WR08X56R0FTL 厚膜片式电阻产品概述

一、产品基本定位与核心规格

WR08X56R0FTL是华新科(Walsin) 推出的通用型厚膜片式电阻,属于0805封装(对应公制2012尺寸)系列,专为中低功率、对精度有基础要求的电子电路设计。核心规格清晰明确:

  • 阻值:56Ω(欧姆)
  • 精度:±1%(优于常规±5%精度,满足多数通用电路一致性需求)
  • 额定功率:125mW(低至中等功率场景适配)
  • 工作电压:150V(最大连续工作电压,需结合功率确认电流限值)
  • 温度系数:±100ppm/℃(宽温下阻值漂移小)
  • 工作温度:-55℃~+155℃(工业级宽温,适应极端环境)

二、关键性能参数的实际价值

(1)阻值精度:适配精准度需求

±1%精度避免了常规±5%电阻的阻值偏差波动,例如在智能手机电池管理系统中,作为电流检测分流电阻,可准确反馈充电/放电电流,减少误判风险;在音频模块中,能稳定信号电平,提升音质一致性。

(2)功率与电压:覆盖主流场景

125mW额定功率对应最大允许电流约47mA(由P=I²R计算),150V工作电压支持高压小电流场景(如信号分压、高压检测)。设计时需注意:若电压接近150V,需确认电流未超功率限值,避免过载。

(3)温度特性:宽温下的稳定性

±100ppm/℃的温度系数表示,每变化1℃,阻值变化约0.0056Ω。在-55℃~+155℃的210℃温差内,最大阻值漂移仅1.176Ω(占比2.1%),远低于精度上限,可适配户外传感器、车间控制板等温度波动场景。

三、产品优势与典型应用

(1)核心优势

  • 工艺可靠:华新科厚膜工艺(丝网印刷+烧结)耐老化、抗冲击,长期使用性能稳定;
  • 封装紧凑:0805尺寸(2.0mm×1.2mm)节省PCB空间,适配小型化设备;
  • 贴装兼容:SMD封装支持自动化贴装,适合批量生产;
  • 宽温适配:工业级温度范围无需额外降额,降低设计复杂度。

(2)典型应用

  • 消费电子:手机/平板的电源管理(电流检测、电压分压)、音频电路(信号调理)、LED背光驱动(限流);
  • 工业控制:小型PLC的I/O接口板(信号限流、电平转换)、传感器信号调理(如温度传感器分压);
  • 汽车电子:辅助系统(倒车雷达信号处理、氛围灯驱动)的低功率电路(宽温特性适配车载环境);
  • 通信设备:小型基站、路由器的射频辅助电路(滤波器匹配、信号衰减)。

四、选型与使用注意事项

(1)选型要点

  • 封装匹配:需确认PCB焊盘为0805尺寸,避免不兼容;
  • 功率余量:实际功率建议不超额定值的80%(≤100mW),延长寿命;
  • 精度匹配:若需更高精度(如±0.1%)选其他系列,低成本需求可选±5%电阻。

(2)使用注意

  • 焊接工艺:回流焊峰值温度≤260℃(持续≤10秒),手工焊≤350℃(≤3秒),避免高温损坏;
  • 存储环境:建议25℃±5℃、湿度40%~60%,受潮后需烘干(105℃/4小时);
  • 应力防护:避免机械冲击、振动过大,防止封装开裂或阻值变化。

五、总结

WR08X56R0FTL以精准度、宽温适应性、紧凑封装为核心,覆盖消费电子、工业控制等多领域低中功率需求。华新科成熟工艺保障可靠性,是替代常规±5%电阻的优质选择,适合对成本敏感且需基础精度的批量设计。

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
