RTT011R00FTH是台湾旺诠(RALEC)推出的0201封装厚膜贴片电阻,核心参数为1Ω标称阻值、±1%精度、50mW额定功率,属于小功率高密度厚膜电阻范畴。该产品针对小型化、批量化应用场景设计,兼顾成本与基础性能,可满足消费电子、工业控制等领域的常规电路需求,是替代同规格薄膜电阻的高性价比选择。
标称阻值1Ω,精度±1%,符合IEC 60115-1电阻精度等级(F级)。该精度可满足一般电流检测、分压电路的需求(非超精密场景,如医疗设备的高精度采样需升级至±0.1%薄膜电阻)。
-55℃~+125℃,覆盖工业级温度标准(IEC 60068-2-1/2),可适应车载、户外设备等恶劣温度场景。
尺寸约为0.6mm(长)×0.3mm(宽)×0.23mm(厚),是小型化PCB设计的常用封装,每平方厘米可容纳约2000个该电阻,显著提升电路密度。
RALEC是全球知名被动元器件制造商,专注厚膜电阻研发30余年,产品通过ISO 9001、IATF 16949等认证,厚膜电阻的工艺成熟度、一致性在行业内领先,批量供货稳定性高,适合中低端消费电子的大规模生产。
相比薄膜电阻,厚膜电阻采用丝网印刷+烧结工艺,成本降低30%~50%,适合大规模量产;但温度系数、精度略逊于薄膜电阻(薄膜电阻TCR可低至±10ppm/℃)。
0201封装机械强度较低,需避免:
厚膜电阻的玻璃釉涂层耐湿性一般,长期暴露于高湿度(>85%RH)、腐蚀性气体环境可能导致阻值漂移,建议在密封或涂覆( conformal coating)电路中使用。
该产品以高性价比、小封装优势,成为消费电子、工业控制领域常规电路的主流选择,适合对成本敏感但需基础精度的应用场景。

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.
