RALEC旺诠RTT02242JTH是一款针对高密度小功率电路设计的0402封装厚膜贴片电阻,属于旺诠常规厚膜电阻系列中的主力产品。型号字符对应核心信息:
该产品聚焦消费电子、工业控制等领域的小信号处理场景,兼顾体积小型化与宽温稳定性,是替代传统插件电阻的高性价比选择。
标称阻值2.4kΩ(2400Ω),精度±5%(J档),符合E24系列电阻的常规精度要求,满足大多数非超高精度电路(如传感器接口、电源反馈)的设计需求。
温度系数(TCR)为±100ppm/℃,即温度每变化1℃,阻值变化量为标称值的±100×10⁻⁶。以25℃为基准:
体积仅1.0mm×0.5mm,比0603封装小约60%,适合智能手机、智能穿戴、小型工业模块等轻薄化PCB设计,有效节省电路板空间。
采用氧化铝陶瓷基片为载体,丝网印刷钌基电阻浆料后高温烧结而成,相比薄膜电阻:
符合SMT(表面贴装技术)标准,可兼容回流焊、波峰焊等常规焊接工艺,适配自动化生产线,提高生产效率。
旺诠针对该产品完成高低温循环测试(-55℃~+155℃,1000次循环),阻值漂移控制在±0.5%以内,功率衰减≤1%,满足工业级长期工作要求。
RALEC旺诠是全球被动元件领域的老牌制造商(成立于1988年),拥有完整的电阻生产产业链,供货稳定(月产能超10亿只),交期可控(常规订单1-2周)。
RTT02242JTH凭借小体积、宽温稳定、低功耗三大核心优势,成为消费电子、工业控制、物联网等领域小信号电路设计的高性价比选择。其厚膜工艺平衡了成本与性能,0402封装适配高密度PCB,是替代传统插件电阻的理想方案。

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.
