RM02FTN5600是大毅科技推出的一款0201封装高精度片式固定电阻,专为小型化、低功耗电子设备的精准电路设计打造,核心参数覆盖阻值、精度、功率等关键指标,适配多类消费电子与工业小型模块场景。
该电阻属于大毅科技常规片式电阻系列,聚焦高密度PCB布局与低功耗精准信号处理需求,主要面向可穿戴设备、IoT终端、小型消费电子及工业传感器接口等场景,解决传统大封装电阻无法满足的小型化设计痛点,平衡了尺寸、精度与可靠性的需求。
阻值为560Ω±1%,精度达到±1%(实际阻值区间为554.4Ω~565.6Ω),可稳定支撑信号调理电路中的分压、限流、滤波等功能,避免因阻值偏差导致的信号失真或功率损耗异常,适配对精度要求较高的传感器接口、音频电路等场景。
额定功率为50mW(1/20W),与0201小封装特性精准匹配,适合电池供电的低功耗设备(如智能手环单次充电续航7-14天的电路设计),可有效降低整机功耗,延长电池使用寿命,同时避免因功率过载导致的电阻失效。
温度系数为**±200ppm/℃**,表示温度每变化1℃,阻值变化量为560Ω×200×10⁻⁶=0.112mΩ。若设备工作环境温度在-40℃~85℃区间(温差125℃),阻值最大变化仅约14mΩ,满足常规室内外环境下的稳定工作需求,无需额外温度补偿电路。
额定电压为25V,即电阻两端允许施加的最大直流/交流电压有效值为25V,可避免过压导致的绝缘击穿或阻值漂移,适配多数低电压电子电路(如3.7V锂电池供电、5V USB供电等场景),提升电路安全性。
采用0201封装(英制尺寸:0.02英寸×0.01英寸,公制尺寸:0.6mm×0.3mm),厚度约0.23mm,相比0402封装体积缩小约70%,可大幅提升PCB单位面积的元件密度,适合智能手机、智能手表等追求轻薄化设计的产品,有效降低整机体积与重量。
大毅科技作为专业电子元器件厂商,RM02FTN5600经过多项行业标准可靠性测试验证:
RM02FTN5600凭借小封装、高精度、低功耗的特性,成为小型化电子设备精准电路设计的可靠选择,适配多类市场需求,是消费电子与工业小型化领域的常用电阻方案。
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.
