WR08X56R0FTL是华新科(Walsin) 推出的通用型厚膜片式电阻,属于0805封装(对应公制2012尺寸)系列,专为中低功率、对精度有基础要求的电子电路设计。核心规格清晰明确:
±1%精度避免了常规±5%电阻的阻值偏差波动,例如在智能手机电池管理系统中,作为电流检测分流电阻,可准确反馈充电/放电电流,减少误判风险;在音频模块中,能稳定信号电平,提升音质一致性。
125mW额定功率对应最大允许电流约47mA(由P=I²R计算),150V工作电压支持高压小电流场景(如信号分压、高压检测)。设计时需注意:若电压接近150V,需确认电流未超功率限值,避免过载。
±100ppm/℃的温度系数表示,每变化1℃,阻值变化约0.0056Ω。在-55℃~+155℃的210℃温差内,最大阻值漂移仅1.176Ω(占比2.1%),远低于精度上限,可适配户外传感器、车间控制板等温度波动场景。
WR08X56R0FTL以精准度、宽温适应性、紧凑封装为核心,覆盖消费电子、工业控制等多领域低中功率需求。华新科成熟工艺保障可靠性,是替代常规±5%电阻的优质选择,适合对成本敏感且需基础精度的批量设计。

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.
