WR06X753JTL是华新科(Walsin)推出的一款小型化表面贴装厚膜固定电阻,针对电子设备小型化、集成化需求设计,具备稳定的电气性能与广泛的环境适应性,适用于多类消费电子、工业控制及通信场景。
该产品属于厚膜片式固定电阻范畴,采用表面贴装封装,无极性设计便于自动化贴装;品牌为华新科(Walsin),型号WR06X753JTL,是市场上应用较广泛的通用型被动元件之一,符合国际电子元件标准规范。
阻值标称75kΩ(对应3位编码“753”,即75×10³Ω),精度等级为±5%(对应E24系列精度标识“J”),可满足一般非精密电路的阻值匹配需求,无需额外高精度校准。
额定功率100mW(即1/10W),额定工作电压75V;通过功率-电压验证:( P=V^2/R = 75^2/75000 = 56.25mW ),远低于额定功率,确保长期工作安全可靠,无过热风险。
温度系数为±100ppm/℃,即温度每变化1℃,阻值变化±7.5Ω(( 75000Ω×100×10^{-6}/℃ )),该参数可保证产品在温度波动场景下的阻值稳定性,适合温度变化范围适中的应用环境。
采用0603封装(英制0.06×0.03英寸,公制1.6mm×0.8mm),是小型化电子设备常用的封装规格;封装基片为陶瓷材料,具备良好的热传导性与机械强度,可承受贴装过程中的焊接应力;表面电极采用可焊性优良的合金材料,适配回流焊、波峰焊等自动化生产工艺,贴装效率高。
因体积小、性能稳定,WR06X753JTL适用于以下场景:
华新科作为全球知名被动元件厂商,WR06X753JTL通过以下品质认证:
该产品凭借小型化、稳定可靠的特性,成为电子设备设计中通用电阻的优选方案之一,可有效降低电路板空间占用,提升集成度。
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.
