SMD2920P150TF 产品概述
一、产品简介
SMD2920P150TF 为 RUILON（瑞隆源）推出的一款表面贴装式过流保护器件，常用作自恢复型聚合物保险（PPTC）用于电路的过流与短路保护。器件体积小巧（封装尺寸 2920），适合贴片回流焊工艺，能在异常电流出现时迅速增阻限流，故障解除后自动恢复导通，便于重复使用和维护。
二、主要参数
- 最大耐压（Vmax）：33 V
- 最大允许电流（Imax）：40 A
- 保持电流（Ihold）：1.5 A（常态下保持导通的最大稳态电流）
- 跳闸电流（Itrip）：3 A（器件进入高阻态时的触发电流）
- 功耗（Pd）：1.5 W（在额定条件下的功率消耗）
- 初始态电阻（Rmin）：35 mΩ
- 跳断后电阻（R1max）：230 mΩ
- 动作时间：约 2 s（达到跳闸状态的典型时间）
- 工作温度范围：-40 ℃ ～ +85 ℃
- 封装尺寸：长度 7.98 mm × 宽度 5.44 mm × 高度 1.3 mm
- 品牌：RUILON（瑞隆源）
- 封装样式：2920 SMD
三、主要特性
- 小体积、低功耗：适配高密度 PCB 设计，初始电阻低，正常工作时压降小。
- 可自恢复：过流后进入高阻态以限制电流，故障消除后电阻恢复，适合反复保护需求。
- 宽工作温度：-40 ℃ 至 +85 ℃，适应工业级与车规级环境（在应用时应考虑温升与散热）。
- 快速响应：典型动作时间约 2 秒，可对持续过流与中等故障快速限流保护。
- 高最大电流能力：短时承受高达 40 A 的能量（选型时注意 Ihold/Itrip 与实际电流峰值的匹配）。
四、典型应用
- 汽车电子（车载控制模块、充电接口、保险电源线）
- 电池管理与便携电源（保护电源输出、充放电回路）
- 开关电源、DC-DC 模块输入/输出保护
- LED 驱动与功率模块的过流保护
- 通信设备与工控设备的电源防护
五、安装与使用注意事项
- 推荐采用与 2920 封装匹配的 PCB 焊盘与回流工艺，避免过长的焊接时间和超温。
- 器件额定值针对稳态和短时条件，遇到瞬时大电流脉冲或短路，应核算能量与热量，必要时并联或配合快速熔断器使用。
- 在高环境温度或紧邻发热元件时，应进行适当降额使用，避免长期接近最大功率 Pd 导致热失效。
- 储存与搬运时避免受潮、受力或划伤，焊接后避免反复多次热循环。
六、订购信息与备注
- 型号：SMD2920P150TF
- 品牌：RUILON（瑞隆源）
- 封装：2920 SMD（适合卷带/盘装 SMT 自动贴装）
- 选型提示：请根据系统正常工作电流（≤ Ihold）与可能的故障电流范围（比较 Itrip、Imax）进行综合选型；对短路清除速度要求高的场合，建议与快速熔断器或保护电路配合使用，以保证安全性与可靠性。若需详细电气特性曲线、典型温升或 PCB 推荐焊盘图，请向供应商索取完整数据手册。

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.
