DEA162450BT-1298A1 是 TDK 面向 2.4 GHz 无线通信频段设计的小型表面贴装带通滤波器,覆盖绝对带宽 2.4 GHz 至 2.5 GHz(中心频率 2.45 GHz)。器件为 50 Ω 体系匹配,典型插入损耗 0.91 dB,隔离或带外衰减可达 26.7 dB。器件封装为 SMD-3P(1.6 × 0.7 mm),工作温度范围 -40 ℃ 至 +85 ℃,适用于空间受限且需高性能射频前端滤波的方案。
DEA162450BT-1298A1 为 SMD 封装,适合自动化贴装与无铅回流焊接。器件设计考虑了热循环与机械振动的可靠性,工作温度覆盖工业级范围,适合长期稳定运行的无线产品。建议在高湿或腐蚀性环境中采取防护封装或涂覆措施以延长寿命。
在样机阶段建议做回波损耗(S11)、插入损耗(S21)与群时延测试,验证滤波器在实际 PCB 布局、邻近元件与天线接入条件下的表现。如需更高带外抑制或更低插损,可与射频工程师或 TDK 支持团队讨论定制或替代型号。

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.
