RTT021003FTH 厚膜贴片电阻产品概述

一、产品基本信息

RTT021003FTH是RALEC(旺诠) 推出的一款小型化厚膜贴片电阻,采用0402封装(英制规格,对应公制1005),属于高精度常规功率级贴片电阻范畴。该产品针对高密度电路设计,兼顾小型化、可靠性与成本效益,广泛适配消费电子、工业控制等多领域应用需求。

二、核心电气性能参数

该电阻的关键电气指标明确且满足常规应用的精度与环境要求:

  • 阻值:100kΩ(固定阻值,无可调设计);
  • 精度:±1%(高于普通±5%精度电阻,适合信号匹配、分压等需要精确阻值的场景);
  • 额定功率:62.5mW(即1/16W,为0402封装贴片电阻的典型功率等级);
  • 工作电压:50V(由功率与阻值推导:(P=U^2/R),50V²/100kΩ=25mW,远低于额定功率,电压裕量充足);
  • 温度系数(TCR):±100ppm/℃(厚膜电阻的典型温系范围,阻值随温度变化稳定,满足多数工况下的精度需求);
  • 工作温度范围:-55℃~+155℃(工业级宽温设计,可适应户外、高低温交替等 harsh 环境)。

三、封装与物理特性

采用0402贴片封装,具备以下特点:

  • 尺寸规格:约1.0mm(长)×0.5mm(宽)×0.3mm(厚),体积小巧,可显著降低电路的空间占用;
  • 焊接兼容性:支持常规SMT工艺(回流焊、波峰焊),焊接温度曲线需符合0402封装的标准参数(通常回流焊峰值温度230-245℃,时间≤10s);
  • 机械可靠性:封装结构紧凑,抗振动、抗冲击性能满足工业级标准(振动频率10-2000Hz,加速度1g;冲击加速度100g),适合便携设备的频繁移动场景。

四、适用应用场景

基于其小型化、宽温、高精度的特性,RTT021003FTH主要适用于以下场景:

  1. 便携电子设备:智能手机、智能手环、蓝牙耳机等便携产品的信号调理电路(如滤波、分压),满足小型化与低功耗需求;
  2. 工业控制电路:PLC模块、传感器接口电路、电机驱动辅助电路,宽温设计适应工业现场的高低温环境;
  3. 消费电子模块:电视、机顶盒、智能家居设备的电源偏置电路、信号放大电路,±1%精度保证信号质量;
  4. 通信设备:路由器、基站射频前端的匹配网络、偏置电路,功率与电压参数满足通信电路的常规需求;
  5. 小型医疗电子:便携式监护仪、血糖仪等设备的内部电路,小型化设计利于设备轻量化。

五、品牌与可靠性说明

RALEC(旺诠)作为专业电阻制造商,其产品具备以下可靠性优势:

  • 工艺成熟:厚膜电阻采用丝网印刷、烧结等成熟工艺,阻值一致性好,长期使用阻值漂移≤0.5%(在额定工况下);
  • 环保合规:符合RoHS 2.0、REACH等国际环保标准,无铅无镉,适配绿色电子产品设计;
  • 批量一致性:批量生产时阻值偏差控制在±1%范围内,适合大规模自动化生产的品质要求;
  • 认证支持:部分批次可提供符合IEC 61039等电阻标准的测试报告,满足工业客户的认证需求。

六、选型与应用注意事项

为保证产品性能与寿命,应用时需注意以下几点:

  1. 功率降额:实际工作功率建议不超过额定功率的70%(即≤43.75mW),避免过热导致阻值漂移或失效;
  2. 电压限制:实际工作电压需≤50V,严禁超过额定电压使用,防止击穿;
  3. 焊接工艺:0402封装体积小,需注意焊接时的锡量控制,避免桥接;回流焊需严格遵循温度曲线,防止过热损坏电阻;
  4. 存储条件:未焊接的电阻需存储在常温(15-35℃)、干燥(相对湿度≤60%)环境中,避免受潮影响焊接性能;
  5. 精度匹配:若应用场景需要更高精度(如±0.1%),需更换金属膜或合金电阻,本产品±1%仅适用于常规精度需求。

以上为RTT021003FTH厚膜贴片电阻的核心概述,可根据具体应用场景进一步确认参数匹配性。

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
