RTT0282R0FTH是台湾旺诠(RALEC)推出的0402封装厚膜贴片电阻,属于小型化精密电阻范畴。其核心定位是满足高密度PCB设计中对小尺寸、稳定精度及宽温适应性的需求,适用于多类电子设备的信号调节、分压、限流等基础电路场景。产品以82Ω标准阻值、±1%精度为核心参数,兼顾成本与性能平衡,是消费电子、工业控制等领域的常用无源器件。
产品标称阻值为82Ω,精度等级达**±1%**,属于常规精密级电阻范畴。该精度可满足多数电子电路的信号匹配需求(如模拟信号调理、电压分压),避免因阻值偏差导致的电路性能波动(例如10V分压电路中,±1%偏差仅带来0.1V的输出误差)。
采用0402标准贴片封装(英制尺寸,对应公制约1.0mm×0.5mm),符合IPC-J-STD-001等电子组装标准,适配自动化贴装生产线(SMT),可有效降低PCB空间占用(相比0603封装节省约60%面积),适合高密度集成设计。
基于厚膜丝网印刷烧结工艺制造,相比薄膜电阻具有成本更低、抗浪涌能力更强的特点(可承受10倍额定功率的短时间浪涌);其电阻膜层与氧化铝陶瓷基板结合牢固,耐机械应力性能优于部分薄膜电阻,适合批量生产与应用。
RTT0282R0FTH因尺寸小、精度稳定、宽温适应性强,广泛应用于以下场景:
厚膜电阻的结构特性使其具备较好的抗老化能力:在125℃环境下长期工作(1000小时),阻值漂移率≤±0.5%;0402封装的焊接可靠性符合SMT工艺标准,可通过回流焊(峰值温度245℃)、波峰焊等常规工艺实现可靠连接。
产品符合RoHS 2.0(无铅、无镉、无汞等有害物质)及REACH法规要求,适配全球电子市场的环保准入标准,降低终端产品的合规风险。
旺诠(RALEC)作为台湾知名无源器件制造商,拥有30余年电阻生产经验,产品通过ISO 9001、IATF 16949(汽车级)等认证,批量一致性好(同批次阻值偏差≤±0.2%),供应链稳定性强。RTT0282R0FTH延续品牌的全流程品质管控体系(从原材料筛选到成品测试),可满足电子厂商对无源器件的可靠性需求,降低采购与生产风险。
该产品凭借小尺寸、稳定精度及宽温适应性,成为多领域电子设计的优选无源器件,可有效平衡性能与成本,适配不同场景的集成需求。

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.
