WR06X2700FTL 片式厚膜电阻产品概述

一、产品基本定位与核心身份

WR06X2700FTL是华新科(Walsin)推出的SMD通用型片式厚膜电阻,采用0603英制封装(对应1608公制尺寸),核心参数聚焦“小型化+平衡精度/功率”,适配对空间、稳定性要求较高的电子电路设计。其型号编码清晰对应关键性能:WR代表厚膜电阻系列,06对应封装尺寸,X为功率标识,2700表示270Ω(后两位为精度码),FTL为精度与包装标识。

二、核心电气参数详解

该电阻的参数设计兼顾实用性与稳定性,具体解读如下:

1. 阻值与精度

标称阻值270Ω,精度等级±1%——属于厚膜电阻的常规偏高精度范围,可满足大多数信号调理、分压限流电路的偏差要求(无需额外校准即可实现稳定功能)。例如,在音频放大偏置电路中,±1%精度可避免信号失真;在电源分压电路中,能保证输出电压的一致性。

2. 功率与电压容量

  • 额定功率100mW(0.1W):适配小电流、低功耗场景(如5V电源下,最大允许电流约18.5mA,功率≈0.0925W,接近额定值);
  • 额定工作电压75V:可避免低压电路中的击穿风险,适配部分中低压信号链路(如传感器信号采集的参考电压电路)。

3. 温度系数与工作范围

  • 温度系数±100ppm/℃:表示每升高1℃,阻值变化为标称值的百万分之一百。例如,环境温度从25℃升至125℃(变化100℃),阻值变化量仅2.7Ω(变化率1%),符合工业级温度稳定性要求;
  • 工作温度-55℃~+155℃:覆盖车载冬季低温、电子设备内部高温等极端场景,无需额外温度补偿。

三、封装与工艺特性

1. 小型化封装

0603英制封装尺寸为1.6mm×0.8mm×0.45mm(公制1608),属于SMD最小实用封装之一,可实现高密度贴装(每平方厘米可贴装约400个),适配手机、可穿戴设备等对空间要求严格的产品。

2. 厚膜工艺优势

采用陶瓷基底+厚膜印刷技术制造:

  • 成本低于薄膜电阻,适合批量应用;
  • 抗机械应力能力强,可承受焊接与使用中的轻微振动;
  • 焊接兼容性好,适配回流焊、波峰焊等自动化生产工艺(焊接温度需符合SMD标准)。

四、典型应用场景

作为通用型电阻,该产品广泛覆盖以下领域:

  1. 消费电子:智能手机、智能手表的音频偏置、触控分压电路;
  2. 工业控制:小型PLC模块的传感器信号采集、电机驱动限流;
  3. 汽车电子(辅助电路):车载中控小功率电路、胎压监测信号链路(适配-55℃低温);
  4. 通信设备:物联网网关的阻抗匹配、电源管理模块限流。

五、可靠性与环境适应性

  1. 温度循环稳定性:经-55℃~+155℃循环100次测试后,阻值变化≤1%,性能无明显衰减;
  2. 耐候性:陶瓷基底与封装结构抗潮湿、抗盐雾,可适应沿海地区等恶劣环境;
  3. 焊接可靠性:焊点强度符合行业标准,可承受运输中的振动冲击。

六、使用注意事项

  1. 功率降额:实际功率建议不超过额定值的80%(80mW),环境温度每升高1℃,降额系数约0.004(如125℃时额定功率约60mW);
  2. 电压限制:工作电压不得超过75V,防止击穿;
  3. 焊接工艺:回流焊峰值温度≤245℃(时间≤10秒),波峰焊温度≤260℃(时间≤5秒);
  4. 存放要求:未焊接电阻存放在常温干燥环境(15~35℃,湿度≤60%),存放期≤12个月。

总结

WR06X2700FTL通过平衡小型化、精度、功率与成本,成为通用电子电路的优选元件,其工业级温度范围与可靠工艺,可满足消费电子、工业控制等多领域的稳定应用需求。

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.
