RTT021820FTH 厚膜贴片电阻产品概述

RTT021820FTH是台湾旺诠(RALEC)推出的一款0402封装厚膜贴片电阻,针对中高端电子设备的精密电路需求设计,兼顾阻值精度、功率容量与宽温适应性,是消费电子、工业控制、医疗设备等领域的常用元件。

一、产品基本信息

该电阻属于旺诠常规厚膜贴片电阻系列,型号命名逻辑清晰:

  • RTT02:对应0402封装标识(英制尺寸代码);
  • 182:阻值编码(前两位“18”为有效数字,第三位“2”表示×10²,即18×10²=182Ω);
  • FTH:代表厚膜工艺(Film Thick)及性能规格定义。

品牌为RALEC(旺诠)——全球知名被动元件制造商,以稳定的电阻制造工艺和可靠的产品质量著称,广泛服务于消费电子、工业、汽车等行业。

二、核心性能参数详解

RTT021820FTH的性能参数针对精密应用优化,关键指标及实际意义如下:

  1. 阻值与精度:标称阻值182Ω,精度±1%——高于常规±5%电阻,可满足医疗设备、工业传感器等对阻值一致性要求高的场景,避免因偏差导致的信号失真或测量误差;
  2. 功率容量:1/16W(即62.5mW)——符合0402封装的常规功率上限,适配小电流、低功耗电路(如I=P/R≈0.34mA,V=I×R=50V,与额定电压匹配);
  3. 工作电压:额定50V——非击穿电压,实际使用需结合功率计算,避免过压损坏;
  4. 温度系数(TCR):±100ppm/℃——表示温度每变化1℃,阻值变化约0.0182Ω(182Ω×100ppm),温变下阻值稳定性良好,可适应环境温度波动较大的场景;
  5. 工作温度范围:-55℃~+155℃——覆盖工业级、汽车级部分应用环境(如车载舱内高温、工业现场低温),长期使用可靠性高。

三、封装与物理特性

采用0402贴片封装(英制尺寸:0.04英寸×0.02英寸,公制约1.0mm×0.5mm),具有以下核心优势:

  • 小体积:节省PCB布局空间,适合便携式设备(如智能手机、智能手表)的高密度电路设计;
  • 表面贴装:适配自动化贴装生产线,生产效率高,降低人工成本与焊接误差;
  • 厚膜工艺:相比薄膜电阻成本更低,功率密度适中,兼顾性能与性价比,避免薄膜电阻的高成本劣势,同时优于碳膜电阻的精度与稳定性。

四、可靠性与品牌保障

旺诠作为专业电阻制造商,RTT021820FTH的可靠性体现在:

  • 工艺稳定性:厚膜电阻采用丝网印刷+高温烧结工艺,阻值一致性好,批量生产偏差可控;
  • 环境适应性:通过IEC相关环境测试(如温度循环、湿热测试),抗潮湿、抗振动性能优异,可在恶劣环境下长期工作;
  • 环保合规:符合RoHS、REACH等国际环保标准,不含铅、镉等有害物质,适配绿色电子产品设计需求。

五、典型应用领域

RTT021820FTH的性能适配多场景需求,常见应用包括:

  1. 消费电子:智能手机、平板的信号滤波电路、电源管理模块的分压电阻;
  2. 工业控制:PLC(可编程逻辑控制器)的输入输出接口电阻、传感器信号调理电路;
  3. 医疗设备:血压计、血糖仪的精密测量电路(依赖±1%精度保证测量准确性);
  4. 汽车电子:车载显示屏的背光控制电路、车身传感器的辅助电阻(适配-40℃~+85℃的常规车载环境);
  5. 通信设备:路由器、基站的射频辅助电路、电源模块的限流电阻。

总结

RTT021820FTH是一款高性价比的精密厚膜贴片电阻,通过±1%精度、宽温范围与0402小封装的组合,平衡了性能与成本,是旺诠针对中高端电子设备推出的成熟产品。其可靠的品牌保障与广泛的应用适配性,使其成为电子设计中常用的电阻选型之一。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
