XL-DB3361SRBC 产品概述
一、产品简介
XL-DB3361SRBC 是成兴光（Xinglight）推出的一款 3 位 7 段 LED 数码管，字符高度 0.36 英寸（约 9.1 mm），红色发光，采用共阳（共阳极）结构。封装为标准 DIP，外形尺寸约 22.5 × 14 mm，适用于面板显示、便携仪表、计数器、家用电器和各类电子指示场合。
二、主要规格
- 位数：3 位，7 段显示
- 字符尺寸：0.36 英寸（约 9.1 mm）
- 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（VF）：约 2.0 V（单段）
- 耗散功率（Pd）：36 mW（单段）
- 工作温度范围：-30 ℃ ~ +70 ℃
- 封装类型：DIP，尺寸约 22.5 × 14 mm
三、电气特性与驱动建议
根据标称 Pd（36 mW）与 VF（2.0 V），单段最大直流正向电流估算约为 18 mA（If_max ≈ Pd / VF）。为保证长期可靠性与亮度均匀，建议工作电流低于此极限。实际驱动策略可参考：
- 直接驱动（单位段）：若系统电源为 5 V，期望 If = 10 mA，则限流电阻 R ≈ (5 V − 2 V) / 10 mA = 300 Ω。
- 多位多路复用：若采用灯位扫描（3 位），注意占空比为 1/3，会使平均亮度下降，可适当提高峰值电流但应不超过估算的最大值并考虑热耗散与寿命。
- 共阳驱动：共阳端连接至正电源，段端由下拉或开集电极驱动，常用低侧驱动芯片或微控制器带限流电阻。
四、机械与封装
标准 DIP 封装便于通过插入或波峰/回流焊接安装，板上占用面积小，便于批量生产。封装尺寸（22.5×14 mm）适合面板窗口设计与固定结构配合。安装时注意针脚方向与共阳引脚识别，防止接反。
五、应用场景
适用于各类需要数字显示的场合，如家用电器面板、工业控制仪表、电量计数器、电子钟表、教学演示及消费类电子产品的状态指示等。红色高对比显示在弱光和一般室内照明下均具良好可视性。
六、使用注意事项与可靠性
- 焊接：建议采用推荐的焊接温度和时间，避免过长高温暴露导致 LED 损伤。
- ESD 防护：红色 LED 对静电敏感，装配与测试过程中应采取防静电措施。
- 清洗与化学品：避免使用强溶剂直接清洗显示面板，防止腐蚀导致亮度下降或透镜损伤。
- 环境与热管理：在高温或长时间高电流工作下注意散热与温升，超出工作温度范围会影响可靠性与寿命。
总结：XL-DB3361SRBC 以其适中的字符尺寸、标准 DIP 封装与共阳设计，提供稳定的红色数字显示解决方案。合理选择驱动电流与控制方式，可在多种应用中实现清晰、可靠的数字指示。

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.
