WR04X1000FTL 厚膜电阻产品概述

WR04X1000FTL是华新科(Walsin)推出的一款表面贴装厚膜固定电阻,针对小体积、宽温稳定、成本可控的电路设计需求优化,广泛适配消费电子、汽车电子等多领域量产应用。

一、产品核心身份与工艺定位

该电阻属于华新科WR04系列(对应0402封装),型号编码明确其核心特性:

  • WR04X:标识0402英制封装的厚膜电阻系列;
  • 1000:阻值编码(前三位为有效数字,第四位为倍率,即100×10⁰=100Ω);
  • FTL:后缀代表±1%精度、0402封装及标准温度系数等关键属性。

采用厚膜印刷烧结工艺制造,在氧化铝陶瓷基底上印刷电阻浆料并高温固化,兼具成本优势与基础可靠性,替代薄膜电阻满足大部分常规精密需求。

二、关键性能参数解析

1. 阻值与精度

标称阻值100Ω,精度±1%——满足大多数精密电路(如分压检测、信号匹配、限流保护)的误差要求,无需额外校准即可适配常规量产场景。

2. 功率与电压

  • 额定功率:1/16W(即62.5mW),适合小信号电路(如传感器信号调理、LED辅助限流、电源分压);
  • 额定电压:50V(直流/交流峰值),需严格控制实际工作电压不超过额定值,避免电击穿风险。

3. 温度特性

  • 温度系数(TCR):±100ppm/℃——温度每变化1℃,阻值漂移±0.01Ω(100Ω×100ppm=0.01Ω),宽温环境下性能稳定;
  • 工作温度范围:-55℃+155℃——覆盖汽车电子(-40℃+85℃)、工业控制(-20℃~+125℃)等典型宽温场景。

三、封装与物理特性

采用0402封装(英制命名,对应公制1005:1.0mm×0.5mm×0.4mm),是目前主流小型表面贴装封装之一:

  • 无引脚设计,适配自动化贴装(SMT)生产线,生产效率高;
  • 小体积优势:可显著提升PCB布局密度,适合智能手机、智能穿戴等小型化设备;
  • 封装可靠性:陶瓷基底抗机械应力,厚膜层耐磨损,适配高频振动场景。

四、适用场景与应用优势

1. 典型应用场景

  • 消费电子:智能手机电源管理模块(电池电压分压检测)、智能手表传感器信号调理、蓝牙耳机射频匹配;
  • 汽车电子:车载中控辅助电路、胎压监测(TPMS)信号滤波、车身控制器输入接口;
  • 工业控制:小型仪器仪表限流保护、PLC(可编程逻辑控制器)I/O接口、温度传感器信号调理;
  • 通信设备:WiFi模块信号衰减、射频前端匹配网络、基站小信号电路。

2. 核心应用优势

  • 成本平衡:厚膜工艺替代薄膜电阻,在满足±1%精度下降低30%以上成本;
  • 宽温适配:-55℃~+155℃工作范围,无需额外散热设计即可适配极端环境;
  • 高密度布局:0402封装使PCB每平方厘米可容纳超200颗电阻,适合小型化设备;
  • 可靠性成熟:华新科10年以上厚膜电阻量产经验,一致性良率达99.9%以上。

五、选型与使用注意事项

  1. 功率降额:实际功耗建议不超过额定功率的70%(≤43.75mW),延长使用寿命至10万小时以上;
  2. 电压限制:峰值电压不超过50V,若需更高电压需切换至高压厚膜电阻系列;
  3. 精度升级:若需±0.1%精度或±50ppm/℃温度系数,需选择华新科薄膜电阻(如WS系列);
  4. 环保合规:符合RoHS、REACH及无卤素要求,适配全球出口产品需求。

WR04X1000FTL凭借平衡的性能、成本与可靠性,成为中小功率精密电路设计的常用选型,尤其适合对体积、宽温有要求的量产应用。

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
