WR08X750JTL片式厚膜电阻产品概述

一、产品基本定位与型号解析

WR08X750JTL是华新科(Walsin)推出的通用型片式厚膜电阻,型号字符对应清晰:

  • WR:厚膜电阻系列标识;
  • 08:封装尺寸代码(英制0805,对应公制2.0mm×1.25mm);
  • X:工艺优化标识;
  • 750:阻值编码(前两位“75”为有效数字,第三位“0”为倍率10⁰,即75Ω);
  • J:精度代码(±5%工业级精度);
  • TL:封装与包装规格标识。

该产品主打高性价比+稳定可靠性,适配多数常规电子电路的电阻需求,无需额外精密参数设计。

二、核心参数详细说明

作为0805封装的小功率厚膜电阻,参数针对通用场景优化,关键指标及实际意义如下:

  1. 阻值与精度:标称75Ω,精度±5%(J档),满足非精密测量、信号调理等场景的误差要求(如LED驱动、I/O限流无需更高精度);
  2. 功率等级:额定功率125mW(等效1/8W),匹配0805封装的功率承载能力;实际应用需降额20%以上(建议功率≤100mW),避免长期过载;
  3. 工作电压:最大150V(直流/交流有效值),需注意“电压×电流≤额定功率”(150V×0.83mA≈125mW),过压可能导致击穿;
  4. 温度特性:温度系数±100ppm/℃,即温度每变1℃,阻值变化百万分之一百;全温区(-55℃+155℃)内阻值最大变化约2.1%,叠加精度后总波动可控(75Ω×(1±7.1%)≈69.680.3Ω);
  5. 工作温度范围:-55℃~+155℃,覆盖工业级环境(如低温存储、设备内部散热),无需额外散热设计。

三、封装与工艺优势

  1. 0805封装特点:尺寸2.0mm×1.25mm×0.5mm(典型),适配SMT表面贴装工艺,适合高密度PCB布局(如手机主板、小型模块),降低电路体积;
  2. 厚膜工艺优势:采用厚膜印刷技术制备电阻层,相比薄膜电阻成本低30%以上,且抗浪涌能力更强(可承受短时间过流冲击);华新科工艺优化后,电阻层均匀性好,批次一致性偏差≤1%,减少批量应用筛选成本。

四、典型应用场景

因参数均衡、成本可控,广泛应用于以下领域:

  1. 消费电子:手机/平板的电源滤波(分压/限流)、LED指示灯驱动、MCU I/O端口限流;
  2. 工业控制:小型传感器接口(温度/压力信号调理)、低功耗PLC辅助电路、小型继电器驱动限流;
  3. 通信设备:路由器/交换机电源模块辅助电阻、信号传输匹配电阻(低功率场景);
  4. 汽车电子(非车规):车载充电器辅助电阻、车内LED氛围灯驱动(需确认实际工作温度≤155℃)。

五、品牌与可靠性保障

华新科(Walsin)是全球TOP5被动元件厂商,WR08X750JTL系列满足:

  1. 环保认证:通过RoHS 2.0、REACH,无铅无卤,适配绿色电子产品;
  2. 可靠性测试:经高温老化(155℃×1000h)、温度循环(-55~+155℃×1000次)、湿度测试(85℃/85%RH×1000h),符合IEC 61000、JIS C 5201标准;
  3. 批量一致性:自动化生产+在线检测,批次间参数偏差≤0.5%,适合大规模量产。

该产品以“通用场景覆盖+成本优势”为核心,是电子设计中替代进口同类产品的高性价比选择。

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
