RTT0560R4FTP是RALEC(旺诠)品牌推出的一款0805封装厚膜贴片电阻,专为低功耗、高精度电子电路设计,兼顾性能稳定性与批量生产适配性,可满足工业控制、汽车电子、消费电子等多领域的应用需求。
该电阻属于厚膜贴片电阻范畴,型号编码清晰对应核心特征:“RTT05”关联0805封装(旺诠品牌编码逻辑),“60R4”代表标称阻值60.4Ω,“FTP”为厚膜工艺专属标识。作为旺诠旗下的标准化贴片电阻,其定位是小功率高精度通用型器件——既适配自动化SMT生产线的高效组装,又能在宽温环境下保持稳定性能,适合对成本、体积、精度有综合要求的场景。
标称阻值为60.4Ω,精度等级±1%,属于工业级常用高精度规格。相比±5%的普通电阻,能有效降低电路信号失真、功率损耗偏差,适用于传感器信号调理、滤波网络等对阻值准确性要求较高的模块,避免因阻值偏差导致的系统性能波动。
额定功率125mW,满足低功耗电路(如便携式设备、小型电源)的功率需求;额定工作电压150V,需注意实际工作电压不得超过该值(否则可能导致电阻过热、击穿),适配低压至中压(≤150V)的电子系统,覆盖多数消费电子与工业辅助电路的电压范围。
温度系数(TCR)为±100ppm/℃,意味着温度每变化1℃,阻值变化幅度≤±0.01%;结合工作温度范围-55℃~+155℃,计算得全温区阻值最大偏差为±2.1%(100ppm×210℃),稳定性优于多数普通厚膜电阻,可适应汽车发动机舱(高温)、户外工业设备(低温)等极端温度场景。
封装尺寸为2.0mm×1.2mm(国际0805标准),体积小巧,可显著降低电路板面积占用,适配便携式设备、小型化电子模块的高密度布局;贴片式结构完全兼容SMT自动化生产,能提升组装效率与一致性,降低人工成本,适合大规模量产需求。
采用厚膜印刷工艺制造,相比薄膜电阻成本更低、抗过载能力更强;相比线绕电阻体积缩小数倍,且无电感效应(适合高频电路),综合性能平衡了成本与性能需求,避免了线绕电阻的高频损耗问题,适配通信、射频等场景。
RALEC(旺诠)作为全球知名电阻制造商,在厚膜电阻领域拥有成熟的研发与生产体系:
用于传感器信号调理电路(如温度、压力传感器的分压、限流),±1%精度保证信号采集准确性;宽温范围适配车间不同温度环境(如冬季低温、夏季高温),避免因温度变化导致的信号偏差。
适配汽车仪表盘、车载通信模块的辅助电路,155℃高温耐受能力可应对发动机舱附近的高温环境,0805小体积适配汽车电子的小型化趋势,同时满足车载系统的可靠性要求。
用于手机、平板的电源滤波、信号匹配电路,125mW功率满足低功耗需求,0805封装适配设备的高密度布局,提升产品便携性。
用于基站、路由器的滤波、阻抗匹配电路,无电感效应(厚膜工艺)适配高频信号传输,稳定的阻值偏差保证信号质量,降低信号反射与损耗。
总结:RTT0560R4FTP厚膜贴片电阻凭借高精度、宽温适应、小体积与成本优势,成为多领域电子电路的可靠选择,可满足不同场景下的性能与量产需求,是工业、汽车、消费电子等领域的实用型电阻器件。
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.
