XL-DB2381SRBC 是成兴光(Xinglight)推出的一款红色 0.28 英寸三位 7 段数码管,采用共阳(共阳极)设计,封装为传统 DIP 形式,外形尺寸 22.5 × 10 mm。单位字符高度约 0.28 英寸(≈7.11 mm),适合在面板指示、便携设备和小型仪表等对体积和视距有中短距离要求的场合使用。
根据标称正向压降 2.0 V 与耗散功率 36 mW,可估算单段最大允许电流约为 18 mA(I = Pd / Vf ≈ 36 mW / 2 V)。推荐设计时采用限流电阻或恒流驱动,连续工作电流建议控制在其最大值之下(常见设计 5–15 mA 区间),以延长寿命并降低发热。多位复用显示时,应考虑占空比和刷新率:建议复用频率不低于 100 Hz 以避免可见闪烁,同时根据占空比调整驱动电流以保持亮度一致。
本件为 DIP 插脚封装,整体尺寸 22.5 × 10 mm,便于插装或波峰/手工焊接到 PCB。0.28 英寸字符适用于面板和仪表的近距离读数。安装时注意焊接温度与焊接时间,避免因过热造成内部发光二极管性能退化。
适用于便携仪表、消费电子面板、计数器、小型电源指示、工业控制面板及教育电子等领域,尤其适合对红色指示灯及三位数字显示有体积紧凑需求的场合。
订购型号:XL-DB2381SRBC,品牌成兴光(Xinglight)。采购时请确认封装(DIP)、位数(3 位)、极性(共阳)与颜色(红色)等关键参数。如需样品测试或批量采购,可联系供应商索取规格书(Datasheet)以获取完整引脚图、电性曲线与典型应用电路。

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.
