KTR18EZPJ104是ROHM(罗姆)推出的1206封装厚膜贴片电阻,针对中低精度、中等功率需求的电子电路设计,兼顾成本控制与可靠性,广泛适配消费电子、工业控制等多领域。该型号以100kΩ为标准阻值,±5%精度覆盖多数常规电路的偏差要求,250mW额定功率满足低功耗至中等负载的稳定工作需求,是电子设计中常规电阻的高性价比优选。
标准阻值为100kΩ(代码标识“104”,即10×10⁴Ω),±5%精度是厚膜电阻的主流规格——无需额外高精度校准即可满足分压、限流、偏置电路等场景的匹配需求,避免因精度冗余导致的成本浪费。批量生产时,罗姆通过严格工艺管控确保阻值一致性(偏差波动≤±0.1%),降低电路设计中的匹配难度。
采用1206英制封装(公制3216,3.2mm×1.6mm),体积紧凑,适配主流SMT生产线,支持高速贴装(每小时可达数万片),降低生产环节的人工与时间成本;同时兼容无铅焊接工艺(RoHS compliant),符合全球环保要求。
罗姆采用厚膜印刷+高温烧结工艺:
罗姆对该型号进行高温老化(155℃×1000小时)、湿度循环(85℃/85%RH×500小时) 测试,阻值漂移≤±0.5%,可满足5年以上的稳定工作需求,适合工业设备、汽车电子等对寿命要求高的场景。
KTR18EZPJ104以平衡的成本、稳定的性能与宽适配性,成为电子设计中常规电阻的核心选型之一,尤其适合对精度、功率要求适中,且需宽温可靠性的场景。

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.
