ARG03BTC5601为Viking(光颉)品牌推出的高精度薄膜贴片电阻,核心参数明确且适配精密电路需求:
0603小型化封装
体积紧凑,适合高密度表面贴装(SMT),可有效节省电路板空间,满足智能手机、可穿戴设备等小型化产品的布局需求;焊接兼容性强,适配回流焊、波峰焊等常规工艺。
薄膜电阻工艺优势
采用真空溅射镍铬薄膜技术,相比厚膜电阻(丝网印刷):
高精度低漂移
±0.1%的阻值精度结合±25ppm/℃的温度系数,确保在宽温度范围内阻值稳定(如100℃温差下,阻值漂移仅≤1.4Ω),可满足精密测量、校准电路的严格要求。
宽温环境适应性
-55℃至+155℃的工作温度范围,适配户外设备、工业控制模块等极端温度场景(如冬季低温、夏季高温车间)。
高可靠性与稳定性
在额定参数内工作时,阻值长期变化率低(典型值≤0.05%/1000小时老化);抗机械振动(符合MIL-STD-202标准)、湿度(封装密封性能好)能力强,适合恶劣环境应用。
高频特性优异
薄膜工艺的低寄生参数,使其在射频电路(如WiFi、蓝牙模块)、高速信号处理电路中表现出色,可有效减少信号损耗和失真。
精密测量仪器
示波器、数字万用表、频谱分析仪的校准电阻、信号衰减网络,依赖其高精度低漂移特性保证测量准确性。
医疗电子设备
血糖仪、心电监护仪、输液泵的信号调理电路,需稳定可靠的电阻元件保证医疗数据的精确性。
工业控制模块
PLC(可编程逻辑控制器)、传感器接口电路、电机驱动模块,宽温范围适配工业现场的极端温度。
消费电子小型化产品
智能手机的电源管理单元(PMU)、音频解码电路,0603封装满足高密度贴装需求。
射频与通信设备
WiFi6模块、蓝牙5.0模块的阻抗匹配电阻、滤波电路,发挥其高频特性优势。
功率降额
环境温度超过25℃时,需按光颉提供的降额曲线降低功率(如125℃时功率降额至50%),避免过热损坏。
电压限制
实际工作电压不得超过75V,若需更高电压应用,需选择同阻值更高功率的型号(如0805封装的1/8W电阻)。
焊接规范
采用回流焊工艺时,峰值温度需控制在245℃±5℃,焊接时间≤10秒,避免高温损坏薄膜层。
ARG03BTC5601凭借高精度、宽温稳定、小体积等特性,成为精密电子领域的常用元件,可有效提升电路性能与可靠性。
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.
