1206W4J0331T5E 产品概述

一、产品简介

1206W4J0331T5E 是 UNI-ROYAL(厚声)系列的贴片厚膜电阻,封装为 1206(约 3.2 × 1.6 mm),阻值 330Ω,精度 ±5%,额定功率 0.25W,额定工作电压 200V。工作温度范围为 -55℃ 至 +155℃,温度系数(TCR)为 ±100 ppm/℃。该型号面向通用电子装配场景,兼顾成本与可靠性,适合大批量表面贴装生产。

二、主要性能参数

  • 阻值:330Ω ±5%
  • 封装:1206(3216公制)
  • 功率额定:250 mW(在规定环境与散热条件下)
  • 最大工作电压:200 V
  • 温度系数:±100 ppm/℃(典型,见具体出厂报告)
  • 工作温度:-55℃ ~ +155℃
  • 工艺类型:厚膜电阻

三、结构与工艺特性

采用厚膜电阻工艺,阻性薄膜印刷在陶瓷基体上,经高温烧结而成。该结构在成本与批量一致性上具有优势,端接具有良好的焊接性以适配回流焊工艺。由于为厚膜元件,其在热噪声、频率响应及高频寄生方面与薄膜电阻存在差异,适合一般直流与低频交流应用。

四、典型应用场景

  • 消费类电子:电源分压、限流、偏置与信号阻抗匹配
  • 工业控制:控制板上通用限流与拉/下拉电阻
  • 照明驱动:LED 限流(需注意功率与环境温度)
  • 通信设备与家电:阻值稳定要求不高的通用场合

五、选型与使用建议

  1. 功率与热管理:在封装内功率以环境温度与散热条件决定,建议按厂商热功率降额曲线设计,避免长时间在额定功率上工作。
  2. 电压限制:单元最大工作电压 200V,设计时应考虑最大过电压与浪涌。
  3. 温度与漂移:TCR ±100 ppm/℃,若需高稳定性或低温漂,应选择更低TCR或更高精度的器件。
  4. 焊接与装配:兼容标准回流焊工艺;为保证可靠性,建议遵守厂商推荐的焊接温度曲线与清洗流程。
  5. 测试与验收:大批量使用时建议抽检阻值与焊接可靠性,并进行温升与寿命验证。

六、包装与可靠性

常见为卷带(Tape & Reel)包装,便于贴片机取放。厚膜工艺在耐湿、耐振方面具有良好表现,具体可靠性指标(如寿命、耐潮湿试验、焊接热冲击等)请参考厂商完整数据手册或出具的可靠性报告。

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
