RTT013003FTH是台湾旺诠(RALEC)推出的一款0201封装贴片厚膜电阻,针对小型化、高精度电子设备的需求设计,核心参数覆盖300kΩ阻值、±1%精度、50mW功率等,兼具宽温适应性与可靠性,适用于消费电子、工业控制、汽车电子等多场景。
该电阻属于旺诠厚膜电阻系列中的小功率高精度型号,以0201超小型封装为核心,主打“高密度集成+稳定性能”,填补了小尺寸电路中对300kΩ精密阻值的需求缺口。不同于普通碳膜电阻,厚膜工艺赋予其更好的长期稳定性与抗环境干扰能力,是便携式设备、工业传感器模块等场景的实用选择。
RTT013003FTH的电气参数均经过严格测试,核心指标的实际意义可结合应用场景理解:
采用英制0201封装,尺寸为0.60mm(长)×0.30mm(宽)×0.23mm(厚),是贴片电阻中的超小型封装,适合高密度PCB设计(如智能手机主板、可穿戴设备的微型电路,可在1cm²面积内集成数十个该电阻)。
旺诠采用丝网印刷厚膜工艺:通过在氧化铝陶瓷基片上印刷钌基电阻浆料,经高温烧结形成电阻层,再覆盖保护釉层。该工艺的优势在于:
RTT013003FTH的参数特性使其适配多类场景:
该电阻通过多项可靠性测试,符合IEC 60115-1(固定电阻器通用标准):
此外,厚膜电阻的陶瓷基片具有低膨胀系数,可减少温度变化导致的机械应力,进一步提升长期可靠性(实际应用中,该电阻在车载场景下的平均寿命超过5年)。
总结:RTT013003FTH以超小型封装、高精度、宽温适应性为核心优势,是旺诠针对中高端小功率电路设计的实用型厚膜电阻,可满足多场景下的稳定运行需求,同时兼顾成本与可靠性。

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.
