丝。)

五、安装、封装与生产注意事项

  • 该产品以 SMD 盘带(T/R)供货,适配自动化贴片与装配线。
  • 虽为 SMD 形式,具体回流焊兼容性应参考厂家焊接说明或样品测试;如果使用保险丝座,焊接工艺需匹配座体材料与焊盘设计。
  • 使用时需关注环境温度对允许电流的影响,高温工况下建议按厂家曲线进行降额使用以保证可靠性。

六、可靠性与选型提示

  • 工作温度范围宽(-55 ℃ ~ +125 ℃),适合多种工业环境。
  • 熔断能量(I2t)与断开能力为选型时的重要参数:I2t = 26.46 A^2·s(典型)可用于配合上游电路的能量预算与选择。
  • 在有较大浪涌或启动电流的应用中,应确认是否会导致误熔断,必要时选择延时或更高额定电流的型号。

七、包装与订购信息

  • 品牌:Littelfuse(力特)
  • 型号:0157010.DR
  • 供货形式:盘带(T/R),便于 SMT 线自动化取料与贴装。
  • 采购与库存:建议向授权代理或力特官方渠道查询最新库存与详细数据表(Datasheet)以获取完整的电流-时间特性曲线与焊接工艺建议。

八、使用建议与注意事项

  • 选型时参考实际工作电流、允许电压、最大可能短路电流和环境温度,按厂方曲线做热降额。
  • 快熔保险丝适用于保护敏感电子元件免受快速过流损害,但对长期过载或频繁浪涌需谨慎选用。
  • 如需在关键安全或法规约束较强的场合使用,建议查验对应认证与测试报告(如有),并与力特技术支持确认。

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
