RALEC旺诠RTT02R100FTH厚膜贴片电阻产品概述
一、产品基本定位与核心应用场景
RTT02R100FTH是RALEC旺诠推出的微型低阻厚膜贴片电阻，核心定位为高密度PCB设计中的电流检测、功率取样及信号调理场景。其100mΩ低阻值、±1%精度与0402微型封装，适配以下典型应用：
- 消费电子：智能手机、可穿戴设备的电池管理系统（BMS）电流检测，小型电源适配器的过流保护电路；
- 工业控制：小型PLC模块的电流取样、传感器信号放大电路的基准电阻；
- 汽车电子（辅助场景）：车载充电器、小功率传感器的信号调理（需结合80%降额设计）。
二、关键电气与物理参数解析
该电阻参数针对低阻应用做了针对性优化，核心参数意义明确：
- 阻值与精度：100mΩ（0.1Ω）低阻值+±1%精度，满足中等精度电流检测需求（如BMS中0-20A电流取样误差≤0.2A）；
- 功率与电流能力：额定功率62.5mW，经计算最大允许电流为25A（公式：I=√(P/R)=√(62.5e-3/0.1e-3)=25A），实际应用需按行业标准降额（通常80%），即最大可用电流约20A，适配中小功率电流回路；
- 电压与温度系数：额定工作电压50V（不得超过此值），温度系数±600ppm/℃（每℃阻值变化±0.06mΩ），在-55℃~+155℃范围内，最大阻值变化率约12.6%（温差210℃），适合成本敏感型场景；
- 封装尺寸：0402英制封装（1.0mm×0.5mm×0.3mm），比0603封装体积小60%，适配高密度PCB布局。
三、封装与工艺特性
- 0402微型封装优势：体积紧凑，可有效减少板级空间占用，适合智能手机、蓝牙耳机等小型化产品的高密度布线；
- 厚膜工艺特点：采用丝网印刷+高温烧结工艺制作，相比薄膜电阻成本降低30%-40%，同时具备较好的耐湿性、抗机械冲击性，适配回流焊、波峰焊等标准贴片工艺，良率稳定。
四、环境适应性与可靠性
- 宽温工作范围：-55℃~+155℃覆盖大部分工业、消费电子场景（如高温环境下的电源模块内部），满足极端温度下的稳定工作；
- 环保与认证：符合RoHS 2.0、REACH等全球环保标准，无铅无卤，适配国际市场需求；
- 可靠性验证：经振动（10-2000Hz，1g）、温度循环（-55℃~+155℃，1000次）测试，阻值漂移率≤0.5%，满足长期使用需求。
五、品牌与品质保障
RALEC旺诠是台湾老牌电阻制造商，专注电阻研发30余年，产品覆盖厚膜、薄膜、功率电阻全系列，年产能超100亿只。RTT02R100FTH作为其主流低阻产品，已被华为、小米、台达等厂商应用于终端产品中，品质稳定性经市场验证；同时提供1年质保服务，售后响应及时。
该产品以高性价比、小体积、稳定可靠为核心优势，是低阻电流检测场景的实用选型。

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.
