RTT029310FTH 厚膜贴片电阻产品概述

RTT029310FTH是台湾旺诠(RALEC)推出的0402封装厚膜贴片电阻,针对小型化、低功耗电子电路的高密度贴装需求设计,兼具成本优势与可靠性能,核心参数覆盖阻值、精度、功率等关键指标,广泛适配多领域应用场景。

一、产品定位与核心基础

该电阻属于旺诠厚膜电阻系列的常规精度型号,主打「小体积+稳定性能」平衡:

  • 采用0402小型封装(1.0mm×0.5mm),满足便携式设备、高密度PCB的空间限制;
  • 厚膜工艺确保量产一致性与长期可靠性,适合批量应用;
  • 核心基础参数明确:阻值931Ω(定制化非标准阻值)、精度±1%、额定功率62.5mW,是通用电路的实用选择。

二、关键电气参数与应用关联

1. 阻值与精度

阻值固定为931Ω,精度±1%,允许阻值范围为921.69Ω~940.31Ω,满足大多数信号调理、分压、滤波电路的精度需求(无需高精度薄膜电阻的场景)。

2. 功率与电压

  • 额定功率62.5mW(0.0625W),适合低功耗电路(如传感器信号放大、低功率控制回路);
  • 额定工作电压50V,实际最大电流可通过公式计算:I_max = P/R ≈ 67μA,需注意实际功率不超过额定值。

3. 温度特性

温度系数±100ppm/℃,意味着温度每变化1℃,阻值变化±0.0931Ω。在工作温度范围(-55℃~+155℃)内,总阻值变化最大约±19.55Ω,满足工业级环境下的基本温度稳定性要求。

三、封装与工艺特点

1. 0402封装细节

封装尺寸符合IPC标准(0.04英寸×0.02英寸),兼容主流贴装设备(富士、西门子等),焊接可靠性高(可通过回流焊、波峰焊实现批量贴装,具体工艺需参考旺诠官方datasheet)。

2. 厚膜工艺优势

采用旺诠成熟的厚膜制造工艺:

  • 丝网印刷高精度电阻浆料于氧化铝陶瓷基底;
  • 高温烧结形成致密电阻层,相比薄膜电阻成本更低,且抗冲击、抗振动性能更优,适合户外、工业等耐环境场景。

四、典型应用场景

  1. 便携式电子设备:手机、智能手环、蓝牙耳机的信号调理电路(如麦克风偏置、电池监测分压);
  2. 消费类电子:智能家居设备(温湿度传感器接口)、小型家电控制板(LED驱动辅助电阻);
  3. 工业控制:低功耗传感器模块(压力、流量传感器信号放大回路)、小型PLC输入输出接口;
  4. 汽车电子(基础场景):车载小功率控制电路(仪表盘背光驱动、传感器信号滤波,需结合整车认证);
  5. 通信设备:蓝牙/WiFi模块射频辅助电路、低功耗基站信号处理单元。

五、可靠性与品质保障

  1. 环境适应性:工作温度-55℃+155℃,覆盖工业级(-40℃+85℃)与扩展工业级(-55℃~+125℃)需求;
  2. 长期稳定性:经1000小时高温负荷测试,阻值漂移率通常低于0.5%,适合长期运行设备;
  3. 品牌保障:RALEC(旺诠)为全球知名电阻制造商,产品符合RoHS、REACH环保标准,供货稳定,适合批量采购。

六、选型注意事项

  1. 实际使用功率需低于62.5mW(环境温度>85℃时需进一步降额);
  2. 焊接需遵循0402封装回流焊温度曲线,避免过热导致阻值漂移;
  3. 若需更高温度稳定性(如±50ppm/℃),需考虑薄膜电阻(成本更高)。

RTT029310FTH通过平衡性能与成本,成为小型化电子设备的实用电阻选型,可满足多领域的常规电路需求。

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
