RTT02104JTH是RALEC旺诠推出的一款小型化贴片厚膜电阻,以0402封装为核心设计,兼顾性能稳定性与成本优势,广泛适配通用电子电路的分压、限流、滤波等基础功能需求。
该电阻属于通用型贴片厚膜电阻,聚焦小型化电路设计场景——0402封装(英制尺寸1.0mm×0.5mm)为高密度PCB布局提供支持,阻值100kΩ、精度±5%的组合覆盖大多数工业与消费电子的常规电阻应用,功率1/16W(62.5mW)匹配0402封装的功率承载能力,是中小功率电子设备的理想基础元件。
阻值固定为100kΩ,精度等级±5%——这是工业级通用电阻的典型精度,在满足电路基本功能的前提下,平衡了成本与性能:既避免了高精度电阻的溢价,又能保证信号调理、分压电路的输出稳定性(如100kΩ±5%的实际阻值范围为95kΩ~105kΩ,适配大多数模拟电路的误差容忍度)。
温度系数(TCR)为±100ppm/℃,即温度每变化1℃,阻值变化±0.01%;配合工作温度范围**-55℃~+155℃**,计算得极端温度下总阻值变化约±2.1%(温差210℃×100ppm=0.021),可稳定适配汽车电子、工业控制等对温度敏感的场景。
采用0402英制贴片封装,尺寸仅1.0mm(长)×0.5mm(宽)×0.35mm(厚),显著缩小PCB占用面积,适合智能手机、智能穿戴、小型通信模块等高密度布局的设备。
基于厚膜丝网印刷烧结工艺制造:
兼容标准SMT贴装工艺,可通过回流焊、波峰焊实现高效批量组装,无需额外手工焊接,降低生产复杂度与成本。
RTT02104JTH的参数与封装特性,使其适配以下场景:
该电阻符合电子元器件通用可靠性标准(如IEC 60115系列),具备以下可靠性特点:
综上,RTT02104JTH是一款高性价比的0402封装贴片厚膜电阻,以稳定的性能、小型化设计适配多领域电子设备的基础电阻需求,是工业与消费电子领域的通用优选元件。
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.
