RL13FTNR100 产品概述
一、产品简介
RL13FTNR100 是大毅科技（Dayi Technology）推出的一款高稳定性金属膜贴片电阻，阻值为 100 mΩ（0.1 Ω），公差 ±1%，额定功率 500 mW，温度系数（TCR）±200 ppm/℃，封装为 1210（贴片）。该器件以金属膜材料工艺为基础，兼顾低阻值与良好精度，适合对小阻值、高精度和良好热稳定性有要求的场合。
二、主要特性
- 低阻值：100 mΩ，适合电流采样与分流应用
- 高精度：±1% 零件可直接用于精确测量回路
- 中等功率：0.5 W，满足中小电流能量耗散需求
- 良好温漂：TCR ±200 ppm/℃，热稳定性可靠
- 贴片封装：1210 尺寸，便于 PCB 自动化贴装与批量生产
三、典型电气参数
- 阻值：100 mΩ（0.10 Ω）
- 阻值公差：±1%
- 额定功率：500 mW（环境与散热条件影响功率承受能力，实际使用请参考厂方曲线）
- 温度系数（TCR）：±200 ppm/℃
- 封装/安装方式：1210 / SMD（贴片）
四、典型应用场景
- 电流检测与分流：用于低压大电流测量的采样电阻
- 电源管理：开关电源、线性稳压器中电流反馈与限流检测
- 电池管理系统（BMS）：电池充放电电流采样
- 工业与消费类电子：电流监测、保护电路、功率测量前端
五、封装与焊接建议
1210 贴片封装适配自动贴装与回流焊流程。建议按行业标准回流曲线（如 J-STD-020）进行焊接，避免超温或长时间高温暴露。为保证长期稳定性，应注意 PCB 散热设计，避免将器件置于热源直下并采取合适焊盘和铜箔尺寸以优化热阻。
六、可靠性与使用注意
- 热降额：在高温环境下应采取功率降额策略，确保不超过额定功率。
- 机械应力：贴片器件对机械冲击与弯曲敏感，PCB 处理与组装需避免应力集中。
- 长期稳定性：虽然金属膜电阻具有良好稳定性，极端潮湿、腐蚀性环境或长期过载会影响性能，建议依据应用环境选择封装保护或涂覆工艺。
- 规格确认：在关键应用中，请参照大毅科技正式数据手册获取详细的电气特性曲线与环境规范。
七、采购与替代
产品型号：RL13FTNR100，品牌：大毅科技。常见包装形式为卷带（Reel），具体最小包装量与交期请联系供应商或代理商。若需更低阻值、更高功率或更严格 TCR 可考虑其它封装或合金合金膜分流器件，建议与供应方讨论替代型号以满足特殊设计要求。

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.
