WR12X2400FTL 片式厚膜电阻产品概述

WR12X2400FTL是华新科(Walsin)推出的通用型SMD片式厚膜电阻,采用1206英制(对应3216公制)标准封装,核心参数针对中小功率电路设计,兼具稳定性、成本优势与宽环境适应性,广泛适用于消费电子、工业控制、汽车电子等领域。

一、产品核心参数概览

该电阻的关键技术参数明确,可直接匹配电路设计需求:

  • 电阻类型:厚膜片式电阻(Thick Film Chip Resistor)
  • 标称阻值:240Ω,精度±1%(满足多数工程场景的阻值准确性要求)
  • 额定功率:250mW(25℃环境下的额定功率,温度升高需按降额曲线使用)
  • 最大工作电压:200V(电路中需避免超过此电压,防止击穿损坏)
  • 温度系数(TCR):±100ppm/℃(温度变化时阻值漂移较小,稳定性良好)
  • 工作温度范围:-55℃~+155℃(覆盖工业、汽车等严苛环境的温度需求)
  • 封装规格:1206英制(0.12英寸×0.06英寸)/3216公制(3.2mm×1.6mm),符合行业标准封装尺寸

二、技术特性与应用优势

WR12X2400FTL的设计兼顾性能与实用性,核心优势体现在以下几点:

  1. 阻值精度与稳定性:±1%的精度优于常规±5%电阻,适合需要准确分压、限流的电路(如传感器信号调理、电源反馈回路);±100ppm/℃的温度系数可有效降低温度变化对阻值的影响——例如,温度从25℃升高至125℃(变化100℃),阻值仅变化±2.4Ω,满足多数应用的精度要求。
  2. 功率与电压适配性:250mW额定功率适配中小功率电路(如LED驱动、单片机外围电路);200V最大工作电压可覆盖多数低压直流/交流电路,无需额外串联保护电阻,简化电路设计。
  3. 自动化贴装适配:1206标准SMD封装支持高速自动化贴装,适合批量生产场景,可显著提升PCB组装效率。
  4. 厚膜工艺优势:厚膜电阻采用丝网印刷+烧结工艺,相比薄膜电阻成本更低,同时具备较好的耐过载能力,适合常规工况下的长期稳定使用。

三、典型应用场景

基于参数与特性,WR12X2400FTL的应用覆盖多个领域:

  • 消费电子:手机、平板、智能穿戴设备的电源管理电路(如电池充放电限流)、信号滤波电路;
  • 工业控制:小型PLC的输入输出接口、传感器信号调理电路(如温度传感器的分压网络);
  • 汽车电子:车载辅助电路(如仪表盘背光驱动、传感器信号处理),其-55℃~+155℃的工作温度范围可适应汽车发动机舱等高温环境;
  • 通信设备:基站、路由器的小信号处理电路(如射频前端的匹配网络)。

四、环境适应性与品质保障

  • 宽温域稳定性:工作温度范围覆盖低温(-55℃)与高温(+155℃),可满足户外设备、工业现场等严苛环境的温度需求;
  • 华新科品质:作为全球知名被动元件厂商,华新科的厚膜电阻生产工艺成熟,产品一致性好,符合RoHS、REACH等环保标准,可满足国内外客户的合规要求;
  • 降额使用建议:实际应用中需遵循功率降额原则——例如,在125℃环境下,额定功率需降至约160mW(具体可参考华新科官方 datasheet),以保障长期可靠性。

五、总结

WR12X2400FTL是一款高性价比的通用型SMD厚膜电阻,核心参数匹配多数中小功率电路的设计需求,宽温域、稳定的阻值特性及标准封装使其成为消费电子、工业控制等领域的优选元件。如需进一步了解降额曲线、测试数据等细节,可参考华新科官方发布的产品 datasheet。

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.
