一、产品基本信息
RTT06R01JTP是台湾旺诠(RALEC)推出的1206封装贴片超低阻值厚膜电阻,属于该品牌针对低阻值电流检测场景开发的系列产品。采用厚膜工艺制造,兼顾成本控制与基本稳定性,适配自动化贴装生产,广泛应用于电源、工业控制等领域的电流采样环节。
二、核心技术参数
该电阻的关键参数均符合工业级应用标准,具体如下:
三、关键特性分析
超低阻值适配电流检测
10mΩ的低阻值设计,可在电流流过时产生微小压降(如5A电流时压降仅50mV),既减少电路功率损耗,又便于通过运放放大采样电压实现电流监测,是电流检测电路的核心元件之一。
厚膜工艺的成本与性能平衡
厚膜电阻通过丝网印刷、烧结等工艺制造,相比金属膜、合金电阻成本更低,且在-55~+155℃宽温范围内能保持基本阻值稳定性,适合对成本敏感但性能要求适中的场景。
功率与电压的匹配性
333mW额定功率下,结合10mΩ阻值计算,最大允许电流约5.77A((I=\sqrt{P/R}=\sqrt{0.333/0.01}));150V工作电压确保高压电源、驱动电路中不会因电压击穿失效,覆盖更多应用场景。
宽温范围的环境适应性
-55℃至+155℃的工作温度,满足工业设备(变频器、PLC)、部分汽车电子等 harsh 环境需求,无需额外温度补偿即可稳定工作。
1206封装的生产兼容性
1206是贴片电阻主流封装,适配绝大多数自动化贴装设备,生产效率高,且可与同封装元件兼容布局,降低PCB设计难度。

Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
