XL-DB3461SRBC 产品概述
一、产品简介
XL-DB3461SRBC（品牌：Xinglight/成兴光）是一款0.36英寸红色7段LED数码管，4位显示、共阳极封装，典型尺寸封装为DIP 30×14mm。适用于小型面板、便携仪表及简单数字显示需求，外观紧凑、易于穿孔安装与批量生产。
二、主要参数
- 显示位数：4位（7段 + 小数点）
- 字符尺寸：0.36英寸
- 发光颜色：红色
- LED极性：共阳（共阳极）
- 发光强度：20 mcd（典型）
- 正向压降：2.0 V（典型）
- 最大耗散功率 Pd：36 mW（单段）
- 工作温度范围：-30 °C ～ +70 °C
- 封装形式：DIP，封装尺寸约 30×14 mm
三、电气特性与驱动建议
根据给定参数，可计算单段理论最大直流电流：Imax = Pd / Vf = 36 mW / 2.0 V ≈ 18 mA。建议设计时将峰值电流控制在不超过18 mA，以保证可靠性。常见驱动建议：
- 若使用 5 V 电源，目标段电流 If = 5 mA 时：串联电阻 R ≈ (5 − 2.0) / 0.005 ≈ 600 Ω（标准：560–620 Ω）；If = 10 mA 时 R ≈ 300 Ω。
- 若使用 3.3 V 电源，If = 5 mA 时 R ≈ 260 Ω（标准：240–270 Ω）。
注意：产品为共阳结构，驱动时共阳端接至VCC，段选用于下拉（低电平点亮）。多位显示常用扫描/复用方式以节约IO。
四、复用（多位扫描）注意事项
4位复用时单位占空比约25%，因此峰值电流 = 设定平均电流 / 占空比。举例：若目标平均亮度对应 5 mA，峰值将达到约 20 mA，已超过18 mA极限。建议：
- 将平均电流设定在 3–4 mA 区间（峰值 ≤ 16 mA）以延长寿命；或
- 使用限流与恒流驱动芯片，并使用低占空比下的短脉冲驱动时注意Pd与瞬时电流限制。
五、封装与安装建议
- 型式为穿孔DIP，推荐在PCB上预留对应30×14 mm安放空间并确认引脚间距与孔径；
- 焊接时采用合理的温度曲线，避免长时间高温直烙；
- 存储与装配过程中避免静电与机械冲击。
六、典型应用
适合家用电器面板、便携式测量仪表、电子钟表、电源显示、消费类产品的数值提示等场景，尤其在对成本与可视性有适中要求的嵌入式显示应用中表现良好。
总结：XL-DB3461SRBC以小尺寸、共阳封装和标准化DIP形式，提供便捷的穿孔安装与通用驱动方式。在设计时重点关注Pd/Imax限制与复用峰值电流，以保证亮度与可靠性的平衡。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
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.
