WR06X5603FTL是华新科(Walsin) 推出的WR系列厚膜贴片电阻,采用0603(英制)/1608(公制) 小型化贴片封装,是一款针对精准阻值、宽温环境设计的通用型被动元件。型号中“WR”代表华新科厚膜电阻系列,“06X”对应0603封装规格,“5603”为阻值代码(560×10³Ω=560kΩ),“FTL”明确了精度(±1%)、温度系数(±100ppm/℃)等核心参数,定位覆盖工业、消费电子等多领域的常规精准应用场景。
该电阻标称阻值为560kΩ,精度等级为**±1%**,属于工业及消费电子领域常用的“高精度”等级(区别于±5%、±10%的普通等级)。1%精度可满足信号调理、分压电路、滤波网络等对阻值一致性要求较高的场景,无需额外筛选即可实现批量应用的性能稳定。
额定功率为100mW(0.1W),最大工作电压为75V。两者匹配性良好:根据欧姆定律,最大工作电流约为134μA(I=V/R=75V/560kΩ),此时功率消耗为P=I²R≈100mW,刚好达到额定功率上限,可避免因过功率导致的性能衰减或失效。
温度系数为**±100ppm/℃**,表示阻值随温度变化的速率:每升高或降低1℃,阻值变化为标称值的万分之一百(即0.01%)。例如,当环境温度从25℃(常温)变化至125℃(变化100℃)时,阻值变化约1%,与精度等级(±1%)一致,可保证宽温环境下的阻值稳定性。
工作温区覆盖**-55℃+155℃**,超出常规工业级(-40℃+125℃)的温度上限,可适应极端环境(如高温车间、户外低温场景),无需额外搭配温度补偿电路,降低系统设计复杂度。
采用0603贴片封装(公制尺寸约1.6mm×0.8mm×0.45mm,具体以厂商 datasheet 为准),具备以下特点:
结合参数特性,WR06X5603FTL可广泛应用于:
该产品凭借精准稳定的电性能、宽温适应性及小型化封装,成为多领域电子设备的可靠电阻选择。

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.
