AR05BTCW3502 产品概述
一、产品简介
AR05BTCW3502 是 Viking（光颉）品牌的高精度薄膜贴片电阻，封装为 0805（约 2.0 × 1.25 mm）。额定功率 125 mW，阻值 35 kΩ，公差 ±0.1%，温度系数（TCR）为 ±25 ppm/℃，额定工作电压 150 V，工作温度范围 -55℃ 至 +155℃。该器件以精度高、温漂小和长期稳定性好为特点，适合精密电子与工业级应用。
二、主要特性
- 薄膜工艺：低噪声、低电阻漂移、优良的长期稳定性。
- 高精度：±0.1% 公差，适用于精密分压、电阻网络与参考电路。
- 低温漂：±25 ppm/℃，在宽温区间保持阻值稳定。
- 封装兼容性：0805 适合自动贴片和回流焊工艺，便于量产装配。
- 宽温工作范围：-55℃～+155℃，可满足工业级温度要求。
三、电气与热特性（要点）
- 额定功率：125 mW（注意需做功率降额与散热考虑）。
- 额定工作电压：150 V（指器件允许的最高工作电压，但需同时满足功率限制）。
- 实用提示：对于 35 kΩ 阻值，基于功率限制可计算最大允许电压 Vmax = sqrt(P × R) ≈ sqrt(0.125 × 35000) ≈ 66.1 V；在 150 V 直接施加将导致远超额定功率（约 0.64 W），因此使用时必须按功率而非标称工作电压选型。
四、典型应用
- 精密分压器、ADC/DAC 前端校准电路。
- 温度/压力传感器接口与信号调理。
- 仪器仪表、医疗电子与测量设备中需长期稳定阻值场合。
- 滤波网络与高阻抗偏置电路。
五、封装与装配建议
- 0805 尺寸（约 2.0 × 1.25 mm），适配常见贴片工艺。
- 与常规无铅回流兼容，建议遵循供应商回流曲线并避免多次超温循环。
- 存储与搬运时注意防潮、防污染，贴片电阻一般无可视标识，装配后请做好物料管理与追溯。
六、选型与使用注意
- 核查电路中实际电压/电流与功耗，确保在器件允许的功率范围内工作，并考虑环境温度造成的降额。
- 若用于高可靠或汽车级应用，需确认是否有相应认证或额外应力测试报告。
- 对阻值、温漂、长期稳定性有更高要求时，可与供应商确认批次性能与寿命测试数据。
如需更详细的电气参数、回流焊曲线、可靠性试验报告或样品订单信息，可提供具体需求以便进一步提供技术资料与支持。

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.
