0603WAF220JT5E 产品概述

本产品为 UNI-ROYAL(厚声)系列贴片厚膜电阻,封装为 0603(约 1.6 mm × 0.8 mm),阻值 22Ω,精度 ±1%,额定功率 100 mW,最大工作电压 75 V,温度系数(TCR)±100 ppm/℃,工作温度范围 -55℃ 至 +155℃。适用于空间受限的精密小功率电路场合,兼顾较高的精度与良好的温度稳定性。

一、主要参数

  • 阻值:22 Ω(标称)
  • 精度:±1%
  • 功率额定值:100 mW(室温下)
  • 最大工作电压:75 V
  • 温度系数(TCR):±100 ppm/℃(典型厚膜特性)
  • 工作温度范围:-55℃ ~ +155℃
  • 封装:0603(SMD)
  • 制程:厚膜(UNI-ROYAL 厚声)

二、产品特点

  • 小体积、轻重量:0603 封装适合高密度贴片装配与微型化设计需求。
  • 精度较高:±1% 精度满足多数模拟与数字电路中对阻值稳定性的要求。
  • 良好温漂性能:±100 ppm/℃ 的温度系数在厚膜产品中属于常见且可接受的水平,适用于一般工业与消费电子环境。
  • 容许较高工作电压:75 V 的额定工作电压超出多数同尺寸器件,有利于在较高电压节点使用时降低击穿风险。
  • 兼容无铅回流焊:厚膜金属端接,适用于常规回流焊制程(建议遵循制造商的焊接曲线)。

三、典型应用场景

  • 信号链电路中的分压、偏置与耦合网络(例如放大器、比较器前端)。
  • 阻尼/终端电阻(滤波器、传输线匹配、去耦有源元件旁的阻尼)。
  • 便携与消费类电子中小功率限流或电平设定场合。
  • 工业控制与检测电路中,对尺寸与精度有要求的电阻网络。

四、封装与焊接建议

  • 推荐 PCB 焊盘与焊膏量应与 0603 标准封装匹配,避免过量焊膏导致漂移或空洞,过少则焊接不良。
  • 回流焊工艺建议按无铅标准曲线进行,峰值温度与时间应符合 PCB 与其他元件的兼容性(通常不超过 260℃ 短时峰值)。
  • 装配与维修时避免在电阻本体上加力或挤压焊盘,以免产生机械裂纹或引起阻值漂移。
  • 储存与搬运注意防潮、防尘,长期储存应按元件供应商建议进行密封包装保管。

五、可靠性与测试

  • 常规通过温循、湿热、震动与机械冲击等可靠性测试以验证长期稳定性与焊接强度(实际测试项目与周期请参考供应商的质量文件)。
  • 对于设计关键点,建议在装配后的 PCB 上进行样机温度循环与功耗测试,验证在目标环境下的功率降额与阻值漂移情况。
  • 厚膜电阻对抗化学腐蚀能力良好,但端接金属层在恶劣环境下仍需注意镀层与保护措施。

六、选型与采购建议

  • 确认电路中的最大直流/脉冲功率与温升,必要时应对额定功率进行现场降额设计(高环境温度下功率需线性降额)。
  • 若电路对噪声、长期漂移或低温漂有更高要求,可考虑金属薄膜或合金薄膜低 TCR 产品作为替代。
  • 订购时核对完整料号、包装形式(卷带、盘装)、元件检验报告与 RoHS/无铅合规证书,确保符合生产与法规需求。

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
