RALEC RTT06R800FTP 厚膜电阻产品概述

一、产品核心参数总览

RALEC RTT06R800FTP是一款1206封装毫欧级厚膜贴片电阻,核心参数平衡了性能与成本,适配中低端电流检测、分压及小型负载场景,关键参数如下:

  • 电阻类型:厚膜贴片电阻(Thick Film Chip Resistor)
  • 标称阻值:800mΩ(毫欧级低阻,区别于常规欧姆级电阻)
  • 精度等级:±1%(常温下阻值偏差不超过标称值的1%)
  • 额定功率:333mW(0.333W,连续工作最大功率限制)
  • 最大工作电压:150V(绝缘耐压限制,需与功率同步满足)
  • 温度系数(TCR):±200ppm/℃(温度每变1℃,阻值变化±200×10⁻⁶)
  • 工作温度范围:-55℃ ~ +155℃(覆盖工业级温宽要求)
  • 封装尺寸:1206(英制代码,对应公制3.2mm×1.6mm,标准贴片封装)
  • 品牌:RALEC(旺诠科技,台湾知名被动元件制造商)

二、封装与工艺特点

2.1 1206标准封装优势

1206封装属于中小尺寸贴片电阻,适配性突出:

  • 高密度贴装:3.2×1.6mm尺寸适合紧凑PCB布局,常见于消费电子、小型电源模块;
  • 通用兼容性:适配主流SMT贴片机、回流焊工艺,无需特殊工具;
  • 机械稳定性:陶瓷基板基底抗振动、抗冲击,满足一般工业应用需求。

2.2 厚膜工艺核心特性

采用厚膜印刷烧结工艺,相比薄膜电阻(精度高、成本高)和绕线电阻(体积大、高频差),具备平衡优势:

  • 成本可控:适合批量应用,性价比高于薄膜电阻;
  • 耐温可靠:烧结工艺使电阻膜与陶瓷基板结合紧密,承受-55℃~+155℃宽温;
  • 阻值覆盖广:可实现毫欧级到兆欧级阻值,此款为800mΩ低阻设计。

三、电气性能关键指标解析

3.1 低阻与精度的适配性

800mΩ毫欧级阻值搭配±1%精度,适合小电流采样场景:

  • 常温阻值偏差为±8mΩ(800mΩ×1%);若用于10A电流检测,电压降为8mV(10A×0.0008Ω),偏差仅±0.08mV,满足一般电流监测需求(如电池充电电流、电源输出电流)。

3.2 功率与电压的限制关系

需同时满足功率(333mW) 和电压(150V) 双重限制:

  • 功率限制:由(I_{max}=\sqrt{P/R})得,最大连续电流≈20.4A(实际需降额);
  • 电压限制:150V为绝缘耐压(防止高压击穿),实际工作电压降远低于此值,因此功率为主要限制。

3.3 温度系数的实际影响

±200ppm/℃的TCR,在温宽内阻值变化需注意:

  • 从25℃升至155℃(温差130℃),阻值变化为20.8mΩ,即范围为800±20.8mΩ;
  • 高精度场景(如医疗仪器)需结合温度补偿,或选择TCR更低的电阻(如±50ppm/℃)。

四、典型应用场景

基于低阻、宽温、小封装特性,RTT06R800FTP适用于:

  1. 电源模块电流检测:DC-DC转换器、AC-DC适配器的输出电流采样;
  2. 小型BMS:移动电源、小型锂电池组的充放电电流监测;
  3. 分压/负载电路:小信号电路的分压(如电压基准分压)、小型设备负载;
  4. 工业控制:PLC、传感器模块的信号调理,适配工业现场温宽;
  5. 消费电子:手机、智能穿戴的电源管理模块,适配高密度PCB。

五、品牌与可靠性说明

RALEC(旺诠科技)是台湾老牌被动元件厂商,产品可靠性突出:

  • 环保认证:通过RoHS、REACH,无铅无卤,适配全球市场;
  • 批量一致性:厚膜工艺成熟,批量生产阻值、TCR偏差稳定;
  • 长期可靠性:经高温老化、振动测试,MTBF满足工业级要求。

六、选型与使用注意事项

  1. 降额使用:
    • 常温(25℃)降额至70%以下(≤233mW);
    • 高温(>100℃)降额至50%以下(≤166mW),避免热失效;
  2. 贴装工艺:
    • 焊盘尺寸符合IPC-7351(长度2.02.2mm,宽度1.21.4mm);
    • 回流焊峰值温度≤245℃,时间≤10s;
  3. 精度适配:
    • 高精度场景(如医疗仪器)建议选±0.1%精度、±50ppm/℃的薄膜电阻;
  4. 电压限制:避免超过150V,防止绝缘击穿。

此款电阻以性价比为核心,适配中低端电流检测及通用电路,是消费电子、小型工业设备的实用选型。

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.
