RTT06470JTP 贴片厚膜电阻产品概述

一、产品基本信息定位

RTT06470JTP是旺诠(RALEC)推出的一款1206封装贴片厚膜电阻,属于通用型电阻范畴,专为小型化、宽温环境下的电路设计需求打造。该产品以厚膜工艺为核心,结合贴片封装的紧凑尺寸,适配各类对空间要求较高的电子设备,是消费电子、工业控制等领域的常规选型之一。

二、核心参数详细解析

1. 阻值与精度

标称阻值47Ω,精度±5%,实际阻值范围为44.65Ω~49.35Ω,满足大多数常规电路(如分压、限流、信号匹配)的精度需求,无需额外高精度电阻的成本投入。

2. 功率与电压额定值

  • 最大功耗250mW:实际应用中需注意电阻两端电压与电流的乘积不超过该值(例如,工作电压10V时,最大允许电流为25mA),避免过载烧毁。
  • 最大工作电压150V:为安全工作的电压上限,需结合电路实际电压环境选型。

3. 温度特性

  • 温度系数±100ppm/℃:温度每变化1℃,阻值变化量为47Ω×100×10⁻⁶=±4.7mΩ,阻值稳定性符合常规电路要求。
  • 工作温度范围-55℃~+155℃:覆盖工业级宽温环境(如户外设备、汽车辅助电路),无需额外散热或温度补偿。

三、封装与工艺特性

1. 封装规格

1206封装(英制:0.12英寸×0.06英寸;公制:3.2mm×1.6mm),属于贴片电阻中小尺寸,适配高密度PCB布局,可有效节省电路板空间,适合便携式设备或小型化模块设计。

2. 厚膜工艺优势

采用丝网印刷厚膜电阻浆料+氧化铝陶瓷基片高温烧结工艺:

  • 成本低于薄膜电阻,适合批量应用;
  • 抗浪涌能力强,长期阻值漂移小(优于绕线电阻的紧凑性);
  • 耐温性优异,与宽温工作范围匹配。

四、典型应用场景

1. 消费电子

  • 智能手机/平板:电源管理电路限流、音频信号分压、LED背光驱动限流;
  • 智能家居设备:传感器接口电路分压、控制模块信号匹配。

2. 工业控制

  • PLC(可编程逻辑控制器):输入输出接口限流、传感器信号调理;
  • 工业传感器:温度/压力传感器偏置电路(依赖宽温稳定性)。

3. 汽车电子

  • 车载充电器:辅助电路限流、电压分压;
  • 仪表盘:背光电路限流、指示灯偏置(适配汽车级温度环境)。

4. 通信设备

  • 基站射频模块:偏置电阻;
  • 路由器/交换机:LED指示电路限流、数字电路信号匹配。

五、品牌与可靠性说明

旺诠(RALEC)作为专业电阻制造商,其产品符合IEC 60115、JIS C 5201等国际标准,具备完善的质量管控体系:

  • 厚膜工艺确保长期阻值稳定性(1000小时老化后漂移<0.5%);
  • 抗振动(符合MIL-STD-202振动测试)、耐湿度性能优异;
  • 批量生产一致性好,降低终端产品售后维护成本。

总结

RTT06470JTP以紧凑的1206封装、宽温工作范围、常规精度与合理功耗,成为消费电子、工业控制等领域通用电阻的高性价比选型,可满足大多数非高精度电路的设计需求,同时兼顾可靠性与成本控制。

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
