RK73B1JTTD220J 是由 KOA Speer Electronics, Inc. 制造的汽车级电阻器,属于 RK73B 系列。这个产品结合了高性能、可靠性和适应各种环境条件的能力,特别适用于汽车电子和其他要求严格的应用场景。
RK73B1JTTD220J 的电阻值为 22 Ohms,具有 ±5% 的容差。这意味着实际电阻值可能在 20.9 Ohms 到 23.1 Ohms 之间,确保了在各种应用中的一致性和可靠性。
该电阻器具有 0.125W(1/8W)的功率等级,适用于中低功率的电子设备。其小型化的 0603 封装(1608 公制)使其非常适合于紧凑的 PCB 设计,节省空间同时保持高性能。
RK73B1JTTD220J 的工作温度范围从 -55°C 到 155°C,这使得它能够在极端环境下保持稳定运行。这种广泛的温度适应性使其成为汽车电子、工业控制和其他严苛环境中的理想选择。
该电阻器的温度系数为 ±200ppm/°C,这表明其电阻值随着温度变化而变化的程度相对较小。这种稳定性对于需要精确控制电阻值的应用尤其重要。
RK73B1JTTD220J 符合 AEC-Q200 标准,这是汽车电子行业对电子组件的一项严格认证。这种认证保证了该电阻器在汽车应用中能够承受各种环境条件和使用寿命要求。
该产品具有防潮特性,能够抵御湿气和腐蚀,进一步提高了其在恶劣环境中的可靠性和寿命。
RK73B1JTTD220J 广泛应用于以下领域:
RK73B1JTTD220J 是一款高性能、可靠性的汽车级电阻器,通过其精确的电阻值、广泛的工作温度范围、低温漂移和防潮特性,成为各种严苛环境下的理想选择。其小型化设计和符合 AEC-Q200 标准的认证,使其在汽车电子、工业控制以及其他要求严格的应用中得到了广泛应用。

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.
