2920L500/16MR 产品概述
2920L500/16MR 是由美国力特（Littelfuse）公司制造的一款聚合物正温度系数 (PTC) 自恢复保险丝，专为电气保护而设计，广泛应用于各类电子设备中，尤其适用于需要过流保护的场合。该产品的工作电压最高可达16V，最大电流可达到40A，能够有效地保护电路免受过载和短路的损害。其独特的自恢复特性使得在断电后，设备可自动恢复正常工作状态，避免了传统保险丝需要更换的不便。
产品特点
工作温度范围: 该保险丝的工作温度范围为-40°C至85°C，使其适合在各种环境条件下使用。无论是在严寒的冬季，还是在炎热的夏季，2920L500/16MR均能保持稳定性能。
电气特性:
- 最大电压: 16V
- 最大电流: 40A
- 保持电流: 5A
- 跳断电流: 10A
- 初始电阻值: 最小值为5mΩ，确保在正常情况下的电流传导效率非常高。
- 跳断电阻值: 最大25mΩ，保证在过载时的保护效果。
动作时间: 2920L500/16MR 的最大动作时间为5秒，意味着在达到跳断电流的情况下，该保险丝将在短时间内断开电流，从而有效保护后续电路组件。
表面贴装型设计: 产品采用表面贴装技术（SMD），便于集成到现代电路板设计中，节省空间并简化生产工艺。其尺寸为0.289"长 x 0.202"宽（7.35mm x 5.12mm），厚度最大为0.063"（1.60mm），适合多种小型设备的设计需求。
聚合物材料: 该保险丝使用的聚合物材料具有优良的热稳定性和电气性能，能够承受高温并在多次过流后不失效，增加元器件的可靠性。
应用场景
2920L500/16MR 适合于各种需要电流保护的电子设备和电路，典型应用包括但不限于：
- 消费电子产品: 手机、平板电脑、笔记本电脑等。
- 家用电器: 适用于冰箱、微波炉等电器的电路保护。
- 工业设备: 可用于电动工具和机电一体化设备中，以防止过载情况。
- 汽车电子: 在电动汽车和传统汽车中，为电气系统提供稳定的保护。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
