RTT033162FTP是台湾旺诠(RALEC)推出的厚膜贴片电阻,采用行业标准0603封装(公制尺寸1.6mm×0.8mm),属于小体积高密度贴片元件。厚膜电阻通过丝网印刷电阻浆料于陶瓷基片、高温烧结成型,兼具成本优势与性能稳定性,是电子行业应用最广泛的电阻类型之一。旺诠作为全球知名被动元件制造商,产品在工业、汽车、消费电子等领域经市场验证,可靠性突出。
该电阻标称阻值为31.6kΩ,精度等级±1%,属于高精度厚膜电阻。不同于E24/E96系列常规阻值(如30kΩ、33kΩ),31.6kΩ为定制化阻值,可满足分压、限流、信号调理等场景对精确阻值的需求。±1%精度意味着25℃下实际阻值偏差≤±316Ω,能有效避免电路性能波动。
额定功率100mW(1/10W),指25℃环境下允许消耗的最大电功率;额定工作电压75V,需同时满足功率限制(P=V²/R,额定功率对应电压≈56.2V),75V电压上限为电路设计提供了余量,避免击穿风险。
温度系数(TCR)±100ppm/℃,表示温度每变化1℃,阻值变化±0.01%。例如:温度从25℃升至155℃(变化130℃),阻值变化≈±1.3%;降至-55℃(变化80℃),变化≈±0.8%。该系数在厚膜电阻中属常规偏优水平,宽温下阻值稳定性良好。
工作温度范围**-55℃+155℃**,覆盖工业级(-40℃+125℃)、汽车级(部分场景-40℃~+150℃)极端温度需求,可应用于高温环境(如汽车发动机舱、工业烤箱)或低温环境(北方户外设备),无需额外温度补偿。厚膜工艺陶瓷基片抗老化、机械稳定性强,长期使用阻值漂移小。
该产品凭借上述优势,成为多领域电路设计的优选被动元件。

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.
