SC0805J2001F4ANRH是信维通信(Sunway)推出的一款通用型0805封装厚膜贴片电阻,专为电子电路中的基础阻抗应用设计,兼具稳定性能、宽环境适应性与高性价比,广泛适用于消费电子、工业控制等多个领域。
该电阻采用厚膜工艺制造,以陶瓷基底为载体,通过印刷厚膜电阻浆料、高温烧结成型,既保证了可靠性,又控制了成本;封装规格为0805(公制尺寸2.0mm×1.25mm),符合贴片元件标准化尺寸,适配多数PCB设计;品牌为信维通信(Sunway),作为国内知名电子元器件供应商,产品质量符合IEC、GB等行业标准要求。
标称阻值为2kΩ(对应代码“2001”),精度等级为**±5%**,满足一般电路对阻值偏差的需求(如电源分压、信号限流等场景无需高精度时,可有效控制成本)。
温度系数为**±100ppm/℃**,表示温度每变化1℃,阻值变化±100×10⁻⁶×标称阻值(如2kΩ电阻在100℃温差下,阻值变化±20Ω),适用于温度变化幅度不大的常规场景。
工作温度范围覆盖**-55℃~+155℃**,可满足工业级高温场景(如工业烤箱、高温传感器电路)及低温环境(如北方户外设备)的需求;厚膜工艺赋予其较好的抗机械应力能力,焊接后不易因热胀冷缩开裂,长期使用阻值漂移率低,可靠性符合通信设备、工业控制等领域的应用要求。
该电阻因性价比突出、性能稳定,广泛应用于以下场景:
SC0805J2001F4ANRH作为信维通信的通用型0805厚膜电阻,平衡了性能与成本,适用于多数中低端电子电路的基础阻抗需求,是电子设计中常用的标准元件之一。其宽温度范围、稳定的电性能及可靠的工艺,可满足消费电子、工业控制等领域的多样化应用场景。

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.
