SMD0805-100 自恢复保险丝（SMD0805-100）产品概述
一、产品简介
SMD0805-100 是台湾陆海出品的一款 0805 封装自恢复保险丝（PTC resettable fuse），适用于低压过流保护场合。产品耐压 6V，常态保持电流 1A，具有自动断开并在故障解除后恢复功能，适合对短路或过流具有反复触发可能的电子设备。
二、主要参数
- 型号：SMD0805-100（0805 封装）
- 品牌：台湾陆海
- 额定耐压（Vmax）：6V
- 最大承受瞬时电流（Imax）：100A
- 保持电流（Ihold）：1A
- 跳闸电流（Itrip）：1.95A
- 功耗（Pd）：600mW
- 初始态阻值（Rmin）：60mΩ
- 跳断后阻值（R1max）：230mΩ
- 动作时间（典型）：8s
- 工作温度：-40℃ ~ +85℃
三、特点与优势
- 小型 0805 表面贴装封装，适合高密度 PCB 布局。
- 自恢复功能：过流时自动升阻限流，故障解除后电阻恢复，免替换。
- 高瞬时承受能力（Imax 100A），能承受短时间大浪涌电流。
- 低初始电阻（60mΩ），对正常工作电路压降影响小。
- 宽工作温度范围，可靠性适合一般民用与工业类电子设备。
四、典型应用
适用于手机配件、便携设备、电源管理模块、USB 供电线路、汽车电子（非关键安全回路）、家用电器小功率板卡等需要过流保护且要求可恢复的场合。
五、使用与注意事项
- 使用时不得超过额定耐压 6V，设计时宜留有余量以避免误动作。
- 环境温度对触发电流有影响，高温会降低 Itrip，建议在设计中考虑热退化并做适当降额。
- 贴装工艺应遵循常规 SMD 规范，避免长时间超温回流或机械应力；清洗后确保无腐蚀性残留物。
- 故障排查时请确认是否存在持续性过流或短路故障，频繁触发会影响元件寿命。
六、可靠性与测试建议
建议在样机阶段做温升、浪涌和重复触发试验，验证在目标应用下的动作时间与恢复特性；进行焊接可靠性和高低温循环测试以确认封装与材料稳定性。总体上 SMD0805-100 在空间受限且需自动恢复保护的电路中提供经济且可靠的解决方案。

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.
