华新科(Walsin)WR04X1004FTL是一款专为高密度电路设计的小封装厚膜电阻,凭借稳定的性能、宽温适应性及高性价比,广泛应用于消费电子、工业控制、汽车电子等领域。以下从核心参数、工艺特性、应用场景等维度展开详细介绍。
阻值1MΩ±1%,通过激光微调工艺实现高精度控制,偏差范围满足多数通用电路的信号调理、分压、偏置需求。厚膜电阻的阻值稳定性优于碳膜电阻,长期工作后阻值漂移较小。
额定功率1/16W(62.5mW),适配0402小封装的散热能力。实际应用中需注意温度降额:125℃以上时功率线性降低(如155℃时仅用额定功率的50%),避免过热失效。
最大工作电压50V是耐压上限,需同时满足“电压≤50V”与“功率≤实际可用功率”(如1MΩ在50V下功率仅2.5mW,电压约束更严格)。
±100ppm/℃即每℃阻值变±0.01%,-55℃至155℃总变化约±2.1%,可满足汽车/工业场景的温度稳定性要求。
0402封装(1005公制)尺寸极小,适合手机、智能穿戴等便携设备的高密度PCB布局,有效节省空间。
-55℃~+155℃覆盖工业、汽车级场景,无需额外散热。
操作时佩戴防静电手环,使用防静电工作台,避免精度下降。
华新科WR04X1004FTL厚膜电阻凭借小封装、宽温、高精度、高可靠性,成为中高端电子设备高密度电路的优选元件,平衡性能与成本,适配多领域差异化需求。

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.
