华新科(Walsin)WR04X2000FTL是一款专为高密度电路设计的小功率通用厚膜电阻,凭借稳定的电气性能、宽温适应性与0402封装的小型化优势,广泛应用于消费电子、工业控制等领域。以下从核心维度展开详细概述。
该电阻属于华新科常规厚膜电阻系列,核心定位为成本与性能平衡的通用型元件。华新科作为全球被动元件头部厂商,拥有数十年生产经验,其厚膜电阻采用成熟的丝网印刷烧结工艺,品质符合国际电工委员会(IEC)及行业标准,在消费电子、工业控制供应链中具备较高市场认可度。
0402封装体积仅为0402(2.0mm×1.0mm)封装的1/4,可显著节省PCB空间,尤其适合智能手机、智能穿戴等便携设备的高密度电路设计。
厚膜工艺带来的阻值稳定性优于碳膜电阻,长期工作下阻值漂移小;±1%精度与±100ppm/℃TCR的组合,可满足信号调理、电源偏置等对阻值稳定性要求较高的场景。
-55~155℃的工作温度范围,可覆盖工业控制、车载辅助电路(如仪表盘背光、传感器接口)等场景,无需额外降额设计即可稳定工作。
产品符合RoHS 2.0、REACH等环保标准,无铅无卤;同时具备抗振动(符合IEC 60068-2-6)、抗冲击(符合IEC 60068-2-27)性能,适合 harsh 环境应用。
为确保产品可靠性与寿命,使用时需注意以下几点:
综上,华新科WR04X2000FTL是一款性价比突出的小功率厚膜电阻,具备小型化、宽温稳定等特点,可满足大多数通用电路的设计需求,是消费电子、工业控制等领域的优选元件之一。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
