WR02X33R0FAL 厚膜片式电阻器产品概述

一、产品定位与核心参数

WR02X33R0FAL是华新科(Walsin)推出的小型化厚膜片式固定电阻器,针对高密度贴装、低功耗及中等精度需求设计,核心参数如下:

  • 标称阻值:33Ω
  • 阻值精度:±1%
  • 额定功率:50mW(即1/20W)
  • 最高工作电压:25V
  • 温度系数(TCR):±100ppm/℃
  • 工作温度范围:-55℃至+125℃
  • 封装形式:0201(英制)/0603(公制)

二、封装与尺寸规格

该电阻采用0201封装(英制:0.02英寸×0.01英寸;公制对应0603:0.6mm×0.3mm),是当前表面贴装电阻中尺寸最小的规格之一,具体尺寸(华新科官方):

  • 长度:0.6±0.05mm
  • 宽度:0.3±0.05mm
  • 厚度:0.23±0.03mm
  • 端电极:镍/锡镀层,尺寸0.15±0.05mm(长)×0.3±0.05mm(宽)

小尺寸设计可显著提升电路板空间利用率,适配智能手机、可穿戴设备等对体积要求严苛的产品。

三、电气性能特性

  1. 精度与稳定性:±1%精度满足通用电路的匹配、分压需求,无需额外校准;±100ppm/℃温度系数下,温度每变化1℃阻值漂移仅0.0033Ω,适合信号调理电路。
  2. 功率与电压适配:50mW额定功率适配低功耗场景(如蓝牙模块、传感器节点);25V最高工作电压覆盖3.3V/5V/12V等常见低压电路,安全余量充足。
  3. 高频性能:厚膜工艺使高频(几十MHz~几百MHz)阻值变化≤1%,可用于射频电路的匹配或负载电阻。

四、环境适应性

  • 宽温工作:-55℃~+125℃覆盖工业级(户外传感器、PLC)及部分汽车电子(车载信息娱乐系统)场景;
  • 耐焊接热:可承受260℃回流焊3次,焊接后阻值变化≤0.5%;
  • 耐湿抗腐:环氧树脂封装+镍锡端电极,85℃/85%RH湿度测试1000小时,阻值变化≤1%,端电极无氧化。

五、典型应用场景

  1. 消费电子:智能手机摄像头模组、智能手表心率传感器、蓝牙耳机射频匹配网络;
  2. 工业控制:小型PLC输入输出接口、温度/压力传感器信号调理;
  3. 物联网终端:BLE节点、温湿度监测模块的限流/分压电阻;
  4. 汽车电子:车载导航小型化电路、车身控制模块(BCM)辅助电路(需确认具体车规适配性)。

六、品牌与可靠性

华新科作为全球被动元件龙头,该电阻通过严格可靠性测试:

  • 高温寿命(125℃,1000h):阻值变化≤0.5%;
  • 机械测试:1.5m跌落阻值变化≤0.2%,25mm曲率弯曲合格;
  • 环保认证:符合RoHS 2.0、无卤素(HF)及REACH标准,适配全球市场。

WR02X33R0FAL以小尺寸、高精度、宽温稳定为核心优势,是小型化电子设备的理想电阻选型。

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
