MR04X1000FTL 厚膜片式电阻器产品概述

一、产品定位与核心属性

MR04X1000FTL是华新科(Walsin)推出的通用型表面贴装厚膜电阻,聚焦小体积、高精度、低功耗场景的电路设计需求。该电阻采用0402封装,以100Ω为标准阻值,搭配±1%精度、100mW额定功率,兼顾性能稳定性与成本经济性,是消费电子、工业控制等领域的常用基础元器件。

二、关键性能参数深度解析

1. 阻值与精度

标称阻值100Ω,精度±1%,可满足大多数信号调理、分压、限流电路对阻值偏差的要求——例如传感器信号放大电路中,避免因阻值偏差导致放大倍数波动(偏差≤1%可保证信号传输一致性)。

2. 功率与电压

  • 额定功率100mW(即1/10W),适配低功耗电路设计(如便携式设备、传感器前端);
  • 最大工作电压50V,高于同功率级多数竞品,可有效降低过压击穿风险(如部分低压电源滤波场景无需额外防护)。

3. 温度特性

温度系数±100ppm/℃,意味着温度每变化1℃,阻值变化±0.01Ω。在-55℃至+155℃的宽温范围内,最大阻值变化约±2.1Ω,满足宽温环境下的阻值稳定性需求(如户外设备、工业现场的极端温度场景)。

三、封装与物理特性

采用0402封装(英制0.04″×0.02″,公制1005,实际尺寸约1.0mm×0.5mm×0.3mm),具备以下优势:

  • 表面贴装工艺完全适配自动化SMT生产线,生产效率高;
  • 无引脚设计减少寄生电感、电容,适合高密度PCB布局(如智能手机、可穿戴设备的小型化设计);
  • 厚膜工艺相比薄膜电阻成本更低,同时具备较好的抗硫化性能,可避免部分潮湿/含硫环境下的失效风险。

四、典型应用场景

  1. 便携式电子设备:智能手机、智能手表、无线耳机等产品的电源滤波、信号分压、射频匹配网络(0402封装匹配小体积需求);
  2. 传感器信号调理:温度传感器、压力传感器的前端放大偏置电阻、限流电阻(100mW低功耗适配传感器特性);
  3. 工业控制辅助电路:PLC、变频器的信号隔离、辅助电源限流(-55℃~+155℃宽温覆盖工业级环境);
  4. 消费类电子模块:蓝牙模块、WiFi模块的信号衰减、阻抗匹配(±1%精度满足射频电路基本要求)。

五、可靠性与环境适应性

  1. 宽温工作能力:-55℃至+155℃的工作温度范围,符合工业级设备的环境要求,可应对户外、高温车间等极端场景;
  2. 环保合规:符合RoHS标准,无铅设计满足欧盟环保法规,可用于绿色电子产品设计;
  3. 可靠性测试:产品经过高温存储(155℃/1000h)、温度循环(-55℃~+155℃/1000次)、湿度测试(85℃/85%RH/1000h)等严格测试,确保批次一致性与长期稳定性。

六、品牌与品质保障

华新科作为全球知名被动元器件制造商,拥有超过30年的生产经验,产品通过ISO9001质量管理体系、ISO/TS16949汽车行业认证。MR04X系列电阻广泛应用于华为、小米、苹果等知名厂商的供应链中,批次一致性好,可有效降低电子厂商的供应链风险。

该产品以平衡的性能、可靠的品质,成为小体积低功耗电路设计的优选基础元器件。

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
