RALEC RTH06R100FTP 厚膜贴片电阻产品概述

一、产品定位与核心参数

RALEC RTH06R100FTP是旺诠针对工业控制、汽车电子、电源管理等场景设计的1206封装厚膜低阻贴片电阻,核心参数精准匹配电流检测、信号调理需求:

  • 阻值:100mΩ(低阻范畴,适合大电流采样)
  • 精度:±1%(满足工业级基本精度要求)
  • 额定功率:500mW
  • 额定工作电压:200V
  • 温度系数(TC):±100ppm/℃
  • 工作温度范围:-55℃~+155℃

二、关键性能指标详解

1. 低阻与功率的匹配性

100mΩ低阻值搭配500mW功率,可支持最大允许电流约70.7A(计算:$I=\sqrt{P/R}=\sqrt{0.5W/0.0001Ω}$),既避免高阻带来的额外功耗,又满足中低功率大电流回路的采样灵敏度需求。

2. 精度与温漂控制

±1%精度覆盖多数工业采样场景(如电源输出监测);±100ppm/℃温度系数意味着:温度变化100℃时,阻值仅漂移±0.01Ω(100mΩ×100ppm×100℃),有效降低温漂对检测结果的干扰。

3. 电气安全与可靠性

200V额定电压远高于常规低阻电阻(≤100V),避免高压场景绝缘击穿;-55℃+155℃宽温区适配工业(-40℃+85℃)、汽车(-40℃~+125℃)等极端环境。

三、封装与工艺特点

1. 1206封装的兼容性

1206封装(3.2mm×1.6mm)是贴片电阻主流标准化封装,兼容自动贴片机(SMT)生产,适合高密度PCB布局(如电源模块、BMS电路板),提升量产效率。

2. 厚膜工艺的优势

采用旺诠成熟厚膜工艺:电阻浆料丝网印刷在氧化铝陶瓷基板上,经高温烧结、电极制作而成,具备:

  • 阻值一致性好(批量偏差小);
  • 耐脉冲能力强(可承受短时间过流冲击);
  • 成本适中(兼顾性能与性价比)。

四、典型应用场景

1. 电源模块电流检测

开关电源、DC-DC转换器的输出电流采样:低阻减少自身功耗,±1%精度满足负载监测准确性,200V电压适配高压电源。

2. 电池管理系统(BMS)

电动车、储能电池的单体/模组电流采样:宽温特性适配充放电温度波动,低阻支持10~50A充电电流精准检测。

3. 工业变频器与伺服系统

电机驱动回路的过流保护采样:200V电压满足高压驱动,500mW功率承受启动瞬间电流冲击,防止设备损坏。

4. 汽车电子传感器

胎压监测、电池传感器的信号调理:符合车规级温度要求,厚膜工艺长期稳定性满足汽车电子可靠性标准。

五、品牌与品质保障

RALEC(旺诠)专注电阻研发30余年,产品通过:

  • ISO9001质量管理体系认证;
  • IATF16949汽车电子行业认证;
  • RoHS/REACH环保标准(无铅封装)。

RTH06R100FTP经高温老化、温度循环、湿度测试等多重验证,批量供货稳定,满足量产需求。

六、选型与使用注意事项

  1. 功率降额:实际电流控制在额定电流80%以内(≈56.6A),避免过负荷导致阻值漂移;
  2. 精度匹配:需更高精度(如±0.1%)可选同系列RTH06R100FHT;
  3. 焊接工艺:回流焊峰值温度240℃~250℃,避免手工焊接过热;
  4. 布局设计:电流检测时串联被测回路,靠近采样点减少线路阻抗影响。

该产品以平衡的性能、成本与可靠性,成为工业与汽车电子领域电流检测的实用选型。

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
