SC0402J0000I2ANRH是信维通信(Sunway)推出的一款0402封装0Ω厚膜贴片电阻,主打小体积、高可靠性,适用于多种电子设备的电路短接、电流检测及调试预留等场景,是无源元件中替代导线的实用选择。
该电阻采用厚膜工艺制造,核心功能为电路低阻连接/短接,替代传统导线或跳线,同时具备一定功率承载能力与温度稳定性。其0402封装(英制尺寸,对应公制1005:长1.0mm×宽0.5mm)适配高密度PCB布线,尤其适合消费电子、工业控制等对体积敏感的领域。
标称阻值为0Ω(实际存在毫欧级微小阻值,因工艺限制),精度为**±5%**——实际阻值与标称值偏差不超过5%,满足常规短接、低阻检测的精度需求。
额定功率为62.5mW,指工作温度范围内可长期稳定承载的最大功率耗散。若实际功率超限,可能导致电阻升温、阻值漂移甚至熔断。
温度系数为**±300ppm/℃**,表示每变化1℃,阻值相对变化0.03%(300ppm=0.03%),确保宽温下的阻值稳定性,适合高低温交替环境。
支持**-55℃+155℃**宽温工作,覆盖工业级(-40℃+85℃)及部分高温场景,可满足户外设备、车载辅助系统等需求。
采用陶瓷基底+丝网印刷电阻层工艺,相比薄膜电阻成本更低,相比绕线电阻体积更小,抗机械应力、抗潮湿性能优异。
该电阻的0Ω特性与小体积使其在多场景发挥作用:
信维通信对该产品进行多项可靠性测试:
SC0402J0000I2ANRH广泛适用于:
总结:该产品以小体积、宽温特性、稳定厚膜工艺为核心优势,是电子设计中替代导线、实现灵活短接的实用选择,适合对成本与可靠性均有要求的批量应用场景。

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.
