引言
Littelfuse Inc. 是一家全球领先的电路保护和电气连接解决方案提供商,以其高品质的电子元器件而闻名。0452008.MRL 属于 NANO²® 452 系列,是一款经过精心设计的表面贴装型保险丝。其优越的电气性能和可靠性使其成为现代电子设备中不可或缺的重要组件之一。
基本特性
0452008.MRL 采用卷带(TR)包装,便于自动化生产线的贴装和使用。这款保险丝的零件状态为“在售”,确认了其持续的可用性。该产品的安装类型为表面贴装(SMD),适用于各种空间有限的应用场景,能够在小型电子设备中有效使用。此外,该保险丝专为板安装设计,排除了需要管筒式的安装方式,进一步提高了设计灵活性。
电气性能
该保险丝的额定电流为 8 A,能够有效保护电路,防止由于过电流造成的损坏。其额定电压为 AC 72 V 和 DC 60 V,适用于多种电压应用场合。0452008.MRL 的响应时间为慢速熔断,这意味着在过载情况下,其熔断特性可防止瞬态电流造成的电路损坏,适合那些对瞬态电流较为敏感的应用。
一个重要的参数是不同额定电压时的分断能力为 50A,表明该保险丝能够在特定条件下切断高达 50 安培的短路电流,确保了电路中其他组件的安全运行。其融断 I²t 值为 137.34,这一指标可用于评估保险丝在过电流条件下所能承受的能量,以确保不会因突发的短路而损坏。
机械与环境特性
0452008.MRL 的封装形式为 2-SMD 方形端块,尺寸为 0.240" 长 x 0.106" 宽 x 0.106" 高(6.10mm x 2.69mm x 2.69mm),使其可以在紧凑的空间中占据较少的物理位置。这对于现代电子设计,尤其是便携式或空间受限的设备至关重要。
保险丝的工作温度范围为 -55°C 到 125°C,能够在极端的环境条件下可靠工作。这一广泛的温度范围使得 0452008.MRL 可用于工业、汽车及消费电子等多种应用场景中,不必担心由于温度变化导致的失效风险。
认证与符合性
0452008.MRL 获得了 CSA 和 UR 认证,确保产品的质量符合国际标准,这为客户提供了额外的信赖。认证的存在不仅确保了产品的安全认证,也说明Littelfuse对产品设计和生产过程中的质量控制持有高度的重视。
应用场景
由于上面提到的优秀性能,0452008.MRL 适用于多种领域的应用。这包括:
总结
Littelfuse 0452008.MRL (NANO²® 452) 保险丝是现代电子设计中高度可靠的电流保护解决方案。它的高分断能力、广泛的工作温度范围以及适应性强的封装设计使其成为各种应用场合的理想选择。无论是在消费电子、工业自动化还是汽车电子领域,该产品都能发挥至关重要的角色,保护电路免受过电流损害,确保设备的长期稳定运行。随着电子产品向小型化和智能化发展,Littelfuse 的 NANO²® 系列将继续引领电路保护技术的发展潮流。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
